The answer to your waterproofing problems is clear. If water is leaking through existing masonry or you need to protect new construction, Drylok Waterproofer is guaranteed to stop water to 4 PSI. It is the first clear (non-pigmented), abrasion-resistant, high-gloss waterproof coating approved for floor and wall applications. Unlike ordinary paint that simply adheres to a surface and can be forced off by incoming water pressure, DRYLOK® Clear Masonry Waterproofer actually penetrates the pores in that surface, bonding to the masonry and creating an impenetrable barrier. You can waterproof interior, exterior, above or below grade walls. DRYLOK® Clear Masonry Waterproofer is also perfect for floors, basements, retaining walls, decorative brick and stone facades, and more.
