Answer
After full cure, use 220 or 320 for leveling, then 400, 600, 1000, 2000, and 3000 for finer finish.
Why it happens
Epoxy finishing usually needs gradual refinement from leveling grits to fine wet sanding.
Recommended grit
Use 220 or 320 for leveling after cure, then 400, 600, 1000, 2000, and 3000 for finer finish.
Wet or dry
Dry for early leveling; wet for finer stages.
Success check
The epoxy sands to an even pattern without smearing.
What to do
- Confirm the epoxy is fully cured.
- Level with 220 or 320 if needed.
- Refine through 400 and 600.
- Wet sand with 1000 and finer for finishing.
Avoid: Do not sand soft or uncured epoxy.
