INSTALLATION:            Ceramic, Mosaic, Quarry, Paver, Slate, Marble and Granite

SPECIFICATION				             KERALASTIC
Flexible Polymer-Modified Portland Cement Mortar System

**************************************************************************************
DESCRIPTION: A unique polymer additive designed to be used with KERABOND dry-set mortar for increased bond strength improved vibration and impact resistance and to provide freeze/thaw resistance.  The KERALASTIC/KERABOND system is ideal for difficult-to-bond natural stone, large porcelain, and glass-bodied tiles.

Specify for interior and exterior installation of ceramic tile and natural stone over most approved substrates on floors, walls, and ceilings.

Specify for all traditional substrates as well as over existing cutback adhesive, vinyl asbestos tiles (residential and light commercial applications), and exterior grade plywood (interior residential floors and countertops in dry areas only).

Specify for setting impervious and vitreous ceramic tiles and most “difficult-to-bond” tile, such as porcelain, glass mosaic, monocottura, quarry, paving brick, gauged slate, polished-back marble, and granite.

Specify for all residential applications, shopping malls and plazas, commercial buildings and even industrial installations.

Specify	for high use and abuse areas such as schools, airports, prisons and public toilet rooms.

The KERALASTIC/KERABOND mortar system was not designed to be a highly chemical resistant mortar.  Specify KERAPOXY® for such applications.  (See data sheet for details.)

DO NOT specify for setting Rosso Levanto and Negro Marquina marble or green marble or green granite and their agglomerates. Specify PLANICRETE®W or KERAPOXY®.  When specifying light colored and translucent marble, and their agglomerated, specify White GRANI/RAPID or White KERAQUICK M.  (See data sheets for details.)

DO NOT specify over particle board, masonite, chipboard, Lauan, gypsum floor patching compounds, metal or similar dimensionally unstable materials.

When specifying KERALASTIC 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 in original containers with seals unbroken and labels intact until time of use.  Prevent damage or contamination to materials by water, freezing, foreign matter or other causes.

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.

PROTECTION

**************************************************************************************
Select appropriate statements for installation - floor, wall or both.  Delete non-applicable statements.
**************************************************************************************

[Protect floor from general traffic for at least 71 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.
