Drylok Matte Gray Tintable Latex Masonry Waterproof Sealer 1 gal

If water is leaking through existing masonry or you need to protect new construction, Drylok Oil Base Masonry Waterproofer is very effective in stopping water. Unlike ordinary paint that simply adheres to a surface and can be forced off by incoming water pressure, Drylok Oil Base Masonry Waterproofer actually penetrates the pores in the surface, bonding to the masonry and creating an impenetrable barrier.
