Product must be installed in accordance with current TCNA handbook stone methods. The NSI recommends installing resin-backed stone with epoxy-based setting materials or a combination of primer and a high-performance cement mortar. Consult your setting materials manufacturer for specific recommendations. Plan your layout accordingly. Please be aware that veins in rosa perlino may open if used in showers and other wet areas. This material is sensitive to acids, including those commonly found in kitchens. Acid etching occurs in many stones but may be less visible on lighter colors and on surfaces with a honed finish. A professionally applied surface treatment, such asMORE™ AntiEtch™, can help prevent acid etching. Resin fill is to be expected and is not considered a flaw in this material. Minor vein washout is possible in wet installations. Seal all natural stone prior to grouting.
