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
The assembled 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
Sequence
The sequence, start to finish
- Moisture testing and acclimation — minimum 72 hours in the actual conditioned space.
- Belt sander, progressive grits, field only.
- Edger, matching grits, on every perimeter and detail.
- Planetary / multi-disc, refining and blending field into edges.
- Buffer / screening for a final uniform surface.
- Vacuum, tack, apply the finish system.
- Intercoat screening with the buffer between coats.
- Final coat.
Failure modes
Where this goes wrong
- 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.
Answer
What we recommend
All four machines, in sequence, with intercoat screening. Equipment is not the difference between companies — the sequence and the discipline to complete it are.

Related questions this guide answers
- 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.

Prices for all three bands are published before you call — hardwood flooring in Toronto for a new floor, refinishing for an existing one, stairs for the part usually left out of the quote. If the floor is already cupping, gapping or lifting, this is a diagnosis rather than a decision: what your floor is telling you.
Proof, with the numbers
Where these decisions were made on real jobs
Each publishes the readings and the reasoning, not only the result — which is what makes them worth reading next to a guide rather than instead of one.
Distillery District, over concrete
Over a concrete slab: the moisture test decided the assembly before a species was chosen.
Rosedale estate, stairs over radiant heat
Radiant heat under a main floor and a staircase, with the thermal range designed for.
Forest Hill, wide-plank walnut
Wide-plank walnut, and keeping the colour uniform across boards that age photochemically.
Every case study publishes what was measured, not only what was achieved — all of them are here, and each one names the substrate, the species, the readings and the protocol it followed.
