Hello all,
I stripped back my horrendous bedroom wallpaper with a view to painting but found one of the walls (the window wall) had been lined with a kind of foil paper, which I didn't remove.
a) What is it! I presume its to protect against damp or something
b) Should I leave it there?
c) If I do leave it can I paint directly over it with an adhesive type of paint or do I have to re-paper that section of the wall?
Your suggestions would be grateful.
