Polar TapeSeal - Rubberised Waterproof Repair Tape for Roofs & Gutters - Leak Sealer for PVC & Plumbing Pipes - Easy to Use DIY Tool for Indoor & Outdoor - Black - 2" x 5 ft (5cm x 1.5m)

Brilliant easy to use tape. Kept my shed water tight last winter until I got it repaired. Very sticky and lasting. Builder asked me what it was because he couldn’t get it off ! Highly recommended.

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.

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

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.

Really good extra thick tape as described by the seller quick delivery

Used this tape on a white ogee gutter joint. Due to the peculiar shape I had to repair I found it was best to apply to both the inside and outside of the gutter joint. I used a non-adhesive tape to make up templates and cut the adhesive tape from that. I used a Stanley knife on a metal slatted garden table. This way there was no damage to the table etc. I started to peel off the tape, adhered the sticky side to the gutter and as I pressed it down I slowly peeled of the remainder as I went. Worked first time and was instantly waterproof again. The tape is clear according to the advert but in truth there is a very slight, very light blue hue to it. Not noticable unless you know where it is and take a close look. An added advantage to using this tape is having fingernails. Without them I can imagine it being quite difficult and awkward.

It works with the roof of my shed. But one role of that cannot even cover the joint of the felts of my small shed. It is very effective but quite expensive.

We had a few small "splits" in our roofing felt inside of the attic and a couple of places where the felt had come away from the piece it previously overlapped and was causing draughts. I didn't use a heat gun but the attic wasn't cold and I heated the tape (the sticky side of course) and felt with a hair dryer before immediately putting the tape on the required areas. Initially it stuck like "Muck to a blanket" and seemed impressive but 1) I estimated I'd need circa. 4ft and there was only about 3' 6" of tape and within 4 hours it started to come unstuck around the edges and by the next day it was literally hanging off. I managed to re-heat it and put superglue gel around the edges which managed to hold it in some places but not others. A complete waste of time and money and I should've stuck to using black duct tape from £1land with spots of superglue gel around the edges which I'd done before (but was messy). If I could give less than 1 star I would.

Sticks very well and holds up well so far. Have had several rains and multiple days/nights of high winds, 30mph+ stronger gusts.

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

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.

It worked well for some items I sanded first another one where I had the sand oily surface didn't stick

Used it to repair leaking rain gutter. Didn't work and came off after first rain storm.
