What 180 grit is for

180-grit is the lower end of pre-finish grits. It removes 120-grit scratches cleanly and leaves a surface ready to receive stain or sealer on hardwood. For softwoods, 180 is often the highest grit needed before finish.

Projects at 180 grit

  • · Final sanding on pine furniture before stain
  • · Pre-finish prep on plywood projects
  • · Hardwood between-coat sanding for varnish
  • · Sanding cured wood filler smooth
  • · Smoothing turned spindles before finishing

Abrasive materials

  • · aluminum oxide
  • · garnet
  • · silicon carbide
  • · ceramic

Common mistake

On open-grain hardwoods (oak, ash, walnut), 180 may still feel rough: push to 220 if the stain finish needs to read smooth.

Use this grit when

The surface still needs this stage.

  • · Pre-stain hardwoods. Soft enough not to leave swirls.
  • · This is the working middle of most sanding progressions: enough bite to matter, refined enough not to leave the job stranded.
  • · On this site, 180 grit shows up most around between coats, Festool sanders, fine furniture, and knife making.

Skip this grit when

The job is earlier or later than this.

  • · Skip this grit if you still need heavy stock removal or if the surface is already ready for polish-level refinement.
  • · Skip the urge to jump straight here from a very coarse grit; the scratch pattern underneath will usually survive the shortcut.
