Damtite Acrylic Concrete Bonding Additive Liquid 1 Gal.

An additive (in place of water) to Damtite Powder Waterproofer, thin-set cements, grouts and packaged concrete mixes. Improves the adhesion and strength of the coating onto non-porous (poured concrete, tile, sandstone) or previously-coated surfaces. Can also be applied directly to the wall as a primer. Covers 200 to 300 Sq. Ft. per gallon. Bonds new masonry materials to old. Will assure adhesion of the Damtite powder coatings to previously painted surfaces, floors, and nonporous surfaces. Prevents separations and cracking; increases cohesion, tensile, compressive and flexural strength. Will not yellow or discolor coating. For use with cement or plaster-based mixes on both exterior/interior, above/below grade projects.
