Peel-and-stick wallpaper is designed to be removed without damaging walls, making it a good choice for renters or temporary design changes. However, damage to paint or drywall can occur under certain conditions. To prevent issues, the wall surface must be properly prepared before application—it should be clean, smooth, dry, and correctly primed or painted. Applying wallpaper to a freshly painted surface can cause the paint to peel off during removal. Additionally, removing the wallpaper too quickly or aggressively can also cause damage. For best results, always follow the manufacturer's instructions for both application and removal.

When choosing materials for finishing basement walls, consider factors such as moisture resistance, durability, and fire resistance. Opt for materials specifically designed for basement environments, like moisture-resistant drywall or cement board. Insulation with vapor barriers can help regulate temperature and prevent condensation. Consider using mold-resistant paints or coatings. 

Research and consult with experts to select materials that are suitable for your specific basement conditions and intended use. Prioritize quality and compatibility to achieve long-lasting and aesthetically pleasing results.

No, you don’t always have to remove old wallpaper before applying a new layer. However, you should pull off the existing wallpaper if it’s cracked, peeling, or in poor condition. We’d also recommend against putting wallpaper over textured or dark-colored wallpaper because the old layer may be visible through the new one. In addition, if you try to hang new wallpaper over vinyl-coated wallpaper, the adhesive might not stick properly. 

Ideally, you want to ask the wallpaper installers you’re considering for examples of past work, and references you can call. These will prove that the installer can handle your job, make your room look professional, and will also give you some insight into the kind of customer service you can expect. Before you start calling companies, you might want to narrow down your options by finding installers with mostly positive reviews online.
