ABSTRACT:
In a method of making decorative panels, a liquid masking material is applied to a surface of a panel, and is cured to form a substantially solid masking layer on the surface. A pattern comprising at least one unmasked area and at least one masked area is formed in the masking layer either simultaneously with the application of the liquid masking material or subsequent to the curing step. The surface of the panel is then treated to render the unmasked areas of the surface of the panel visually distinguishable from the masked areas. In one embodiment of the invention the masking layer is elastomeric and the surface of the panel is treated by sandblasting, after which the masking layer is removed. The entire process may then be repeated to provide a dual density effect. In another embodiment of the invention an asphaltum masking layer is applied to a mirror forming layer on a panel, after which the portions of the mirror forming layer corresponding to the unmasked areas are chemically removed.
