Gaffer Power Black Butyl Waterproof Repair Tape | Heavy-Duty Seal for Leaks, Cracks & Roofing | Flexible, Stretchy & Weatherproof | 4 Inch x 5 Feet

I wanted something to patch my blow up Kayak, the next time it gets a hole. This tape is thick and super durable and super sticky. My first repair was to an outdoor plastic storage box. It had developed a few cracks in the top from weather and abuse. The tape went on nicely, conformed to the curves of the top and it completely sealed the cracks. I know this because there is a slight dip in the top and rain water collects there and the tape does not let it seep through. I see no issues with edges creeping up and the container sits for hours in the sun each day.As for the Kayak, I have not actually done a repair yet as I don't have a current hole, but I know it will work great. I precut some smaller patches from the tape roll so that I can have them ready when deploying my Kayak. Great product. Premium quality.

Happy to have this heavy duty tape ! It makes repairs look neat and clean. Strong and waterproof, but not big bulky and messy looking! My car headlight cover cracked due to a minor crash. This tape did the trick! Provides a strong, protective, water-proof covering that stays in place. The adhesive is strong, but the sticky stuff can get a little messy when on a warm surface, like on the surface of a car, near the engine. A good, strong, clear, protective tape, indeed!!

Went on easily and the adhesive is very strong.

Good product and service. Thank you.

Kept knocking wasp nests from the soffits all summer. Noticed that they were leaving holes in the soffit. Didn't want to spend money on new soffits at this time so I caulked and patched. That didn't hold up. This last time, I caulked and patched and then covered with the white Gaffer tape and it's holding. The surface is too slippery for the wasps. The tape was much thicker than I expected. So far it's held through two weeks of heavy rain and wind. The only caution is that the adhesive material, 'glue', is extremely strong. It's necessary to cut the exact size needed then peel the backing paper while installing along the length. Sort of like using contact paper except that contact paper can be pulled apart. If the Gaffer tape clumps together, forget it. Strong adhesion is a good thing for endurance so it's not really a negative feature. Just a bit tricky to install. But, knowing this ahead of time should help.

Very strong, thick, and sticky. We used it on a leak on our east-set pool, on the blow-up part. However, with the extreme heat, the sticky melted and then bubbled underneath from the air leak. I think it would work great on another surface that doesn’t heat up so much. I have several squares left and will definitely use them on other surfaces as needed.

This is good stuff! We moved into a new house in August and after a good ice and snow melt last week I noticed the eavestrough by our garage door had a few leaks in seam areas that dripped water that then freezed on the area we walk. I got this tape and put it up and it has solved the problems! It feels sturdy. The adhesive is nice and it is malleable enough to mash it into hard to reach areas in the eavestrough. Standing on a ladder is not somewhere I want to be daintily putting some weak tape down. This tape went where I wanted it to go and stayed there. I look forward to finding other leaks to use the rest of the roll and the FREE roll they are sending me! Just read the label on the tape before you discard it. Good stuff, I highly recommend it for a quick repair of a Buffalo area eavestrough in the middle of winter!!

I had this on my sunroof of my Cadillac SRX because the original tape withered away. The first rain storm the under side of this tape was soaked and the interior of my car was a swamp. This stuff is garbage.
