  1. Redwood Johnson

    I rented a blow up water slide for a birthday party- for college age kids. I noticed a gap in the slide where two pieces came together. The kids said it was a risk of injury. I took Flex Tape and taped the two together and made it a smooth surface. The slide was very wet. It was a hot day. The tape went down easy in the water and it never came loose all day long.

    Have used the Flexseal tape and Flexseal paint….all really works. Repainted all the trim around the house windows 2 years ago and none have started to peel yet. Just used some of the black tape on a broken horse watering tank and the leaks are stopped. Yes, I’ll have to rebuy another tank, but this Flexseal “fix” will work for quite some time.

    Used it to stop water from coming into my basement!!

  4. Johnnie Martin

    I used on my high sierra backpack/22″ luggage. I used it to reinforce the needed areas on the backpack/luggage. I figured that if I needed the tape I could take it off and repair wherever needed.

    I would recommend buying the flex tape & Sealant, I used both of them they work great I patched 2 holes in the cover for the deck furniture with the flex tape and it kept the furniture dry also I used the sealant on a tray for our bacon machine and you can’t tell it had a crack.

    This did not work for a tiny, tiny pinhole in a copper pipe. As a matter of fact it made it worse.

  7. Athruz

    Tons of uses, hold up great. Just make sure you cut and test fit the piece before removing the backing that exposes the adhesive part. Very hard to reposition. Get in on right the first time, and it will work great.

    The tape failed to stop a minor leak. When you placed the tape on the side where the leak occurred it did not seal it. It’s a waste of time and money.
