Description
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® Original Masonry Waterproofer actually penetrates the pores in that surface, bonding to the masonry and creating an impenetrable barrier.
Waterproof interior, exterior, above and below grade walls and more: basements, living spaces, laundry rooms, dry storage, hobby corners, fish ponds, retaining walls, birdbaths, and more.
