How To Prep Walls for Peel and Stick Wallpaper

There’s a DIY revolution underway in home-improvement, and peel and stick wallpaper is leading the way. High-quality peel and stick wallpaper is durable, easy to apply, and doesn’t leave a mess behind. It also comes in a wide array of textures, patterns, and colors. You can even buy peel and stick wall-murals or faux grasscloth for an upscale look. 

Peel and stick wallpaper has an adhesive backing, so you can simply remove the backing and stick it to the wall. But even though it’s known for its ease of application, you still need to prep your walls and measure carefully for the best results. In this step-by-step guide, we’ll explain exactly how to prep your walls for peel and stick wallpaper that looks great and stands the test of time.

Why Wall Prep Matters for Wallpaper Application

Peel and stick wallpaper uses a built-in adhesive backing to stick to your walls. If your surfaces are dusty, greasy, textured, or damaged, the wallpaper may end up peeling or bubbling over time.

Prepping your walls before applying peel and stick wallpaper helps ensure:

• Strong adhesion
• Bubble-free application
• Lasting results
• Smoother removal down the line

Mistakes To Avoid

Here are some common pitfalls you should avoid when installing peel and stick wallpaper:

• Rushing application: Always apply your wallpaper slowly, lining up each strip one at a time. Rushing through the process can lead to crinkling, distortion, and pattern misalignment.
• Measuring incorrectly: Knowing how to measure for wallpaper is essential when it comes to DIY. Be sure to double-check your measurements before you start. 
• Ignoring humidity: High humidity in rooms like bathrooms can damage certain wallpapers over time. Check to make sure your peel and stick wallpaper is moisture-resistant when working in these rooms. 
• Applying to textured walls: Textured surfaces like popcorn ceilings can seriously compromise adhesion. You should smooth out texture first to ensure longevity.
• Skipping cleaning: Dirt, grime, and oil can impact adhesion with peel and stick wallpaper. Wipe down and dry the wall before you hang your design.

Step-by-Step Instructions To Prep for Peel and Stick Wallpaper

1. Assess Wall Texture

Start by taking a close look at the condition of your walls. Peel and stick wallpaper tends to work best on smooth drywall, recently painted walls, or primed wood.

It’s generally best to avoid applying wallpaper directly to:

• Existing wallpaper
• Unpainted drywall
• Highly textured walls
• Brick or concrete

If you have a textured surface, consider sanding it down and repairing any damage prior to application.

2. Remove Fixtures and Hardware

Get rid of anything that will get in your way, including:

• Outlet plates
• Light switch covers
• Nails or screws
• Wall hooks
• Curtain rods

This gives you a clean, obstacle-free surface to work with.

3. Cover Floors and Furniture

Peel and stick wallpaper doesn’t leave a mess the way paint or paste-style wallpapers can. But it’s still a good idea to cover your floors and furnishings with drop cloths.

4. Clean the Walls

Grease, dust, and grime can lead to problems with adhesion. To avoid this, clean your walls before you begin applying the wallpaper. Mix a mild detergent in a bucket with warm—not hot—water. Apply the mixture using a sponge or microfiber cloth. Pay extra attention to corners, edges, and any visibly dusty areas.

When you’re finished, rinse your walls clean with plain, warm water and let the surfaces dry completely.

5. Repair Wall Imperfections

Cracks and holes in your wall may be visible through your design and cause the wallpaper to lift over time. Use spackle to fill in the damage, wait for it to dry, then gently sand until smooth. 

6. Prime the Wall (Optional)

You don’t need to use a separate primer before hanging peel and stick wallpaper, but it can be beneficial—particularly if you want to ensure long-lasting adhesion and prevent any wall damage down the line.

Here’s how to prime your walls before application:

• Choose a primer that’s suitable for peel and stick wallpaper.
• Apply a thin layer of primer with a roller or brush.
• Wait until the primer has completely dried before installing the wallpaper.

7. Try a Small Test Section

Before you commit to an all-over application, it’s a good idea to test your chosen pattern (and your application skills) on a small section of your walls. Try to choose an inconspicuous area to test, such as behind a piece of furniture or in a closet. This will give you a chance to practice your installation technique and see if you still love the design.

Tips for a Successful Application

Once you’ve carefully prepped your walls and tested a small section, you’re ready to start applying the wallpaper. Here are a few tips to help you get professional, long-lasting results:

• Measure twice, cut once: Always measure your walls and cut your wallpaper pieces carefully. Leave an extra section at the top and bottom so you can trim any excess.
• Use a plumb line or level: For a straight application, mark a vertical guideline using a level or plumb line. Make sure your patterns align with each section.
• Apply slowly: With each piece, start at the top of the wall and peel the backing off gradually. Use a smoothing tool or plastic scraper to eliminate bubbles as you work.
• Trim any excess carefully: Use a sharp blade or utility knife to trim excess wallpaper from corners, edges, and around fixtures.
• Avoid stretching: Peel and stick wallpaper can become distorted, misaligned, or shrunken if you stretch it too hard during application. Avoid tugging and handle it carefully.
