The homeowner painted a large piece of smooth MDF wood and our carpenters put it on the wall and installed the frame around it. The chalkboard is not magnetic, but if you want it to be magnetic, you can use the same method, but instead of painting over the MDF wood, just paint over a magnetic surface, such as galvanized sheet metal (any hardware store like home depot will carry it). Just remember to sand the surface of the metal a little bit to help it accept the paint better and then back it with particle board or mdf (or something similar).

What chalk paint color was used here?
