Can You Wallpaper Over Wallpaper?

Can You Wallpaper Over Wallpaper?

When it comes to giving your space a fresh new look, wallpaper is a fast and effective way to transform a room. But what happens if your walls are already covered? Can you wallpaper over wallpaper without making a mess or risking damage later?

The short answer: sometimes you can — but that doesn’t mean you always should. The decision depends on the condition of your existing wallpaper, the type of material it’s made from, and your long-term design goals. In this guide, we’ll explore when it’s safe, when it’s not, and how to prepare your walls so the results look flawless.

Is It OK to Wallpaper Over Wallpaper?

If you’re wondering can you put wallpaper over wallpaper, the answer is: yes, under the right circumstances. This is most common when the existing wallpaper is in excellent condition — smooth, clean, and firmly adhered to the wall.

However, there are trade-offs. Even if you manage to achieve a neat finish, any bumps, seams, or raised textures in the original wallpaper can show through the new layer. Additionally, patterns or dark colors underneath may still be faintly visible, especially if you choose a lighter or thinner new wallpaper.

So, while it can be done, you’ll need to weigh convenience against the risk of imperfections.

When It’s Acceptable to Cover Wallpaper with Wallpaper

There are a few situations where can you cover wallpaper with wallpaper becomes a practical solution:

  • Only one existing layer — Multiple layers add bulk, create unevenness, and make adhesion more difficult.
  • Smooth and matte finish — Matte wallpaper accepts new adhesive more readily than glossy or vinyl finishes.
  • No damage or moisture issues — Peeling, bubbling, or stains are red flags.
  • Secure adhesion — The current wallpaper should be tight to the wall with no loose edges.

If your project meets all these criteria, you can proceed — but preparation is still key.

When You Should Avoid It

Even if you’re tempted to skip the removal process, there are cases where it’s simply not worth the risk:

  • The existing wallpaper is vinyl-coated or foil-based. In this case, can you wallpaper over vinyl wallpaper? Technically possible, but adhesion is often poor without extensive prep.
  • There are signs of water damage, mold, or mildew — these issues will only worsen if sealed under new material.
  • More than one layer already exists — this creates a lumpy surface and makes future removal even harder.
  • The surface is wood paneling, unprimed drywall, or another material prone to absorbing moisture.

In these cases, removal remains the best long-term solution.

Using Peel and Stick Over Wallpaper

Many DIYers ask whether they can apply modern self-adhesive options on top of existing walls. The question can you put peel and stick wallpaper over wallpaper or peel and stick wallpaper over wallpaper has a tricky answer: manufacturers generally recommend applying peel-and-stick to smooth, painted, and primed walls only.

While it’s physically possible to apply it over existing wallpaper, the adhesion may not be as reliable, especially if the surface is textured or glossy. Removal later could also damage both wallpaper layers, making the job more difficult.

Similarly, for renters and temporary makeovers, the question can you put removable wallpaper over wallpaper comes up often. The same rules apply — smooth, matte surfaces are more likely to work, but performance can’t be guaranteed.

At Costa Cover, as a wallpaper manufacturer, we recommend applying peel-and-stick only to properly prepared, smooth, and painted walls for the best results. 

Preparing to Hang Wallpaper Over Existing Wallpaper

If you’ve decided to go ahead, learning how to hang wallpaper over existing wallpaper is essential for a professional result. Here’s the process:

  1. Clean Thoroughly – Remove dust, dirt, and grease with a mild cleaning solution.
  2. Secure Loose Areas – Glue down any lifted seams or corners.
  3. Repair Imperfections – Use a lightweight spackle or skim coat to smooth out uneven areas.
  4. Prime the Surface – Apply a wallpaper-friendly primer to improve adhesion and block potential stains from bleeding through.
  5. Choose the Right Wallpaper – Thicker, textured designs can help disguise minor flaws underneath.

Why Removal Is Better

While applying new wallpaper over old can save time, removal has clear advantages. It provides a fresh, smooth base, ensures better adhesion, and eliminates the risk of patterns or textures showing through.

If removal seems daunting, consider these steps:

  • Use a scoring tool and wallpaper remover solution.
  • Rent a steamer for stubborn adhesive.
  • Repair and prime the wall before applying new wallpaper.

A clean slate almost always delivers the most polished and durable finish.

Final Thoughts

So, is it ok to wallpaper over wallpaper? Yes — but only if the existing surface is in excellent shape and you’re prepared to accept possible imperfections. For peel-and-stick enthusiasts, be aware that performance is less predictable over old wallpaper, especially if it’s glossy or vinyl-coated.

When in doubt, take the time to strip, repair, and prime your walls. The extra effort at the start will reward you with a flawless, long-lasting result that you’ll enjoy for years.
