Answer
For light burn marks on wood, use 120 or 180, blend the area, then finish with 220.
Why it happens
Burn marks darken the surface fibers and may need controlled sanding until the damaged layer is removed.
Recommended grit
Use 120 or 180 for light burn marks, then 220 for final prep.
Wet or dry
Dry.
Success check
The dark mark is removed or reduced and the repair blends with the surrounding wood.
What to do
- Sand with the grain using 120 or 180.
- Check often so you do not create a low spot.
- Blend the area into the surrounding wood.
- Finish with 220 before stain or finish.
Avoid: Do not keep sanding deep burn damage in one small spot.
