Rated 1 out of 5 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 out of 5 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 5 out of 5 by This is the product to stop moisture from the bottom up. This product will hold back moisture with up to 15 PSI from coming up through a floor. This is the real deal. March 6, 2014
