My house was built in 1927 with plaster walls. For years the bedroom was covered in ugly paneling. My husband and I just removed the paneling and the four layers of wallpaper under the paneling. By the way, thanks for the tip about removing wallpaper! Most of the plaster is looking good but with little holes. The outside wall near the chimney has had water damage and the top layer of the plaster has come off in a few spots (1 1/2 feet in diameter) and is discolored in that area. The layer underneath seems fine. How can we repair the surface layer of plaster? I only see videos on how to repair it when it's down to the lath.
