Rubber Sealant Coating, Waterproof, Gray, 128 oz | Stops leaks fast, brush, roll, dip or pour on, UV resistant, prevents rust, corrosion, roof, basement, RV, gutters, masonry

Expensive but very effective. Is as advertised and seen on t v. I was skeptical but other than it being kind of a one time use due to it drying out. It was great. Just make sure you use it all.

It really works! It’s incredible! Highly recommend for water leakage! Not for plumbing!

I used this on a steel trash can that I store bird seed in. The top had a gash in it and no matter what I did, water would get in and ruin the seed. I hated to throw it away since that was the only problem. A can of this, and the problem was solved. It's a little spendy for the amount you get which is why I removed 1 star. But there's no question it works good. My only other gripe is that it takes a long time to set up and dry. So if you can keep your project level and dry for 24 hours, that will go a long way to helping it cure. I just used a disposable paint brush to apply it and I kept the now hard brush for future applications. It's fairly durable depending on what you're trying to accomplish. I tried using it on the feet of my deck chairs hoping it would save wear and tear on my deck? Not a good idea, it just fell off after a couple of uses. But for sealing, this is a good product.

After my very "professional" amateur water heater installation, Flex Seal came to the rescue! 😂 It helped seal up those little spots that made me question my plumbing skills. Easy to apply, waterproof, and gives great peace of mind. It may not make me a master plumber, but it definitely helped keep my DIY project from becoming a swimming pool!

I use it to seal cracks in asphalt and between asphalt and concrete around my house. Also on my roof and around the chimney. I have used it to rust proof areas on vehicles. This stuff is the best i have ever found to do these jobs! I only wish they made it in a squeeze applicator. I will definitely purchase again.

It did the job it needed to

It worked great! Sealed my patio cover just fine. I bought an extra gallon just in case it was not quite enough. Didn’t need it had about a quart left for any touch ups we needed. Went to return the unopened extra gallon and found there is a no return policy.

It worked as a short term fix. Did not work for full summer season. This is good if you want a short term fix as saving for the proper all inclusive fix. Others have had better results, which may be my error. It did not take long to dry. It was easy to install. Was okay value but I viewed as a temporary fix.

Muito bom

This product has fixed the leak in my fibreglass swimming pool at the moment. The ongoing test will be to see how the flexseal stands up in the long run with pool chemicals, in particular chlorine.

works as advertised. easy to apply, little on the expensive side.

Not cheap but fixed hot tub liner brilliant stuff will definitely buy again and easy to use

liked it because it self levelled and easy to use .l dislike the time it takes to dry
