Tom Grey Verified Purchase

A fibreglass flat roof was leaking, quite badly. It needed fixing quick as there had been lots of rain and lots more to come. Just used the tape to hold down waterproof patch as I can't weld or glue fibreglass. I cleaned the areas well and then used alcohol to clean it again. Then stuck the tape down and it held very well. It also seems waterproof. So did what wanted it to do. I just wish the roll was longer!

Goreally Sticky Stuff!

Perfect for repairing tarpaulins, particularly the roofs of workshop tent structures. The bond is instant, even on wet surfaces or when applied in the rain. Although a little expensive, it is worth it to extend the life of a cover during bad weather.

Stick it , seal it

I can’t recommend this at all as it states it sticks onto wet surfaces and it doesn’t at all. Maybe when dry but certainly not wet as described. Total waste of money

good stick

Despite packaging saying it's suitable for roof repair it failed to be stuck to a shed felt roof that needed patching. Just fell off. I recommend you look elsewhere.

Probably my fault for not checking, but this will not stay stuck to vinyl wet room flooring, even roughing it up/keying it etc. so if your mrs drops something and puts a crack in it, like mine did 😂. this won’t help, not even for one shower. It might be useful for some other situations, but for me, most pointless £20 I’ve ever spent

Had some very difficult to reach old copper waste pipe hidden in a boxing that was leaking, this was very affective in preventing the leak.

I got carried away and brought a massive shed years back with windows . I am keen to make it last as long as possible. Now my shed is leaking all over the place. I used this to patch repair the roof and used this to reinforce the windows. It’s been rain all week here and zero leaks. So far so good. Hope it survives winter and beyond.
