Section 9: 9.2 P601D Concrete - Swimming Pool Tank

Part 3 – Execution

3.1 Substrate Examination

A. Verify that surfaces to be covered with ceramic tile, mosaics, pavers, brick, stone, trim or waterproofing are:

1. Sound, rigid and conform to good design/engineering practices;

2. Systems, including the framing system and panels, over which tile or stone will be installed shall be in conformance with the International Residential Code (IRC) for residential applications, the International Building Code (IBC) for commercial applications, or applicable building codes. The project design should include the intended use and necessary allowances for the expected live load, concentrated load, impact load, and dead load including the weight of the finish and installation materials;

3. Clean and free of dust, dirt, oil, grease, sealers, curing compounds, laitance, efflorescence, form oil, loose plaster, paint, and scale;

4. Thin-set tile installations have a specified subsurface tolerance, for instance 1/4" in 10' (6 mm in 3 m) and 1/16" in 1' (1.5 mm in 300 mm), to conform with the ANSI specifications. Because thin-set is not intended to be used in truing or leveling the work of others, the subsurface typically should not vary by more than 1/16" over 1' (1.5 mm over 300 mm), nor more than 1/32" (0.8 mm) between adjoining edges where applicable (e.g. between sheets of exterior glue plywood or between adjacent concrete masonry units). Should the architect/designer require a more stringent tolerance (e.g. 1/8" in 10' [3 mm in 3 m]), the subsurface specification must reflect that tolerance, or the tile specification must include a specific and separate requirement to bring the 1/4" (6 mm) subsurface tolerance into compliance with the 1/8" (6 mm) tolerance desired;

5. Not leveled with gypsum or asphalt based compounds;

6. Dry as per American Society for Testing and Materials (ASTM) D4263 “Standard Test for Determining Moisture in Concrete by the Plastic Sheet Method.”

B. Concrete surfaces shall also be:

1. Cured a minimum of 28 days at 70°F (21°C), including an initial seven (7) day period of wet curing;

NOTE TO SPECIFIER: LATICRETE® latex portland cement mortars do not require a minimum cure time for concrete substrates or mortar beds;

2. Wood float finished, or better, if the installation is to be done by the thin bed method;

C. Advise General Contractor and Architect of any surface or substrate conditions requiring correction before tile work commences. Beginning of work constitutes acceptance of substrate or surface conditions.

3.2 Surface Preparation

A. Concrete Substrates – Concrete surface preparation shall be in accord with ACI 302. Sound and remove all loose concrete to firm substrate. Concrete surfaces shall be roughened to a concrete surface profile (CSP) of 3 to 5 (per ICRI CSP Standards 7 to 9 for acceptable profile height). Thoroughly wash/rinse with clean potable water. Surface defects or holes in the substrate shall be patched per manufacturer’s recommendations.

(Insert any Special Means of Preparation in addition to the surface preparation requirements listed in § 3.1)

B. (List other Substrates as required and means of preparation as required)

(Insert any Special Means of Preparation in addition to the surface preparation requirements listed in § 3.1)

C. At the conclusion of all surface preparation and prior to the installation of tile, measure the pH level of the substrate. Tile work will not commence until the pH has a value of 10 or less.

NOTE TO SPECIFIER: Edit substrate and preparation section based on project specific surfaces and conditions.

3.3 Installation – Accessories

NOTE TO SPECIFIER: Edit section based on project specific conditions.

3.4 Installation – Tile, Brick and Stone

A. General: Install in accordance with current versions of American National Standards Institute, Inc. (ANSI) “A108 American National Standard Specifications for Installation of Ceramic Tile” and TCNA “Handbook for Ceramic Tile Installation.” Cut and fit ceramic tile, brick or stone neatly around corners, fittings, and obstructions.

D. In addition to installing waterproofing membrane where required, provide proper architectural detailing, especially at critical areas such as any penetrations and copings.

NOTE TO SPECIFIER: Adhesives/mastics, mortars and grouts for ceramic tile, mosaics, pavers, brick and stone are not replacements for waterproofing membranes and will not prevent water penetration into occupied or storage spaces below. Drains must be a two-part clamping ring style drains with weepers and as per ASME A112.6.3. Place tile spacers or gravel around weep holes to prevent mortar from clogging the weep holes.

Pre-Treat Cracks and Joints – Fill all substrate cracks, cold joints and control joints to a smooth finish using a LATICRETE® latex-fortified thin-set. Alternatively, a liberal coat* of LATICRETE Hydro Ban applied with a paint brush or trowel may be used to fill in non-structural joints and cracks. Apply a liberal coat* of LATICRETE Hydro Ban approximately 8" (200 mm) wide over substrate cracks, cold joints, and control joints using a paint brush or heavy napped paint roller.

Pre-Treat Coves and Floor/Wall Intersections – Fill all substrate coves and floor/wall transitions to a smooth finish and changes in plane using a LATICRETE latex-fortified thin-set. Alternatively, a liberal coat* of LATICRETE Hydro Ban applied with a paint brush or trowel may be used to fill in cove joints and floor/wall transitions <1/8" (3 mm) in width. Apply a liberal coat* of LATICRETE Hydro Ban approximately 8" (200 mm) wide over substrate cracks, cold joints, and control joints using a paint brush or heavy napped paint roller.

Pre-Treat Drains – Drains must be of the clamping ring type, with weepers as per ASME A112.6.3. Apply a liberal coat* of LATICRETE Hydro Ban around and over the bottom half of drain clamping ring. Cover with a second liberal coat of LATICRETE Hydro Ban. When the LATICRETE Hydro Ban dries, apply a bead of LATICRETE Latasil where the LATICRETE Hydro Ban meets the drain throat. Install the top half of drain clamping ring.

Pre-Treat Penetrations – Allow for a minimum 1/8" (3 mm) space between drains, pipes, lights, or other penetrations and surrounding ceramic tile, stone or brick. Pack any gaps around pipes, lights or other penetrations with a LATICRETE latex-fortified thin-set. Apply a liberal coat* of LATICRETE Hydro Ban around penetration opening. Cover the first coat with a second liberal coat* of LATICRETE Hydro Ban. Bring LATICRETE Hydro Ban up to level of tile or stone. When LATICRETE Hydro Ban has dried to the touch seal with LATICRETE Latasil.

Main Application – Allow any pre-treated areas to dry to the touch. Apply a liberal coat* of LATICRETE Hydro Ban with a paint brush or heavy napped roller over substrate including pre-treated areas and allow to dry to the touch. Install another liberal coat* of LATICRETE Hydro Ban over the first coat. Let the top coat of LATICRETE Hydro Ban dry to the touch approximately 1 – 2 hours at 70°F (21°C) and 50% RH. When the top coat has dried to the touch inspect the surface for pinholes, voids, thin spots or other defects. LATICRETE Hydro Ban will dry to an olive green color when fully cured. Use additional LATICRETE Hydro Ban to seal any defects.

Movement Joints – Apply a liberal coat* of LATICRETE Hydro Ban, approximately 8" (200 mm) wide over the areas. Then embed and loop the 6" (150 mm) wide LATICRETE 9235 Waterproofing Membrane Reinforcing Fabric and allow the LATICRETE Hydro Ban liquid to bleed through. Immediately top coat with a second coat of LATICRETE Hydro Ban.

* Dry coat thickness is 20 – 30 mil (.02 – .03" or .5 – .8 mm); consumption per coat is approximately .01 gal/ft2 (approx. 0.4 m2); coverage is approximately 100 ft2 /gal (approx. 2.5 m2/. LATICRETE® Waterproofing/Anti-Fracture Fabric can be used to pre-treat cracks, joints, curves, corners, drains, and penetrations with LATICRETE Hydro Ban.

Protection – Provide protection for newly installed membrane, even if covered with a thin-bed ceramic tile, stone or brick installation against exposure to rain or other water for a minimum of 24 hours at 70°F (21°C) and 50% RH. For temperatures between 45°F and 69°F (7°C to 21°C) allow a 3 day cure period.

Flood Testing – Allow membrane to cure fully before flood testing, typically a minimum 2 hours at 70°F (21°C) and 50% RH. Cold conditions will require a longer curing time. For temperatures between 50°F and 69°F (10°C to 21°C) allow a minimum 24 hour cure period prior to flood testing. Please refer to LATICRETE TDS 169 “Flood Testing Procedures”, available at www.laticrete.com for flood testing requirements and procedures.

E. Thin Bed Method: At the conclusion of all surface preparation and prior to the installation of tile, measure the pH level of the substrate. Tile work will not commence until the pH has a value of 10 or less. Install latex portland cement mortar in compliance with current revisions of ANSI A108.02 (3.11), A108.1B and ANSI A108.5. Use the appropriate trowel notch size to ensure proper bedding of the tile, brick or stone selected. Work the latex portland cement mortar into good contact with the substrate and comb with notched side of trowel. Spread only as much latex portland cement mortar as can be covered while the mortar surface is still wet and tacky. When installing large format (>8" × 8"/200 mm × 200 mm) tile/stone, rib/button/lug back tiles, pavers or sheet mounted ceramics/mosaics, spread latex portland cement mortar onto the back of (i.e. ‘back-butter’) each piece/sheet in addition to trowelling latex portland cement mortar over the substrate. Beat each piece/sheet into the latex portland cement mortar with a beating block or rubber mallet to insure full bedding and flatness. Allow installation to set until firm. Clean excess latex portland cement mortar from tile or stone face and joints between pieces.

