Abstract:
1. A method for making a cast thermosetting polymer masonry wall panel reproduction that replicates on at least a part of its exterior surface, the surface and surface texture of an array of articles each of which is one of a natural stone article or a brick article while simultaneously imparting color to the exterior surface of the replicated articles in the cast masonry wall panel reproduction, said method comprising: using a mold having a cavity that replicates the surface of each one stone or brick article to be replicated in the array of articles in the masonry wall panel production; introducing castable thermosetting polymer material into the cavity of the mold; adding a powdered iron oxide compound to the cavity in the mold prior to introducing the thermosetting polymer material into said mold; locating the powdered iron oxide compound on a surface of the cavity to be retained by the introduced thermosetting polymer material over the exterior surface of each replicated article in the cast masonry wall panel reproduction; curing the thermosetting polymer material sufficiently in the mold to retain the powdered iron oxide compound over the exterior surface of each replicated article in the cast masonry wall panel reproduction; and imparting color and surface texture to the exterior surface of each replicated article from the powdered iron oxide compound retained over the exterior surface of each replicated article in the cast masonry wall panel reproduction.
