  • Great product, but 1/4 was dry
Style: White Tub (1 LB)
If you know/use flex seal you know its a good short term fix for leaks and such- this product is no different but the seal didn't work as some of the product had already dried up. Also 1 lb is not much, I was a little surprised by how small it was but it did the job I bought it for. Also arrived quickly ... show more

  • Stopped roof leak quick
Style: White Tub (1 LB)
Easy to use, came with 3 sizes putty knives, easy on . Cured quick and stopped the water. Will buy again.... if I need it for other places.

  • Needs a better container
Style: White Tub (1 LB)
Dries out quickly and is too thick to spread. It did work, just hard to manipulate and cover small spaces. It actually would work if it hard an airtight container.

  • Difficult
Style: White Tub (1 LB)
Upon initially opening the product, I took notice that although it did not appear to have been previously opened (the seal was tight and completely sealing the paste underneath) the outer most circumference of the paste was dried out, leaving me a small well to work with. The instructions specifically mention not to throw the seal away and to make sure it completely covers the paste and work from the center to the outside to ensure complete coverage. Did not help that it came dried out to begin with. As expensive as it is, I find that unacceptable. I worked carefully not to leave a gouge in the existing well, smoothed it out the best I could and resealed it equally as carefully when done. It has not significantly dried out any further. Will not purchase again. ... show more

Did not work well

  • Dries out
Style: White Tub (1 LB)
It worked great to seal the leak, but even though I covered it and put the lid on, next time I opened it, it was completely dried out.

  • Fixed small leak in pool instantly!
Style: White Tub (1 LB)
We've owned an above ground pool for 3 years now, and thought we might be able to get 1 more summer out of it before having to get a new one, when I noticed a very small hole/slit in the bottom of it. It's a good sized pool, and I'd have to put water in it every other day. The pool was full, so I decided to buy some of this stuff to see if it could possibly squeak by for another summer without having to waste the water or money on a new one. I'm so happy to say, it worked like a champ! I got a little bit of flex seal on the little paddle they send with it, went under water, spread it, and wallah! Fixed! It's lasted for over 3 months so far with no issues. I will say that it's difficult to get off of anything, including yourself...I used a little goof off, and scrubbed just a bit, and it wasn't too bad. It also seems that the top of the jar set up, even though I left the foil thingy in there & tightly closed it. However, it only takes a small amount, so I should be good until....Forever!? ... show more

  • Much better than regular caulk
Style: White Tub (1 LB)
The kitchen sink no longer shows dirt or mold since replacing the caulk.