F. Grouting or Pointing:

NOTE TO SPECIFIER: select one of following and specify color for each type/color of ceramic tile, mosaic, paver, trim unit:

1. Chemical Resistant, Water Cleanable Tile-Grouting Epoxy (ANSI A118.3): Follow manufacturer’s recommendations for minimum cure time prior to grouting. Store liquid components of LATICRETE SpectraLOCK® PRO Grout* for 24 hours at 70–80°F (21–27°C) prior to use to facilitate mixing and application. Substrate temperature must be 40–95°F (4–35°C). Verify joints are free of dirt, debris or grout spacers. Sponge or wipe dust/dirt off tile faces and remove water standing in joints. Apply grout release to face of absorptive, abrasive, non-slip or rough textured ceramic tile, pavers, bricks, stone or trim units that are not hot paraffin coated to facilitate cleaning. Cut open pouch and pour LATICRETE SpectraLOCK PRO Grout Part A Liquid into a clean mixing pail. Then open pouch and pour LATICRETE SpectraLOCK PRO Grout Part B Liquid into the mixing pail. Mix by hand or with a slow speed (<300 rpm) mixer until the two liquids are well blended. Then, while mixing, add LATICRETE SpectraLOCK PRO Grout Part C Powder and blend until uniform. Install LATICRETE SpectraLOCK PRO Grout in compliance with current revisions of ANSI A108.02 (3.13) and ANSI A108.6 (3.0 – 4.0). Spread using a sharp edged, hard rubber float and work grout into joints. Using strokes diagonal (at 45° angle) to the grout lines, pack joints full and free of voids/pits. Then hold float face at a 90° angle to grouted surface and use float edge to "squeegee" off excess grout, stroking diagonally to avoid pulling grout out of filled joints. Once excess grout is removed, a thin film/haze will be left. Initial cleaning of the remaining film/haze can begin approximately 20–30 minutes after grouting (wait longer at colder temperatures). Begin by mixing cleaning additive packet with 2 gallons (7.6 of clean water in a clean bucket to make cleaning solution. Dip a clean sponge into the bucket and then wring out cleaning solution until sponge is damp. Using a circular motion, lightly scrub grouted surfaces with the damp sponge to dissolve grout film/haze. Then drag sponge diagonally over the scrubbed surfaces to remove froth. Rinse sponge frequently and change cleaning solution at least every 50 ft2 (4.7 m2). Discard sponges as they become "gummy" with residue. Within one (1) hour of finishing first cleaning, clean the same area again following the same procedure but utilizing a clean white scrub pad and fresh cleaning solution. Rinse scrub pad frequently. Drag a clean sponge diagonally over the scrubbed surfaces to remove froth. Use each side of sponge only once before rinsing and change cleaning solution at least every 50 ft2 (4.7m2). Allow cleaned areas to dry and inspect tile/stone surface. For persistent grout film/haze (within 24 hours), repeat scrubbing procedure with undiluted white vinegar and clean pad. Rinse with clean water and allow surface to dry. Inspect grout joint for pinholes/voids and repair them with freshly mixed LATICRETE® SpectraLOCK® PRO Grout. Cautions: Do not use undiluted white vinegar on polished marble or limestone unless a test spot in an inconspicuous area indicates no change in finish appearance; do not use acid cleaners on epoxy grout less than 7 days old.

2. Polymer Fortified Cement Grout (ANSI A118.7): Allow ceramic tile, mosaics, pavers, brick or stone installation to cure a minimum of 24 hours at 70°F (21°C). Verify grout joints are free of dirt, debris or tile spacers. Sponge or wipe dust/dirt off veneer face and remove any water standing in joints. Apply grout release to face of absorptive, abrasive, non-slip or rough textured ceramic tile, pavers, bricks, or trim units that are not hot paraffin coated to facilitate cleaning. Surface temperature must be between 40–90°F (4–32°C). Pour approximately 64 oz (1.9 of clean, potable water into a clean mixing container. Add a 25 lb (11.3 kg) bag of LATICRETE PermaColor Grout^ to the container while mixing. Mix by hand or with a slow speed mixer to a smooth, stiff consistency. Install latex fortified cement grout in compliance with current revisions of ANSI A108.1A (7.0 Grouting of tile), ANSI A108.02 (4.5 Cleaning tile) and ANSI A108.10. Dampen dry surfaces with clean water. Spread using a sharp edged, hard rubber float and work grout into joints. Using diagonal (at 45° angle to direction of grout line) strokes, pack joints full and free of voids/pits. Hold float face at a 90° angle to grouted surface and use float edge to "squeegee" off excess grout, stroking diagonally to reduce pulling grout out of filled joints. Initial cleaning can begin as soon as grout has become firm, typically 15–20 minutes after grouting at 70°F (21°C). Higher temperatures may require faster time to initial cleaning; wider joints or lower temperatures may require a longer time to initial cleaning. Begin initial cleaning by lightly dampening the entire grouted area with a damp sponge. Then wash clean the entire area with a damp (not wet) sponge. Drag a clean towel, dampened with water, or wipe a clean, dampened sponge, diagonally over the veneer face to remove any grout haze left after “squeegeeing.” Rinse towel/sponge frequently and change rinse water at least every 200 ft2 (19 m2). Repeat this cleaning sequence again if grout haze is still present. Allow grout joints to become firm. Buff surface of grout with clean coarse cloth. Inspect joint for pinholes/voids and repair them with freshly mixed grout. Within 24 hours, check for remaining haze and remove it with warm soapy water and a nylon scrubbing pad, using a circular motion, to lightly scrub surfaces and dissolve haze/film. Do not use acid cleaners on latex portland cement grout less than 10 days old.

NOTE TO SPECIFIER: Select one of following and specify color for each type/color of ceramic tile, mosaic, paver, trim unit:

1. Latex-portland cement sanded floor grout for joint widths ≥1/16" (1.5 mm) and ≤1/2" (12 mm);

2. Latex-portland cement unsanded grout for soft glazed tiles and soft/polished stone with joints widths ≤1/8" (3 mm).

G. Expansion and Control Joints: Architect must specify type of joint and show location and details on drawings.

Provide control or expansion joints as located in contract drawings and in full conformity, especially in width and depth, with architectural details.

1. Substrate joints must carry through, full width, to surface of tile, brick or stone.

2. Install expansion joints in tile, brick or stone work over construction/cold joints or control joints in substrates.

3. Install expansion joints where tile, brick or stone abut restraining surfaces (such as perimeter walls, curbs, columns), changes in plane and corners.

4. Joint width and spacing depends on application – follow TCNA “Handbook for Ceramic Tile Installation” Detail "EJ-171 Expansion Joints" or consult sealant manufacturer for recommendation based on project parameters.

5. Joint width: ≥1/8" (3 mm) and ≤1" (25 mm).

6. Joint width: depth ~2:1 but joint depth must be ≥1/8" (3 mm) and ≤1/2" (12 mm).

7. Layout (field defined by joints): 1:1 length: width is optimum but must be ≤ 2:1. Remove all contaminants and foreign material from joint spaces/surfaces, such as dirt, dust, oil, water, frost, setting/grouting materials, sealers and old sealant/backer. Use LATICRETE Latasil 9118 Primer for underwater and permanent wet area applications, or for porous stone (e.g. limestone, sandstone etc…) installations. Install appropriate backing material (e.g. closed cell backer rod) based on expansion joint design and as specified in § 07920. Apply masking tape to face of tile, brick or stone veneer. Use caulking gun, or other applicator, to completely fill joints with sealant. Within 5–10 minutes of filling joint, ‘tool’ sealant surface to a smooth finish. Remove masking tape immediately after tooling joint. Wipe smears or excess sealant off the face of non-glazed tile, brick, stone or other absorptive surfaces immediately.

H. Adjusting: Correction of defective work for a period of one (1) year following substantial completion, return to job and correct all defective work. Defective work includes, without limitation, tiles broken in normal abuse due to deficiencies in setting bed, loose tiles or grout, and all other defects which may develop as a result of poor workmanship.

3.5 Cleaning

Clean excess mortar/epoxy from veneer surfaces with water before they harden and as work progresses. Do not contaminate open grout/caulk joints while cleaning. Sponge and wash veneers diagonally across joints. Do not use acids for cleaning. Polish with clean dry cloth. Remove surplus materials and leave premises broom clean.

3.6 Protection

Protect finished installation under provisions of §01500 and §01535. Close areas to other trades and traffic until tile being installed has set firmly. Keep floors installed with epoxy adhesive closed to traffic for 24 hrs at 70°F (21°C), and to heavy traffic for 48 hours at 70°F (21°C) unless instructed differently by manufacturer. Use kneeling boards, or equivalent, to walk/work on newly tiled floors. Cure tile work in swimming pools, fountains and other continuous immersion applications for 10 days for epoxy based grout at 70°F (21°C) and 14 days for latex-portland cement based grout at 70°F (21°C) before filling installation with water. Extend period of protection at lower temperatures, below 60°F (16°C) and at high relative humidity (>70% RH) due to retarded set times of mortar/adhesives. Replace or restore work of other trades damaged or soiled by work under this section.

