Answer
For light pet scratches, use 180 or 220. Use 120 only for deeper scratches, then refine to 220.
Why it happens
Floor scratches often vary in depth. Light scratches need blending; deeper scratches may need refinishing beyond spot sanding.
Recommended grit
Use 180 or 220 for light blending. Use 120 only for deeper visible scratches, then refine to 180 and 220.
Wet or dry
Dry.
Success check
The scratch is blended and the repair area does not show a hard sanding edge.
What to do
- Clean the scratched area.
- Start with 180 or 220 for light scratches.
- Use 120 only if the scratch is still visible.
- Blend the area with 180 and 220 before finishing.
Avoid: Do not spot sand a deep low area into the floor.
