Answer
For light water rings, start with 220. Use 180 only when stronger leveling is needed.
Why it happens
Some marks are in the finish, while deeper stains may be in the wood. Sanding should start gently.
Recommended grit
Start with 220 for light surface marks. Use 180 only if the finish or stain needs stronger leveling.
Wet or dry
Dry.
Success check
The ring is reduced and the repaired area blends with the surrounding surface.
What to do
- Clean the surface first.
- Test 220 grit on the affected area.
- Use 180 only if 220 does not level the mark.
- Blend the area and refinish as needed.
Avoid: Do not sand through veneer or thin finish layers.
