Can You Put Shiplap Over Wallpaper? (DIY Guide)

The short answer to the question, can you put shiplap over wallpaper, is a definitive yes. However, success is not as simple as nailing boards directly over a floral pattern and calling it a day. This method has become a popular design hack for homeowners who want the textured, rustic charm of shiplap without the commitment of removing existing wallpaper. With the right preparation and technique, you can transform a dated room into a stylish sanctuary that feels both curated and cozy.

Assessing Your Current Wallpaper

Before you grab your drill, you must evaluate the condition of your existing wallpaper. The integrity of the current surface is the most critical factor in determining if your project will succeed or end in disaster. If the wallpaper is peeling, bubbling, or loose in any spots, you must remove it entirely before proceeding. Covering unstable wallpaper will only trap the problem beneath the boards, ensuring that the issues will eventually show through or worsen.

Next, consider the texture and thickness of the wallpaper. Glossy or heavily embossed surfaces will create a ripple effect in the shiplap, making the bumps and ridges visible from the new layer. While this isn’t necessarily a dealbreaker, it requires extra planning to ensure a smooth final result. You are essentially creating a flat substrate for your shiplap to adhere to, so the smoother the wallpaper, the better the outcome.

The Adhesive Factor

Adhesive is the unsung hero of this project. You cannot rely on the existing wallpaper adhesive to hold the weight of the shiplap, nor can you rely on the friction of the boards alone. You will need a construction adhesive, such as Liquid Nails or a similar heavy-duty product, to create a secure bond between the old paper and the new wood. Skipping this step is a recipe for boards detaching from the wall over time.

Additionally, consider the weight of the material you are installing. Real wood shiplap is heavy, and you need to ensure that the wall can handle the load. If you are using a lightweight PVC or composite shiplap, the risk is lower, but the principle remains the same: a strong bond is non-negotiable for longevity.

Preparation and Installation Process

If your wallpaper passes the integrity test, the process moves forward efficiently. Start by cleaning the walls thoroughly to remove any dust or grease that might prevent the adhesive from bonding. Measure your walls carefully and plan your layout. Beginning in the center of the wall rather than forcing the boards to fit awkwardly around corners is often a smarter approach to achieving a polished look.

As you install, pay close attention to the vertical joints. One of the main advantages of skipping wallpaper removal is that the existing paper acts as a guide, ensuring that your seams fall in random places. This creates a more natural and visually appealing pattern compared to the rigid grid you would create if you removed the wallpaper first. Use a level constantly to ensure your rows stay perfectly straight.

Tools and Materials You Will Need

Successful installation requires the right arsenal of tools. You will need a reliable tape measure, a level, a utility knife, a drill, and appropriate fasteners. While some installers attempt to use a brad nailer to secure the shiplap directly over the wallpaper, this often does not provide enough holding power. Screws or nails that penetrate deep into the wall studs are the best method for ensuring the boards remain rigid and secure for years to come.

Addressing Potential Challenges

Even with the best preparation, you might encounter minor obstacles. Outlets and switches present the biggest hurdle. You will need to turn off the power, carefully remove the faceplates, and decide whether to install the shiplap around the box or cut precise holes to sit flush. Using a sharp utility knife or a oscillating tool makes cutting through the wallpaper and wood cleanly much easier.

Another challenge is the transition to door frames and window casings. You want the shiplap to look like it is part of the wall, not a floating piece added on top. Careful scribing and trimming will allow the wood to follow the contours of the frame seamlessly. This attention to detail is what separates a good DIY project from a professional-looking renovation.

The Benefits of This Approach

Choosing to layer shiplap over wallpaper offers distinct benefits that go beyond just saving time. It adds an extra layer of insulation and sound dampening to the room, thanks to the air gap created by the existing paper. This can slightly improve the energy efficiency of the space and make the room feel warmer and more inviting.

Furthermore, this technique allows for greater design flexibility. If you ever decide to remove the shiplap in the future, the wallpaper (if it remained undamaged) could potentially be preserved underneath. It provides a unique texture that paint alone cannot replicate, giving your walls depth and character that solid walls lack.

Final Considerations and Verdict

Ultimately, putting shiplap over wallpaper is a practical and stylish solution for updating a room. It is a testament to smart renovation, prioritizing efficiency without sacrificing aesthetic appeal. As long as you respect the need for proper adhesion and surface preparation, you can achieve a high-end look that hides the old decor under a veil of modern rustic charm.

Before you finish, inspect the work from different angles and lighting. Look for any spots where the boards might be lifting or where the seam lines might be awkward. Making minor adjustments during the installation phase ensures that the final result is not only structurally sound but visually perfect. When done correctly, this project delivers exactly the look you envision.
