Wall coverings that necessitate the application of adhesive directly to the wall surface prior to installation are categorized as unpasted. This differs from pre-pasted options, which have adhesive already applied to the backing. For instance, a textured vinyl requiring wallpaper paste for adherence exemplifies this type of wall decor.
The use of unpasted varieties allows for greater control over the bonding process. This is particularly beneficial when dealing with unique wall surfaces or heavier materials. Historically, all wallpaper required separate paste application; pre-pasted options represent a relatively modern convenience. This control over adhesion allows for potentially longer-lasting and more secure installation, particularly in high-humidity environments.
