I say stick to the classic black or green chalkboard paint since it can be bought at the paint store, but if you need that special color, here's the "How To"...
Start with flat-finish latex paint in any shade. For small areas, such as a door panel, mix 1 cup at a time.
1. Pour 1 cup of paint into a container. Add 2 tablespoons of unsanded tile grout. Mix with a paint stirrer, carefully breaking up clumps.
2. Apply paint with a roller or a sponge paintbrush to a primed or painted surface. Work in small sections, going over the same spot several times to ensure full, even coverage. Let dry.
3. Smooth area with 150-grit sandpaper, and wipe off dust.
4. To condition: Rub the side of a piece of chalk over entire surface. Wipe away residue with a barely damp sponge.
Martha Stewart knows how to do everything. I'll never know how she does it.
