Rated 4.0 out of 5 by 9 reviewers.
Rated 5.0 out of 5.0 by Did a great job!!! Did exactly what it was supposed to do. Sealed all the cracks and water remained in the fountain. April 21, 2015
Rated 1.0 out of 5.0 by DOES NOT WORK>>>>DO NOT WASTE YOUR MONEY!! I spent $400 a few years ago on this product and 20 hours of my time. I have a block foundation and I prepped the surface with the etching solution and wire brushed any spots that needed it. I followed the directions!!! I have an entire wall that the Drylock is peeling off. I contacted the Manufacturer and they tell you that it will stop water but not Efflorescence ( they now have this on their website but when I bought the product it was not there!!!). Efflorescence is the white crystal that if left behind when water it will stop the water but once the water dries and the efflorescence appears the paint will peel off and you are out of luck and have wasted you money and time. UGL the maker does not stand by their product, when you contact them they get defensive right away. AGAIN>>>THIS STUFF IS JUNK!!! March 24, 2014
Rated 3.0 out of 5.0 by looks real nice Works Not so much , just like the other guy said . I did all the prep work , it went on nice 2 coats also spent about 20 hrs. Time & $300 -400 that be ing said I never believe u can stop hydrostatic pressure from the in side a basement foundation trapped water will always seep throe , But hey it look great ."'

Rated 4.0 out of 5.0 by Tenacious stuff This is fairly thick and sticky paint that takes a long time to brush in properly, but makes for a good finish on concrete basement walls. It will pull your arm off during application if you don't rest every so often and/or switch arms. November 2, 2014
Rated 4.0 out of 5.0 by easy to use the paint went on easy, dries fast, little smell, easy clean up. will use again March 6, 2015
Rated 5.0 out of 5.0 by Drylock Extreme is the best product for moisture control on basement walls. This product applies easily with a brush or roller. It also has a mildew retardant. January 20, 2015
Rated 4.0 out of 5.0 by great waterproofer This is a very thick solution that takes a while to apply. Once applied it keeps the water out and no mold growth as advertised. December 15, 2014
Rated 5.0 out of 5.0 by worked great for me! Applied it a year ago and my crawlspace has been dry since! October 21, 2014
