Wallpaper adhesives

Standard wallpaper adhesives are based on methyl cellulose, a white powder which is water soluble giving a colourless solution. For fixing the heavier papers and decorative dado strips, polyvinyl acetate (PVA) is an added component. Cold water starch is also available as both a wall sizing agent and wallpaper adhesive. Most wallpaper pastes contain fungicide to inhibit mould growth. The standard BS 3046: 1981 describes five types of adhesive ranging from low solids to high wet and dry strength with added fungicide.
