Polar Specialist Coatings Premium Black Waterproof Tapeseal Sealant Repair Tape 4" x 5ft

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.

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

Nice sized lettering and well lit, a great phone for elderly, very easy to use once it’s set up, setting up takes time and some basic skills.

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

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.
