Spray the wallpaper remover solution evenly over the bare wall from which you have stripped wallpaper, working from top to bottom. Many solutions come premixed, but you may need to mix the solution with water, depending on which one you purchase.
Soak the wall with the solution for 15 minutes.
Scrape off the glue by wedging the scraper under sections of glue and forcing it off the wall.
Wipe down the wall with a sponge moistened with warm water to remove any small pieces of remaining glue.
Spray the wall with additional solution as needed to remove all larger sections of glue. Most solutions remove the glue within one application, but some glues require additional applications.
