Abstract A process of forming a visible textural surface on a decorative acoustical panel having a fibrous body portion is disclosed herein. This process includes coating an exterior surface of the body with a film of hardening liquid, distributing individual granules of particulate material generally uniformly over a substantial portion of the exterior surface to provide a granular texture to the surface, and coating the granules with a film of hardening liquid, which film is insufficient to eliminate the granular texture but which adheres the granules to the exterior surface. Thereafter a part of the surface on which the liquid coated granules are located is indented. These indentations extend from the exterior surface and penetrate partway into the panel body to cause the displacement of part of the surface, thereby forming wall portions. These wall portions include some of the granules.

A process of forming a visible textural surface on a decorative acoustical panel having a fibrous body portion comprising: a. coating an exterior surface of the body with a film of hardening liquid; b. distributing individual granules of particulate material generally uniformly over a substantial portion of the coated exterior surface to provide a granular texture to said surface; c. coating the granules with a film of hardening liquid adhering the granules to the exterior surface, said film being insufficient to eliminate said granular texture; and d. thereafter indenting part of the surface on which the liquid coated granules are located, said indentations extending from the exterior surface penetrating part way into the panel body to cause displacement of said part of said surface thereby forming portions of walls, said walls including some of said coated granules, said coated granules on said exterior surface and on said walls of said indentations comprising a part of said visible textural surface of said panel.