Filling Pool – Maintain a differential of 10°F (5.5°C) or less between the fill water and substrate temperatures during fill and drain cycles, and fill pool with water at rate of 2' (600 mm) per 24 hours to allow gradual exposure to water pressure, thermal and moisture differentials. Initial alkalinity of pool water is very high from exposure to portland cement based finishes, grouts, and mortars; careful and frequent balance is required. Do not fill if potential thermal gradients exist (very cold source water, exterior pool exposed to several days of solar radiation, etc…).

Emptying Pool – empty pool water at rate of 2' (600 mm) per 24 hours to prevent hydrostatic pressure from de-laminating tiles of leveling mortar (in pools without waterproof membrane).

4. Thin-set tile installations have a specified subsurface tolerance, for instance 1/4" in 10' (6 mm in 3 m) and 1/16" in 1' (1.5 mm in 300 mm), to conform with the ANSI specifications. Because thin-set is not intended to be used in truing or leveling the work of others, the subsurface typically should not vary by more than 1/16" over 1' (1.5 mm over 300 mm), nor more than 1/32" (0.8 mm) between adjoining edges where applicable (e.g. between sheets of exterior glue plywood or between adjacent concrete masonry units). Should the architect/designer require a more stringent tolerance (e.g. 1/8" in 10' [3 mm in 3 m]), the subsurface specification must reflect that tolerance, or the tile specification must include a specific and separate requirement to bring the 1/4" (6 mm) subsurface tolerance into compliance with the 1/8" (6 mm) tolerance desired;

5. Not leveled with gypsum or asphalt based compounds;

6. Dry as per American Society for Testing and Materials (ASTM) D4263 “Standard Test for Determining Moisture in Concrete by the Plastic Sheet Method.”

B. Concrete surfaces shall also be:

1. Cured a minimum of 28 days at 70°F (21°C), including an initial seven (7) day period of wet curing;

2. Wood float finished, or better, if the installation is to be done by the thin bed method;

C. Advise General Contractor and Architect of any surface or substrate conditions requiring correction before tile work commences. Beginning of work constitutes acceptance of substrate or surface conditions.

3.2 Surface Preparation

A. Concrete Substrate – Concrete surface preparation shall be in accord with ACI 302. Sound and remove all loose concrete to firm substrate. Concrete surfaces shall be roughened to a concrete surface profile (CSP) of 3 to 5 (per ICRI CSP Standards 7 to 9 for acceptable profile height). Thoroughly wash/rinse with clean potable water. Surface defects or holes in the substrate shall be patched per manufacturer’s recommendations.

(Insert any Special Means of Preparation in addition to the surface preparation requirements listed in § 3.1)

B. (List other Substrates as required and means of preparation as required)

(Insert any Special Means of Preparation in addition to the surface preparation requirements listed in § 3.1)

C. At the conclusion of all surface preparation and prior to the installation of tile, measure the pH level of the substrate. Tile work will not commence until the pH has a value of 10 or less.

NOTE TO SPECIFIER: Edit substrate and preparation section based on project specific surfaces and conditions.

3.3 Installation – Accessories

A. Waterproofing:

NOTE TO SPECIFIER: Adhesives/mastics, mortars and grouts for ceramic tile, mosaics, pavers, brick and stone are not replacements for waterproofing membranes and will not prevent water penetration into occupied or storage spaces below.

Install the waterproofing membrane in compliance with current revisions of ANSI A108.1 (2.7 Waterproofing) and ANSI A108.13. Review the installation and plan the application sequence.

Pre-cut LATICRETE® Waterproofing/Anti-Fracture Fabric (if required), allowing 2" (50 mm) for overlap at ends and sides to fit the areas as required. Roll up the pieces for easy handling and placement. Shake or stir LATICRETE Hydro Ban before using.

Pre-Treat Cracks and Joints – Fill all substrate cracks, cold joints and control joints to a smooth finish using a LATICRETE latex-fortified thin-set. Alternatively, a liberal coat* of LATICRETE Hydro Ban applied with a paint brush or trowel may be used to fill in non-structural joints and cracks. Apply a liberal coat* of LATICRETE Hydro Ban approximately 8" (200 mm) wide over substrate cracks, cold joints, and control joints using a paint brush or heavy napped paint roller.

Pre-Treat Coves and Floor/Wall Intersections – Fill all substrate coves and floor/wall transitions to a smooth finish and changes in plane using a LATICRETE latex-fortified thin-set. Alternatively, a liberal coat* of LATICRETE Hydro Ban applied with a paint brush or trowel may be used to fill in cove joints and floor/wall transitions <1/8" (3mm) in width. Apply a liberal coat* of LATICRETE Hydro Ban approximately 8" (200 mm) wide over substrate cracks, cold joints, and control joints using a paint brush or heavy napped paint roller.

Pre-Treat Drains – Drains must be of the clamping ring type, with weepers as per ASME A112.6.3. Apply a liberal coat* of LATICRETE Hydro Ban around and over the bottom half of drain clamping ring. Cover with a second liberal coat of LATICRETE Hydro Ban. When the LATICRETE Hydro Ban dries, apply a bead of LATICRETE Latasil where the LATICRETE Hydro Ban meets the drain throat. Install the top half of drain clamping ring.

Pre-Treat Penetrations – Allow for a minimum 1/8" (3 mm) space between drains, pipes, lights, or other penetrations and surrounding ceramic tile, stone or brick. Pack any gaps around pipes, lights or other penetrations with a LATICRETE latex-fortified thin-set. Apply a liberal coat* of LATICRETE Hydro Ban around penetration opening. Cover the first coat with a second liberal coat* of LATICRETE Hydro Ban. Bring LATICRETE Hydro Ban up to level of tile or stone. When LATICRETE Hydro Ban has dried to the touch seal with LATICRETE Latasil.

Main Application – Allow any pre-treated areas to dry to the touch. Apply a liberal coat* of LATICRETE Hydro Ban with a paint brush or heavy napped roller over substrate including pre-treated areas and allow to dry to the touch. Install another liberal coat* of LATICRETE Hydro Ban over the first coat. Let the top coat of LATICRETE Hydro Ban dry to the touch approximately 1 – 2 hours at 70°F (21°C) and 50% RH. When the top coat has dried to the touch inspect the surface for pinholes, voids, thin spots or other defects. LATICRETE Hydro Ban will dry to an olive green color when fully cured. Use additional LATICRETE Hydro Ban to seal any defects.

Movement Joints – Apply a liberal coat* of LATICRETE Hydro Ban, approximately 8" (200mm) wide over the areas. Then embed and loop the 6" (150 mm) wide LATICRETE Waterproofing/Anti-Fracture Fabric and allow the LATICRETE Hydro Ban liquid to bleed through. Immediately apply a second coat of LATICRETE Hydro Ban.

 *  Dry coat thickness is 20 – 30 mil (0.02 – 0.03" or 0.5 – 0.8 mm); consumption per coat is approximately 0.01 gal/ft2 (approx. 0.4 m2); coverage is approximately 100 ft2 /gal (approx. 2.5 m2/. LATICRETE® Waterproofing/Anti-Fracture Fabric can be used to pre-treat cracks, joints, curves, corners, drains, and penetrations with LATICRETE Hydro Ban.

Protection – Provide protection for newly installed membrane, even if covered with a thin-bed ceramic tile, stone or brick installation against exposure to rain or other water for a minimum of 2 hours at 70°F (21°C) and 50% RH. For temperatures between 45°F and 69°F (7°C to 21°C) allow a minimum 24 hour cure period.

Flood Testing – Allow membrane to cure fully before flood testing, typically a minimum 2 hours at 70°F (21°C) and 50% RH. Cold conditions will require a longer curing time. For temperatures between 50°F and 69°F (10°C to 21°C) allow a minimum 24 hour cure period prior to flood testing.

C. Thin Bed Method: At the conclusion of all surface preparation and prior to the installation of tile, measure the pH level of the substrate. Tile work will not commence until the pH has a value of 10 or less. Install latex portland cement mortar in compliance with current revisions of ANSI A108.02 (3.11), A108.1B and ANSI A108.5. Use the appropriate trowel notch size to ensure proper bedding of the tile, brick or stone selected. Work the latex portland cement mortar into good contact with the substrate and comb with notched side of trowel. Spread only as much latex portland cement mortar as can be covered while the mortar surface is still wet and tacky. When installing large format (>8" × 8"/200 mm × 200 mm) tile/stone, rib/button/lug back tiles, pavers or sheet mounted ceramics/mosaics, spread latex portland cement mortar onto the back of (i.e. ‘back-butter’) each piece/sheet in addition to trowelling latex portland cement mortar over the substrate. Beat each piece/sheet into the latex portland cement mortar with a beating block or rubber mallet to insure full bedding and flatness. Allow installation to set until firm. Clean excess latex portland cement mortar from tile or stone face and joints between pieces.

