## Questions & Answers

**Q: can you use it on wood**
A: It's just a white paint so can be used on anything, or at least I did.

**Q: If the wall is to be plastered would this have to be applied first or after the plaster (skim)?**
A: If you have dampness don't plaster the wall till the damp problem is fixed, if the wall is dry and only marked then once skimmed and dry will be fine for paint finish etc.

**Q: Can you use it on a floor**
A: yes, but you have to put down several layers, make sure the floor is dry.

**Q: Can. I paint over wallpaper**
A: I personally wouldn't, I would remove the wallpaper as if you have a problem with damp you need to get back to the wall to clean and treat that before you paint on the damp seal.
