Room has been painted, then top half wallpapered over and a nice big boarder applied in the middle. Trying to remove to just paint the walls, however when taking off the wallpaper and boarder the big areas of paint underneath are then coming off as well and trying to remove the rest of the paint (cannot use a scrapper as that damages the plaster) is sooo slow. Really don't want to have to use lining paper as hate it. Any tips??
