Step #1. Remove old wallpaper with the help of the wall scraper. If the process turns out to be difficult to do, you can also use a wallpaper steamer or a solution of warm water and vinegar (in 1:1 ratio). It should be abundantly applied to the old wallpaper with the help of a sprayer, left for 15 minutes, and then removed with the scraper. If you notice any mold or fungi, remove it before you move on to the next step.

Step #2. Fill any gaps (cracks or holes) in the wall with the help of the spackling compound to get a smooth surface. Let it dry. Sand the wall with the help of the sandpaper, removing wallpaper and spackling compound residue. The surface should be clean, dry, and matte so that the new wallpaper adheres well to it.
