Wallpaper primer is a specific type of primer used on walls before applying wallpaper.
Sometimes referred to as a pre-wallpaper primer, its purpose is two-fold:
- To improve adhesion: This ensures the wallpaper adheres well to the wall surface.
- Make it easier to remove wallpaper when it's time to redecorate: While improving adhesion, it also prevents the wallpaper from sticking too well, facilitating easier removal down the line without damaging the wall.
Effectively, it creates a suitable base that allows the wallcovering to stick firmly but also permits relatively easy separation later.
