Our bathroom has textured plaster work that seems to have been put on over the top of wallpaper. You can see some of the seams and the wallpaper was also still there under a mirrored cabinet. Above the door, for example, the wallpaper is peeling. We would like to get rid of the texture on the walls.
Would it be possible to just take down the wallpaper that the plaster is on top of and hope that the walls underneath are acceptable for repainting?
Or
Can we sand down the textured plaster work?
(We would like to be able to paint and have it be a smoother surface).
