Abstract
A method of treating a fibrous panel having natural fissures in order to enhance and enlarge the natural fissures. The upper surface only of the fissured material is coated with a hardenable liquid abrasive resist which is subsequently hardened. This leaves the fissured areas unprotected by the resistant. The surface coated by the resist is abrasively treated to erode the fissures to enhance them while maintaining the planar surface treated with the resist unaffected by the abrasive treatment step.
