Abstract
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.

Claim 1
Independent Claim
259 words
A method of making decorative panels comprising: forming a predetermined pattern on a screen such that a portion of the screen corresponding to the pattern permits the flow of liquid therethrough; applying liquid elastomeric masking material to a surface of a panel through the screen thereby applying the liquid elastomeric material to the surface of the panel in accordance with the pattern; curing the liquid elastomeric masking material on the surface of the panel and thereby forming a substantially solid masking layer on the surface of the panel in accordance with the predetermined pattern; impinging a high velocity stream of particulate material onto the surface of the panel having the masking layer thereon and thereby visually differentiating the unmasked portion of the surface of the panel from the masked portions thereof; subsequently removing the masking layer to provide a panel having visually differentiated areas corresponding to the previously masked and the previously unmasked portions of the surface of the panel; reapplying liquid elastomeric masking material to the surface of the panel through a second screen having a different pattern thereon thereby applying the liquid elastomeric material to the surface of the panel in accordance with the pattern on the second screen; curing the liquid elastomeric masking material on the surface of the panel; and impinging a high velocity stream of particulate material onto the surface of the panel having the masking layer thereon thereby visually differentiating the unmasked portion of the surface of the panel from the masked portions thereof to form a panel having a dual density pattern.
