Sandpaper Widely used Abrasive Material

High sandpaper grits, starting at approximately 800, are used for surface refinement—this comes after using coarser sandpapers during the sanding phase. High sandpaper grits polish surfaces by extracting finer scratches that sandpaper with a lower grit leaves behind. In painting, high sandpaper grits serve as preparatory tools to finalize the surface before applying the main coat of paint. In the production of plastic products, high sandpaper grits enhance the appearance of the item while also refining the surface to prevent dust from accumulating.
