Prepasted Wallpaper
Prepasted wallpaper has a built-in adhesive that makes removal easier. To remove prepasted wallpaper, use a solution of warm water and a mild detergent to loosen the adhesive. Scrape off the wallpaper with a putty knife or a similar tool. Rinse the surface with clean water to remove any remaining adhesive.
Non-Prepasted Wallpaper
Non-prepasted wallpaper requires additional adhesive to be applied before installation. Removing non-prepasted wallpaper can be more challenging, as the adhesive has already dried onto the wall. Use a wallpaper remover or a solution of equal parts water and white vinegar to loosen the adhesive. Scrape off the wallpaper with a putty knife or a similar tool.

Textured Wallpaper
Textured wallpaper has a unique pattern and texture that requires special care when removing. Use a textured wallpaper remover or a solution of equal parts water and baking soda to loosen the adhesive. Scrape off the wallpaper with a putty knife or a similar tool.
Preparing the Surface for Paint
