GranQuartz 314P Premium Impregnator is an ultra-high performance silicone (alkoxysilane) impregnator suitable and recommended for use on all natural stones, regardless of finish type. 314P is recommended for both interior and exterior applications, and provides maximum protection from water penetration and water-borne stains. Oil stain protection is also very good (the best we've seen for a silicone impregnator), outperforming some recent fluoropolymer products.
355E Color Enhancing Impregnator-Matte Finish is a color enhancing silicon impregnator intended for use on honed and textured stone only. 355E offers a high degree of protection that enhances the natural appearance of stone without gloss and protects it from water based stains and mineral deposits.
