Answer

80 removes heavily, 120 smooths early, 220 preps, 400 refines, 800–1000 wet sands fine, and 2000–3000 final-refines.

Why it happens
Each grit has a different role in removal, prep, refinement, or finishing.
Recommended grit
Use 80 for heavy removal, 120 for early smoothing, 220 for prep, 400 for fine prep, 800 and 1000 for fine wet sanding, and 2000 to 3000 for final refinement.
Wet or dry
Dry for removal and prep; wet for 800 grit and finer finishing stages.
Success check
The selected grit changes the surface without creating unnecessary deep scratches.

What to do

  1. Use 80 for heavy removal.
  2. Use 120 for early smoothing.
  3. Use 220 for general prep.
  4. Use 400, 800, 1000, 2000, and 3000 as the surface moves into fine finishing.
Avoid: Do not choose 3000 grit for heavy removal.