D. Grouting or Pointing:

NOTE TO SPECIFIER: Select one of following and specify color for each type/color of ceramic tile, mosaic, paver, trim unit:

1. Chemical Resistant, Water Cleanable Tile-Grouting Epoxy (ANSI A118.3): Follow manufacturer’s recommendations for minimum cure time prior to grouting. Store liquid components of LATICRETE® SpectraLOCK® PRO Grout* for 24 hours at 70–80°F (21–27°C) prior to use to facilitate mixing and application. Substrate temperature must be 40–95°F (4–35°C). Verify joints are free of dirt, debris or grout spacers. Sponge or wipe dust/dirt off tile faces and remove water standing in joints. Apply grout release to face of absorptive, abrasive, non-slip or rough textured ceramic tile, pavers, bricks, stone or trim units that are not hot paraffin coated to facilitate cleaning. Cut open pouch and pour LATICRETE SpectraLOCK PRO Grout Part A Liquid into a clean mixing pail. Then open pouch and pour LATICRETE SpectraLOCK PRO Grout Part B Liquid into the mixing pail. Mix by hand or with a slow speed (<300 rpm) mixer until the two liquids are well blended. Then, while mixing, add LATICRETE SpectraLOCK PRO Grout Part C Powder and blend until uniform. Install LATICRETE SpectraLOCK PRO Grout in compliance with current revisions of ANSI A108.02 (3.13) and ANSI A108.6 (3.0 – 4.0). Spread using a sharp edged, hard rubber float and work grout into joints. Using strokes diagonal (at 45° angle) to the grout lines, pack joints full and free of voids/pits. Then hold float face at a 90° angle to grouted surface and use float edge to "squeegee" off excess grout, stroking diagonally to avoid pulling grout out of filled joints. Once excess grout is removed, a thin film/haze will be left. Initial cleaning of the remaining film/haze can begin approximately 20–30 minutes after grouting (wait longer at colder temperatures). Begin by mixing cleaning additive packet with 2 gallons (7.6 of clean water in a clean bucket to make cleaning solution. Dip a clean sponge into the bucket and then wring out cleaning solution until sponge is damp. Using a circular motion, lightly scrub grouted surfaces with the damp sponge to dissolve grout film/haze. Then drag sponge diagonally over the scrubbed surfaces to remove froth. Rinse sponge frequently and change cleaning solution at least every 50 ft2 (4.7m2). Discard sponges as they become "gummy" with residue. Within one (1) hour of finishing first cleaning, clean the same area again following the same procedure but utilizing a clean white scrub pad and fresh cleaning solution. Rinse scrub pad frequently. Drag a clean sponge diagonally over the scrubbed surfaces to remove froth. Use each side of sponge only once before rinsing and change cleaning solution at least every 50 ft2 (4.7 m2). Allow cleaned areas to dry and inspect tile/stone surface. For persistent grout film/haze (within 24 hours), repeat scrubbing procedure with undiluted white vinegar and clean pad. Rinse with clean water and allow surface to dry. Inspect grout joint for pinholes/voids and repair them with freshly mixed LATICRETE® SpectraLOCK® PRO Grout. Cautions: Do not use undiluted white vinegar on polished marble or limestone unless a test spot in an inconspicuous area indicates no change in finish appearance; do not use acid cleaners on epoxy grout less than 7 days old.

2. Polymer Modified Cement Grout (ANSI A118.7): Allow ceramic tile, mosaics, pavers, brick or stone installation to cure a minimum of 24 hours at 70°F (21°C). Verify grout joints are free of dirt, debris or tile spacers. Sponge or wipe dust/dirt off veneer face and remove any water standing in joints. Apply grout release to face of absorptive, abrasive, non-slip or rough textured ceramic tile, pavers, bricks, or trim units that are not hot paraffin coated to facilitate cleaning. Surface temperature must be between 40–90°F (4–32°C). Pour approximately 64 oz (1.9 of clean, potable water into a clean mixing container. Add a 25 lb. (11.3 kg) bag of LATICRETE PermaColor Grout^ to the container while mixing. Mix by hand or with a slow speed mixer to a smooth, stiff consistency. Install latex fortified cement grout in compliance with current revisions of ANSI A108.1A (7.0 Grouting of tile), ANSI A108.02 (4.5 Cleaning tile) and ANSI A108.10. Dampen dry surfaces with clean water. Spread using a sharp edged, hard rubber float and work grout into joints. Using diagonal (at 45° angle to direction of grout line) strokes, pack joints full and free of voids/pits. Hold float face at a 90° angle to grouted surface and use float edge to "squeegee" off excess grout, stroking diagonally to reduce pulling grout out of filled joints. Initial cleaning can begin as soon as grout has become firm, typically 15–20 minutes after grouting at 70°F (21°C). Higher temperatures may require faster time to initial cleaning; wider joints or lower temperatures may require a longer time to initial cleaning. Begin initial cleaning by lightly dampening the entire grouted area with a damp sponge. Then wash clean the entire area with a damp (not wet) sponge. Drag a clean towel, dampened with water, or wipe a clean, dampened sponge, diagonally over the veneer face to remove any grout haze left after “squeegeeing.” Rinse towel/sponge frequently and change rinse water at least every 200 ft2 (19 m2). Repeat this cleaning sequence again if grout haze is still present. Allow grout joints to become firm. Buff surface of grout with clean coarse cloth. Inspect joint for pinholes/voids and repair them with freshly mixed grout. Within 24 hours, check for remaining haze and remove it with warm soapy water and a nylon scrubbing pad, using a circular motion, to lightly scrub surfaces and dissolve haze/film. Do not use acid cleaners on latex portland cement grout less than 10 days old.

NOTE TO SPECIFIER: Select one of following and specify color for each type/color of ceramic tile, mosaic, paver, trim unit:

1. Latex-portland cement sanded floor grout for joint widths ≥1/16" (1.5 mm ) and ≤1/2" (12 mm);

2. Latex-portland cement unsanded grout for soft glazed tiles and soft/polished stone with joints widths ≤1/8" (3 mm).

E. Expansion and Control Joints: Architect must specify type of joint and show location and details on drawings.

Provide control or expansion joints as located in contract drawings and in full conformity, especially in width and depth, with architectural details.

1. Substrate joints must carry through, full width, to surface of tile, brick or stone.

2. Install expansion joints in tile, brick or stone work over construction/cold joints or control joints in substrates.

3. Install expansion joints where tile, brick or stone abut restraining surfaces (such as perimeter walls, curbs, columns), changes in plane and corners.

4. Joint width and spacing depends on application – follow TCNA “Handbook for Ceramic Tile Installation” Detail "EJ-171 Expansion Joints" or consult sealant manufacturer for recommendation based on project parameters.

5. Joint width: ≥1/8" (3mm) and ≤1" (25 mm).

6. Joint width: depth ~2:1 but joint depth must be ≥1/8" (3mm) and ≤1/2" (12 mm).

7. Layout (field defined by joints): 1:1 length: width is optimum but must be ≤2:1. Remove all contaminants and foreign material from joint spaces/surfaces, such as dirt, dust, oil, water, frost, setting/grouting materials, sealers and old sealant/backer. Use LATICRETE Latasil 9118 Primer for underwater and permanent wet area applications, or for porous stone (e.g. limestone, sandstone etc…) installations. Install appropriate backing material (e.g. closed cell backer rod) based on expansion joint design and as specified in § 07920. Apply masking tape to face of tile, brick or stone veneer. Use caulking gun, or other applicator, to completely fill joints with sealant. Within 5–10 minutes of filling joint, ‘tool’ sealant surface to a smooth finish. Remove masking tape immediately after tooling joint. Wipe smears or excess sealant off the face of non-glazed tile, brick, stone or other absorptive surfaces immediately.

F. Adjusting: Correction of defective work for a period of one (1) year following substantial completion, return to job and correct all defective work. Defective work includes, without limitation, tiles broken in normal abuse due to deficiencies in setting bed, loose tiles or grout, and all other defects which may develop as a result of poor workmanship.

3.5. Protection

Protect finished installation under provisions of §01500 and §01535. Close areas to other trades and traffic until tile being installed has set firmly. Keep floors installed with epoxy adhesive closed to traffic for 24 hrs at 70°F (21°C), and to heavy traffic for 48 hrs at 70°F (21°C) unless instructed differently by manufacturer. Use kneeling boards, or equivalent, to walk/work on newly tiled floors. Cure tile work in swimming pools, fountains and other continuous immersion applications for 10 days for epoxy based grout at 70°F (21°C) and 14 days for latex-portland cement based grout at 70°F (21°C) before filling installation with water. Extend period of protection at lower temperatures, below 60°F (16°C) and at high relative humidity (>70% RH) due to retarded set times of mortar/adhesives. Replace or restore work of other trades damaged or soiled by work under this section.

Filling Pool – Maintain a differential of 10°F (5.5°C) or less between the fill water and substrate temperatures during fill and drain cycles, and fill pool with water at rate of 2' (600 mm) per 24 hrs to allow gradual exposure to water pressure, thermal and moisture differentials. Initial alkalinity of pool water is very high from exposure to portland cement based finishes, grouts, and mortars; careful and frequent balance is required. Do not fill if potential thermal gradients exist (very cold source water, exterior pool exposed to several days of solar radiation, etc…).

