Abstract
Abstract A decorative building element comprised of at least one support layer of a foamed, cellular plastic material and a colored layer of an elastomeric organosilic material which adheres to the cellular material. The method comprises forming a paste of a self-vulcanizable material, mixing a color additive into the paste to disperse color into the paste, spreading the paste into a thin layer on a cellular foam plastic material to which the paste can adhere and vulcanizing the paste to form a decorative building element.
