Easy to Use and Effective
I got Flex Seal to seal up an exterior light fixture that had a support element that developed a crack. I wanted to keep water out of the fixture.
Flex Seal sprays on in a reasonably controlled pattern - when holding the can about 8 - 10 inches from the target, it will generate a spray pattern about two inches wide, with minimal overspray - so it is easy to control whe...

Didn't work for me
I was hoping that the black Flex Seal would be just the thing I needed to fix the sole of my work boots. I have seen this advertised before being using on boats etc so I thought it might work at well on something much smaller. I followed the directions and sprayed it on to see how it did and within 2 days the stuff had cracked and was easily peeled off. Maybe it would w...

It works but doesn’t I need to use it for a cut in my gutters and I covered the whole thing but it still leaked and I put like 15 coats of it and then I did it again and still did not work

This stuff works for the right job
This product worked well for me for a variety of uses. I was able to seal up a leaky jon boat as well as a large plastic pond tub. It can be used on most any surface and does a good job of sealing things up in a pinch.

Really good sealant
We have a inflatable pool that came with some pretty lousy repair tape. I tried to repair it, but no dice. I thought to myself..self.. I can use the flex seal!
And man, it looks strange, but it is holding up quite well.
I have not had the occasion to use this on any hardware or piping in the house as of yet, but I think it will do the trick just fine.

Amazing!
This is a "tool" that you need to make sure you have in your car. I can not say enough things about this. When I was driving, I noticed that my tire was a little flat. Thought nothing of it and went to a gas station to fill it up. NOPE! Not the problem. There was a small leak in the tire and I am so glad I had this stuff in the car. It fixed it up in no item. Really eas...

Wow!
I have had this product for several months and finally got to use it.
I sprung a leak in a PVC pipe related to the swimming pool.
Low and behold this stuff worked like a charm. You often wonder about heavily advertised products but this really worked for me!

Inexpensive and works well
After seeing several videos about this products effectiveness, I decided to give it a try on a few items. I had a tent, a watering can, and a grill cover that all had developed leaks. I followed the instructions, sometimes built up extra coats, and gave a little extra drying time. All three of the repairs worked well and continue to function. The watering can was the be...

As advertised
I’ve seen the commercials on TV and was skeptical. I used it on the inside of my gutter that was leaking, and it stopped the water leak! I haven’t used it anywhere else yet but I’m sure it will get the job done.

Excellent Sealer
After a hurricane, I had a few shingles that blew off the shed roof. Water was dripping inside so I sprayed the Flex Seal as a temporary fix to see if it would slow down. The leak stopped totally. As a precaution I also sprayed on the plywood panel on the inside of the shed and I haven't had any more leaks since using this product. I highly recommend Flex Seal for leaks...

Worked Good
I tried this on my gutters and was surprised how well it worked. I was hoping it was seal the seams where they meet and it worked like a charm. It was easy to apply and there was no mess. It dried quickly too. I also used this around my mother in laws leaking skylight in her double wide. I applied 3 coats and waiting about an hour between coats and she's not had any iss...

Leak was fixed
I've used this on a few different projects since receiving it. Worked amazing at sealing a crack that I had in my favorite outdoor birdbath. It was a little messy to use but definitely did the trick. I'm very happy with the outcome on all the projects I've used this for.

Works As Advertised
I had a gutter downspout that came through an upper level deck then turned and ran horizontal under the deck and it was leaking at a connection and dripping on the deck below. I used flex seal to spray the connection and the leak has stopped. Time will tell how long it lasts.

I used this product first to seal on a water leakage. it was great and the leakage stopeed. It has to dry a bit to start working. Next time I sprayed it on my plants pot to cover the crack. the plant container was black so this worked like charm. I did not have to color the container with the color. The product is great and works like a charm. I still have to use it on ...

Yes, please
I love this Flex Seal spray. I used on some trees in my front yard after a fresh cut. Seals it up with no random sprouts coming up after I do my annual trimming. Definitely purchasing more for next year. Thanks!
