Fixing plaster in old house
Hello, I live in a very old house, built in 1875, and I recently started taking the wallpaper off in one of the rooms and the wall seems to be patched with different materials. In one area there is a board nailed into the wall and the rest of the plaster seems to have some kind of coating that is cracking and chipping off. I'm just wondering what is the best way to go about fixing this? None of my other rooms are like this and have been easy to paint so this is new to me.
