Drylok White Masonry Waterproof Sealer 35 lb

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 Powdered Masonry Waterproofer - when mixed with water - actually penetrates the pores in that surface, bonding to the masonry and creating an impenetrable barrier.
