It actually turned into the perfect opportunity
to try BB Frösch Chalk Paint Powder. The powder is mixed with water first and then any flat latex paint to create a smooth, durable chalk paint that can be painted directly over any surface regardless of whether it is bare wood, metal, or previously painted. Primer is not needed! For a soft durable finish, you can add a coat of BB Frösch Clear Wax.
