We have a huge hallway. It has previously been lined in the days when I knew not much about decorating and the decorator lined it. I now know that it probably should have been plaster skimmed. There are areas where it is not too bad and others where the surface is pretty bumpy. I want the whole thing redecorated soon (repainted) and I definitely am not prepared to strip again to have a plaster skim. Can the bad areas be made more flush with a filler and then painted over? On the other hand it is a Georgian house and I don't mind a few lumps and bumps. This forum is great and I am finding out loads of things I was not aware of. Good Work!!
