Can You Paint Over Wallpaper?
QUICK ANSWER
Yes, you can paint over wallpaper if the wallpaper is well-adhered, smooth, and not peeling. Prime with an oil-based or shellac primer first to seal the paper and prevent moisture from loosening the adhesive underneath. Remove any wallpaper that is damaged or lifting.
Painting over wallpaper is the shortcut homeowners take when wallpaper removal seems like too much work. Sometimes it works fine and looks great for years. Other times it peels off within months and creates a worse mess than starting from scratch. The difference is whether the wallpaper underneath is sound and whether you prep correctly. Here is when painting over works and when removal is the right call.
Should you paint over wallpaper or remove it?
Remove wallpaper if it is peeling, lifting at seams, has bubbles, or shows water damage. Paint over wallpaper if it is fully adhered, smooth, and intact. The risk with painting over: water in the paint can reactivate the wallpaper adhesive and cause the wallpaper to bubble or peel. This is why oil-based or shellac primer (not water-based) is essential as the first coat. If only a small section is damaged, you can sometimes remove just that section, patch with drywall compound, and paint over the rest.
How do you prep wallpaper for painting?
Clean the wallpaper thoroughly with a damp cloth to remove dust and grime. Let it dry completely. Glue down any small lifted edges or seams with wallpaper paste or seam sealer. Fill any tears, holes, or damaged areas with drywall compound, let dry, then sand smooth. Apply an oil-based primer (Zinsser Cover Stain) or shellac primer (Zinsser BIN) to the entire wallpaper surface; these do not contain water that would soak through and loosen the wallpaper. Let primer dry 24 hours, then paint with latex.
What if the wallpaper is textured or peeling?
Heavily textured wallpaper (raised patterns, anaglypta, embossed prints) shows through paint and may need to be removed or skim-coated with drywall compound before painting. Light texture can sometimes be smoothed with sanding and a coat of high-build primer. If the wallpaper is peeling in any sections, do not paint over those sections; the paint will not fix the peeling and the affected area will look worse. Remove peeling sections completely or remove the entire wallpaper.
What about wallpaper paste residue?
If you have removed wallpaper but adhesive residue remains on the wall, do not paint directly over it. The residue causes the new paint to bubble and peel. Wash the wall with warm soapy water and a sponge to remove as much paste as possible. For stubborn residue, use a wallpaper paste remover (DIF, Zinsser DIF) per the label. Let the wall dry completely. Sand any rough spots smooth. Then prime with an oil-based or shellac primer before painting. This step is non-negotiable for paint to bond properly.
Painting over wallpaper works if the wallpaper is intact and well-adhered, you prime with an oil-based or shellac primer (not water-based), and you address any damaged sections first. When the wallpaper is peeling, bubbling, or heavily textured, removal is the better long-term answer. The extra work of removing the wallpaper now prevents the bigger problem of paint failure later.
