Rated 4.4 out of 5 by 10 reviewers.
Rated 5.0 out of 5.0 by Interesting stuff Basement wall had a pronounced crack that leaked despite a cement patch. Slathered on two coats of Drylok Extreme and the problem is gone. The Extreme is much runnier than the regular flavor and goes on well with a roller; the regular stuff is like vanilla frosting and seems to require a brush to apply. Both seem to do the job; the basement is dry, I did it all myself and I'm happy. August 28, 2013

Rated 5.0 out of 5.0 by Great stuff Great product. Works as advertised seals walls to stop water intrusion. Not sure I would frame over a wall that was leaking but it as stopped our leaks until we can dig out an repair the foundation. December 31, 2013
Rated 5.0 out of 5.0 by WORKS!!! My house is 89 yrs old. When we used this 29 yrs ago it worked great. Just getting around to using it again, it does wear away after many years. Keeps water out and looks bright and clean. Does the job! September 3, 2013
