What Do The Different Grits Mean In Sandpaper?
Sandpaper comes in different grit levels, which are indicated by a number. The higher the number, the finer the grit. For example, 60 grit sandpaper will be more coarse than 120 grit sandpaper.
In general, lower grits (40 to 100) are used for rough sanding, while higher grit numbers (120 to 220) are used to prep for finishing.
For most woodworking projects, we recommend using a progression of grits from 80 grit for rough sanding and ending at 220 grit for finishing prep. However, for certain projects such as when using epoxy, you may want to use even higher grits for an ultra-smooth finish.
