Polar TapeSeal Waterproof Repair Tape - Sealant Tape - Black - 2" x 5ft

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.

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.

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.

Very good adhesion properties and good flexibility.

I bought this tape at half price and it is still too expensive! Only 50 inches on the roll, not 60 inches as advertised! As far as how good it is, only time will tell. I cleaned the surface it was used on, but I had to warm the tape to get it to stick. It is not very flexible, so probably best used on flat surfaces, or wrapped around pipes etc. Expensive for what it is.

I used this stuff to patch a tear in the felt on our garden shed. I placed two strips along the length of the shed and then went over the top laying it across. This used the entire roll. The adhesion was very good and the tape comes with a film protecting the sticky side so it can be rolled out and cut to length easily. I'm in the west of Scotland, so nothing is ever really dry - I stuck this down at lunchtime on a two day stretch without rain and it went down well. It rained the next day, and it looks like it's doing the job. If it lifts or fails in the next month or so, I'll edit this post, but so far so good for this type of repair.

Not suitable for repair of felt roof. Does not adhere to the existing material and after some rain came away completely. Also 5ft of material for price would make this expensive even if it had worked.

Excellent apart from it doesn't go far- expect more coverage for price

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

Stopped my leak instantly!@

it's ok but not the best

Absolute waste of Money. It doesn't stick. Yes, cleaned the surface as best possible but next day gaps all over. Doesn't even stick let alone waterproofing. Used already so can't return or get my money back. Very Frustrated.

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.
