You can turn any surface into a chalkboard/magnet. It's pretty cool. I've seen refrigerators, kitchen walls, kids rooms, and entry ways all accented with chalkboard/magnetic paint. You can use it to draw pictures, make grocery lists, write out recipes, provide background for your artwork, and educate your kids.
Step 1 - Prepare Surfaces
Once you have selected the wall(s) to paint, clean the surface and repair all imperfections. Lightly sand the entire area to be painted with fine (#220) grit garnet paper, then wipe off with clean rags.
Step 2 - Taping/Priming
Use masking tape to tape off the area around the surface you are planning to paint. Next you'll need to prime the surface. Priming is needed to ensure adhesion of topcoat and to block all stains. Prime the entire surface to be painted. Allow to dry.
Step 3 - Painting
Apply the chalkboard paint with either a roller, nylon brush, or foam brush. Two coats will give you the best finish. Allow a week for the paint to cure.
