Applying new decor to textured walls presents a unique set of challenges, and wallpaper is often the first material to question. The short answer is yes, you can put wallpaper on textured walls, but success hinges entirely on the preparation method and the type of wallpaper you choose. Without the right approach, the uneven surface can cause peeling, bubbling, and an uneven finish that detracts from the aesthetic.
Understanding the Challenges of Textured Surfaces
The primary obstacle when dealing with textured walls is adhesion. Smooth surfaces allow wallpaper paste to create uniform contact, but bumps and ridges create gaps. If the adhesive cannot reach these high points, the bond weakens significantly, leading to the wallpaper detaching over time. Furthermore, any dirt or dust lodged in the texture acts as a barrier, preventing a secure seal and causing the installation to fail prematurely.
Surface Preparation is Non-Negotiable
Skipping preparation is the fastest way to ruin a wallpaper project on a textured wall. You must treat the surface as if it were brand new drywall. This involves deep cleaning to remove dust, and lightly sanding high points to reduce the severity of the texture. The goal is not to make the wall perfectly smooth, but to minimize sharp peaks that could puncture the paper or create weak spots in the adhesive bond.
Choosing the Right Wallpaper material
Not all wallpapers are created equal, and the material you select dictates whether the project is feasible. Standard paper-backed wallpaper is too fragile and will not conform to irregular surfaces without tearing. Instead, you should look for products specifically designed to handle imperfections.
Vinyl Wallpaper and Textured Walls
Vinyl wallpaper is the most reliable choice for this application due to its durability and slight flexibility. The vinyl coating allows the material to stretch slightly as it adheres, helping it to bridge minor gaps and bumps. Additionally, vinyl is washable, making it a practical choice for high-traffic areas where cleaning might be necessary after installation.
| Wallpaper Type | Suitability for Texture | Best Use Case |
|---|---|---|
| Vinyl | High | Hiding imperfections and high moisture areas |
| Textured Wallpaper | Medium | Coexisting with existing texture to add depth |
| Grasscloth/Non-Woven | Low | Smooth surfaces only |
Application Techniques for Success
Using the correct adhesive is just as important as the wallpaper itself. Standard pastes may not provide the grab necessary for heavy materials to cling to a rough surface. A premixed adhesive specifically formulated for heavy-walls or a high-quality primer-sealant is essential to lock down the texture and provide a uniform bonding layer.
Installation Tips to Avoid Trapping Air
When hanging the paper, work slowly and methodically to avoid trapping air bubbles between the wall and the backing. Because the surface is uneven, it is easy to create pockets of air that look like bubbles but are actually gaps of empty space. Using a smoothing brush to press the material into the texture helps ensure the glue reaches the substrate beneath the high points of the wall.
Alternative Solutions and Final Considerations
If the texture is extreme, such as heavy knockdown or popcorn ceilings, wallpaper might not be the best solution. In these cases, painting the walls with a durable matte finish often provides a more seamless look. However, if you are set on the pattern and dimension wallpaper offers, consider using large mural panels. These cover vast areas of wall space, minimizing the number of seams where the texture can cause the material to pop loose.
