Rated 4.3 out of 5 by 9 reviewers.
Rated 5 out of 5 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 out of 5 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 out of 5 by Works awesome - coverage is more than stated I have used this product on two renovation properties that had wet basements. Keeping in mind that water diversion is the only effective way to keep the majority of water out of a basement (i.e. grade away from house, proper gutters/downspouts, french drains, etc) we use this to coat the interior walls to help prevent any moisture from coming in. One corner of the house had extreme water issues so we did waterproof the exterior of the basement, but the rest was fine using just Drylok Extreme. One thing I would say, however, is for us the coverage is way off. The 1 gallon can says 'coverage up to 100 sq ft'; likewise the 5 gallon can says 'coverage up to 500 sq ft'. For a basement that is 40' x 25' with 7' walls, i.e. 910 sq ft, 1 coat should have used 9 gallons, 2 coats 18 gallons. We purchased 4 of the 5 gallon buckets and had them tinted. We ended up only using just under 2 of the 5 gallon buckets for 2 coats. I am hoping Home Depot will take the other 2 5 gallon buckets back despite them being tinted. July 12, 2014
Rated 3 out of 5 by So Far so good I used this product on my basement walls. If your basement is damp or humid it takes DAYS not hours to dry....FYI. Spent many hours painting this on. It seems to have stopped the water ..for now. The fact some posts say it starts to peal and doesn't hold up well concerns me. Hope not, spent a lot of time and money on this project. June 28, 2014
Rated 5 out of 5 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
