After the base coat is cured, a non-opaque top coat is applied. The first step applies an opaque patina colored base coating to a primed or unprimed substrate. 4,416,940 which discloses a two step process to impart a simulated weathered-copper appearance to a substrate. While this allows the use of cheaper substrates, its effect is not aesthetically pleasing in that paint lacks the unique character and appearance of patinated copper.Ī variation of the approach described above is disclosed in U.S. Indeed, in many instances, the patination of existing copper architectural elements renders their repair aesthetically impractical.Īn obvious prior art attempt to mimic patination is the utilization of a uniform coating of paint of a desired tone (color). Thus, while the end result, and even intermediate stages, are considered desirable, the length of the patination process, and the variation in colors during that process, delay the visual effects and complicates any necessary repairs.
However, natural patination is very slow, taking as long as 20 years, or more. Patination of copper is a well known process and is desired in many architectural contexts for its unique, blue-green appearance. The present invention relates to copper architectural elements and, more particularly, to a simulated patina for such elements. After application, the colorant provides a simulated patina to the copper substrate surface while allowing the remaining (non-covered) portion of the substrate to patinate naturally. Non-uniformity may be accomplished by varying the volume of colorant sprayed during the application process or by varying the relative movement of the spray and substrate. The colorant is preferably a paint and may be applied by non-uniform spraying on the substrate surface. The interspersed spots of colorant may be produced by screen printing, by spattering, as by spraying, or by mechanical removal of colorant after application to the substrate surface, or a combination. The appearance of patination of the desired tone is created by interspersed spots of colorant with the remaining portion of the substrate being exposed for natural patination. A colorant having the desired initial patina color tone is employed to produce a non-continuous layer of colorant on the surface of a copper substrate.
