How Floor Sanding Works

A step-by-step look at how Russell sands and finishes your timber floors, from first inspection to final handover.

Every job follows the same methodical process. Russell uses professional-grade Bona sanding equipment and finishing products on every floor. A typical 3-bedroom home takes 2-3 working days. Here is what to expect.

Before the job

Initial Assessment

Russell comes to your home for a free, in-person inspection. He will assess the floor condition, identify the timber species, check for damage, loose boards, moisture issues and previous coatings. You will get an honest assessment of what the floor needs and a clear quote on the spot. No obligation.

Day 1 - Morning

Preparation

The room is cleared of furniture (Russell can help with this). All protruding nails are punched below the surface to prevent damage to sanding belts. Any loose or damaged boards are secured or replaced. Adjacent areas, skirting boards and fixtures are masked and protected with plastic sheeting. Dust extraction is set up.

Duration
1-2 hours

Day 1

Coarse Sanding

The first sanding pass uses a coarse grit (40-60) on the belt sander to remove old coatings, stains and surface damage. This is the heaviest cut and levels the floor, addressing any unevenness between boards. The edge sander handles the perimeter and corners that the belt sander cannot reach. Dust extraction runs continuously throughout.

Equipment
Bona Belt Sander + Edger
Grit
40-60 grit
Purpose
Remove old finish, level floor

Day 1

Medium Sanding

The second pass uses a medium grit (80-100) to remove the scratches left by the coarse sanding. This refines the surface and brings the timber to a more uniform texture. The edge sander follows the same progression. Russell inspects the floor after this stage for any areas that need additional attention.

Grit
80-100 grit
Purpose
Refine surface, remove coarse marks

Day 1 - Day 2

Fine Sanding

The final sanding pass uses fine grit (120) to produce a smooth, even surface that is ready for coating. This stage determines the final quality of the finish, so Russell takes extra care. After fine sanding, the floor is thoroughly vacuumed and tacked to remove all dust particles.

Grit
120 grit
Purpose
Final smooth finish

Day 2

Gap Filling

Gaps between boards are filled with a mixture of sanding dust (from your own floor) and resin binder. This creates a colour-matched filler that blends with the surrounding timber. Russell fills all visible gaps, nail holes and minor surface imperfections. Once dry, the filled areas are sanded smooth and flush with the board surface.

Material
Timber dust + resin (colour matched)
Drying time
1-2 hours
Gap filling works best on gaps up to approximately 3mm. Larger gaps in older floors may be addressed with timber strips or flexible fillers. Russell will discuss options during the assessment.

Day 2 - Day 3

Coating Application

Three coats of Bona polyurethane are applied with a professional roller and applicator. The first coat seals the timber. After it dries (3-4 hours), a light buff with a fine screen removes any raised grain. The second and third coats build the protective film. Russell offers satin, matt and gloss finishes, and can apply Bona stains for custom colour effects.

Curing & Handover

After the final coat, the floor needs time to cure. You can walk carefully on the floor after 24 hours (socks, no shoes). Furniture can be placed back after 48 hours (with felt pads). Full cure takes 7-14 days. Russell walks you through the care instructions and recommends maintenance products. See the full floor care guide for ongoing maintenance advice.
