this product does not work AT ALL. Do not waste your money. it did not even seal a hair line crack on a pipe.

Ok, lets get real this product does work, but you may have to do a little extra on your part depending on what your using if for. I could not not afford to water proof my basement at the cost of 40.000 with the company I will not mention, not trying to take business away or put them in a bad light but I use Flex Seal to do my whole basement yes it was time consuming but I put a little more work into it before using Flex Seal I sanded and cement the walls first, than a week later I use the all white Flex Seal to paint over the cement I rolled it on thick the first and only time so I would have a nice thick layer and it may have taken me 2 months to finish but it looks good. I love my concrete walls and now there white and rubbery nice to the touch, its one year now and no leaks. So people before you trash a product be mindful on how you use it and the steps you take before use. This product does work!

Purchased a small tub of Flex Seal Black Paste -- When I opened, it had already solidified around the edges -- Was able to use some from the middle by penetrating with a screw driver, but within three days, even after covering the tub with lid tightly and putting in a plastic bag, it had hardened too much for use-- Could not evaluate the product since I was not able to get enough to fill my problem area.

Garbage! Wouldn't stick. Top layer dried out and hard. Flex Seal got me this time but never again!

I paid a small fortune for a 4oz tube of the glue. And when I opened it the glue was no good.

Clean and followed instructions correctly use to fix my husband car hold our carpet down put glass back together waited the correct time for it to bond together absolutely love it worth every single penny I spent on it

We used it to coat my bay window area when a new roof was put on in April 2022. In December 2022 the area leaked again and my roofer went up to look at it and it had cracks all thru where he had put the FLEX SEAL. He said it was a bear to work with and he would never use it again. I will not recommed this product to anyone.

Absolute GARBAGE!! I bought two cans of the spray rubbish with the intention of using it to spray a home made feral cat shelter so it was water proof ... yeah, right. After shaking the can for a good length of time it sprayed out in a single JET and was as thin as water - the crap went every where and was nothing like what I expected. I don't know how that idiot Phil Swift can sleep at night advertising this stuff. Total garbage, Total waste of money!!!
