Dry.
Success check
The wood feels even and the scratch pattern is consistent before finishing.
What to do
- Start only as coarse as the wood condition requires.
- Use 80 or 120 for rough areas.
- Move to 150 or 180 for smoothing.
- Finish with 220 when the surface is even.
Avoid: Do not start too fine on rough wood.
