SPECIFICATION				PLANICRETE 50
Multi-Purpose Additive for Dry-Set Mortars, Leveling and Priming

**************************************************************************************DESCRIPTION: A multi-purpose latex additive for dry-set mortars and leveling coats.  This extremely stable, synthetic latex emulsion, when added to pure Portland cement, will act as a high strength bond coat to concrete.  A mixture of PLANICRETE 50 with Portland cement and sand will make cement/sand coats, thick mortars and leveling coats more freeze/thaw and impact resistant, more flexible and less water absorbent.  Roller-apply PLANICRETE 50 full strength onto dry gypsum wallboard before applying dry-set mortars or adhesives.

Specify for latex cement bond coat installations: when specifying with Portland cement, PLANICRETE 50 acts as a bonding agent to existing concrete, thereby increasing the adhesion of the setting or leveling mortar prior to setting tile.  When specifying with MAPECEM Hydraulic Binder, PLANICRETE 50 acts as a bonding agent to existing concrete.

Specify for Portland cement mortar bed or leveling coat installations (from 3/16” (5mm) to 2” (50mm) thick): when specifying with Portland cement and sand mixes, PLANICRETE 50 is ideal for exterior applications and tunnels where ceramic tile, quarry, paver and natural stone are installed.

Specify for primer/sealer application: when specifying as a primer, PLANICRETE 50 helps to strengthen plaster, gypsum wallboard and concrete surfaces prior to setting ceramic wall tiles.  Specify Planicrete 50 to be applied full strength with a roller or brush.

Specify as an additive to dry-set mortar:  may be specified as an additive to factory-prepared dry-set mortars to increase bond strength, impact strength and freeze/thaw resistance.

Specify to drastically reduce relative water absorption of mortar to approximately 5%, making the mortar more resistant to urine, mild diluted acids, and alkalines.

DO NOT  specify for patching or leveling concrete substrates requiring less than 1/2” (12 mm) correction.  For such work specify ULTR/PLAN,LEVEL/PATCH or ULTRAPLAN MB.   (See data sheets for details.)

DO NOT specify as a waterproofing system.  Specify PRP 315 Thin Load Bearing Trowel Applied Anti-fracture and Waterproofing Membrane.  (See data sheet for details.)

DO NOT specify as a strong chemical resistant mortar.  May be specified for substrate preparation and leveling, but once cured and dried, it must be covered with KERAPOXY.  (See data sheet for details).

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

When specifying PLANICRETE 50 in the Tile Section 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 tilework from carbon dioxide build-up.

Maintain temperatures 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 requires by referenced installation standards or manufacturer’s written instructions.
