Sanding drywall Using very fine grit sandpaper requires minimal pressure and careful, even strokes to obtain a uniformly clean surface. Avoiding over-sanding is also crucial, as a too-smooth surface will not accept the final paint or varnish coat. Super Fine Grits (320-600)

Before applying the last layer of paint or varnish, superfine grits are perfect for final sanding.

Knowing about sandpaper grits might help you choose one for your project.

Sandpaper grit is what makes it abrasive. Manufacturers grade sandpaper based on the size of the grit, and the grade you need depends on the job.

Various grits of sandpaper are needed for various applications.

How is grit assessed? Woodworking, metalworking, automotive, glassworking, paint and finishing, drywall sanding, and sanding concrete and masonry are just a few of the many industries that rely on sandpaper grits. Woodworking Large particles fit through larger holes. Because they’re larger, a standard filtering screen requires fewer of them. Consequently, coarser grits are known by smaller numbers than finer grits, much like larger-diameter wires have smaller gauge numbers in the American Wire Gauge system. Silicon carbide sandpaper: This is another synthetic option that can be used for wet sanding surfaces. It can also self-sharpen when used against especially rough edges.

These sandpapers have widespread application in the woodworking industry, especially for use in between layers of varnish or paint to smooth and polish the surface. Also, you can use them to sand down metal surfaces to get rid of corrosion, oxidation, or minor scratches. Aluminum oxide sandpaper: Synthetic in nature, this type is great for manual and orbital sander use and offers an extended lifespan as its edges wrinkle just enough to expose new abrasive material.Extra-fine (320- and 360-grit): The first of the micro-abrasives, this is primarily for sanding finishes before polishing.

Metalworkers use sandpaper of varying grits to smooth out defects like rust and paint. It’s crucial to know the different sandpaper grits and the numbers that correspond to them. The grit of sandpaper indicates the average number of abrasive grains per square inch. The finer the abrasive particles and the higher the grit number, the smoother the final product will be. There are various varieties of sandpaper grits available, each with its own distinct abrasive qualities. These different sandpaper grits consist of: Coarse Grits (40-60) Fine (100- and 120-grit): The best utility sandpaper. Fine grades smooth scratches left by coarser grades and rough up painted surfaces before accepting new paint. They’re also good for sanding drywall. When you just need some for hand-sanding, or to use with an orbital sander, this is the grade you’ll most likely use.
