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.

Textured or patterned vinyl wallpaper designs are the best option for hiding imperfections. Embossed designs or faux finishes like brick, wood, or linen textures are especially effective at camouflaging dents, cracks, or uneven surfaces. Avoid smooth, shiny finishes, as they can highlight flaws rather than conceal them. 

The pros of wallpaper include its durability and longer lifespan than paint, as well as its versatility. The durability can translate to lower long-term costs for upkeep and replacement, and the versatility means you have more options for customizing rooms in your home. Some downsides include that it’s difficult to remove, it’s not ideal for rooms or areas exposed to high moisture content or sun exposure, and it’s tricky to install. A professional wallpaper hanger can help mitigate these issues, though, by installing it properly and in areas suitable for wallpaper.

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.
