Gorilla Waterproof Patch & Seal Tape, Black Tape, 4" x 10' (Pack of 1) - Permanent Weather Resistant Seal for Leaks and Repairs

This waterproof tape is amazing! I bought it to cover a hole in a plastic pool I had in the backyard, and it worked perfectly. Honestly, I didn’t expect such great results, but it lasted the whole summer without coming off. I’m really impressed with the quality—it sticks well and does exactly what it promises.

I used this to patch a strip of the fiberglass on my motorhome that had become separated and delaminated from previous water damage. It holds amazingly and will keep things in place and dry until I can fix the issue with epoxy. It's very sticky and thick.

The text beyond the line is the review from a different reviewer named Mark from June 21, 2022. I literally screenshot his review so I could repair my own 1,200 gallon vinyl pool. I had only one tiny hole spurting water on the seam of the side and the bottom. I couldn’t find the patch that came with the pool, so I was hoping for some sort of solution. So far, after one week, so good!I will add, be conscious about where you set the tape roll when not in use. It is so sticky that you’ll ruin any paper or susceptible materials with the adhesion of the side of the tape.______________________________________________Okay, so this is Gorilla Tape. Gorilla tape works, we all know this. But what about underwater?So my brand spanking new vinyl liner pool decides to spring not one, not two, but three leaks on its first fill up.3000 gallons of water to fill this thing up, I wasn't going to empty it! I live in a desert, I felt guilty enough filling it up, emptying it out to fix a hole and then refilling, no way.So I researched a ton of different patches and came across this product here on Amazon. The reviews were weird. Yes, I read them just like you are doing now. Some say it didn't stick at all? Another says it comes off the roll really loose.Here is the scoop - there is an error on the directions for this tape.So, let's do two things here together - One, know you are not wasting your time, get this product. Right now, don't waste time!Two, read below on a couple of important but easy steps on using it.1) The directions tell you to cut off the piece you want and then round the corners. Here is something important: Do NOT - guys, read that again - do NOT - use your wife's good scissors or the ones in your knife rack. Don't do it guys. The residue left behind was like crazy glue. It sticks! Your best bet is using a decent pair of scissors and making your cuts in one smooth motion. This will prevent goo from getting on your scissors.2) AFTER cutting, get to where you need to place the tape and then REMOVE the transparent liner over the sticky part of the tape. The directions never tell you to remove this liner! Well, to those people with the negative reviews, they didn't remove the liner. Once you remove it, watch out - it is sticky as can be! Try not to touch the sticky part!!We took the tape, sticky exposed, went underwater, and stuck that bad boy right where the pool was leaking. Pressed all the air out, pressed down on the edges, then just stood on it for a few minutes.Did this for all three holes and not one has leaked again.Okay, so it isn't as pretty as some of the other patches, it is a big black piece of tape. But it works and works fast and it is easy.Buy with confidence.

Four stars because it helped but it did not fix the issue. They were difficult to cut, but I know that means it’s strong. My hot tub is a lost cause, I was very hopeful with this tape though.

This is great for certain projects that require water sealing. It is like a flashing tape but the backing is very soft and sticks like Butyl if in fact it is not. It would be very difficult to remove and clean up.

I needed this to patch a crack on the inside of the tub side and this worked perfectly. Cut a strip to adequately cover the crack, removed the protective strip covering the adhesive side and then put it over the small crack/gap. I pressed it on and held it for 30 seconds and it was good to go! I waited about an hour before use to make sure it was set. It’s a great alternative rather than replacing a whole object, you can just apply a quick fix, if possible. I hope this helps!In Christ,Mikey

Ok im trying to select 2 stars but wont let me.... should be waterproof so used it in the bathroom. I have it at the floor base boards, around the tub both in and out of the shower. Held up ok until winter and expand and contraction started to be an issue... now its coming away in the shower and leaving weird tacky residue. Am i using it as intended? Not exactly. But if it works to waterproof and seal an rv from the outside elements on the outside, why wouldnt it help in the bathroom? Now flexseal tape... thats what replacing this when i get the motivation to peel and clean it off of course... stickyness should be an X not a check...

The Gorilla Waterproof Patch & Seal Tape is very sticky and holds on extremely well, even in outdoor conditions. Once it’s in place, it stays put, making it perfect for tough repairs.I used it to patch up the under skirting on my camper, and it worked great—created a solid, waterproof seal that looks like it’ll last a long time.Bottom line: Super sticky, durable, and reliable—excellent for camper repairs or any job where you need a tough, waterproof seal.
