Then, gently wash with soap and water. Make sure to rinse well with clear water. This helps the paint stick better.
Dealing with Wallpaper and Wall Decals

Ensuring Surface Is Not Greasy
Also, check for greasy spots that can stop paint from sticking. Use your fingers to feel for slick spots. If it’s greasy, you’ll need to clean more thoroughly.
