First, paint your darker color your board and allow the paint to dry.  For this board, I only painted the edges but for my next, I covered the entire board with the undercoat. I strongly suggest painting the entire board. Next, paint over your first coat of paint with your primary paint color and allow it to dry. Add a second coat if needed and give it time to dry as well.
