Answer
You can skip only when the next grit removes the previous scratches. Do not jump from coarse to ultra-fine.
Why it happens
Skipping grits can leave scratches that the next fine grit cannot remove efficiently.
Recommended grit
Use gradual steps such as 80, 120, 180, 220, 320, 400, 600, and finer where needed.
Wet or dry
Dry or wet depending on surface and stage.
Success check
Each grit removes the previous grit pattern before moving finer.
What to do
- Check the scratches from the current grit.
- Move only to a grit that can remove them.
- Add an intermediate grit when scratches remain.
- Clean between grits.
Avoid: Do not jump from coarse grits directly to ultra-fine grits.
