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

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.

I used this to re-seal my outdoor fountain, after ~12 years. It is really thick stuff and it took more than I expected, but it seems to be working really well after more than a month. No leaks and really happy with how it turned out. Warning: Your brushes/rollers will not survive, so plan accordingly to dispose after each use. It’s too think to wash out.

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

Flex Seal is amazing and easy to apply. I needed to waterproof my fishing boat wooden seats that were the old school of paint on them and they needed some tinder loving care to get them back to a good state. I sanded the wood seats to get a good surface first, then applied the Flex Seal. OMG after a first coat I was amazed how well it adhered to the old plywood seats! Heads up though, do the prep work first, then apply the Flex seal with a good brush with even strokes in one direction. Allow it to be done in warm clear weather as it will take awhile to fully cure. I let it dry for a full week. Amazing finish in the final result. It is waterproof now too! Love it. I used the light gray.

Works well

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.

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

Muy práctico, pude sellar el espacio entre una lámina de policarbonato y cemento por donde se infiltraba el agua. Muy buena compra.
