Maintenance Guidelines
Clean regularly with a pH-neutral stone cleaner. Avoid acidic and abrasive cleaning products. Seal periodically, especially in high-traffic or exterior installations. Remove spills promptly. Use protective pads beneath heavy furniture. Avoid dragging metal objects directly across the surface. Reseal every 2–4 years depending on usage conditions.
