HEPA dust containment
Also called dust-free sanding
High-efficiency extraction maintained throughout the sanding and finishing process, not only at final cleanup.
Dust generated during sanding is respirable and travels through the whole building. Cleanup afterwards addresses what settled, not what was breathed.
Containment is required throughout the process. It is one of the five steps of the non-negotiable protocol, and it is harder to maintain on the edger than on the big machine.

- 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.
- Progressive gritsWorking through abrasives from coarse to fine in sequence, with the perimeter matching the field at every step.
