The disclosure provides a curable coating composition including 10-50 vol. % inorganic binder, based on the total volume of solids in the dry coating composition, wherein the inorganic binder is an alkali metal silicate or an alkaline earth metal silicate and 50-90 vol. % inorganic filler, based on the total volume of solids in the coating composition, wherein the binder and the filler are not the same and the coating is substantially free of an organic polymeric binder. Further provided are ceiling tiles having a backing side and an opposing facing side, and a cured coating layer supported by the backing side of the panel, the cured coating layer including the curable coating composition of the disclosure and methods of preparing same.
