Acoustical panel coating and process of applying same

An acoustical panel comprising:

• a substrate having a backing surface and a facing surface that is substantially free of punch holes, wheel abrasions, embossing and erosion, and wherein the thickness of the substrate is about 0.75 inches or less;
• and,
• a coating composition applied to the facing surface, wherein the coated substrate has an NRC value of about 0.50 or greater and a texture value of about 20 ml/sq ft or greater.

A coated scrim comprising:

• a scrim;
• and,
• a coating composition applied to said scrim, wherein the coated scrim has an airflow resistance in the range from about 600 mks rayls to about 900 mks rayls and a texture value in a range from about 20 ml/sq ft to about 65 ml/sq ft.

A suspended ceiling system comprising:

• a grid;
• a plurality of acoustical panels suspended by said grid, wherein each of the plurality of acoustical panels has a texture value in a range from about 20 ml/sq ft to about 65 ml/sq ft;
• and, a coated scrim suspended in said grid, the coated scrim having a texture value in a range from about 20 ml/sq ft to about 65 ml/sq ft and an air flow resistance value in a range from about 600 mks rayls to about 900 mks rayls.
