Confused about wall layers during wallpaper removal
Hey, first home owners on a budget and trying to diy our walls.
It used to have wall paper and we want to remove it and paint the walls.
While peeling, we have come to realise that we don't know which layer is the gib (?husband calls it this).
The first image is the bedroom, has the grey layer, then beige, which should be the wallpaper backing, then a dark orange toned brown, then a cooler toned brown. second image is living room near the curtains wall paper and backing came off easy, then under the orange toned layer is white? Which seems to have wood or something under it.
Any help at all will be helpful!
