Of course you can, but it also depends on your experience and skill. However, if you are wallpapering for the first time, and if the purchase price of the wallpaper was higher, we recommend using the services of professionals. The application of the wallpaper will take the professionals much less time than it will take you. You also don't risk messing something up and losing money unnecessarily. However, when you want to apply the wallpaper yourself, read the instructions on the wallpaper carefully and check the symbols on it. Each wallpaper material requires a different process and adhesive. It's important to use a primer before wallpapering so that your wallpaper adheres and sticks well.