Emptying Pool – empty pool water at rate of 2' (600 mm) per 24 hrs to prevent hydrostatic pressure from de-laminating tiles of leveling mortar (in pools without waterproof membrane)

3.6 Cleaning

Clean excess mortar/epoxy from veneer surfaces with water before they harden and as work progresses. Do not contaminate open grout/caulk joints while cleaning. Sponge and wash veneers diagonally across joints. Do not use acids for cleaning. Polish with clean dry cloth. Remove surplus materials and leave premises broom clean.

Part 4 – Health and Safety

The use of personal protection such as rubber gloves, suitable dust masks, safety glasses and industrial clothing is highly recommended. Discarded packaging, product wash and waste water should be disposed of as per local, state or federal regulations.

Section 9: 9.4 P602 Steel Shell - Pool/Spa Thin Bed

Part 3 – Execution

3.1 Substrate Examination

A. Verify that surfaces to be covered with ceramic tile, mosaics, pavers, brick, stone, trim or waterproofing are:

1. Sound, rigid and conform to good design/engineering practices;

2. Systems, including the framing system and panels, over which tile or stone will be installed shall be in conformance with the International Residential Code (IRC) for residential applications, the International Building Code (IBC) for commercial applications, or applicable building codes. The project design should include the intended use and necessary allowances for the expected live load, concentrated load, impact load, and dead load including the weight of the finish and installation materials;

3. Clean and free of dust, dirt, oil, grease, sealers, curing compounds, laitance, efflorescence, form oil, loose plaster, paint, and scale;

4. Thin-set tile installations have a specified subsurface tolerance, for instance 1/4" in 10' (6 mm in 3 m) and 1/16" in 1' (1.5 mm in 300 mm), to conform with the ANSI specifications. Because thin-set is not intended to be used in truing or leveling the work of others, the subsurface typically should not vary by more than 1/16" over 1' (1.5 mm over 300 mm), nor more than 1/32" (0.8 mm) between adjoining edges where applicable (e.g. between sheets of exterior glue plywood or between adjacent concrete masonry units). Should the architect/designer require a more stringent tolerance (e.g. 1/8" in 10' [3 mm in 3 m]), the subsurface specification must reflect that tolerance, or the tile specification must include a specific and separate requirement to bring the 1/4" (6 mm) subsurface tolerance into compliance with the 1/8" (6 mm) tolerance desired;

5. Not leveled with gypsum or asphalt based compounds;

6. Dry as per American Society for Testing and Materials (ASTM) D4263 “Standard Test for Determining Moisture in Concrete by the Plastic Sheet Method.”

B. Concrete surfaces shall also be:

1. Cured a minimum of 28 days at 70°F (21°C), including an initial seven (7) day period of wet curing;

NOTE TO SPECIFIER: LATICRETE® Latex Portland Cement Mortars do not require a minimum cure time for concrete substrates or mortar beds;

2. Wood float finished, or better, if the installation is to be done by the thin bed method;

C. Advise General Contractor and Architect of any surface or substrate conditions requiring correction before tile work commences. Beginning of work constitutes acceptance of substrate or surface conditions.

3.2 Surface Preparation

A. Steel Surfaces

Steel or metal must be stainless or galvanized for this method. Wash steel surfaces with strong detergent to ensure that all manufacturing oils are removed; rinse completely and allow to dry. If possible, scuff steel surface with sandpaper or emery cloth and then re-wash steel, rinse completely and allow to dry.

B. Concrete Substrates

(Insert any Special Means of Preparation – In addition to the surface preparation requirements listed above; …)

C. (List other Substrates as required and means of preparation as required)

(Insert any Special Means of Preparation – In addition to the surface preparation requirements listed above; …)

3.3 Installation – Accessories

A. Waterproofing:

NOTE TO SPECIFIER: Adhesives/mastics, mortars and grouts for ceramic tile, mosaics, pavers, brick and stone are not replacements for waterproofing membranes and will not prevent water penetration into occupied or storage spaces below.

Install the waterproofing membrane in compliance with current revisions of ANSI A108.01 (2.7 Waterproofing) and ANSI A108.13. Review the installation and plan the application sequence. Main application: apply product to steel substrate using 3/16" × 5/32" v-notch trowel. Allow the trowel to gauge the appropriate amount of material onto the surface using the v-notch side. Once material is applied, use the flat side of the trowel to “knock down” or flatten all ridges to produce a smooth, flat surface. Be sure to look for any “pinholes” or areas not covered by the material. If any voids appear, cover same or next day with LATAPOXY® Waterproof Flashing Mortar. Make sure all 90° angles at coves and corners are properly filled.

Drain and pipe penetrations: Make sure that pipes and drains are free from rust, oil, dirt, and any other contaminants that might prevent adequate bonding. For PVC penetrations, scarify pipe with sandpaper where membrane will be applied. Ensure that pipes and drains are securely fastened, stable, rigid, and do not allow movement. Pack all voids around pipes or penetrations with closed cell backer rod in appropriate manner. Apply LATAPOXY Waterproof Flashing Mortar directly to the pipe penetration, extending 3 inches above point of installation. No fabric or sealant is required. The membrane will bond directly to the pipe. Ensure that proper thickness of 1mm (40mil) is achieved. For metal drains, flash LATAPOXY Waterproof Flashing Mortar directly over metal flange of drain – do not cover the weep holes. A two-part clamping ring style drain should be used.

3.4 Installation – Tile, Brick and Stone

A. General: Install in accordance with current versions of American National Standards Institute, Inc. (ANSI) “A108 American National Standard Specifications for Installation of Ceramic Tile” and TCNA “Handbook for Ceramic Tile Installation.” Cut and fit ceramic tile, brick or stone neatly around corners, fittings, and obstructions. Perimeter pieces to be minimum half tile, brick or stone. Chipped, cracked, split pieces and edges are not acceptable. Make joints even, straight, plumb and of uniform width to tolerance +/- 1/16" over 8' (1.5 mm in 2.4 m). Install divider strips at junction of flooring and dissimilar materials.

B. Thin Bed Method: Install epoxy adhesive in compliance with current revisions of ANSI A108.02 (3.11) and ANSI A108.6. Use the appropriate trowel notch size to ensure proper bedding of the tile or stone selected. Work the epoxy adhesive into good contact with the substrate and comb with notched side of trowel. Spread only as much epoxy adhesive as can be covered while the adhesive surface is still wet and tacky. When installing large format (>8" × 8"/ 200 mm × 200 mm) tile/stone, rib/button/lug back tiles, pavers or sheet mounted ceramics/mosaics, spread epoxy adhesive onto the back of (i.e. ‘back-butter’) each piece/sheet in addition to trowelling epoxy adhesive over the substrate. Beat each piece/sheet into the epoxy adhesive with a beating block or rubber mallet to insure full bedding and flatness. Allow installation to set until firm. Clean excess epoxy adhesive from tile or stone face and joints between pieces.

C. Grouting or Pointing:

NOTE TO SPECIFIER: Select one of following and specify color for each type/color of ceramic tile, mosaic, paver, trim unit:

1. Chemical Resistant, Water Cleanable Tile-Grouting Epoxy (ANSI A118.3): Follow manufacturer’s recommendations for minimum cure time prior to grouting. Store liquid components of LATICRETE® SpectraLOCK® PRO Grout* for 24 hours at 70–80°F (21–27°C) prior to use to facilitate mixing and application. Substrate temperature must be 40–95°F (4–35°C). Verify joints are free of dirt, debris or grout spacers. Sponge or wipe dust/dirt off tile faces and remove water standing in joints. Apply grout release to face of absorptive, abrasive, non-slip or rough textured ceramic tile, pavers, bricks, stone or trim units that are not hot paraffin coated to facilitate cleaning. Cut open pouch and pour LATICRETE SpectraLOCK PRO Grout Part A Liquid into a clean mixing pail. Then open pouch and pour LATICRETE SpectraLOCK PRO Grout Part B Liquid into the mixing pail. Mix by hand or with a slow speed (<300 rpm) mixer until the two liquids are well blended. Then, while mixing, add LATICRETE SpectraLOCK PRO Grout Part C Powder and blend until uniform. Install LATICRETE SpectraLOCK PRO Grout in compliance with current revisions of ANSI A108.02 (3.13) and ANSI A108.6 (3.0 – 4.0). Spread using a sharp edged, hard rubber float and work grout into joints. Using strokes diagonal (at 45° angle) to the grout lines, pack joints full and free of voids/pits. Then hold float face at a 90° angle to grouted surface and use float edge to "squeegee" off excess grout, stroking diagonally to avoid pulling grout out of filled joints. Once excess grout is removed, a thin film/haze will be left. Initial cleaning of the remaining film/haze can begin approximately 20–30 minutes after grouting (wait longer at colder temperatures). Begin by mixing cleaning additive packet with 2 gallons (7.6 l) of clean water in a clean bucket to make cleaning solution. Dip a clean sponge into the bucket and then wring out cleaning solution until sponge is damp. Using a circular motion, lightly scrub grouted surfaces with the damp sponge to dissolve grout film/haze. Then drag sponge diagonally over the scrubbed surfaces to remove froth. Rinse sponge frequently and change cleaning solution at least every 50 ft2 (4.7 m2). Discard sponges as they become "gummy" with residue. Within one (1) hour of finishing first cleaning, clean the same area again following the same procedure but utilizing a clean white scrub pad and fresh cleaning solution. Rinse scrub pad frequently. Drag a clean sponge diagonally over the scrubbed surfaces to remove froth. Use each side of sponge only once before rinsing and change cleaning solution at least every 50 ft2 (4.7 m2). Allow cleaned areas to dry and inspect tile/stone surface. For persistent grout film/haze (within 24 hours), repeat scrubbing procedure with undiluted white vinegar and clean pad. Rinse with clean water and allow surface to dry. Inspect grout joint for pinholes/voids and repair them with freshly mixed LATICRETE SpectraLOCK PRO Grout. Cautions: Do not use undiluted white vinegar on polished marble or limestone unless a test spot in an inconspicuous area indicates no change in finish appearance; do not use acid cleaners on epoxy grout less than 7 days old.

