Multiset MSMW50 Thin-set Mortar 50 Pound Bag

Product Description

The MULTISET MSMW50 is an economical polymer modified thin-set mortar formulated for bonding tile to a wide range of substrates in floor, wall, and countertop installations. It bonds vitreous, semi-vitreous, and absorptive tile types including ceramic mosaic, quarry, cement, porcelain, brick, mini-brick, precast terrazzo, and natural stone. Approved substrates include concrete mortar beds, masonry, Portland cement plaster, cement backerboards, gypsum wallboard in dry areas, and existing ceramic tile. Coverage runs approximately 80 to 90 square feet per 50-pound bag when applied with a 1/4 x 1/4 x 1/4 inch square-notch trowel. Pot life is 2 hours.

This mortar is suited for residential and light commercial tile installations where a cost-effective, polymer-enhanced thin-set is required. Common applications include floor and wall tile in bathrooms, kitchens, utility rooms, and countertop surfaces. It is installed by tile setters, flooring contractors, and skilled trades workers. Do not apply over hardwood, luan plywood, particle board, parquet, cushion or sponge-back vinyl flooring, metal, fiberglass, plastic, or OSB panels.
