No. If you overlap seams, the wallpaper will not come out flat. In addition to possibly throwing off your pattern match between rolls, overlapping seems necessary. If wallpaper is properly acclimated, and temperature and moisture conditions are optimal during installation, there is no reason to fear shrinkage as it dries.

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.

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.
