I am in the process of removing wallpaper from my dining room walls. At several locations on the walls the paper is coming off along with every coat of paint right down to the sheetrock. I am planning to paint these walls rather than wallpaper but the areas where the paint pulled away are definitely going to show through. I was thinking of trying to put a coat of joint compond over these areas which is going to be difficult to keep flush. Any other ideas short of putting up new sheetrock?
