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.
