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.

Your peel-and-stick wallpaper can fall off for multiple reasons, including high humidity levels, extreme temperature changes, poor installation, and even the wall surface. Textured walls can prevent the adhesive from fully sticking to the wall, making it more likely for the wallpaper to peel off. Low-quality wallpapers with weaker adhesives are also more likely to fall off prematurely.

One of the biggest downsides to peel-and-stick wallpaper is that it doesn't last as long as traditional wallpaper. Its lifespan depends on several factors, including the quality of the paper, proper wall preparation and application, and the room's conditions. As a general rule, peel-and-stick wallpaper can last for at least five years, but this can vary significantly. Budget products may only last about 3 years, while higher-quality products can stay up for 7 years or more in ideal conditions. Factors that can shorten its lifespan include high humidity (such as in a bathroom), dirty walls, and low-quality paper. If used on flooring, expect it to last only 1 to 3 years unless sealed. However, the shorter lifespan can be seen as a positive, making it a great choice for people who enjoy switching up their interiors more frequently.

To determine how many rolls of peel-and-stick wallpaper you need, measure the square footage of the walls you’re covering and divide that by the square footage that each roll covers. Add 10% to 20% of your total square footage to account for pattern matching or damage while installing.
