If you prefer peel-and-stick to traditional wallpaper, you can skip the priming process. Many manufacturers don't require an additional primer if you’re installing peel-and-stick wallpaper to painted walls. However, if you’re applying peel-and-stick wallpaper to unfinished drywall, you’ll need to apply a primer first.

In most cases, it is not recommended to wallpaper over existing wallpaper, as the success depends on the type of paper already on the wall. While you might be able to cover non-coated wallpaper, you should never apply new wallpaper over a vinyl-coated one, which is more common. Doing so can lead to poor adhesion, resulting in bubbles, imperfections, and peeling. It can also trap moisture, potentially causing hazardous mold growth between the layers.

Even if the existing wallpaper is suitable, experts recommend applying only one new layer. Adding multiple layers (more than two total) can cause significant adhesion problems, leading to warping and bubbling. For the best results, the recommended approach is to remove the old wallpaper and all paste residue before hanging the new paper. If you are unsure about your wallpaper type, consider consulting a professional.

Accent walls can feel out of place or distracting if not well designed. Accent walls that don’t fit in with a room’s style can feel jarring or overpowering. Some accent wall styles can also feel dated, but fortunately, it’s easier to update a single wall than an entire room.

Yes, many types of peel-and-stick wallpaper can be used in bathrooms, especially those made of vinyl or polyester. However, its success depends heavily on the level of moisture and ventilation. In bathrooms with good ventilation, such as those with fans, it can be a durable option. Peel-and-stick wallpaper may not adhere as well as traditional wallpaper in very humid conditions. For bathrooms that see a lot of moisture, like a kids' bathroom or a full bath with a steamy shower and poor ventilation, even high-quality peel-and-stick wallpaper is likely to peel over time.
