Flex Seal Anmeldelser 58

This stuff was so bad its nearly comical. I could have tied a rag around the hose and it worked as well. 1 star is too high for this. Use only if you are prepared for disappointment.

Not a good solution for fixing roof leaks.
It will eventually cease to adhere to the roof

Purchased two tins of Flex Paste to seal a minor leak in a concrete water tank. Is supposed to set even underwater, but it wouldn’t stick at all. Apparently it cannot do what it claims.

I bought this product because i found a small hole at the tip of my condom..i thought the hole was leak proof..two weeks later my girlfriend came up to me and said shes pregnate. Good one flex seal🤬 your product has given me a life time of misery..

Bought flex seal draft tape---Good concept but does not stick. Bad adhesive negates a great idea. All of the ends started curling right after application so when it gets below zero this winter I am sure that it will all be in the trash can,

Well I bought flex seal twice both times it was bad you can't seem to make a good product waste of my time to bye it again i will give your product a subzero

Not a durable fix for even minor RV roof leak.
It might of lasted a month at the most.
Don't waste your time and risk having another leak, it is not at all dependable.

Flex glue crystal clear mini. It is petroleum gel in the tube, it is not glue.

I have used FlexSeal in three different forms- spray, paste and tape. I used the spray on a basement wall that leaked water when it rained. After multiple cans at $16 per can, the wall still leaks. I used the paste on the same wall. Opened the container to find it had hardened around the edges. Wall still leaks. Used what I could on roof. Roof still leaking. $17 wasted. I used the tape on a cracked cast iron waste pipe. Stopped the leak( it was a vertical waste pipe- not under pressure) until I could get a plumber to repair it. $15 and not user friendly. Overall review- avoid this product. Overpriced and under performs.

This is the second time I have been duped by this scam company and their scam products. The first time was some 'amazing' rubber patch that was supposed to adhere underwater for a quick repair of pool liners and pond liners without having to empty and dry first. Didn't stick at all underwater.

Now this supposed caulking, which is barely water soluble, don't expect to use it like regular caulking. I don't know what this stuff is made of, but it does not clean up. If you get it on your hands it takes forever to wash it off. If you get it on a cloth, it won't come off at all. Gawd forbid you make a mistake applying it and try and fix it. I was simply trying to caulk around some windows where I had stripped the old caulking off because it was looking yellow and worn. I started to apply this supposed caulking, like I normally do, wet my finger to start to smooth it neatly into the corner and then spent an hour trying to clean this garbage off my hands, window, cloth, sink etc.

Never again will I fall for this scam company and their scam products.

Used flex seal tape between two metal roof sections. It gapped and leaked throughout the job. I had to seal the gapped areas with roof cement.

Tried to use liquid flex seal above my windshield to stop leaking rubber seal, what a disaster, used painting tape above and below the area. Product is so thin and runny, it ran down over the 2 inch tape and about 10 inches onto my windshield, never again!! What a pain trying to get it off my windshield..

I bought a can of Flex Seal spray on. I needed it for a gutter running over my Lanai that was installed and only butted up against the 2 ends. Every time it rains it has a steady flow of water running onto my Lanai. I applies 3 different spray applications and only slowed it to a steady drip. I have no confidence in it ever working. I wouldn't buy any of their products, good advertising just on positive results.

Absolute garbage. Wouldn’t even stop a drip when the main water valve for the house was shut off

Product half cured when I opened one of two containers. I reached out to them over a dozen times via their website, email, and phone and they have not responded to my requests for info on shelf life and date codes...who know if this crap works in application because it's cured before I get the chance. Big dollars for something you can't use and has no support.

I've wasted nearly half of my roll of 4" clear because the backing is impossible to remove and the tape can't conform to my plumbing with it in place. A total WASTE of MONEY!

This product is a fraud doesn't work. Had a hole in my pool. From the outside tried to cover it while it was leaking. Stickiness went away as soon as water hit the tape. This product sucks.DO NOT FALL FOR IT.

After two years I think it's time to write a review, needed to seal up a couple of skylights in my shop because of leaking, summer of 2022 thought I would try flex seal liquid, gave it 3 coats, 3 months later... leaking, gave it 3 more coats, 4 months later leaking again! Last summer went up and 4 coats, well guess what... leaking again! It's probably been coated 12 times, I've got $400.00 invested in something that doesn't work and never will! Sure it works on the bottom of a boat as long as you put 5 coats on it and keep it in the water so the sun can't get to it! I would like to know how many times Phil built his boat before it actually floated! Too bad you lost a customer.

I paid over $30 for waterproof flex seal tape to patch the waterside bounce house and it would stick to everything but what I needed it to.

Bought Liquid Flex Seal and Flex Tape to have on hand for plumbing emergencies. Discovered a leak in a water line, no problem I have Flex Seal... Applied the Flex Seal tape to a clean and dry surface first, (start with the basic), didn't seal anything, just redirected the water to the end of the the tape. Removed tape, dried area again and applied Liquid Flex Seal, allowed to sit over night. Turned water back on and AGAIN it just redirected the water to where the seal ended. May as well have been craft glue or scotch tape - WORTHLESS.

Now I have a can of liquid flex seal and a roll of flex tape but no longer trust it to have for emergency repairs.

The commericals look great, too bad they are fake.

Big waste of money, BIG waste.
