180 grit sandpaper

Fine

Pre-stain hardwoods. Soft enough not to leave swirls.

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.

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 fine furniture, between coats, auto-body, and dust-free sanding.

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.
