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.

We had three projects we used Flexseal on: 1. to patch small holes in a dog pool. 2. to patch a leak under our hot tub. 3. to patch a spot on the roof. Flexseal did NOT work one iota for any of these projects! Didn't even slow the leaks down. We used the tape and the spray. It didn't matter. I wish I could get my money back!

I use Flex Seal liquid for my basement a bunch of garbage doesn't work I wasted my money

Tried TWICE! Both times product had never been opened but was hard as a rock. Expensive stuff was worthless. Shameful - FlexCrap and Lowe’s in Germantown Tn

I use flex seal as instructed. Clean dry surface. Application time between coats. Proper cure time. I used flex seal on my filter basket in my hot tub. Waited a week to make sure it was cured completely. Have you used my hot tub a week now and the flex seal has turned into a soft liquid garbage! My hot tub did not leak at first but now it does again! Thank you Phil Swift! You didn't make a boat out of the damn stuff and leave it in the dark for overnight. Very misleading! Phil

Didn't know you can't paint over this until after I applied to cracks on my outside stucco walls. Had to use a rotary steel brush to remove it's so I could paint. Wasted money and not for use in areas that you have to paint over it

Well just bought a gallon $111.00 of liquid Flex seal to seal my cellar cinder block wall. It sucks as most of what I used ended up on my floor. Now I can't paint over it with concrete water proof paint. Thanks Flex seal.

The FLEX SEAL LIQUID ONLY COME IN THREE COLORS AND CANNOT BE PAITED OVER ONCE APPLIED - I is a total waste of money and costly !!
