Using Alpha PVA MS Style is easy. First, make sure your grinder is suitable for this product. Then, choose the right grit disc according to your polishing needs. For rough surfaces, start with an extra - coarse grit and gradually move to finer grits for a smooth finish. When using it for paint removal, just attach the disc to your grinder and start working on the painted area. It won't clog, so you can work continuously. When working on marble edges, corners, or other surfaces, keep the grinder moving evenly to avoid uneven polishing. Remember to always wear appropriate safety gear like goggles and gloves. As for maintenance, after each use, clean the disc to remove any debris. Store it in a dry place to ensure its long - term performance. If you notice the disc isn't working as effectively, it might be time to replace it.
