A decorative coatings method, system, device, and composition, wherein the initial part may be the blending of several materials to create the face coat. The next step may be the application of this face coat into a mold. Then the backfilling of this mold with another blended material that is not usually associated with the face coat. The method ensures the adhesion of the backfill to the face coat. The specific mixtures allow the materials to bond and form a solid product when removed from the mold.
