SILRES BS 6538

SILRES BS 6538 is a PFAS-free siloxane-polymer treatment designed for mineral substrates such as stone, concrete and fiber cement. It provides both water and oil repellency, unlike traditional hydrophobic impregnations that only protect against water. The product preserves the substrate’s breathability while reducing the penetration of dirt and stains, making surfaces easier to clean and maintain. It is particularly suitable for natural stones such as granite, marble and travertine, as well as ceramic tiles, floors, countertops, window sills and façades.
