Workshop: Sandpaper Grit Reference

Choosing the Right Grit 40-60: Heavy removal, flattening rough wood. 80-120: Removing planning marks, general prep. 180-220: Pre-stain / Pre-finish smoothing. 320-400: Sanding between coats of finish. 1000+: Polishing metals or plastics. Rule: Never skip more than one grit level (e.g., go 80 -> 150 -> 220).
