Smooth the Wall
Old nails and flaky paint should be removed from the wall to keep it smooth. Remove any outlet covers and light switch plates also. These should be easy to remove with a screwdriver, but it’s best to turn off the electricity in the room first to prevent a potential shock.

After you have taken out all the removable items, you probably still need to work on smoothing out the remaining areas. Use sandpaper on uneven surfaces to reduce bumps, also vinyl spackling paste helps fill any gaps. If your wall is textured, wallpaper installation on these types of walls may result in mold-friendly micro-pockets. Apply a layer of joint compound, also known as drywall mud, to try and smooth it out.

Wash the Wall
It’s necessary to wash the wall after it has been smoothed. Also, this process needs to be repeated, right before the installation of wallpapers. There might be a variety of tiny dust particles on your wall after you’ve sanded it.

To remove grease and other buildup, use a powerful cleaner on the first pass, such as sugar soap or TSP (trisodium phosphate). Using a mixture of hot water and a small amount of vinegar will work if the wall already has paint on it. Then, about 24 to 48 hours before hanging your wallpaper, you should go over this cleaning step once more with a soft, damp cloth.

Apply Primer
It’s crucial to test the surface’s suitability before you start applying the primer. Apply a small amount of primer to a spot on the wall to accomplish this. Check back in 24 hours to see if there is a problem with the primer.

If you decide to paint walls before hanging wallpapers, you need to know that it may take up to 30 days for some paints to fully fix. So be sure to give a freshly painted wall a month to dry before hanging wallpaper on it. However, the primer dries very quickly, so you only need to wait a day or two. You can hang your wallpaper after the wall has dried completely and 24 hours have passed.
