Before wallpapering a new plaster wall, what should be applied?

Before wallpapering a new plaster wall, you apply wall sizing to prepare the surface. Wall sizing is a porous liquid that seals the plaster and reduces its absorbency, giving a uniform, stable surface for the wallpaper adhesive to bond to. If the wall is too absorbent, the wallpaper paste can dry too quickly, causing uneven adhesion, wrinkling, or future peeling.

Primer and sealer are typically used when painting and can interfere with the wallpaper adhesive, while plaster binder relates to materials used in the plaster itself, not a surface treatment applied before wallpaper. Wall sizing is specifically the right prep for wallpaper on plaster.
