We are considering buying a wonderful old house. Built int he late '20s It has beautiful woodwork but the walls are all horizontal wood. I don't belive it would be possible to put drywall on over the wood walls without removing the facings, etc. and I would not want to risk breaking some of that beautiful old wood. The walls have had canvas and wallpaper but it is in bad condition and will have to be replaced with something. Is it possible to plaster over the wood walls? Or is there something we could do so that the walls could be painted instead of wallpapered?
