Answer
For live edge wood, level rough areas with 80 or 120, then finish with 150, 180, and 220.
Why it happens
Flat areas and natural edges need different handling so the edge is not destroyed while the surface is leveled.
Recommended grit
Use 80 or 120 for rough saw marks, then 150, 180, and 220 for finish prep.
Wet or dry
Dry.
Success check
The slab top is smooth while the natural edge still keeps its shape and texture.
What to do
- Start flat areas with 80 or 120 only where rough.
- Move through 150, 180, and 220.
- Hand sand the natural edge lightly.
- Clean dust before finishing.
Avoid: Do not flatten or erase the natural edge with heavy sanding.
