Putting up wallpaper is a wonderful way to decorate a room. However, removing wallpaper is often quite difficult, especially if there are multiple layers or if the wallpaper is very old. Removing wallpaper from concrete walls requires time and patience, but it does not mean calling in a professional. You can do the task very well yourself. Use household cleaners to remove wallpaper, along with a lot of elbow grease.
Remove all photos or picture frames from the wall. Place any movable furniture out of the room. Cover the remaining furniture, rugs and the floor with drop cloths.
Scrape off the wallpaper using a plastic scraper. Begin scraping in one corner and continue until the concrete wall is visible.
Steam the wall using a steamer to remove any wallpaper that remains on the wall. Let the steam sit for 5 minutes and then scrape off the wallpaper. Begin with a small section at the top of the wall and work your way down. Steam the wall as many times as necessary.
Mix a solution of 1/2 gallon of hot water and 1/2 cup of fabric softener. This solution will remove any stubborn pieces of wallpaper. Apply the mixture evenly to the wallpaper using a sponge. Let the mixture sink into the wallpaper for 20 minutes and then remove the loose paper with a scraper or a putty knife.
Wash the newly exposed concrete wall with soapy water. This will remove the wallpaper glue on the wall.
Let the wall concrete wall dry completely.
