Flex SealReviews 220

Purchased flex seal mini for my pool and to begin with the patch didn't stick. I then opened the glue to try to use it and it was hard and wouldn't come out. Emailed the company and sent them pictures. After a few emails of discussing the issue he finally said he couldn't help me I had to take it back to the store. I work 12 hours a day and don't have time for this and why couldn't he just sent me a coupon or a replacement. I sent him pictures of the packaging and the product. Just don't think they wanted to correct the wrong and was expecting me to just go away. The person I was communicating with was named Stephen. Thanks for all the help ( yes that was sarcastic)

This flex seal paste is pure junk. Opened the can and it was hard as a rock to the bottom of the can. Wasted $29.00 will never by another. Flex seal product again...

We bought 8 spray cans of Flex Seal to coat the seams and bottom of our above ground swimming pool to stop a leak and prevent new ones. We coated it several times waiting a day between to let the first coat cure. After two weeks it was still tacky but other people told us that was normal... we filled the pool and turned the kids loose. Now we get to throw out the 2000 dollar pool because every time the kids get our their feet are coated in Flex Seal. The carpet from the back door to the bathroom was also ruined before we figured out what what mess was and we cannot get the Flex seal out of it. Also took me 2 hours to scrub the crap off my shower floor because it transfers so easily from the bottom of their feet to absolutely any other surface while somehow still being decidedly difficult to fully remove from their feet. The pool still leaks. Complete waste of money on a product that is going to wind up costing us thousands more in clean up and repair.

I put the flex Seal tape on my leaky hose. It didn't work at all I just found went to the end of the tape and started leaking out of the tape. Plus every other experience I've had with the spray as well doesn't work at all. This product is crap!

I purchased a 3lb. Tub of flex seal from lowes 2 days ago. When I opened the tub, the top and sides were set up. There was only a small space in the middle to get any material out, and it was partially set up. The crack I sealed was a metal roof over a carport, it looked terrible due to the flex seal partially set up. The tub was only 3/4 filled. Thirty dollars wasted.

Wasted my hard earned money on a product that would take gallons and gallons and gallons in spray form to do a very small amount this product didn't even fill 3/16 inch holes. Don't waste your time and money folks! Great sales pitch for us suckers used a $15 can on this small project and multiple coats with proper time to dry so I don't wanna hear it! Congratulations on yet taking someone else's money with a misleading sales pitch.

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.

Tried to fix a leak in a irragation system and gutter, on the way to lowes to find something else that works

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.

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.

Sealed a galvanized cooler interior with the paste which didn't work, then sprayed entire can in interior. Still leaks.

Recently I purchased a 4oz. Tube of flex glue from a super Walmart. When I went to use this glue the following day I found it to be dried in the tube, impossible to squeeze out and totally unusable. I checked the package and the tube. Both seemed to be completely I damaged meaning no reason for air to get in and dry out the glue. If this product has a "shelf life" than there should be a "use by date" on the package. Waste of money.

If this product was 1% effective as their commercials...
Doesn't work for crap. Tried it on an RV, instead of turning a flexible cocking, turned into hard and impossible to work with crap.

HEY FLEX SEAL why do you have so many shades of grey?

We have 3 differant shades of Flex Seal Liquid grey in our basement now and we paid you almost a 100.00 a gallon here we are 29 gallons later with 3 shades of grey in our basement on our floor and walls - WHY? - can't you make one shade of grey? WOW
RESPOND PLEASE I have all of my reciepts

We live on the lower half of a hill with a creek in the front of our house. We used flex seal spray on the outside and inside of the baseboards around our house. Flex seal kept water from entering into our house lastnight when there were flash flood warning and raining really bad. This was the 1st out of 4 times our house finally did not flood inside. Amazing stuff yall. Recommend to my mother in law for her to use in her down stairs area where water gets in as well.

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.

Initially to use on a crack in my RV roof. Before I could do that I had a drip in my grey water tank.
So I opened the tub and slogged on a good amount of paste. It NEVER stopped the drip.
So I emailed the company and they sent a for that wanted time, date, temperature, before and after pictures,
A video and copies of the receipt. I wrote them back and told them this was BS. They then responded
That they could send me a refund if I sent pictures of the tub and the receipt.

Today I opened the tub to fix the crack and the product was rock hard. I had replaced their plastic insert and seal the tub tight.

FTC needs to shut these jerks down. Anyone want to join me in a lawsuit.?
