To use these Weha Electro Flex Electroplated Diamond Polishing Pads, first attach them to your polishing machine using the Velcro backing. For polishing marble, limestone, or travertine, start with a lower - grit pad and gradually move to higher - grit ones for a smooth finish. When working on granite to get a honed look, use the pads to remove the existing polish. Always keep the surface wet during the polishing process to prevent overheating and to get better results. After use, clean the pads with water to remove any debris. Store them in a dry place to avoid damage. Don't use these pads on extremely hard or abrasive materials other than what they're designed for, as it may cause wear and tear on the pads.