D. Expansion and Control Joints:

NOTE TO SPECIFIER: The chemical resistance of joint sealants for ceramic tile, mosaics, pavers, brick and stone will typically depend on:

1. Reagent composition and/or concentration;

2. Temperature;

3. Duration of exposure.

Review manufacturer’s performance data and recommendations, in the context of expected chemical exposures.

Provide control or expansion joints as located in contract drawings and in full conformity, especially in width and depth, with architectural details.

1. Substrate joints must carry through, full width, to surface of tile, brick or stone.

2. Install expansion joints in tile, brick or stone work over construction/cold joints or control joints in substrates.

3. Install expansion joints where tile, brick or stone abut restraining surfaces (such as perimeter walls, curbs, columns), changes in plane and corners.

4. Joint width and spacing depends on application – follow TCNA “Handbook for Ceramic Tile Installation” Detail "EJ-171 Expansion Joints" or consult sealant manufacturer for recommendation based on project parameters.

5. Joint width: ≥1/8" (3 mm) and ≤1" (25 mm).

6. Joint width: depth ~2:1 but joint depth must be ≥1/8" (3 mm) and ≤1/2" (12 mm).

7. Layout (field defined by joints): 1:1 length: width is optimum but must be ≤2:1. Remove all contaminants and foreign material from joint spaces/surfaces, such as dirt, dust, oil, water, frost, setting/grouting materials, sealers and old sealant/backer. Use LATICRETE Latasil 9118 Primer for underwater and permanent wet area applications, or for porous stone (e.g. limestone, sandstone etc…) installations. Install appropriate backing material (e.g. closed cell backer rod) based on expansion joint design and as specified in § 07920. Apply masking tape to face of tile, brick or stone veneer. Use caulking gun, or other applicator, to completely fill joints with sealant. Within 5–10 minutes of filling joint, ‘tool’ sealant surface to a smooth finish. Remove masking tape immediately after tooling joint. Wipe smears or excess sealant off the face of non-glazed tile, brick, stone or other absorptive surfaces immediately.

E. Adjusting: Correction of defective work for a period of one year following substantial completion, return to job and correct all defective work. Defective work includes, without limitation, tiles broken in normal abuse due to deficiencies in setting bed, loose tiles or grout, and all other defects which may develop as a result of poor workmanship.

3.5 Cleaning

Clean excess mortar/epoxy from veneer surfaces with water before they harden and as work progresses. Do not contaminate open grout/caulk joints while cleaning. Sponge and wash veneers diagonally across joints. Do not use acids for cleaning. Polish with clean dry cloth. Remove surplus materials and leave premises broom clean.

3.6 Protection

A. Protect finished installation under provisions of §01500 and §01535. Close areas to other trades and traffic until tile being installed has set firmly. Keep traffic off horizontal portland cement thick bed mortar installations for at least 72 hours at 70°F (21°C).

B. Keep floors installed with epoxy adhesive closed to traffic for 24 hrs at 70°F (21°C), and to heavy traffic for 48 hours at 70°F (21°C) unless instructed differently by manufacturer. Use kneeling boards, or equivalent, to walk/work on newly tiled floors. Cure tile work in swimming pools, fountains and other continuous immersion applications for 10 days for epoxy based grout and 14 days for latex portland cement based grout at 70°F (21°C) before flood testing or filling installation with water. Extend period of protection of tile work at lower temperatures, below 60°F (15°C), and at high relative humidity (>70% RH) due to retarded set times of mortar/adhesives. Replace or restore work of other trades damaged or soiled by work under this section.

C. Filling Pool – Maintain a differential of 10°F (5.5°C) or less between the fill water and substrate temperatures during fill and drain cycles, and fill pool with water at rate of 2' (600 mm) per 24 hrs to allow gradual exposure to water pressure, thermal and moisture differentials. Do not fill if potential thermal gradients exist (very cold source water, exterior pool exposed to several days of solar radiation, etc…).

D. Emptying Pool – empty pool water at rate of 2' (600 mm) per 24 hrs to prevent hydrostatic pressure from de-laminating tiles of leveling mortar (in pools without waterproof membrane).

Part 4 – Health and Safety

The use of personal protection such as rubber gloves, suitable dust masks, safety glasses and industrial clothing is highly recommended. Discarded packaging, product wash and waste water should be disposed of as per local, state or federal regulations.

Part 3 – Execution

3.1 Substrate Examination

A. Verify that surfaces to be covered with ceramic tile, mosaics, pavers, brick, stone, trim or waterproofing are:

1. Sound, rigid and conform to good design/engineering practices;

2. Systems, including the framing system and panels, over which tile or stone will be installed shall be in conformance with the International Residential Code (IRC) for residential applications, the International Building Code (IBC) for commercial applications, or applicable building codes. The project design should include the intended use and necessary allowances for the expected live load, concentrated load, impact load, and dead load including the weight of the finish and installation materials;

3. Clean and free of dust, dirt, oil, grease, sealers, curing compounds, laitance, efflorescence, form oil, loose plaster, paint, and scale;

4. Thin-set tile installations have a specified subsurface tolerance, for instance 1/4" in 10' (6 mm in 3 m) and 1/16" in 1' (1.5 mm in 300 mm), to conform with the ANSI specifications. Because thin-set is not intended to be used in truing or leveling the work of others, the subsurface typically should not vary by more than 1/16 " over 1' (1.5 mm over 300 mm), nor more than 1/32 " (0.8 mm) between adjoining edges where applicable (e.g. between sheets of exterior glue plywood or between adjacent concrete masonry units). Should the architect/designer require a more stringent tolerance (e.g. 1/8 " in 10' [3 mm in 3 m]), the subsurface specification must reflect that tolerance, or the tile specification must include a specific and separate requirement to bring the 1/4" (6 mm) subsurface tolerance into compliance with the 1/8 " (6 mm) tolerance desired;

5. Not leveled with gypsum or asphalt based compounds;

6. Dry as per American Society for Testing and Materials (ASTM) D4263 “Standard Test for Determining Moisture in Concrete by the Plastic Sheet Method.”

B. Concrete surfaces shall also be:

1. Cured a minimum of 28 days at 70°F (21°C), including an initial seven (7) day period of wet curing;

NOTE TO SPECIFIER: LATICRETE® latex portland cement mortars do not require a minimum cure time for concrete substrates or mortar beds;

2. Wood float finished, or better, if the installation is to be done by the thin bed method;

C. Advise General Contractor and Architect of any surface or substrate conditions requiring correction before tile work commences. Beginning of work constitutes acceptance of substrate or surface conditions.

3.2 Surface Preparation

A. Steel Surfaces

Wash steel surfaces with strong detergent to ensure that all manufacturing oils are removed; rinse completely and allow to dry.

B. Concrete Substrates

(Insert any Special Means of Preparation in addition to the surface preparation requirements listed in § 3.1;…)

C. (List other Substrates as required and means of preparation as required)

(Insert any Special Means of Preparation in addition to the surface preparation requirements listed in § 3.1;…)

NOTE TO SPECIFIER: Edit substrate and preparation section based on project specific surfaces and conditions.

3.3 Installation – Accessories

A. Waterproofing:

NOTE TO SPECIFIER: Adhesives/mastics, mortars and grouts for ceramic tile, mosaics, pavers, brick and stone are not replacements for waterproofing membranes and will not prevent water penetration into occupied or storage spaces below.

Install the waterproofing membrane in compliance with current revisions of ANSI A108.1 (2.7 Waterproofing) and ANSI A108.13. Review the installation and plan the application sequence. Pre-cut LATICRETE® Waterproofing/Anti-Fracture Fabric (if required), allowing 2" (50 mm) for overlap at ends and sides to fit the areas as required. Roll up the pieces for easy handling and placement. Shake or stir LATICRETE Hydro Ban before using.

Pre-Treat Cracks and Joints – Fill all substrate cracks, cold joints and control joints to a smooth finish using a LATICRETE latex-fortified thin-set. Alternatively, a liberal coat* of LATICRETE Hydro Ban applied with a paint brush or trowel may be used to fill in non-structural joints and cracks. Apply a liberal coat* of LATICRETE Hydro Ban approximately 8" (200 mm) wide over substrate cracks, cold joints, and control joints using a paint brush or heavy napped paint roller.

