A line of masonry waterproofing paints and sealers sold for basement walls and floors.
DRYLOK is a well-known line of masonry waterproofing paints and sealers made by United Gilsonite Laboratories, sold through home improvement stores for basement walls and floors. Homeowners often try these products first because they are available and easy to apply. Used on a clean, dry, sound masonry wall with only dampness, a coating can be a reasonable step. On a wall with active leaks or pressure, drainage usually matters more, and our coatings pages explain the difference in Nashville basements.
We are an independent waterproofing company and are not affiliated with DRYLOK or its maker. The official site explains products, preparation and application, and we encourage you to read the instructions closely. If you would like a hand deciding whether a coating fits your wall, we are glad to take a look and tell you what we see.
