How to Choose the Right Sandpaper
Yet we don't all use sandpaper the same. A trim carpenter may reach for a piece of 120-grit paper to quickly flatten a slightly offset miter joint, while a painter, spraying a catalyzed finish on cabinetry, may sand meticulously between coats with 400-grit or higher to make the finish as smooth as glass.
