Inspect your walls. The main thing to look for is to make sure they are clean and smooth. A simple washcloth can be used to remove any excess dirt. However, if there is leftover paint or any bumps in the wall that couldn't be removed, you may want to consult your local hardware store for the best way to smooth the wall.
Apply an adhesive to the wall. Make sure to find an adhesive that is strippable, dries clear and is easily cleaned with water.
Apply the mural to your wall. The specific instructions for this step will be included with the wall mural. After fully covering the wall, use the wallpaper trim tool to remove any excess wallpaper on any of the four sides.
