Mapei Mapelastic Cementitious Waterproofing (Part A) - 50 lbs

Flexible, Cementitious Membrane for Waterproofing and Protecting Concrete and Masonry

Mapelastic is a two-component cementitious membrane that waterproofs concrete and masonry. It also offers protection against chemical attack from de-icing salts, sulfates, 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.
• Excellent protection against water and aggressive chemicals
• Outstanding bond to horizontal and vertical concrete, masonry and ceramic surfaces
• Available in silver (light gray) and white
• Remains highly flexible under all environmental conditions
• Suitable for irrigation canals, spillways and dams, as well as for balconies, suspended walkways and patios
• 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.
