Auyuiiy Super Waterproof Tape Butyl Rubber Aluminium Foil Tape, for Roof Leak, Surface , Window Sill Gap, Pipe Rupture (5M)

Absolute garbage. Does mot work. Never buy it!!!!

Its been more then a year now, repair to gutter still holding on ok.

Cinta de caucho para techos, para goteras, y grietas, la verdad es que le he utilizado y va muy bien. La recomiendo.

Super-sticky is an understatement! And at £8.99 for a 5m roll this is pretty good value for money. This tape is awesome, I used it to close off a redundant extraction fan vent in my loft. I put an end cap in the pipe and wrapped one layer of this tape around it. Done and sealed! The tape is easy to use, but the glue is so sticky that where the edges of the tape on the roll have touched it's a bit difficult to unroll as the non-stick backing layer gets bypassed! Great product though, will definitely buy again when I finish this roll!

No hace magia pero puede servir para salir de un apuro.

I first saw a video demo of this tape on Pinterest. The demo was very impressive, and I bought a reel on the strength of that. I have found it to be good but not as impressive as the demo. The text on the plastic packaging is all in Chinese. The tape is 50 mm (2 inches) wide, the backing is aluminium tape and the butyl glue side is very thick, I guess about 1 mm. On the reel the glue surface is separated from the aluminium layer beneath it with a separating strip of teflon type material so that you can peel the tape off the reel reasonably easily. I have used it to seal the drain holes in earthenware garden flower pots. Once it sticks, its hard to get off, which is good of course. Don't use scissors to cut it, you will take ages getting the glue off, use a knife. Similarly be careful not to get it on your fingers as it will take a while to get the glue off. Once you remove the plastic packaging don't put the edges of the reel in contact with anything, put it down on the curved surface with something to stop it rolling away. It will stick to anything in contact with the edges as just enough of the glue oozes out of the edges. From experience I suggest that you don't remove that part of the wrapping that covers the edges. The grip strength is almost entirely dependent on how clean you can get the surface you wish to stick the tape to. The aluminium and butyl tape is certainly stickier than any other tape I have come across before. I found that I could remove it from my hands and scissors with HG Sticker Remover (available from Amazon). I tried the tape on two leaks on a garden hose. Although I was careful to clean the hose, the tape failed to hold back the water pressure in both leaks. I then tried to secure one of the repairs with three cable ties over the tape but it still failed. I tried Fibrefix on one of the leaks and that tape successfully sealed the leak. I have bought another reel of Fibrefix for the other leak. Fibrefix is much more expensive as you have to use one complete roll for each repair. However Fibrefix is much easier to apply. Self amalgamating tape might be a more economical solution.
