Disclosed is a stain resistant acoustical panel. The panel may incorporate within its structure a relatively small quantity of latex which forms an ultra thin coating within the panel such that water may pass through the inner structure of the panel. Furthermore, the panel may have a coating or primer applied to the facing side of the panel to prevent water stains. The coating contains a chelating agent which provides stain resistance to the coated face of the panel. Additionally, the panel may incorporate both latex within its structure and a primer coating comprising a chelating agent.
