Infrastructure
If the wall or floor that you intend to beautify is clean and free of any covering, you can choose wallpaper and color. But if wallpaper has been used before, for re-installation, it is necessary to remove it with tools and chemicals, which is a very difficult task. If you are trying to restore the color of the wall, you don't need to separate it, just putty and fill the removed parts 24 hours before. But know that despite the differences between both of these renovations, wallpapers take less time than colors.
Installation
Wallpaper installation is usually done by professional installers with minimal mess. While color requires more time and leaves more dirt. With these interpretations, the color of the walls still needs a long time to dry.
Lasting
One of the most important advantages of choosing wallpaper over paint is its long-term durability. A standard wallpaper can last up to 15 years if installed properly, so wallpapers are a good choice for busy and high-traffic environments, where colors can be scratched and damaged by just a small bump. Of course, in wet spaces, it is better not to use wallpaper, because wallpapers are attached with glue and may come off easily.
