One, Can plywood be directly pasted with wallpaper?
No.
Applying wallpaper directly onto wood panels is not recommended because the wood will absorb moisture from the air, resulting in a higher moisture content than the wall itself. This trapped moisture can lead to mold growth and discoloration, ultimately causing the wallpaper to detach.
To ensure proper wallpaper application, the substrate requires specific characteristics: it must be smooth and maintain its stability over time. Drywall does not meet these requirements.
Two. How to apply wallpaper to plywood
Method 1: First, attach a layer of gypsum board or plywood to the wooden panel, then apply a base coat. This helps to isolate the moisture from the wallpaper adhesive, preventing cracking and bulging. Then, apply the wallpaper.
Method 2: After attaching the gypsum board to the wood panel, apply putty powder to achieve a smooth finish and then apply wallpaper.
Additionally, it is important to note that using particleboard directly with wallpaper is not recommended because the two materials have different shrinkage coefficients. Particleboard tends to shrink and deform more than wallpaper, which can lead to cracking or bubbling in the wallpaper due to the moisture in the wallpaper adhesive. To avoid this issue, it is necessary to use particleboard with the same moisture content before applying wallpaper.
