CLEANING Our stone panels should be cleaned periodically. A regular, seasonal cleaning program will help to maintain the aesthetics and life of the material. Rinse the sheets with lukewarm water. Remove dust and dirt from stone panels with a soft cloth or sponge and a solution of mild soap and/or liquid detergent in water. A 50:50 solution of isopropyl alcohol and water also works well. Rinse thoroughly with lukewarm water. Always use a soft, damp cloth to blot dry. Rubbing with a dry cloth can scratch the material and create a static charge. Never use scrapers or squeegees on stone panels. Also avoid scouring compounds, gasoline, benzene, acetone, carbon tetrachloride, certain deicing fluids, lacquer thinner or other strong solvents. DO • Use warm water, mild detergent and a soft cloth or chamois • Blot dry with a slightly damp soft cloth or chamois. • Keep cleaner one inch away from stand-offs or other mounting hardware. DO NOT • Use squeegees or scrapers as they may scratch the sheet. • Use scouring compounds or solvents such as: acetone, gasoline, benzene, carbon tetrachloride, or lacquer thinner to clean sheet. • Clean in hot sun or elevated temperatures. • Use a dry cloth or a cloth of synthetic fiber such as rayon or polyester as they may scratch the sheet. • Use cleaners around edges or holes where the cleaner can wick into the interlayer. REFINISHING One of the unique benefits of our stone panels (Honed Finish Only) is its ability to be refinished. If our stone panel requires refinishing to hide minor surface scratches, the panels may be renewed by light sanding. Begin by wet sanding with 320 grit followed by 600 grit paper to remove incidental blemishes/scratches. Be sure to keep sanders in motion at all times when refinishing surfaces or edges. Only use light pressure with power sanders in order to maintain evenness and avoid overheating of the sheet surface. Over sanding may result in pitting and will not be repairable. Our stone panels are able to be machined or routed into a variety of different forms. In addition to a straight edge, edges may accept beveling, rounding, etc. Additional finishing, such as sanding or polishing, can also be provided to some edges. STORAGE Stone should be stored at room temperature in a dry environment that is not exposed to direct sunlight or heat. Our stone panels should be stored horizontally (flat), as delivered, to prevent warpage. The protective masking must be removed within 30 days of receipt to prevent adhesive from sticking to the panel. Due to possibilities for expansion or contraction, allow material to come to room temperature prior to fabricating. USAGE LIMITATIONS Our stone panels should not be used in applications where the panel temperature will exceed 175°F (80°C). Instances where this temperature is exceeded may result in color fading or warping.
