Walls should be as smooth as possible before applying peel-and-stick wallpaper. Although you technically can apply wallpaper on textured walls, the peel-and-stick variety won’t last long without a clean, smooth surface for the adhesive to stick to. If you have textured walls, consult a pro about removing the textured finish before moving forward with wallpaper.

Because replacing pool tiles requires fully draining your pool, it’s a great opportunity to complete other projects. You may want to replace your pool’s vinyl liner or repair cracks. You might also replace your swimming pool heater or even take on the cost of resurfacing your pool. Resurfacing, although relatively costly, can help prolong the lifespan of your pool.

No, you don’t need to apply paint primer to your wall before hanging paintable wallpaper. Manufacturers design paintable wallpaper so that the paint will adhere effectively, so primer isn’t necessary. Plus, even if you opt for a light shade of paint, you won’t have to worry about the shade underneath showing through because you are painting on a light, white surface.

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.
