4" x 5' Black Waterproof Repair Tape - Strong Rubberized Bond, Instant Leak Stopper & Rescue Seal | Heavy-Duty Silicone Tape for Pipes, Roofs, Electrical Repairs (3 Pack)

Junk.Came flat packed so had to throw half away as there was too much of a kink in it, so only got to use about 7 bits of 5” after cutting off the curvedBits. Not in a roll as pictured.No way there is 5’ on there. Probably 3-4 at most.Drained pool. Dried then cleaned area. Fixed tape and within 2 hours it started lifting. Tried again and tried fitting with heat gun, but happened again on both inside and outside of pool liner.Rubbish.

Absolutely crap followed instructions to the word doesn't seel anything should've bought the gorilla tape

I bought this tape to seal a leaking gutter, I did what it said but it's not flexible and it didn't stick at all and it's not waterproof, complete waste of money.

I brought this on other reviews that gave a good 5* but honestly who are they kidding,, it’s absolutely rubbish wanted to fix a small tear in my blagdon pond ,it didn’t even work, it curled up on the sides, still pee’d out the water , false advertising or this not the original stuff from tv , would not recommend

Used this to cover 2 holes in the pool without emptying it. Hole 1, cut 2 pieces about a cm bigger than the small tear. stuck one inside the pool one outside. The tear was close the seam at the bottom. The second hole was tiny and was like a tiny spurt of water, also close to the seam. Couldn't see it from inside under water so just stuck the patch outside. 3 months on the inside patch has come away with the kids brushing against it but the outside patches are still holding. When it is empties I will mark round the patches with a sharpie pen in case they come off. Finding a tiny hole inside a 3mt x 2mt pool is a nightmare!

This stuff is supposed to stick under water?? I had a pin hole (dripping) in a material large pool. Thought I'd give this stuff a try, cleaned and dried the area and applied a section of this tape way larger than the surrounding area.Warmed it up and stuck it on, pressed it down nicely. Came out this morning and the patch has peeled off and has had no effect. This stuff is def not good for any wet environment.Also like other people have reported, when the tape arrived it was squashed flat and not rolled up, so again kinks and separation in the tape, ruining some of the tape.Def would not bother again, might be ok for craft applications but it certainly doesn't do what it says on the tin.

I was hoping to stop a leak in my corrugated garage roof where the bolts were securing two sheets together I first bought a liquid spray which was far too thin very black and very ineffective so as per the advert this looked great too but my thumb is more sticky than this supposedly adhesive tape.It is a TOTAL waste of money. DO NOT BUY.It was from Amazon themselves so at least one got one's money back immediately the return was scanned in at the return drop off shop. There was also a wait of three days before the Amazon system that the drop off shop was using was functional which meant I had to make three visits to send it back. Quite impressive overall!

Despite the hype, it did not stop a leak in a water butt. Maybe it is because the shape was slightly curved and not flat. Applied the tape as advised on the instructions, but the water kept on leaking out from behind the tape. Will not bother using the rest of the tape
