Can anyone recommend a good cover-up wallpaper suitable to hide the shadow of a blocked up doorway? Fault shows up depending on the direction of light, despite 2 layers of 1700 grade lining. Will add a 2000 grade liner before applying the cover-up paper. Dont like the Graham and Brown polystyrene stuff as don't want the walls to looks artexed (would rather have the shadow of the door!) Considering the Wallrock Texture by Erfurt. Anybody used it? Will be painting it. Appreciate helpful advice. Please dont suggest a skim, its not THAT bad.
