Can You Paint Over Wallpaper? (When to Do It, When to Remove It)

Published April 2026 - Joseph Assise III Painting & Wallpapering, Easton PA

It is one of the most common questions we get from homeowners across the Lehigh Valley: "Can I just paint over this wallpaper instead of removing it?" The honest answer is - sometimes yes, sometimes absolutely not. The difference comes down to the condition of the wallpaper, what is behind it, and how long you want the result to last.

This guide explains the situations where painting over wallpaper can be a reasonable choice, the situations where removal is the only path forward, and what the correct process looks like if you do decide to paint over it.

When Painting Over Wallpaper Can Work

There is a narrow set of conditions under which painting over existing wallpaper gives an acceptable result. All of these need to be true at the same time:

  • The wallpaper is fully bonded to the wall with no lifting seams, bubbles, or loose sections
  • There is only one layer of wallpaper (multiple layers compound every problem)
  • The wallpaper is not vinyl-coated (paint will not bond to vinyl surfaces reliably)
  • The underlying drywall or plaster is in good shape and was properly installed
  • You are not planning to sell the home soon - buyers and home inspectors often flag painted-over wallpaper as a future problem

Even when all of those conditions are met, painting over wallpaper is still a compromise. The seams will almost always show through the final topcoat to some degree. The texture of the wallpaper pattern will be visible under the paint. You are also making future removal significantly harder because paint seals the paper to the wall.

When You Must Remove the Wallpaper First

In our experience working on homes throughout Easton, Bethlehem, and Allentown, removal is the right call in most situations. You should always remove first if:

  • Any seams are lifting or the paper is bubbling away from the wall
  • There are multiple layers of old wallpaper stacked up
  • The paper is vinyl or vinyl-coated (paint adhesion will fail)
  • There is moisture damage, mold, or water staining behind the paper
  • You are updating the home for resale - real estate agents and buyers will notice
  • The room is a bathroom or kitchen where moisture is ongoing

Many older homes in Easton and the surrounding Lehigh Valley area were built in the 1960s through 1980s when wallpaper was standard in nearly every room. If your home is in that era, there is a good chance you have vinyl-coated paper, possibly applied directly over unprimed drywall. That combination is the worst-case scenario for painting over - the paint will not bond to the vinyl, and if you try to remove it later, the drywall facing tears away with it.

How to Paint Over Wallpaper Correctly

If removal is not an option and conditions are right, here is the proper process to minimize problems:

  1. Repair all lifting seams. Use seam repair adhesive or a small amount of vinyl-to-vinyl wallpaper adhesive. Smooth each seam flat and let it dry completely before moving on.
  2. Sand down raised seams. Use fine-grit sandpaper (150 to 180 grit) to knock down any seam ridges. Feather the edges so they blend into the surrounding surface.
  3. Prime with an oil-based primer. This is critical. A water-based primer can activate the wallpaper glue and cause the paper to bubble, loosen, or ripple. An oil-based primer like Zinsser Cover Stain seals everything without disturbing the adhesive. Apply a full, even coat and allow it to dry thoroughly - usually 8 to 12 hours.
  4. Skim-coat over seam lines if needed. If seams are still visible after the primer dries, apply a thin skim of joint compound over the seam lines, let dry, sand smooth, and re-prime those areas.
  5. Apply your topcoat with a roller. Use a 3/8-inch nap roller to apply paint evenly. Two coats with full drying time between them is the standard. Avoid saturating any single area with excess paint, which can reactivate adhesive in older paper.

The Long-Term Reality

Even when done correctly, painted-over wallpaper tends to show its seams more visibly over time as the house settles and humidity cycles through the seasons. Pennsylvania homes - especially the older stock in Easton's historic neighborhoods - go through significant seasonal humidity changes that expand and contract walls. That movement makes seams more visible over the years.

If you want a wall that looks truly painted - smooth, seamless, and fresh - wallpaper removal followed by proper skim coating and priming is the only way to get there. It costs more upfront. It takes more time. But the result lasts longer and looks significantly better.

Frequently Asked Questions

Will the wallpaper seams show through the paint?

In most cases, yes - at least somewhat. Seams can be minimized by sanding, skim coating, and using an oil-based primer, but they rarely disappear completely. Under raking light or once the paint dries fully, seam lines are often still visible. If a perfectly smooth, seamless wall is the goal, removal and skim coating is the path to get there.

What kind of primer do I use when painting over wallpaper?

Always use an oil-based primer - not a water-based latex primer. Water activates wallpaper adhesive, which causes the paper to bubble, ripple, and pull away from the wall. Zinsser Cover Stain is a reliable oil-based option. Apply it in a full even coat and give it 8 to 12 hours to cure before applying topcoat.

Can you paint over vinyl wallpaper?

Not reliably. Vinyl surfaces are designed to repel moisture, which means they also repel paint adhesion. Even with a bonding primer, paint over vinyl tends to peel within a year or two. If the wallpaper has a shiny or plastic feel to the surface, it is almost certainly vinyl-coated and should be removed before painting.

How hard is wallpaper removal if it has been painted over?

Significantly harder than removing unpainted wallpaper. Paint seals the paper's surface so scoring and steaming tools have a harder time penetrating. It also tends to come off in smaller pieces, and the drywall facing underneath is more likely to tear. In many cases, homes that have painted-over wallpaper end up needing skim coating or drywall repairs after removal - which adds cost and time.

Should I remove wallpaper before selling my home?

Yes, in nearly every case. Buyers notice wallpaper - and painted-over wallpaper even more so. Real estate agents in the Easton and Lehigh Valley market will often recommend removal as part of pre-sale prep because it photographs better, shows better during walkthroughs, and avoids objections during inspection. The investment in removal and fresh paint almost always returns more than it costs in a competitive market.
