surface/ surface preparation for all coverings

the surface needs to be dry, sustainable, flat, clean, evenly absorptive, and neutral in colour or white. remove all wallpaper with wallpaper remover. even out and close rough surfaces, holes, and uneven spots with filler containing plaster. for equal absorptivity and reinforcement purposes, plaster surfaces should generally be treated with water-based primer. flawless decorating results can only be achieved on surfaces of uniform colour, so lining paper or pigmented primer should be used.
