Once again, contact with moisture is the culprit here, though water-resistant varieties of wallpaper are less likely to become wet and develop mold. Using a high-quality exhaust fan or dehumidifier and leaving the doors or windows cracked after bathing will keep this issue at bay. 

While peel-and-stick wallpapers require no time to cure, the adhesives for other types of papers will take a day or two to dry and up to three weeks to fully cure. The differences are the type of paper, the type of adhesive, and the humidity and temperature in the space. 

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.

It is less costly to paint than wallpaper when you only consider the upfront cost. Wallpaper costs $320 to $820 when applied by a pro, while paint only costs $200 to $700 per room. However, when comparing wallpaper versus paint, consider the long-term as well. Wallpaper can save you money over time since it has a much longer life span than paint.
