Dilute 5 ounces of wallpaper stripper in 1 gallon of water. Fill a pump sprayer with the mixture. Spray the walls with the mixture. Scrape any residue and wallpaper scraps off the walls with a wide scraper knife.

Empty the pump sprayer and refill it with clean water. Spray the walls again to rinse them. Wipe the surface with a wet sponge to remove any remaining residue. Allow the walls to dry for one to two days.

Sand the walls with a sanding block wrapped in 120-grit sandpaper. Apply a coat of oil-based paint to the walls using a roller. The oil-based paint acts as a sealant to lock in any grease spots, stains or water-based adhesive so they don’t seep through later to interfere with the paint job. Allow the paint to dry.

Examine the walls for loose or flaking bits of paint. If you find any, sand them off. Repaint the areas with the oil-based paint and a paintbrush.
