Prefect to have around if you need a quick fix

30 days ago
This worked great for a repair on my saltwater fish tank. It was easy to use, molded exactly where I needed it to, and made a good seal when it cured. I appreciate products like these because you never know when you’re going to need it. It’s still holding up without issues.

Awesome water tight putty

a month ago
This putty works so well. I used it under my sink on the seams for the pipes. I had a leak. We put some of this on, and no more leak. It has been a month, and no leaks, and no reapplication needed. I highly recommend.

Easy to use

Mess free and easy to use. I sealed a gap between the baseboard and the wall. It's putty, so you apply and smooth out. It's so simple. Love the Flex Seal Putty.

Easy to apply

a month ago
My hot tub developed a leak and I couldn't figure out how to stop it without doing something very invasive. FlexSeal solved that problem for me, at least temporarily, and has made it possible for us to use our tub during this summer weather. It's easy to apply and works very quickly.
