How to prepare you wall for wallpaper

Before wallpapering the walls need to be prepared

Surfaces painted with acrylic paint; Old Gib-board (often yellowed); Plastered walls; 

  • Seal with oil based pigmented sealer and allow to dry
  • Sand with 80 grit sandpaper to give key for wallpaper, dust off, and then size.

New Gib-board (recently installed):

  • Apply size (two coats). With light coloured wallpaper especially paste-the-wall it may be necessary to use oil based pigmented sealer to prevent contrasting wall colours showing through the paper (shadowing or photographing).

Enamel painted walls:

  • Sand surface well with 120 grit sandpaper to give a key for the wallpaper, dust off and then size.

Wallpapered walls when stripped:

  • Fill any damaged areas and then sand with 120 grit wallpaper, dust off and then size.
  • Seal with oil based pigmented sealer, first if the paper is a light colour and there is a chance of the contrasting wall colours showing through.

Note for acrylic painted walls being wallpapered:

  • The acrylic paint will swell up and may start to break up under the wet wall-covering and cause adhesion problems for the wallpaper.
