Abstract

Abstract A sodium chloride filler for resin-based simulated stone products is disclosed, as well as a simulated stone product including the sodium chloride filler, and a method of preparing same. The product includes a resin base, a catalyst capable of polymerizing the resin and particulate sodium chloride. Pigments and other fillers may be included to yield special aesthetic effects. The method of the invention comprises the steps of mixing a quantity of the resin with catalyst and particulate sodium chloride, and perhaps pigment and other fillers. Two sodium chloride filler particle size ranges are preferred. Finally, the mixture is transferred to a mold, the mold having been coated with a gel coat, and/or a coat of resin with an alternative filler, in preparation for receiving the mixture. A kit including the foregoing ingredients and instructions for combining same is also within the scope of the invention.
