T-REX Waterproof Butyl Tape for Leak Repair 101mm 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.

This did fix my pond liner but needed tape on both sides of the liner, which was awkward. However, my wellies were cracked and leaking. It some of this to fit, cleaned the service, stuck the tap on and went over them with a hot hairdryer- it did a fantastic job of that.

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!

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 had high hopes for this tape based on the product description and some of the reviews, but it turned out to be a complete waste of money. The first roll didn’t stick once it came into contact with water on the liner. Thinking it might’ve been user error, I gave it another shot and bought a second roll. This time, I thoroughly cleaned and dried the area — even though the product claims that kind of prep isn’t necessary — and it still failed as soon as water was added back to the pond.The tape also loses adhesion when stretched around curves or bends, making it really difficult to use on anything but perfectly flat surfaces. I tried it on both a flat section at the waterline and a curved part at the bottom of the liner — both repairs failed.Maybe I got a bad batch, but after wasting time and money on two rolls, I can’t recommend this tape for any job involving water. To make matters worse, there’s no clear way to contact the seller about the issue.

Very good quality and works well

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!!
