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.

We don’t recommend wallpapering over older paper. That’s because creating layers of glue can invite bubbling or excess moisture on the wall’s surface. You should also prime your wall before applying wallpaper and smooth the wall as much as you can, and another layer of wallpaper complicates this process.

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.

Having dated, peeling, or otherwise damaged wallpaper can decrease the value of your property, so removing that before listing your house is nearly always a good idea; however, since wallpaper tends to be a personal style choice, potential buyers may or may not love your aesthetic as much as you do.

Love the look of wallpaper but want to consider property value as well? Stick with something that is easy to change. If you are thinking of selling soon, make sure your wallpaper hanging is on-point and looks professional with no crooked seams, evenly matched patterns, and minimal bubbling or other imperfections.
