I have ripped off the wallpaper from the walls of my bedroom, and I am now planning to fill the holes in the wall, skim the walls with plaster, and then paint. I’d like some advice on this as it’s the first time I try. On another forum, I have been advised against using PVA for priming the walls before skimming, because the walls and old plaster are porous (the bedroom is in an old victorian building in Edinburgh). Do you have any suggestion on what product I could use for priming the walls if not PVA? Or is it enough to sand and wash the walls with water before plastering? Also, any suggestion on good ready mixed plasters that I can find in UK? (or if you think that it would be better to use plaster in powder, could you explain why and possibly suggest good brands?)
Here are a couple of pictures of the walls to give you an idea of the job:
Cheers :D
