What role does sizing play in hanging wallpaper?
Sizing is like paint primer that ensures the wallpaper adheres to the wall. It should be used even when wallpaper comes pre-pasted to insure adequate adhesion. There are different types of wallpaper adhesives to address the unique requirements of various types of wallpaper. The most common adhesive or sizing for do-it-yourself (DIYs) is premixed vinyl. If you decide to use a wall covering that requires a different adhesive, you should consider using a professional paper hanger.
