Progressive grits
Working through abrasives from coarse to fine in sequence, with the perimeter matching the field at every step.
The belt sander’s standard progression is 36 → 60 → 80/100. The edger follows the same sequence rather than running ahead of it.
Skipping a grit leaves scratches the next abrasive is too fine to remove, and those scratches become visible the moment finish goes on.

Terms this one depends on
- Belt floor sanderThe primary material-removal machine in a refinish: a continuous abrasive belt over a drum roughly 200 mm wide, handling around 80% of total removal.
- Floor edgerA compact high-speed rotating disc, typically 150–178 mm, that reaches walls, baseboards, closets, stairs and under cabinets — everywhere the belt sander physically cannot go.
- Planetary sanderA refining machine with three or more counter-rotating discs on a rotating head, producing a random multi-directional scratch pattern that blends field into edges.
- Intercoat screeningLight abrasion with the buffer between finish coats, to create the scratch pattern the next coat bonds to.
