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 combination of primer + a high-performance cement mortar. Consult your setting materials manufacturer for specific recommendations. Regarding the installation of fiberglass mesh backed stones, consult with your fabricator/installer for recommended installation method. Options include but are not limited to complete removal of fiberglass mesh backing (where applicable) or installing with epoxy setting material. 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 like MORE™ AntiEtch™ can prevent acid etching. Resin fill is to be expected and not considered a flaw in this material. Minor vein washout is possible in wet installations. Seal all natural stone prior to grouting.
