Polar TapeSeal Waterproof Repair Tape, 2" x 5 ft (5cm x 1.5m), Black | Self-Adhesive Rubberised Waterproof Repair Tape, Roof, Gutter and PVC Pipe Repair, Leak Sealer, Indoor and Outdoor

Completely fixed the leak in my roof. We've had some awful weather too (live in Wales). I will say the stick was a little questionable; you have to make sure you're working in dry conditions, and it will work as intended. It's been on for 6 months, and I've had no issues come back. I was finally able to plaster the ceiling and paint it. Looks lovely now.

Great tape, sticks well, but slightly too wide for my tape despenser. Will use as good tape but wouldn't buy again due to width.

This is brilliant, leak proof, easy to cut easy to use

Was purchased to address poorly installed boiler condenser pipe which was leaking from several elbow joints. Do not attempt. Contrary to product marketing images, it's too rigid to even stick properly on a smaller-diameter pipes (became part undone under its own tension in a day's time). And it's extremely messy, took forever to clean with rubbing alcohol. You will be much better off with self-amalgamating tapes.

Very good adhesion properties and good flexibility.

Too expensive for 10 cm tape.

Worked really effectively and easy use even at the top of a ladder.

I had a leak in the gutter. It really sticks on contact, so getting it in position without it sticking to everything was tricky. I stuck it inside the gutter as a type of liner application principle. I also had holes in my plastic roof to the shed, which I also fixed with it. All seems okay, with regards to fixing the leaks. This was only a recent job I did in early March 2024, so I am looking forward to see how long it lasts over the next year or so. I can monitor the shed application easily , so I will know in a year if it is a good as I rated it as.

Pretty amazing but not the soft bonding , which would have personally worked better for me . Strong glue . Firm tape

Stopped my leak instantly!@

It is not waterproof. When I spray my terrarium after a couple days it falls off.

Didn’t really care for this product it’s very visible and leaves a very sticky residue

It's been months of rain, heat, and construction dirt. Still, where I'd oversized and can touch the adhesive side It's still sticky- in a good way. The membrane is quality material and should seal well. I used it atop existing post as part of a redecking and only after I'd let them dry. Being spring in KY it always rains. I used foil tape to tent over the post in the interim.
