I have some walls that need skim coating because wall paper was removed and bits of finish plaster have fallen out. In places the base coat has also fallen away. I was going to PVA the walls and fill any deep holes with bonding plaster, and then skim coat the lot.
What is best for skimming to go over paint, raw plaster, etc? When I lived in Canada, everything was dry-walled, so one would just skim with drywall compound, with a little PVA added if the surface was tricky (ie. glossy paint). Here there is both ready mix and powdered finish plaster products. I guess the first cures by drying out (like drywall compound), but the second cures by a chemical reaction.
Is there any reason to prefer one over the other?
