Yes, you can apply peel-and-stick wallpaper over wood paneling, but it requires significant preparation for a good result. Peel-and-stick wallpaper has a weaker adhesive than traditional wallpaper and works best on smooth, non-textured surfaces like painted or primed drywall. Because wood paneling is often textured with grooves, any flaws in the underlying surface will likely be visible after application. To prepare the paneling, you must ensure the surface is free of cracks, holes, and protrusions by filling any indentations and sanding rough spots to create a smooth surface. An alternative is to remove the paneling and apply the wallpaper directly to the underlying drywall or plaster, provided it is in good condition.

Ideally, you want to ask the wallpaper installers you’re considering for examples of past work, and references you can call. These will prove that the installer can handle your job, make your room look professional, and will also give you some insight into the kind of customer service you can expect. Before you start calling companies, you might want to narrow down your options by finding installers with mostly positive reviews online.

Peel-and-stick wallpaper is designed to be removed without damaging walls, making it a good choice for renters or temporary design changes. However, damage to paint or drywall can occur under certain conditions. To prevent issues, the wall surface must be properly prepared before application—it should be clean, smooth, dry, and correctly primed or painted. Applying wallpaper to a freshly painted surface can cause the paint to peel off during removal. Additionally, removing the wallpaper too quickly or aggressively can also cause damage. For best results, always follow the manufacturer's instructions for both application and removal.

Deciding between a lighter or darker accent wall depends on the effect you’re going for. Choosing an accent wall in a lighter color will make a room feel brighter and more spacious and complement rooms with less natural light. A darker accent wall will add drama and depth to a room and help make larger rooms feel more cozy and intimate.
