Rated 3.6 out of 5★áby 48reviewers.
Rated 1 out of 5★áby Do NOT buy this! Whatever you do don't put this on your roof. I applied it and it worked great, then the heat of summer came and it was horrible! It cracked and shrunk making the problem WAY worse. Please learn from my mistake, costed me more money to fix and caused a worse problem. 01/02/2013
Rated 4 out of 5★áby ez to use but can be messy (do not get it on your skin -- impossible to remove) 09/19/2012
Rated 1 out of 5★áby Wouldn't buy it again. Being a senior...getting a ladder out to get up to my gutters was not easy....sprayed as instructed...waited an hour...put a second coat on....and the rain came and the gutter still leaked....enough said. 04/23/2013
Rated 5 out of 5★áby This product works This helped us secure a leaky pipe 01/09/2014
Rated 1 out of 5★áby My leak was a small leak on a horizontal pipe. It didnt stop the leak after several applications, we used the whole can, let each application dry before applying the next, did not stop the leak 10/11/2012
Rated 5 out of 5★áby Great Stuff Paid a roofing contractor to find and fix a leak around the fireplace chimney. He came back 4 times, rebuilt, reshingled, and still didn't fix the problem. I took this spray up on the roof, sprayed where the chimney meets the roof and haven't had a problem since. Could have saved myself hundreds of dollars if I had tried this first. 01/29/2013
Rated 5 out of 5★áby I use it on my asphalt driveway and it works great I use it on my asphalt driveway and it works great to cover and seal bad spots and tire tracks that have lifted up my coating 02/26/2014
Rated 5 out of 5★áby great stuff I was having all kind of problems in my basement! Finally got the water stopped from leaking, next step was to keep it from going into closet or other areas. I sprayed the product to seal around baseboards, and adjoining walls. So far so good. I won't really know it it's going to hold until more water starts to leak, which I hope doesn't leak anymore. 08/05/2012
