SPECIFICATION				KERAFLOR
Dry-Set Mortar for Low Absorption Ceramic Floor Tile

**************************************************************************************
DESCRIPTION: A dry mix of Portland cement, inert fillers, selected aggregates and chemicals, specially formulated for dry-set mortar installations of vitreous (low absorption) ceramic floor tiles, quarry tiles, and pavers over interior concrete or cement floors (see technical data sheet for additional information.)

Specify over properly prepared concrete, cement mortars or leveling coats, and cementitious backer units.

Specify for economical setting of vitreous floor tiles, quarry tiles and pavers having a relative water absorption factor of less than 6%.

Specify for interior concrete floors when mixed with water only.  For exterior applications, specify KERAFLOR with undiluted KERAPLY or PLANICRETE 50 (see data sheet for details).

Specify for setting vitreous floor tiles over concrete when mixed with water.  For setting non-vitreous (high absorption) floor tiles over concrete, specify KERAFLOR with KERAPLY or PLANICRETE 50 instead of water. (See data sheets for details.)

When specifying for installations over exterior grade plywood (interior dry areas – floors and countertops only) or over existing ceramic tiles, specify KERAFLOR with KERAPLY polymer additive. (See data sheets for details.)

DO NOT specify for the installation of Rosso Levanto and Negro Marquina marble or green marble or granite or their agglomerates.  Specify PLANICRETE W or KERAPOXY.  For all other marble types specify KERALASTIC system or GRANI/RAPID.  For setting light colored marble, specify KERALASTIC with White KERABOND.

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

When specifying KERAFLOR in the Tile Selection selected – ceramic floor tile, quarry, paver tile, 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.

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

MORTAR MATERIALS

DRY-SET MORTAR: KERAFLOR dry-set mortar, as manufactured by MAPEI CORPORATION, ANSI A118.1.   Designed specifically for ceramic floor, quarry, and paver tile installations.

**************************************************************************************
When specifying KERAFLOR in performance specification, Call MAPEI CORPORATION’s Technical Service Department toll-free number for assistance with product characteristics.

Specify KERAPLY or PLANICRETE 50 latex additive with KERAFLOR when specifying LATEX-PORTLAND CEMENT MORTAR, ANSI A118.4 (see respective specification sheets).

When specifying GROUT MATERIALS refer to respective suggested grout specification – ULTRA/COLOR sanded polymer-modified cementitious grout or KER 200 sanded polymer modified Portland cement tile grout or KER 800 unsanded polymer-modified Portland cement tile grout (ANSI A118.6) or KERAPOXY 100% solids epoxy grout (ANSI A118.3).  Grout tiles according to grout instructions and ANSI A108.10 or A108.6 specifications.
**************************************************************************************

MIXES

Proportion and mix factory-prepared mortar in accordance with 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 tilework and conditions under which tile will be installed.  Do not proceed with tilework until surfaces and conditions comply with requirements indicated in referenced tile installation standards 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.)
**************************************************************************************

[Floor Tile: Install in accordance with TCA method
[F101], [F102], [F103], [F111], [F112], [F113], [F114], 
[F115], [F121], [F141], [F144].]

Install expansion and control joints in accordance with TCA method EJ171.

Grout joints shall be clean and free from standing water, dust and foreign substances.

Tile surfaces shall be clean and dry.

PROTECTION

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 floors in unavoidable.

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.
