# Hardwood floor sanding and refinishing in Toronto — the machine sequence

**What is the correct machine sequence for refinishing a hardwood floor?**

Four machines, each doing something the others cannot, in an order where every skipped step is a future liability that is invisible on handover day.

## Specification

| Item | Specification |
| --- | --- |
| Machine 1 | Belt floor sander — progressive grits, field only |
| Machine 2 | Floor edger — matching grits, every perimeter and detail |
| Machine 3 | Planetary / multi-disc — refining, blending field into edges |
| Machine 4 | Buffer / screening — final uniform surface and intercoat |
| Dust containment | HEPA throughout the process |

## Build sequence

1. Moisture testing and acclimation — minimum 72 hours in the actual conditioned space.
2. Belt sander, progressive grits, field only.
3. Edger, matching grits, on every perimeter and detail.
4. Planetary / multi-disc, refining and blending field into edges.
5. Buffer / screening for a final uniform surface.
6. Vacuum, tack, apply the finish system.
7. Intercoat screening with the buffer between coats.
8. Final coat.

## What goes wrong here

- A big machine cannot reach a perimeter. Skipping or under-gritting the edger leaves a visible halo around every room that only appears once the finish goes on.
- Without the blending pass, the boundary between what the belt sander reached and what the edger reached stays visible for the life of the floor.
- Intercoat screening is invisible on handover day and produces an uneven surface and weaker adhesion when skipped.
- Dry to walk on and fully cured are different dates. Furniture returned to an uncured finish marks it permanently.

## Related questions

### Can I stay in the house while my hardwood floors are refinished?

Most refinishing clients sleep at home every night of the job. Containment is HEPA-sealed extraction at the machine plus containment at the room. We publish no room-capture percentage because we have not measured one on a job. The water-based finishes are low-odour and walk-on ready in 2–4 hours.

### How long does hardwood floor refinishing take?

Refinishing is typically 3–5 days for a standard floor; a new installation on 1,000–1,500 sq ft runs 5 to 7 working days including moisture testing, acclimation, installation, then sanding, staining and finishing. The written estimate includes a committed schedule rather than a range.

### Should I refinish or replace my hardwood floor?

Refinish while there is wear layer left to remove and the boards are sound. Replace when the wear layer is spent, when boards are cupped or crowned beyond what a flat sand can correct without going through, or when the substrate underneath is the actual problem. The measurement that settles it is how much material remains above the tongue, and it is taken on site rather than guessed from a photograph.

## Recommendation

All four machines, in sequence, with intercoat screening. Equipment is not the difference between companies — the sequence and the discipline to complete it are.
