Please wash the surface with a wet sponge or cloth to clean it. When you wipe the wallpaper for the first time, paint residue may leak out due to the printing process. However, this does not affect the natural colors of the design or the quality of the material.
Always wipe the wallpaper vertically. Never use a tape mask on the surface of the wallpaper. We recommend a protective varnish for better protection of wallcovering, especially in bathrooms, kitchens, and other humid environments.
