[This review was collected as part of a promotion.] Great product!! We used this to seal a spot on our roof that was leaking. It has held up great and is a quick fix for many household projects. Would definitely recommend to any homeowner.

[This review was collected as part of a promotion.] Since it’s a paste, it’s a little thick. But it works! We had a leaky pipe under the sink, we put the paste on one layer and an hour later, no more leaks. Received this product for free.

[This review was collected as part of a promotion.] I’ve seen this product so many times but never used it until now. We had a leaky and constantly moving spot from the outside wall around a spigot and I applied this around the faucet and in the space between the wall. It worked wonderfully! It sealed the space up and the faucet no longer moves and was super easy to do. Next up….craft projects!
