Step 1 Prep your Wall and Attach the Baseboards
Once you’ve chosen the wall for your project, you’ll need to prep it. Begin by patching or filling any holes or nicks in the wall, then let it dry and sand it smooth. Once it’s smooth and dry, you can paint it with a coat of primer to get it ready for the slats. Then, using 2-inch brad nails, attach the baseboard along the bottom of the wall.
