Sandpaper is produced in a range of grit sizes and is used to remove material from surfaces, whether to make them smoother (for example, in painting and wood finishing), to remove a layer of material (such as old paint), or sometimes to make the surface rougher (for example, as a preparation for gluing). Choosing the right sandpaper for your project starts with understanding grit numbers. Each number represents the sandpaper's coarseness, with lower numbers being coarser and higher numbers being finer. Coarser sandpaper sands material more aggressively than finer sandpaper.
