Q: I just bought some, gives very little information on how to make it stick!

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.

Yes, you can use it to replace damaged lead flashing too, adheres to slate, stone, brick, wood etc,,.

Q: Can this be painted over ?

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.
