How do you prepare walls for traditional wallpaper installation?

Preparing walls for traditional wallpaper installation involves cleaning the surface thoroughly to remove any dirt, debris, or existing wallpaper. If necessary, any holes or cracks should be repaired, and the walls should be sanded to ensure a smooth surface. Applying a primer or sizing to the walls can also help improve adhesion and prevent the wallpaper from peeling or lifting.
