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: Important - read the review! - I tried to fit this in relatively cold weather, which I really wouldn't recommend. You need to make sure the flashing tape and the surface you are sticking it to are warm for it to be sticky. I did try a blow torch to start off with, but this didn't work as good as a hair drier. I worked along the roof in roughly 50cm sections heating the wall, the roof and the tape for a good 2 to 3 minutes before starting to stick it down. If you do it right, it will stick well. It takes a long time, but it does work and it is worth it. It makes a good seal, I think it helped that I did chase it into the wall - I didn't help that I was sticking this on a stone built house and the face of the stone is extremely uneven and unlevel. I haven't had a leak since I put it on, so only time will tell how long it will last for. It is much cheaper than lead though so I can't complain.

## 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.
