SPECIFICATION				KERAPLY
Acrylic Latex Dry-Set Mortar Additive for Ceramic Tiles

**************************************************************************************
DESCRIPTION: An acrylic latex dry-set mortar additive that forms high bond strengths to vitreous and non-vitreous tiles over various substrates, such as concrete and exterior grade plywood when mixed with KERABOND, KERAFLOR, KERASET, or ULTRAFLOR dry-set mortars. (See technical data sheet for additional information).

Specify over properly prepared concrete, cement mortars and leveling coats, masonry block, existing unglazed ceramic tile, paving brick, terrazzo, gypsum wallboard, cement plaster, cementitious backer units, and exterior grade plywood (dry areas, interior residential floors and countertops only).

Specify for floor and wall applications, except when specified with KERAFLOR (floors only).  (See data sheet for details.)

Specify for interior and exterior installations.

Specify for setting non-vitreous (high absorption) and vitreous (low absorption) ceramic tile mosaics, quarry, paver, slate, and granite.

Specify for applications where improved adhesion, reduced water absorption, greater bond strength, and increased shock and impact resistance is desired.

Specify with factory-prepared dry-set mortars on exterior applications to increase freeze/thaw resistance.

DO NOT specify KERAPLY on vertical surfaces with KERAFLOR.

DO NOT specify for installation of white or translucent marble.  Specify white GRANI/RAPID system (See data sheets for details).

DO NOT specify for installation of Rosso Levanto and Negro Marquina marble or green marble or granite or their agglomerates.  Specify PLANICRETE W or KERAPOXY.  (See data sheets for details.)

DO NOT specify over presswood, particleboard, masonite, chipboard, Lauan, gypsum floor patching compounds, metal or similar dimensionally unstable substrates.

When specifying KERAPLY in the Tile Selection selected - ceramic, mosaic, quarry, paver, slate, marble or granite - add appropriate articles or paragraphs under the applicable PART as indicated.

SUBMITTALS

Product Data: Submit manufacturer’s technical information and installation instructions for materials required.

QUALITY ASSURANCE

Provide tile, grout and setting materials from one source.  Additives, dry-set mortars, installation materials and grouts shall be from the same manufacturer.

DELIVERY, STORAGE AND HANDLING

Deliver and store packaged materials from one source.  Additives, dry-set mortars, installation materials and grouts shall be from the same manufacturer.

If frozen, do not stir until material has completely thawed.

Deliver and store materials on site at least 24 hours before work begins.

Provide heated and dry storage facilities on site.

PROJECT CONDITIONS

Maintain environmental conditions and protect work during and after installation to comply with referenced standards and manufacturer’s printed recommendations.

Vent temporary heaters to exterior to prevent damage to tile work from carbon dioxide build-up.

Maintain temperature at not less than 50 degrees F (10 degrees C) in tiled areas during installation and for 7 days after completion, unless higher temperatures are required by referenced installation standards or manufacturer’s printed instructions.

PART 3 EXECUTION

**************************************************************************************
Specifications for surface conditions are listed in the beginning of the specification of MAPEI’s Architectural Binder.  These specifications should be called out with the related work sections.  Delete non-applicable conditions.  (Refer to ANSI EXPLANATION AND NOTES section: AN-3 RELATED WORK SPECIFIED IN OTHER SECTIONS.)
**************************************************************************************

EXAMINATION

Examine surfaces to receive tile work and conditions under which tile will be installed.  Do not proceed with tile work until surfaces and conditions comply with requirements indicated in referenced tile installation standard and manufacturer’s printed instructions.

INSTALLATION

Install tile in accordance with manufacturer’s printed instructions and ANSI A108.5

**************************************************************************************
Select TCA method to be used and delete non-applicable methods.  (Select from latest edition of the TCA Handbook.)

PROTECTION

**************************************************************************************
Select appropriate statements for installation – floor, wall or both.  Delete non-applicable statements.
**************************************************************************************
[Protect floors from general traffic for at least 72 hours after installation.  Plywood or stepping boards may be used after 24 hours when occasional stepping on the floor is unavoidable.]

[Protect walls from impact, vibration and heavy hammering on adjacent and opposite walls for at least 14 days after installation.]

Protect from freezing and total water immersion for at least 21 days after installation.

**************************************************************************************
When dealing with cement-based products, it should be noted that temperature and humidity during and after installation of tile affect final curing time, i.e., low temperatures (60 degrees and under) and high humidity (70% and above) will delay final cure time.
