Hi all, hopefully someone can point me in the right direction. I've just had a wall hatch closed off and skimmed level, for decorating next month. The original wall is plasterboard that appears to have been lined prior to painting. The new skimmed bit isn't lined and as it's level with wall I don't know if I'll be able to line it. If I paper straight onto plaster, are there any issues I should be aware of? Thanks gents.
