You might need some TSP to clean walls that are greasy and grimy, like kitchen walls. Keep in mind to not soak the walls with the water or solution because it could soften the adhesive below the wallpaper and cause it to loosen or bubble. Let the walls to dry overnight.

Step 2: Repair any damages to the wallpaper

Use a thin layer of wallpaper seam adhesive to reattach peeling edges or seams. Or you can use putty knife to lift those areas and cut them with spackle to create a level surface. Then sand lightly when completely dry. If the wallpaper has a texture you don’t want to detect through the paint, the whole wall should be sanded until smooth, using either a palm or orbital sander. With a slightly damp cloth, wipe away dust.

Step 3: Tape off molding and trim

Carefully tape off any molding, trim, wainscot, or baseboard you want to protect with painter tape.

Step 4: Prime the walls

Always use oil-based primer and don’t use water-based one. That’s because a water-based primer could soak into the wallpaper and loosen the adhesive. An oil-based primer will not do that. Then let it dry and make sure there is plenty of ventilation in the space.

Step 5: Start painting

Once the wallpaper is cleaned, repaired, and primed, paint it as you would any other surface. Most of the time, You’ll need two coats, with plenty of drying time in between. Especially when your wallpaper has a bold pattern, or if you are applying light-colored paint over dark-colored wallpaper.

Painting over wallpaper can be done, and sometimes it should be done rather than removing the wallpaper.
