Can You Remove Wallpaper Without Damaging Plaster?
Removing wallpaper can be a messy and time-consuming task, and the biggest concern for many DIYers is whether they can do it without damaging the plaster underneath. The good news is that it’s often possible, but it requires careful preparation and the right techniques.
Factors influencing the risk of plaster damage:
Type of wallpaper: Modern wallpaper is usually designed to be strippable, meaning the top layer peels off easily, leaving a backing paper that can be removed with water and a scoring tool. Older wallpaper may be more difficult to remove, especially if it has been painted over or applied with strong adhesive. This type may require more aggressive methods that increase the risk of plaster damage.
Condition of the plaster: Sound and stable plaster in good condition is less likely to be damaged during wallpaper removal. Weak or damaged plaster is more susceptible to damage, especially if it’s already cracked, loose, or crumbling.
Removal method used: Gentle methods like using a scoring tool and warm water are less likely to cause damage. Harsh chemicals or excessive force can increase the risk of damaging the plaster.
Methods for removing wallpaper without damaging plaster:
Preparation: Protect the surrounding area by covering floors and furniture with dust sheets. Test a small area by trying to remove a small section of wallpaper in an inconspicuous area to assess its type and condition. This will help you choose the best removal method.
Scoring the wallpaper: Use a scoring tool or wallpaper scraper to create small perforations in the wallpaper. This allows steam or water to penetrate and loosen the adhesive.
Applying steam or water: A wallpaper steamer can be very effective in loosening the adhesive, but use it cautiously to avoid overheating the plaster. Alternatively, mix warm water with a wallpaper removal solution or fabric softener. Apply it to the wallpaper with a sponge or spray bottle, allowing it to soak in.
Stripping the wallpaper: Start from a seam or corner and gently peel the wallpaper away from the wall using a scraper or putty knife. Work in small sections and don’t try to remove large sections at once, as this can pull off chunks of plaster.
Removing any remaining adhesive: Use a sponge and warm water to wash off any residual adhesive.
Tips to minimise plaster damage:
Be patient: Don’t rush the process. Allow sufficient time for the steam or water to penetrate the wallpaper.
Use gentle pressure: Avoid excessive force when stripping the wallpaper.
Avoid harsh chemicals: Strong chemicals can damage the plaster.
If the wallpaper is resistant, try a different method: If one method isn’t working, don’t resort to excessive force. Try a different approach, such as using a steamer or a different removal solution.
If you encounter resistance, stop and reassess: If you feel significant resistance, it’s possible the wallpaper is pulling away the plaster. Stop and try a different technique or seek professional help.
Removing wallpaper without damaging plaster is achievable with the right approach. By carefully assessing the wallpaper type, using appropriate removal methods, and exercising patience and gentle pressure, you can successfully strip wallpaper while preserving the integrity of your walls. However, if you’re dealing with delicate plaster or encounter difficulties, don’t hesitate to consult a professional decorator for assistance.
