Answer
For hardwood floor edges, match the main floor sequence: 60 or 80 for leveling, then 100, 120, and 150.
Why it happens
Edges often need grit progression that matches the main floor field.
Recommended grit
Use 60 or 80 for rough leveling, then 100, 120, and 150 for refinement.
Wet or dry
Dry.
Success check
The edge scratch pattern matches the surrounding floor.
What to do
- Match the edge grit to the main floor sanding stage.
- Use 60 or 80 only for rough leveling.
- Refine with 100 and 120.
- Finish with 150 before coating when appropriate.
Avoid: Do not leave coarse edge scratches next to smoother floor areas.
