HOW SHOULD THE PREPARATIONS BE?
The walls must be smooth, dry, dust-free, oil-free and neutral white. Seal the holes and cracks in the wall with filler or sand so that they are smooth. First apply a fixing primer to the wall. For this, primer, stabilizer, or a single coat of white paint is recommended. This practice reduces possible color differences or stains. It also prevents the risk of loosening the wallpaper as it is new plaster. Proper floor preparation requires greater sensitivity to possible transparency when applying thin or light-coloured wallpapers. Plain coated wallpapers are recommended instead of primer or white paint. If you are purchasing more than one roll of wallpaper, check the manufacture code for each, which must be the same to avoid possible color differences.
