Review: Great value flashing tape that sticks well - A bit tricky peeling the backing off but this stuff is great. Used it to repair my flat roof where it had a crack & to seal around a stack pipe that went through the roof & had been bodged with silicone they shrank leaving a gap. Sticks really well, no rain to test it yet but looks like it will do the job.

## Questions & Answers

**Q: I just bought some, gives very little information on how to make it stick!**
A: You want to place it in the sun for an hour if possible before use. If at room temperature it should stick to many surfaces. If not, heat briefly with a gas gun as you lay it on. Also you can use a wallpaper edging roller once it’s in place to help make it bond.

**Q: Will it work to stop lead flash slipping on a slate roof.**
A: Yes, you can use it to replace damaged lead flashing too, adheres to slate, stone, brick, wood etc,,.

**Q: Can this be painted over ?**
A: I’ve only used sealant paint on it no problem, it sticks to it and doesn’t peel off. 
I think gloss paint would be fine.

**Q: is it butyl**
A: Yes, needs to be heated slightly, a hairdryer works and is then very easily worked into place.

Does the work highly recommended sticks very well and good quality used before and have no problem with the item and seals very well

### ⭐⭐⭐⭐ Good product but beware of the size
*by R***Y on 17 November 2025*

I used this to create a waterproof bond between the house and a lean-to, but after about 4-5 months it has slipped/dropped off the wall and has let water in during heavier rainfall. I used the recommended Bostik primer (black markings seen in photos) which I had hoped would mean this wouldn’t happen. I would recommend going for a size (width) larger than you may think, as I will have to redo this again.
