T-REX Waterproof Butyl Tape for Leak Repair 48mm x 1.52cm

Very sticky and waterproof value for money

I have a very large football sized hole in my pond liner right at the water line., caused by rats when the pond was surrounded with decking that they loved under. I attempted to fix it in early Summer with a piece of liner and the waterproof pond liner repair silicon (can’t remember the name but it’s the one in the yellow cartridge). Well it didn’t work and within a couple of weeks the pond was leaking until I was topping it up ever couple of days.So decided to try this. I did not apply it under water. Instead let the pond down so that the full hole and an inch or so below it were fully exposed and could dry out. I applied the tape on the underside and top of the liner, so that it overlapped the liner by 2+ inches all the way around and then stuck to itself over the hole itself. I didn’t add any patching liner. That was on August 31st and I’m writing this on Sep 24th. So far I have been able to have my pond filed half way over that taped hole and haven’t had to top the pond up once since (other than when I backwash clean the filter, of course).The liner I have is a Swell plastic liner, which I heard apparently requires a swell patch kit to fix any problems. This tape is proving that wrong so far. Will update this review if/when the tape starts to peel away.

Why did you choose this product over others?:Chance

Our large rectangular bestway pool was on its last legs this summer, but I didnt want to invest in a new one yet so I thought there was nothing to lose trying this out.I was gobsmacked. I used it to patch up the obviously worn parts of the lining where I knew it was leaking after cleaning the pool.Once the pool was up it started springing leaks, I was skeptical about how it would fare with water actually coming through as you stick it on,but by applying in one direction drying around it as you go, it sealed the hole and remained water tight for the rest of the month.I will definitely be keeping some of this on hand for emergencies!

The media could not be loaded. Absolutely useless yes it sticks to your fingers and is difficult to apply even on a plastic pipe to seal a water butt. But will not stick to anything that is already damp or wet. Gutted absolutely a waste of good money do not buy.

it's not that sticky and it will not stick to silicone at all. It will not stick if moisture is on the surface either.poorest tape I've used so far.

I bought this to patch up my dogs paddling pool. Yes I am that person.It’s fantastic!! Super strong tape, super sticky and the water level hasn’t dropped even after a week!!

I used this to patch over a 1cm slit in the bottom of a 16ft pool, just next to the drain plug. It was heated at the time to 30° and full of water. I guess the pressure of the water helped keep it in place. However it stopped the leak and saved me draining the pool. It has been 2 weeks and counting and it's still not leaking.Very impressed
