Usage The grit size determines the smoothness of the finish. The lower the grit, the rougher the sandpaper; conversely, the higher the grit number, the smoother the sandpaper. Here’s a guide to grit grades and their common uses: 40-60: Coarse - Heavy sanding and stripping, roughing up the surface. 80-120: Medium - Smoothing of the surface, removing smaller imperfections and marks. 150-180: Fine - Final sanding pass before finishing the wood. 220-240: Very Fine - Sanding between coats of stain or sealer.
