Drylok 20913 1gal Floor & Wall Clear Masonry Waterproofer-1PK LANC-327676

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 Clear Masonry Waterproofer actually penetrates the pores in that surface, bonding to the masonry and creating an impenetrable barrier.
