Flex Tape, MAX, Original Thick Flexible Rubberized Waterproof Tape - Seal and Patch Leaks, Works Underwater, Indoor Outdoor - Home RV Roof and Pool Repairs, Black, 4 in x 25 ft, Pack of 1

Blew a hole in the side of my above ground pool... So far it's holding good... We will see when Summer rolls around.

It costs a pretty penny however it really works. We used it to fix a hole in a water container, no leaks n it's been a couple of years. Great product. It does what it says it will do.

Bought it to do repairs to our pool cover. Just what I needed.

This is by far the best tape I’ve ever came across. I use it sparingly for anything that needs secured because it is expensive. What I didn’t like was, I’ve ordered from the same person 2 or 3 times with no problem except for the last time. My order of the 4’x25’ roll was opened and not a full roll. Maybe because he regretted selling it as cheap as he advertised. That wasn’t my fault, I was the purchaser looking for a good price. I kept the opened roll anyway and took the loss because I like the tape that well.

I own a studio with a Rain Room so needed strong tape for the Marley flooring. This is the only tape that’s durable enough to withstand all the water. And there’s a ton of people dancing in heels on the floor. It’s held up for a year!
