Stopped the dripping

Thank you for providing the lowest price on Flex Seal. In a house I own, the sink material is connected to the entire countertop, and I'm not ready to replace it, as that would necessitate replacing the countertops as well. However, the sink is very old and has become porous, which is causing it to leak. I need to seal it to stop the leaks.

Sealed back of rug

I bought this to try to salvage a rug that i love. Its an indoor/outdoor type with a rubbery backing, originally. The upper part still looked good but underneath it was crumbling. Whenever the rug was moved, it left a pile of rubber dust. I cleaned the rug well and gave the back about three coats of Flex Seal. The rug is flexible and stays clean now.

I had a water leak issue in my home basement, and I decided to try some of this stuff. I've seen these commercials forever about how awesome it is. It does work well and compared to some other things that works better. It is kind of pricey, and I think it's a good product. Probably a great product but not the best. But certainly not the worst. And I would recommend it
