Flex Tape, Original Thick Flexible Rubberized Waterproof Tape - Seal and Patch Leaks, Works Underwater, Indoor Outdoor - Home RV Roof Plumbing and Pool Repairs, Black, 4 in x 5 ft, Pack of 1

I used this to seal some pvc that ran horizontally, this is wicked good. Got a weird leak you need to fix and don't or can't re-do it all, this will do the job. make sure you get enough, I did a wrap around my pipe taking no chances.

this stuff really works. I used it to seal a tear in a flexible, 150 gallon rain barrel, and it's actually holding up completely waterproof. it's holding even in freezing weather.

Used on my above ground pool. Sometimes it goes on and sticks fine, oyher times it takes several tries. I like it though.

This product is ridiculously strong 💪 so make no mistakes, it will not come apart. You don't get a lot for the money, but without a doubt it works better than any product I have tried I used it to seal my windows 🪟, great buy!

I saw the commercials for this product showing a guy floating around in a boat with it, using this product to stick underwater, etc. I bought it to patch a tiny hold in my plastic hot tub figuring this was just the item I needed. I first attempted to put it on with water in the tub. The piece I put underneath the small hole with water in the tub did not stick. Okay, I thought, like the ads, I'll just put a piece on underwater over the crack. The second this stuff hits water, it doesn't stick at all. So that was worthless. Okay, I thought, I'll just drain the tub, put the tape on both sides of the crack while dry, let it cure and refill the tub. I was amazed at the lack of flexibility of this stuff, does not go around any sort of bend well at all. Regardless, put the pieces on the dry plastic, let it sit for 24 hrs, then refilled the tub. Within a couple of hours, the interior piece was flapping around in the water. The "stick" was completely gone in both hot and cold water. This stuff is worthless. I really hope no one is actually trying to fix a roof with it, water will go right through it. It does not stick when wet and barely sticks when dry. I'd like a refund, wish I could get a refund on my time spent wasted on this.

This stuff will stop leaks of all kinds!

Not very good. To use it you have to unstick it from itself. I thought it was just the seller was selling old stuff. Nope went by Lowe’s and same problem. If your willing to fight with it, ok

It works really great! My fiberglass bathtub was not installed properly and cracked… I tried epoxy repair kits and even called out three contractors to quote repairing my tub… All the contractors pricing included replacing the tub and all the tile surrounding it. The cheapest quote was $7000… I bought this stuff, slapped it on the crack after a good cleaning and drying and I have no hesitation taking baths and I’m not getting any leaks in the ceiling below… I’m saving my bath rehab money for the future when I can do a better job! It saved me a lot of money and although it doesn’t look great it’s not visible when you walk in the bathroom as it’s on the interior wall that faces away from the room…
