Can I hang wallpaper over wood paneling?

Answer: In most cases
Explanation: Wallpaper can often be installed over wood paneling, but the surface usually needs proper prep first. Paneling grooves, texture, and glossy finishes can show through or affect adhesion if the wall is not prepared. In most cases, the paneling should be cleaned, sanded if needed, grooves filled, and primed to create a smoother surface. If the paneling is warped, loose, or heavily textured, more prep may be required before wallpapering.
