The amount of abrasive particles on an inch-square of sandpaper is used to gauge grit. The grit gets coarser with a lower number. For instance, sandpaper with a 40-grit has 40 abrasives per square inch, whereas sandpaper with a 600-grit has 600 abrasives per square inch. When Used in Sandpaper, How Do Grits Function? Whether you’re working with metal or plastic, always begin with a fine grit (150–220) and work your way up to a very fine grit (240 to 600).

They are good for smoothing out surfaces that have already been sanded with medium-grit sandpaper, removing small defects, and preparing surfaces for finishing.

The degree of abrasiveness of sandpaper is determined by the different grit sizes. The number of abrasive particles per square inch of sandpaper is referred to as grit. The grit is finer, and the surface is smoother, the higher the number. From very coarse (like 24 or 36 grit) to very small grit sizes are possible (such as 1000 or 1200 grit). Sanding a brand-new piece of wood should begin with a medium grit (80 to 120), progress to a fine grit (150 to 220), and then end with a very fine grit (320 or higher) (240 to 600).Make sure the surface is clear of dust and debris before you begin sanding. A dirty surface might clog your sandpaper and reduce the effectiveness of the sanding operation. To remove any dust or debris, use a clean cloth or a vacuum. Choose the appropriate grit for the job.

For instance, coarser grit sanding paper (like 24 or 36 grit) is appropriate for removing paint or significant amounts of rust from metal surfaces, but finer grit sanding paper (like 400 or 600 grit) is perfect for prepping surfaces for painting or finishing. How is grit assessed? The abrasive grains used in sandpaper, nowadays—contrary to common belief—are not actually sand. Natural abrasive materials, like garnet, and synthetic abrasives like aluminum oxide have mostly replaced sand, and they provide a superior performance offering a variety of sandpaper grit options.
