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.
