To use these Stinger™ concrete polishing pads, first make sure the concrete floor is clean and dry. Attach the pad to your polishing machine according to the machine's instructions. Start polishing at a slow speed and gradually increase it for better results. As you work, keep the pad wet to prevent overheating and to get a smoother finish. When you're done, clean the pad with water and let it dry. Store the pads in a cool, dry place. Avoid using these pads on surfaces other than concrete, as it may damage the pads and not give the desired results.
