Review: Good product, choose weather conditions to apply as the stickyness becomes more when hotter. - Arrived in perfect condition, no knocks to the side of tape. Rolled out nice and clean. Had to make a 90 degree bend in the tapes 100mm width, which it did very well. The weather was cold at the time of installation, which in my case, was good, as the tape was easy to place without always sticking to itself.
Review: Easy enough to apply, nice and sticky. - I used this to seal the bottom edge of my workshop/shed which has a small leak allowing rain water in. It was easy to apply, nice and sticky. Even with this cold weather spell (around 7c, the product recommends applying in 5c or above), I used a blow-torch to slightly heat up where I was applying it anyway. I used my gloved fingers and took my time to press along the edges and it stuck on, ensuring I pressed edges into any grooves/dips inthe wood of the shed and well into/over any screw holes. Time will tell if it works good, but given how well it went on I have good hopes it'll do the job! If I can update/edit this review, I'll report back in a few weeks and let you know.

## 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.
