Sandpaper is an essential tool for woodworking projects and is also great for removing scratches and rust or preparing your project for a fresh coat of paint or stain. Different types of sandpaper are suited for different materials. Some sandpaper is the right choice for power sanding, while very fine-grit sandpaper is best for sanding by hand.
Sandpaper grit refers to how large the abrasive particles are; the lower the number of grit, the larger the particle and the more abrasive the sandpaper is. Higher number grit is finer, removes less material and makes smaller scratches in the surface you're sanding. Generally when sanding, you'll start with lower number grit and work your way up to finer, higher number grit to get a perfectly smooth surface.

For power sanders, you'll likely need sanding discs or belt-style sheets of sandpaper, depending on the style of sander. Be sure to use safety precautions and wear a dust mask when sanding.
