Review: Excellent product - I used this very sticky flashing tape to repair rotting, but very dry wood on the lower half of my summer house doors before - the rain arrived. It worked a treat! I used 2x10m rolls and this completed 8 doors perfectly using 4 x15mil wide strips on each door panel (43W x 47H) Don't forget to allow extra for the overlaps... I used very sharp, long-bladed scissors to cut the required strips and it cuts like butter and is easily shaped. I found a knife 'gummed up' very quickly and did not cut nearly as neatly as the scissors. It's worth having some white spirit to hand to clean your tools. Don't be tempted to pull the backing off before you have the flashing in exactly the right position. Once it's stuck it's a nightmare to unstick! Be advised that it comes off the roll wrinkled and there's nothing you can do to iron them out. You can overpaint easily with water based paint. (two coats.) I would recommend for all sorts of jobs.
Review: Didn’t seem that sticky but 6months later still tight on the brick walls. - I got this to seal the polycarbonate roof against the house. The 6m run was easy to fit and used a small roller to press onto the brick work. Didn’t seem sticky but bonded on the wall well and checked after 6 months and it’s still tight on the wall. Very pleased. Great value for money.

## 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.

### ⭐⭐⭐⭐ 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.
