Yes, wallpaper can often be removed from plaster walls. The main challenge is protecting the plaster while loosening the paper and adhesive. Plaster may be strong and durable, but cracks, loose areas, prior repairs, or moisture damage can make it vulnerable. The wallpaper itself matters, too: a removable top layer behaves differently from older paper that is firmly bonded. Check both the wall and the covering before choosing a removal method.
Check the Plaster First
Inspect the walls for cracks, bubbling, soft spots, flaking paint, or sections that sound hollow when tapped. Pay extra attention to corners, ceilings, areas around windows, and places where leaks may have occurred. Wallpaper can conceal these problems, so a wall that looks smooth may still have weak or damaged plaster underneath.
Test a small, inconspicuous area before treating the whole room. If the plaster crumbles, separates from the lath, or pulls away with the paper, stop. More moisture or force could enlarge the damage. Repair loose plaster first, or ask a qualified professional to assess the wall and recommend a safe approach.
Identify the Wallpaper Type
Some wallpaper has a peelable surface that lifts away while leaving a backing layer behind. That backing may need to be dampened and removed separately. Strippable paper may come off in larger sections, while older or heavily pasted wallpaper can resist peeling and require careful work to soften the adhesive.
Vinyl-coated and other moisture-resistant papers may not let water reach the paste easily. Scoring can help, but aggressive tools can cut into plaster or the wall surface. Start with the least invasive method that works, and test any removal solution in a small area. Avoid soaking the wall, especially if the plaster is already cracked or weak.
Choose a Controlled Method
Protect floors and nearby surfaces, then work in small sections. Lift an edge with a broad, flexible scraper rather than a sharp blade. Apply only enough remover or warm water to loosen the adhesive, and give it time to work before peeling. If the paper does not release with light pressure, reassess instead of scraping harder.
Steam can loosen stubborn paste, but prolonged heat and moisture may damage plaster or loosen paint and previous repairs. Use steam cautiously, keep it moving, and test first. Do not assume that a method that worked on drywall is safe for plaster; the wall’s age, finish, and condition all affect the risk.
Plan for Repairs and Cleanup
Even careful removal may reveal small holes, old patches, stains, or adhesive residue. Once the wallpaper is off, let the wall dry fully before assessing it. Remove remaining paste gently; residue can interfere with primer and paint. If the surface becomes dusty, soft, or uneven, pause and address the underlying issue before applying a new finish.
A small test area can help you judge the time and care the full project will require. If wallpaper is layered, the plaster is deteriorating, or the paper will not release without force, a wallpaper removal specialist can evaluate the wall and handle the work with appropriate precautions.
Wallpaper can be removed from plaster, but the safest plan depends on the wall’s condition and the paper’s construction. Inspect carefully, test a small area, and use the gentlest effective method.
