A coating composition and process of applying the coating to a substrate are provided herein. The coating composition includes filler particles, binder and a liquid carrier, such as water. The filler particles have an average particle size in the range from about 100 to about 600 microns and preferably in the range from about 200 to about 450 microns. The coating composition comprises from about 15% to about 50% by weight liquid carrier and from about 35% to about 90% by dry solids weight filler particles. The coating composition preserves the acoustic performance characteristics of the substrate to which it is applied, while imparting a textured appearance to the substrate, making the substrate virtually indistinguishable from surrounding panels.
