Having recently lined much of the living room in preparation for painting over with emulsion, I'm not sure if the 1000 grade lining paper now hung needs to be primed in any way?
I've been advised that at the very least, the paper will absorb huge quantities of paint - and to buy enough paint for at least 3 coats.
Does the lining paper need to be "primed" in anyway beforehand, before applying emulsion paint?
All help gratefully received!
