Flex Seal

Opened 3 plastic cans of Flex paste 3 months after purchase... all were solid hard. Cannot use. Called customer service... wanted pictures, provided pictures, no response. Product does not work on the roof of motorhome as they claim. Hardens and becomes brittle and cracks.

Hey people I bought the 3 lb. can and am totally satisfied! Easy to apply, easy to clean up myself and my tools. Sealed around my stove pipes which were previously leaking and it worked, it did what was described. Now we will test it over time and see if we get a leak in the future. So far your product gets ten stars!

Ive used it on everything from my roof, gutters, concrete statues, paintings, including paintings on glass tables! But if it comes in contact with sidewalk salt, i use the pet safe stuff, it strips it right off! But i sprayed our entire purgla prior to assembly and 4 yrs still going strong

Two stars because the product worked for me, but the container was apparently defective. Used product once after buying it in September 2020 for a small job using very little of the contents. I recently (March 2021) went to my workshop shelf, where all my products are stored without problems, and found the can had erupted like Mt. Vesuvius. I am happy with the product as it has held up well in the direct Arizona sun for about six months now. I'm unhappy because the small amount I used turns out to have been pretty expensive considering the can failure and the rest of the product now going in the dumpster. I hope Amazon/Flex Steel will replace the defective can... we'll see and I'll try to provide a follow up to this post.

I purchased Flex Seal paste to seal up some leaks in our basement. It works pretty well on holes that are dry at the time you seal them, but does not seal a hole with water running through it like they tell you on tv. It just dissolves into the water. Also you need to use it all as soon as you open it or it will harden and you cant use it.

Could not seal my 8" pvc irrigation pipe this morning. Tried 3 times, scuffed up the pipe as well and it does not stick under water OR UNDER ANY CIRCUMSTANCE'S as shown in the commercials. The pipe is not fixed and is still leaking. Good thing it was purchased at Walmart as they do take everything back and I will be returning this bogus product today. My duck tape works just fine under an emergency. Do not waste your money.

Cleaned and taped a small section of our patio seam that was leaking. Waited for nice weather to make sure there was no moisture. Applied three coats. When weather reached In the lowered 90s, it cracked.

I have purchased almost all the stupid products advertised by this company. DO NOT WASTE YOUR MONEY! Nothing works!Not even for 5 minutes. They have no guarantees but worse it solves no problems. Leaks still leak and the advertising is outrageous lies. Cant say enough negative remarks about this totally useless product line.No need to send pictures just water leaking all over. They should be reviewed by consumer affairs committee and shut down!

After politely explaining the urgent nature of my repair, Stephen from "customer service" replied that my order would be processed in the order received. No Apology for quoting a time they couldn't fulfil. Yeah, the 'Rona, we all know---but what I see is that they care more about getting that order than the customer or being honest, so they intentionally deliver normal shipping quotes on the website. I don't code, but I know it's pretty simple to adjust something like that.

As usual, if you see a slick widget-slinger on a TV commercial, plan on the snakeskin underbelly, in this case made of clear, white, or black rubber.

Doesn't actually do anything even after 40+ coats. The ads are definitely a lie, I damn near destroyed my gutter in the process of trying to fill a pin hole. Well... I would've if the $#*! didn't scrape off like butter. Still, now it looks eternally dirty and gross thanks to the residue.

Unfortunately I did not read the reviews I purchased the spray and the tape neither of the 2 products came even close to my expectations. I personally would have to agree with everyone else that I have read their comments this product is sub standard and junk. I used it on my wood shop roof to stop leaks I have varieties of exotic woods expensive machines to mill wood with I do custom wood working I lost approximately $4000 worth of exotic woods because of this product all so tools got wet causing rust staining wood. There is a problem in the finishing process. I think what needs to happen here, an attorney needs to get involved. A class action lawsuit should be issued at this point not only from me but everyone else.

The paste is a joke! It sets up as soon as you open. Very difficult to work with. Advertising very misleading& cost is ridiculous. Sorry, should have looked at reviews before purchased. Took back & got my money back. The store when I returned told me they have a lot of returns for this product & I see why.

I got the spray on flex seal to stop a leak in a man hole. Worked on it all summer so it would be dry. I put about 6 or 7 layers and the first rain fall, it leaked. So don't waste your money. Can you say " garbage"
Thank you. Francis

I bought two cans of the flex seal. I used both cans as directed and still had a leak. The leak was a very small one and it leaked just as bad 5 days later after 5 coats. I wish I would have stopped after the first can because I wasted 25 dollars on this terrible material. Don't waste your time or money is my suggestion.
