Using a scoring tool, create perforations in the wallpaper. This will allow the wallpaper remover to penetrate through to the wall.
Following the manufacturer's directions, mix the appropriate ratio of wallpaper stripper and water in an empty plastic 5-gallon container.
Using a sponge, apply the remover mixture to a 4' x 4' section. Allow the mixture to soak on the surface for a minimum of 5 minutes. Do not allow it to dry.
Starting in a corner of the wall, peel back the wallpaper in a 4' x 4' section. Repeat the process until all the wallpaper has been removed.
Loosen the stubborn wallpaper sections using a scraper. If some paper backing remains, continue wetting and scraping the area until all the backing has been removed.
Using a scrub brush, scrub the surface to loosen the remaining glue.
To remove the solution and glue residue, wipe the area with a water-dampened sponge or rag.
