So I bought a house a week about and the living room is plaster and I think the room ceilings are wood with a skim count of plaster over them. Am I better off scraping it all down and redoing it again with plaster or pathing the spot and try matching the pattern or can I just scrape it all down and paint over the wood as if it where sheet rock. I have can hang dry wall sparkle and all that but have no experience with plaster at all. Any ideas are helpful. Thanks