Pre-Treat Coves and Floor/Wall Intersections – Fill all substrate coves and floor/wall transitions to a smooth finish and changes in plane using a LATICRETE latex-fortified thin-set. Alternatively, a liberal coat* of LATICRETE Hydro Ban applied with a paint brush or trowel may be used to fill in cove joints and floor/wall transitions <1/8" (3 mm) in width. Apply a liberal coat* of LATICRETE Hydro Ban approximately 8" (200 mm) wide over substrate cracks, cold joints, and control joints using a paint brush or heavy napped paint roller.

Pre-Treat Drains – Drains must be of the clamping ring type, with weepers as per ASME A112.6.3. Apply a liberal coat* of LATICRETE Hydro Ban around and over the bottom half of drain clamping ring.

Install the top half of drain clamping ring.

Pre-Treat Penetrations – Allow for a minimum 1/8" (3 mm) space between drains, pipes, lights, or other penetrations and surrounding ceramic tile, stone or brick. Pack any gaps around pipes, lights or other penetrations with a LATICRETE latex-fortified thin-set. Apply a liberal coat* of LATICRETE Hydro Ban around penetration opening. Cover the first coat with a second liberal coat* of LATICRETE Hydro Ban. Bring LATICRETE Hydro Ban up to level of tile or stone. When LATICRETE Hydro Ban has dried to the touch seal with LATICRETE Latasil.

Main Application – Allow any pre-treated areas to dry to the touch. Apply a liberal coat* of LATICRETE Hydro Ban with a paint brush or heavy napped roller over substrate including pre-treated areas and allow to dry to the touch. Install another liberal coat* of LATICRETE Hydro Ban over the first coat. Let the top coat of LATICRETE Hydro Ban dry to the touch approximately 1 – 2 hours at 70°F (21°C) and 50% RH. When the top coat has dried to the touch inspect the surface for pinholes, voids, thin spots or other defects. LATICRETE Hydro Ban will dry to an olive green color when fully cured. Use additional LATICRETE Hydro Ban to seal any defects.

Movement Joints – Apply a liberal coat* of LATICRETE Hydro Ban, approximately 8" (200 mm) wide over the areas. Then embed and loop the 6" (150 mm) wide LATICRETE Waterproofing/Anti-Fracture Fabric and allow the LATICRETE Hydro Ban liquid to bleed through. Immediately apply a second coat of LATICRETE Hydro Ban.

 *  Dry coat thickness is 20 – 30 mil (0.02 – 0.03” or 0.5 – 0.8 mm); consumption per coat is approximately 0.01 gal/ft2 (approx. 0.4 m2); coverage is approximately 100 ft2/gal (approx. 2.5 m2/). LATICRETE® Waterproofing/Anti-Fracture Fabric can be used to pre-treat cracks, joints, curves, corners, drains, and penetrations with LATICRETE Hydro Ban.

Protection – Provide protection for newly installed membrane, even if covered with a thin-bed ceramic tile, stone or brick installation against exposure to rain or other water for a minimum of 2 hours at 70°F (21°C) and 50% RH. For temperatures between 45°F and 69°F (7°C to 21°C) allow a minimum 24 hour cure period.

Flood Testing – Allow membrane to cure fully before flood testing, typically a minimum 2 hours at 70°F (21°C) and 50% RH. Cold conditions will require a longer curing time. For temperatures between 50°F and 69°F (10°C to 21°C) allow a minimum 24 hour cure period prior to flood testing.

D. Thin Bed Method: At the conclusion of all surface preparation and prior to the installation of tile, measure the pH level of the substrate. Tile work will not commence until the pH has a value of 10 or less. Install latex portland cement mortar in compliance with current revisions of ANSI A108.02 (3.11), A108.1B and ANSI A108.5. Use the appropriate trowel notch size to ensure proper bedding of the tile, brick or stone selected. Work the latex portland cement mortar into good contact with the substrate and comb with notched side of trowel. Spread only as much latex portland cement mortar as can be covered while the mortar surface is still wet and tacky. When installing large format (>8" × 8"/200 mm × 200 mm) tile/stone, rib/button/lug back tiles, pavers or sheet mounted ceramics/mosaics, spread latex portland cement mortar onto the back of (i.e. ‘back-butter’) each piece/sheet in addition to trowelling latex portland cement mortar over the substrate. Beat each piece/sheet into the latex portland cement mortar with a beating block or rubber mallet to insure full bedding and flatness. Allow installation to set until firm. Clean excess latex portland cement mortar from tile or stone face and joints between pieces.

Apply grout release to face of absorptive, abrasive, non-slip or rough textured ceramic tile, pavers, bricks, stone or trim units that are not hot paraffin coated to facilitate cleaning. Cut open pouch and pour LATICRETE SpectraLOCK PRO Grout Part A Liquid into a clean mixing pail. Then open pouch and pour LATICRETE SpectraLOCK PRO Grout Part B Liquid into the mixing pail. Mix by hand or with a slow speed (<300 rpm) mixer until the two liquids are well blended. Then, while mixing, add LATICRETE SpectraLOCK PRO Grout Part C Powder and blend until uniform. Install LATICRETE SpectraLOCK PRO Grout in compliance with current revisions of ANSI A108.02 (3.13) and ANSI A108.6 (3.0 – 4.0). Spread using a sharp edged, hard rubber float and work grout into joints. Using strokes diagonal (at 45° angle) to the grout lines, pack joints full and free of voids/pits. Then hold float face at a 90° angle to grouted surface and use float edge to "squeegee" off excess grout, stroking diagonally to avoid pulling grout out of filled joints. Once excess grout is removed, a thin film/haze will be left. Initial cleaning of the remaining film/haze can begin approximately 20–30 minutes after grouting (wait longer at colder temperatures). Begin by mixing cleaning additive packet with 2 gallons (7.6 of clean water in a clean bucket to make cleaning solution. Dip a clean sponge into the bucket and then wring out cleaning solution until sponge is damp. Using a circular motion, lightly scrub grouted surfaces with the damp sponge to dissolve grout film/haze. Then drag sponge diagonally over the scrubbed surfaces to remove froth. Rinse sponge frequently and change cleaning solution at least every 50 ft2 (4.7 m2). Discard sponges as they become "gummy" with residue. Within one (1) hour of finishing first cleaning, clean the same area again following the same procedure but utilizing a clean white scrub pad and fresh cleaning solution. Rinse scrub pad frequently. Drag a clean sponge diagonally over the scrubbed surfaces to remove froth. Use each side of sponge only once before rinsing and change cleaning solution at least every 50 ft2 (4.7 m2). Allow cleaned areas to dry and inspect tile/stone surface. For persistent grout film/haze (within 24 hrs), repeat scrubbing procedure with undiluted white vinegar and clean pad. Rinse with clean water and allow surface to dry. Inspect grout joint for pinholes/voids and repair them with freshly mixed LATICRETE SpectraLOCK PRO Grout. Cautions: Do not use undiluted white vinegar on polished marble or limestone unless a test spot in an inconspicuous area indicates no change in finish appearance; do not use acid cleaners on epoxy grout less than 7 days old.

F. Expansion and Control Joints: Provide control or expansion joints as located in contract drawings and in full conformity, especially in width and depth, with architectural details.

1. Substrate joints must carry through, full width, to surface of tile, brick or stone.

2. Install expansion joints in tile, brick or stone work over construction/cold joints or control joints in substrates.

3. Install expansion joints where tile, brick or stone abut restraining surfaces (such as perimeter walls, curbs, columns), changes in plane and corners.

4. Joint width and spacing depends on application – follow TCNA “Handbook for Ceramic Tile Installation” Detail "EJ-171 Expansion Joints" or consult sealant manufacturer for recommendation based on project parameters.

5. Joint width: ≥1/8" (3 mm) and ≤1" (25 mm).

6. Joint width: depth ~2:1 but joint depth must be ≥1/8" (3 mm) and ≤1/2" (12 mm).

7. Layout (field defined by joints): 1:1 length: width is optimum but must be ≤2:1. Remove all contaminants and foreign material from joint spaces/surfaces, such as dirt, dust, oil, water, frost, setting/grouting materials, sealers and old sealant/backer. Use LATICRETE Latasil 9118 Primer for underwater and permanent wet area applications, or for porous stone (e.g. limestone, sandstone etc…) installations. Install appropriate backing material (e.g. closed cell backer rod) based on expansion joint design and as specified in § 07920. Apply masking tape to face of tile, brick or stone veneer. Use caulking gun, or other applicator, to completely fill joints with sealant. Within 5–10 minutes of filling joint, ‘tool’ sealant surface to a smooth finish. Remove masking tape immediately after tooling joint. Wipe smears or excess sealant off the face of non-glazed tile, brick, stone or other absorptive surfaces immediately.

G. Adjusting: Correction of defective work for a period of one (1) year following substantial completion, return to job and correct all defective work. Defective work includes, without limitation, tiles broken in normal abuse due to deficiencies in setting bed, loose tiles or grout, and all other defects which may develop as a result of poor workmanship.

3.5 Cleaning

Clean excess mortar/epoxy from veneer surfaces with water before they harden and as work progresses. Do not contaminate open grout/caulk joints while cleaning. Sponge and wash veneers diagonally across joints. Do not use acids for cleaning. Polish with clean dry cloth. Remove surplus materials and leave premises broom clean.

