Can You Put Wallpaper Over Shiplap? Tips & Tricks

The short answer is yes, you can absolutely put wallpaper over shiplap, but success hinges on treating the project with the same diligence as a standard wall renovation. Shiplap, with its inherent texture and potential for unevenness, presents unique challenges that require specific preparation techniques to ensure the wallpaper adheres properly and the final look is smooth and professional. Rushing this process often leads to poor results, so patience is key.

Assessing Your Shiplap for Wallpaper

Before selecting a wallpaper, you must evaluate the condition and installation method of your shiplap. If the boards are securely fastened to the wall studs and the surface is stable, you are in good shape. However, if the boards are loose or wobbly, they must be fixed immediately, as this movement will inevitably cause the wallpaper to crease or tear. You also need to consider the depth of the groove between boards; a deep shadow gap will create a prominent seam in the finished wallpaper, which may require special trimming or alignment strategies.

Surface Preparation is Non-Negotiable

Preparation is the most critical step in this process. Wallpaper paste needs a clean, non-porous, and rigid surface to bond effectively. Shiplap is porous and dusty, so it requires a specific regimen:

• Thoroughly clean the surface to remove any dirt, dust, or oil residue.
• Lightly sand the entire surface to smooth out splinters and create a uniform texture.
• Apply a bonding agent or primer specifically designed for new drywall or raw wood to seal the pores and create a stable base.

Skipping these steps risks the wallpaper peeling away from the gaps in the shiplap.

Choosing the Right Wallpaper

Not all wallpapers are created equal when it comes to installation over uneven surfaces. You should generally avoid ultra-thin, non-woven papers that offer little forgiveness. Instead, look for quality materials that provide durability and structure.

Pattern Repeat Consideration

If you are using a patterned wallpaper, the shiplap groove can disrupt the alignment. You will likely need to order a "drop match" pattern, which may require significantly more wallpaper than a straight match. Factor this into your budget and planning to avoid running out mid-installation.

The Installation Process

Applying wallpaper over shiplap requires a meticulous technique. You cannot rely on the paste activating the adhesive on the back of the paper alone; you must "backroll." After positioning the paper, use a wallpaper smoother to press the material firmly into the grooves, expelling air pockets. Then, apply a clean sponge with water to the surface of the wallpaper to ensure the paste penetrates the fibers and creates a bond with the shiplap beneath.

Trimming the Edges

Where the wallpaper meets the ceiling or baseboard, the thickness of the shiplap board can create a bump that prevents a clean edge. Use a sharp utility knife to slice the wallpaper slightly above the surface and then tuck the edge down behind the trim. This creates a crisp, finished line that hides the dimensional nature of the shiplap.

Potential Challenges and Solutions

Even with the best preparation, you might encounter the "ghosting" effect, where the lines of the shiplap are faintly visible through the wallpaper. This is usually due to inconsistent adhesion in the grooves. If this occurs, you can usually correct it by applying more paste to the affected area and using the smoother to push the paper down. Additionally, if you plan to paint the walls afterward, sealing the seams with joint compound before applying the wallpaper can create a flatter canvas.

Long-Term Maintenance

Once installed, wallpaper over shiplap behaves like standard wallpaper, but the wood content means it can be more susceptible to moisture damage in high-humidity areas like bathrooms. Ensure the bathroom has proper ventilation, and avoid using steam cleaners on the surface. With proper care, this design choice offers a unique blend of rustic charm and contemporary style that can elevate the character of any room.
