How much does floor sanding cost per square metre in Australia?

Most straightforward sand-and-polish jobs land in the range of roughly $30-$50 per square metre including finish. Badly cupped, painted, or parquetry floors, staircases, and premium two-pack finishes push it higher.

Is it cheaper to sand a floor yourself?

Materials for a DIY job (abrasives, primer, two coats of finish) typically run $8-$15 per square metre plus machine hire. The saving is real but so is the risk: drum marks from a hire sander are permanent until the next full sand.

Why do floor sanding quotes vary so much?

The floor's condition drives the price: previous coatings that must come off, cupping that needs extra passes, gap filling, staircases, furniture moving, and the finish spec. A quote that seems cheap usually assumes a clean, flat, empty floor.

How Much Does Floor Sanding Cost in Australia?

Prices vary with the floor, not the postcode marketing. Here is how the number is actually built.

TL;DR Straightforward sand and polish: roughly $30-$50 per m² including finish, in most Australian metro areas. Condition is everything -- old coatings, cupping, parquetry and stairs cost extra. DIY materials run $8-$15 per m² plus machine hire, and the trade-off is skill, not money.

What a professional job includes

A proper sand and polish is three trades' worth of work in one: machine sanding through a full grit sequence, edge and corner work, then a coating system applied in dust-controlled conditions. A typical quote covers:

Sanding -- belt sander through 3-4 grits, edger around the perimeter, buffer to blend the two. Here is the full process.
Coating -- primer plus two topcoats. The finish spec moves the price: a 1K water-based like Bona Mega costs less per litre than a commercial 2K like Bona Traffic HD.
Consumables -- abrasive belts and discs are a real cost; a hard, dirty floor eats them.

What pushes the price up

Old coatings. Thick solvent poly, paint, or bitumen off the boards means slow, coarse-grit work.
Cupped or uneven boards -- extra diagonal passes to flatten. Why floors cup.
Gap filling between boards -- labour-intensive if you want it done properly.
Stairs. Nearly all hand and edger work; often priced per tread.
Parquetry and herringbone -- grain runs in two directions, so the sanding sequence is more careful and slower.
Species. Ironbark and spotted gum blunt abrasives far faster than pine. Species guides here.

The DIY numbers

For a 40 m² living area, the materials from us come to roughly:

Abrasives -- belts and discs through the sequence: use the grit picker for the exact list.
Primer -- one coat at 8 m²/L: 5 litres. Classic UX for most species.
Topcoat -- two coats at 8-10 m²/L: 10 litres. The coverage calculator gives exact litres and pack sizes.

Machine hire (drum or orbital sander plus edger) is on top -- typically a weekend's hire from an equipment yard. Read DIY vs professional honestly before committing: the money you save is paid for in skill you must supply.

The cost nobody quotes: doing it twice

A botched sand -- drum stripes, edger swirls, a finish full of dust -- cannot be patched. It gets fixed by sanding the whole floor again, which means the cheap option cost more than the dear one. If your floor is your home's main feature, weigh that risk honestly. And a floor maintained properly needs this done once a decade at most: a screen and recoat at a fraction of the cost keeps a sound floor going indefinitely -- see the care guide.
