If water is leaking through existing masonry or you need to protect new construction, our proprietary formula is GUARANTEED to stop water.

Unlike ordinary paint that simply adheres to a surface and can be forced off by incoming water pressure, DRYLOK® Floor & Wall Masonry Waterproofer actually penetrates the pores in that surface, bonding to the masonry and creating an impenetrable barrier.


Waterproof interior, exterior, above or below grade walls. DRYLOK® Floor & Wall Masonry Waterproofer is also perfect for floors, basements, retaining walls, decorative brick and stone facades, and more.
