Mapei - Mapelastic Liquid Waterproofing Membrane Part B 7.56 L

Mapei waterproofing membranes — quiets footsteps and evens out the subfloor beneath your new floor.

Mapelastic is a two-component, cementitious membrane that waterproofs concrete and masonry. It also offers protection against chemical attack from de-icing salts, sulfates, chlorides and carbon dioxide. Mapelastic’s specially formulated synthetic resins generate a hardened layer that remains flexible under all environmental conditions.

The dried mortar remains waterproof up to 50 feet (positive side) of hydrostatic head pressure and resists chemical attack from de-icing salts, sulfates, chlorides and carbon dioxide. Mapelastic offers excellent protection to structures in coastal areas exposed to high humidity and salt, as well as those located in heavy industrial areas exposed to aggressive airborne chemicals and pollutants.

Mapelastic is carefully engineered to fully cover hairline and micro cracks evident in placed concrete, and to allow adequate flexibility so that cracks up to 1/32" (1 mm) may be bridged. This specific product engineering ensures that Mapelastic will not conceal structural cracks that develop in concrete structures.
