Is this the right product?
Use it for: Pre-blended, polymer-modified thick-bed and render mortar that needs only water, no latex additive. Bonded or unbonded mud beds, scratch and render coats on walls, and concrete patches from 1/4" to 2" (6 mm to 5 cm). Floors and walls, inside or out, in homes and commercial buildings, wet or dry areas, including getting pools and fountains ready for tile. It can be pumped. Goes over concrete (cured 28 days), block, brick, mortar beds, dampened cement backer board, properly designed wood-frame floors, well-bonded cement plaster, shotcrete and pool plaster; exterior-grade plywood on dry indoor floors in homes and light commercial; and, primed with ECO Prim Grip, existing tile, cement terrazzo, quarry tile and pavers in dry indoor areas. Foot traffic after 16 hours. Meets ANSI A108.1A, with an Extra Heavy service rating (ASTM C627).
Not for: Bonding straight to concrete without prep: the surface must be porous, profiled to CSP 3 to 5, and primed with a slurry bond coat of Mapei polymer-modified thinset that meets ANSI A118.4. Wood-frame floors that don't meet building code for a mortar bed and tile. Not over standing water, wet surfaces or anything containing asbestos. Scratch coats no more than 3/8" (10 mm) and render coats no more than 5/8" (16 mm) per lift. Install between 7°C and 35°C and keep it there for 72 hours; keep water immersion off for 7 days.
Use instead: A plain sand and cement mud bed: 4 to 1 Mud Bed Mix. Rapid-setting shower pre-slopes and floor ramps: Planislope RS.
