It is one of the most common questions we receive at Mass Pro Painting: “Can I just paint over this old wallpaper?” Whether you’ve just moved into a new home with dated patterns or you’re looking for a quick refresh, the prospect of stripping wallpaper can feel overwhelming. While painting over wallpaper is a tempting shortcut, it is a process that requires precision and the right materials to avoid a costly disaster.
In the professional painting industry, we generally view painting over wallpaper as a secondary option. However, when the wallpaper is structurally sound and the proper steps are followed, it can result in a beautiful, updated space. This guide explains the “how” and “when” of painting over wallpaper like a pro.
Quick Answer: It Can Work, but It’s Not Always Recommended
Technically, you can paint over wallpaper, but it is not a “standard” practice for long-term durability. Success depends entirely on the condition of the paper and the quality of the original installation.
Situations Where Painting Is Acceptable
Painting over wallpaper is generally acceptable if:
- The wallpaper is firmly bonded to the wall with no peeling edges or bubbles.
- The wallpaper is applied over plaster walls in older homes where removal might cause the plaster to crumble.
- You are looking for a temporary aesthetic fix and understand that the wallpaper may be harder to remove in the future.
Common Failure Points
The most frequent cause of failure is the moisture in the paint. Standard water-based paints can soak into the wallpaper, reactivating the old adhesive and causing the paper to bubble, sag, or peel away from the wall. Additionally, if the wallpaper has a prominent texture or visible seams, those imperfections will be even more noticeable once a fresh coat of paint is applied.
How to Prepare Wallpaper for Painting
Preparation is the most critical stage. If you skip these steps, the paint will likely fail within months.
Cleaning and Degreasing
Wallpaper is a magnet for dust, kitchen grease, and finger oils. Paint will not bond to a dirty surface. Use a mild solution of TSP (Trisodium Phosphate) and water to wipe down the walls. Ensure the walls are completely dry—usually 24 hours—before moving to the next step.
Sealing Seams and Edges
Inspect every inch of the seams and edges. If any part of the paper is lifting, it must be glued back down using a specialized seam adhesive. If there are small tears or holes, use a thin layer of joint compound to level the surface, then sand it smooth so the transition is invisible.
Priming Correctly (The Non-Negotiable Step)
Do not use water-based primer. You must use an oil-based or shellac-based primer (such as KILZ Original or Zinsser B-I-N).
- The Reason: Oil-based primers create a barrier that prevents the water in your paint from reaching the wallpaper glue. They also seal in the dyes and patterns of the wallpaper so they don’t “bleed” through your new paint color.
Best Paint and Primer Choices
In the US market, specific products are designed to handle the challenges of non-porous surfaces like wallpaper.
Stain-Blocking Primers
As mentioned, oil-based or shellac-based primers are mandatory. These are often referred to as “stain-blockers” because they prevent the inks in the wallpaper from reacting with the new paint. Without this, a floral pattern can “ghost” through even three or four coats of premium latex paint.
Paint Finishes That Hide Imperfections
When painting over wallpaper, avoid high-gloss or semi-gloss finishes. These sheens reflect light and will highlight every seam and texture of the underlying paper. Instead, opt for a Flat, Matte, or Eggshell finish. These low-lustre paints diffuse light, helping to mask the presence of the wallpaper underneath.
When Wallpaper Should Be Removed First
Sometimes, the best advice we can give as professionals is to stop and strip the paper.
Vinyl Wallpaper
Vinyl is essentially plastic. It is designed to be waterproof and “wipe-clean,” which makes it incredibly difficult for paint to bond to it. Even with a high-adhesion primer, paint on vinyl is prone to scratching and peeling.
Loose or Textured Wallpaper
If the wallpaper is already peeling at the corners or has a raised, embossed texture (like flocking or heavy floral relief), paint will not fix it. The texture will remain visible, and the added weight of the paint will only accelerate the peeling.
FAQs
Will wallpaper seams show through paint?
Yes, they often do. Even with careful priming, the slight ridge where two pieces of wallpaper meet can create a visible line. To minimize this, pros often “skim” the seams with a tiny amount of joint compound and sand them flat before priming.
What primer should be used?
Only use oil-based or shellac-based primers. Water-based (latex) primers will reactivate the wallpaper adhesive and cause the paper to lift and bubble.
Is removal always better?
Yes. From a professional standpoint, removing the wallpaper, cleaning the glue, and repairing the drywall is the only way to guarantee a flawless, long-lasting finish. Painting over wallpaper is a shortcut that carries inherent risks.
