Helpful Tricks to Remove Wallpaper
Removing old wallpaper can be a hassle, especially if you're a first-timer. Luckily, there is plenty of information available so that you can learn from other people's mistakes. While wallpaper removal is inherently messy, it doesn't have to be difficult. It does require a lot of patience, especially if you are removing old wallpaper from a large area. Before you begin removing wallpaper, it can be useful to determine what lies beneath the paper, whether you have drywall or plaster. You can tell which type of wall you have by feel and sound: Plaster feels hard, cold and smooth and doesn't sound hollow, whereas drywall sounds hollow and isn't as smooth feeling as plaster.
If wallpaper is literally peeling itself off the walls, you might be able to remove using nothing more than your hands and a putty knife. When the wallpaper is this easy to get rid of, all that remains is some glue, which can be easily gotten rid of with some wallpaper stripper and a sponge.
Steaming off wallpaper using a rented steamer apparatus is a common wallpaper removal technique, but it can damage older walls that are constructed with paper-faced wallboards.
Instead, consider using a chemical agent combined with hot water. After allowing it to soak on walls that have been perforated using a "Paper Tiger" tool, wallpaper and glue should come off easily, leaving a surface that can be lightly sanded before being re-papered or painted.