3.6 Protection

A. Protect finished installation under provisions of §01500 and §01535. Close areas to other trades and traffic until tile being installed has set firmly. Keep traffic off horizontal portland cement thick bed mortar installations for at least 72 hours at 70°F (21°C).

B. Keep floors installed with epoxy adhesive closed to traffic for 24 hrs. at 70°F (21°C), and to heavy traffic for 48 hours at 70°F (21°C) unless instructed differently by manufacturer. Use kneeling boards, or equivalent, to walk/work on newly tiled floors. Cure tile work in swimming pools, fountains and other continuous immersion applications for 10 days for epoxy based grout and 14 days for latex portland cement based grout at 70°F (21°C) before flood testing or filling installation with water. Extend period of protection of tile work at lower temperatures, below 60°F (15°C), and at high relative humidity (>70% RH) due to retarded set times of mortar/adhesives. Replace or restore work of other trades damaged or soiled by work under this section.

C. Filling Pool – Maintain a differential of 10°F (5.5°C) or less between the fill water and substrate temperatures during fill and drain cycles, and fill pool with water at rate of 2' (600 mm) per 24 hrs to allow gradual exposure to water pressure, thermal and moisture differentials. Initial alkalinity of pool water is very high from exposure to portland cement based finishes, grouts, and mortars; careful and frequent balance is required. Do not fill if potential thermal gradients exist (very cold source water, exterior pool exposed to several days of solar radiation, etc…).

D. Emptying Pool – empty pool water at rate of 2' (600 mm) per 24 hrs to prevent hydrostatic pressure from de-laminating tiles of leveling mortar (in pools without waterproof membrane).

Part 4 – Health and Safety

The use of personal protection such as rubber gloves, suitable dust masks, safety glasses and industrial clothing is highly recommended. Discarded packaging, product wash and waste water should be disposed of as per local, state or federal regulations.

Part 3 – Execution

3.1 Substrate Examination

A. Verify that surfaces to be covered with ceramic tile, mosaics, pavers, brick, stone, trim or waterproofing are:

1. Sound, rigid and conform to good design/engineering practices;

2. Systems, including the framing system and panels, over which tile or stone will be installed shall be in conformance with the International Residential Code (IRC) for residential applications, the International Building Code (IBC) for commercial applications, or applicable building codes. The project design should include the intended use and necessary allowances for the expected live load, concentrated load, impact load, and dead load including the weight of the finish and installation materials;

3. Clean and free of dust, dirt, oil, grease, sealers, curing compounds, laitance, efflorescence, form oil, loose plaster, paint, and scale;

4. Thin-set tile installations have a specified subsurface tolerance, for instance 1/4" in 10' (6 mm in 3 m) and 1/16" in 1' (1.5 mm in 300 mm), to conform with the ANSI specifications. Because thin-set is not intended to be used in truing or leveling the work of others, the subsurface typically should not vary by more than 1/16" over 1' (1.5 mm over 300 mm), nor more than 1/32" (0.8 mm) between adjoining edges where applicable (e.g. between sheets of exterior glue plywood or between adjacent concrete masonry units). Should the architect/designer require a more stringent tolerance (e.g. 1/8" in 10' [3 mm in 3 m]), the subsurface specification must reflect that tolerance, or the tile specification must include a specific and separate requirement to bring the 1/4" (6 mm) subsurface tolerance into compliance with the 1/8" (6 mm) tolerance desired;

5. Not leveled with gypsum or asphalt based compounds;

6. Dry as per American Society for Testing and Materials (ASTM) D4263 “Standard Test for Determining Moisture in Concrete by the Plastic Sheet Method.”

B. Concrete surfaces shall also be:

1. Cured a minimum of 28 days at 70°F (21°C), including an initial seven (7) day period of wet curing;

NOTE TO SPECIFIER: LATICRETE® latex portland cement mortars do not require a minimum cure time for concrete substrates or mortar beds;

2. Wood float finished, or better, if the installation is to be done by the thin bed method;

C. Advise General Contractor and Architect of any surface or substrate conditions requiring correction before tile work commences. Beginning of work constitutes acceptance of substrate or surface conditions.

3.2 Surface Preparation

A. Fiberglass Surfaces

Wash fiberglass surfaces with strong detergent to ensure that all potential bond breaking materials are removed; rinse completely and allow to dry. Scuff the fiberglass surface slightly with medium sandpaper and clean the surface thoroughly. Allow to dry.

B. Concrete Substrates

(Insert any Special Means of Preparation – In addition to the surface preparation requirements listed above; …)

C. (List other Substrates as required and means of preparation as required)

(Insert any Special Means of Preparation – In addition to the surface preparation requirements listed above; …)

3.3 Installation – Accessories

A. Waterproofing:

NOTE TO SPECIFIER: Adhesives/mastics, mortars and grouts for ceramic tile, mosaics, pavers, brick and stone are not replacements for waterproofing membranes and will not prevent water penetration into occupied or storage spaces below.

Install the waterproofing membrane in compliance with current revisions of ANSI A108.01 (2.7 Waterproofing) and ANSI A108.13. Review the installation and plan the application sequence. Main application: apply product to steel substrate using 3/16" × 5/32" v-notch trowel. Allow the trowel to gauge the appropriate amount of material onto the surface using the v-notch side. Once material is applied, use the flat side of the trowel to “knock down” or flatten all ridges to produce a smooth, flat surface. Be sure to look for any “pinholes” or areas not covered by the material. If any voids appear, cover same or next day with LATAPOXY® Waterproof Flashing Mortar. Make sure all 90° angles at coves and corners are properly filled.

Drain and pipe penetrations: Make sure that pipes and drains are free from rust, oil, dirt, and any other contaminants that might prevent adequate bonding. For PVC penetrations, scarify pipe with sandpaper where membrane will be applied. Ensure that pipes and drains are securely fastened, stable, rigid, and do not allow movement. Pack all voids around pipes or penetrations with closed cell backer rod in appropriate manner. Apply LATAPOXY Waterproof Flashing Mortar directly to the pipe penetration, extending 3 inches above point of installation. No fabric or sealant is required. The membrane will bond directly to the pipe. Ensure that proper thickness of 1mm (40mil) is achieved. For metal drains, flash LATAPOXY Waterproof Flashing Mortar directly over metal flange of drain – do not cover the weep holes. A two-part clamping ring style drain should be used.

3.4 Installation – Tile, Brick and Stone

A. General: Install in accordance with current versions of American National Standards Institute, Inc. (ANSI) “A108 American National Standard Specifications for Installation of Ceramic Tile” and TCNA “Handbook for Ceramic Tile Installation.” Cut and fit ceramic tile, brick or stone neatly around corners, fittings, and obstructions. Perimeter pieces to be minimum half tile, brick or stone. Chipped, cracked, split pieces and edges are not acceptable. Make joints even, straight, plumb and of uniform width to tolerance +/- 1/16" over 8' (1.5 mm in 2.4 m). Install divider strips at junction of flooring and dissimilar materials.

B. Thin Bed Method: Install epoxy adhesive in compliance with current revisions of ANSI A108.02 (3.11) and ANSI A108.6. Use the appropriate trowel notch size to ensure proper bedding of the tile or stone selected. Work the epoxy adhesive into good contact with the substrate and comb with notched side of trowel. Spread only as much epoxy adhesive as can be covered while the adhesive surface is still wet and tacky. When installing large format (>8" × 8"/200 mm × 200 mm) tile/stone, rib/button/lug back tiles, pavers or sheet mounted ceramics/mosaics, spread epoxy adhesive onto the back of (i.e. ‘back-butter’) each piece/sheet in addition to trowelling epoxy adhesive over the substrate. Beat each piece/sheet into the epoxy adhesive with a beating block or rubber mallet to insure full bedding and flatness. Allow installation to set until firm. Clean excess epoxy adhesive from tile or stone face and joints between pieces.

C. Grouting or Pointing:

NOTE TO SPECIFIER: Select one of following and specify color for each type/color of ceramic tile, mosaic, paver, trim unit:

1. Chemical Resistant, Water Cleanable Tile-Grouting Epoxy (ANSI A118.3): Follow manufacturer’s recommendations for minimum cure time prior to grouting. Store liquid components of LATICRETE® SpectraLOCK® PRO Grout* for 24 hours at 70–80°F (21–27°C) prior to use to facilitate mixing and application. Substrate temperature must be 40–95°F (4–35°C). Verify joints are free of dirt, debris or grout spacers. Sponge or wipe dust/dirt off tile faces and remove water standing in joints. Apply grout release to face of absorptive, abrasive, non-slip or rough textured ceramic tile, pavers, bricks, stone or trim units that are not hot paraffin coated to facilitate cleaning. Cut open pouch and pour LATICRETE SpectraLOCK PRO Grout Part A Liquid into a clean mixing pail. Then open pouch and pour LATICRETE SpectraLOCK PRO Grout Part B Liquid into the mixing pail. Mix by hand or with a slow speed (<300 rpm) mixer until the two liquids are well blended. Then, while mixing, add LATICRETE SpectraLOCK PRO Grout Part C Powder and blend until uniform.
