7 Lb. White Powder Masonry Waterproofer

A Portland cement-based waterproofing coating for sealing protecting and decorating vertical walls constructed of concrete masonry brick or stucco. Just add the powder to water.

Unlike ready-mixed paints that can only be applied to dry surfaces it is made to be used on damp walls. Safe for coating drinking water holding tanks or cisterns birdbaths and fountains. Reduces radon gas penetration through concrete block walls.
