Gorilla Waterproof Patch & Seal Tape 4 x 10 Black, (Pack of 1)

I used these to block unwanted light from skylights in our church building. I think it took 10 rolls. Second picture shows one with and one without.

After trying multiple products to seal a leaking sunroof, I finally got it right with this tape. In the current torrential rain in California it is holding up as it should. Not a drop of water inside! Very highly recommended for waterproof applications.

So far it works to patch holes where I need to

Its not easy to use, but I learned after struggling with it the first time that wearing plastic gloves and using the tip of a scissors to scrape the backing so it could be easily removed made working with it easier. The glue on the back is strong and instantly adhesive so if the cut strip accidentally touches something it shouldnt removing it can be difficult but using shorter strips reduces the likelihood of that happening. I used it on two projects. The first was to repair a large hole in the backwash pipe from my pool filter. So far after several weeks there are still no signs of leakage whereas previously a small fountain of water had been spurting ito the air. The other repair was to a solar pool cover whose seams had come apart. The cover was on the pool, the seams were wet, but the tape held the failed sections together. Only relatively small pieces of tape (about a foot long) at each end of the cover were needed .

Super sticky, scissors used required cleaning afterward. Followed dirxns and rounded the corners of each piece, and covered both sides of the tear as much as i could with the cover already installed. Looks like black duct tape but the pool cover gets leaves all over it anyway, so no big deal. I’ve stepped on it myself and not felt it give; I weigh 145 with a winter coat on. 50lb dog has not fallen through. Perfect.

I am using this to waterproof a door threshold that has asphalt shingles lapped under it. The asphalt shingles cracked under foot traffic. So I am using this to lay over the asphalt and tuck under the metal door threshold to fix a water leak problem. (its a storage space in a two story car garage, and this area gets rain water when it blows against the door.). what I had to do, to make this work is remove the top layer of sand embedded in the asphalt shingles so this tape will lay flat with no voids and all the edges will hold down. This was much cheaper to fix a problem that trying to replace the asphalt shinges (the previous owner glued them down). I used a 6 inch metal scraper to remove the surface sand in the asphalt under the shingles were flat. Then I applied this gorilla patch tape. For extra grab, I used a heat gun while rolling a 6 metal pipe (like a bread roller), starting from center and working out toward the edges. This really helped the adhesives lock into the asphalt. I expect this repair to fix a water leak that was going to eventually cause lots of problems with the framing under the door threshold. Not bad for less than 20 bucks. good stuff

This tape works Ill see how it holds up in weather.

Pond tear

I patched up rust holes on my running boards on my car to keep the weather out and it is obvious the tape will out last my car amazing

It’s okay
