Floor sanding and polishing cost in Australia is quoted per square metre, and it is one of the few renovation lines where the finished result can be worth several times what it costs. Lifting a tired carpet off sound hardwood and having it sanded back and coated transforms a room for a fraction of what new flooring costs. The catch is that the rate assumes something about what is under the carpet, and the assumption is not always right.
This guide sets out the 2026 picture: the $/m² bands by coating system, the real decision between a recoat, a full sand and polish, and replacement, what actually moves a quote, and how long you are locked out of the room afterwards.
Restoring a floor is usually costed against replacing it, which is why it is worth reading alongside the cost to tile a floor in Australia. Both are priced by area, on the same logic as renovation cost per square metre.
A sand and polish is not a finish you buy.
It is timber you spend, and you only have so much of it.
How much does floor sanding and polishing cost in Australia
A full sand and polish in Australia is typically quoted between $30 and $60 per square metre for a standard polyurethane finish, with premium coatings and colour work pushing well above that. The coating system is the single clearest driver of the headline rate, and the scope of what is included underneath it is the reason two quotes at the same rate are not the same job.
| Scope | What it covers | Indicative rate (per m²) |
|---|---|---|
| Screen and recoat | Existing coating abraded, one or two fresh coats, no sand to bare timber | $25–40 |
| Full sand, solvent polyurethane | Sand to bare timber through the grit sequence, then three coats | $30–45 |
| Full sand, water-based polyurethane | Same preparation, low-odour fast-drying system, usually three coats | $35–50 |
| Hardwax oil, stain or lime wash | Colour work, penetrating finishes, extra application and buffing steps | $55–110 |
These are indicative 2026 market ranges, usually quoted GST-inclusive. Stairs are priced separately, commonly per tread rather than per square metre, because each one is edge work by hand. A colour change or stain typically adds $8 to $15 per square metre. Small rooms carry a higher rate per metre than a large open-plan area, because machine transport, dust extraction and set-up do not scale with floor size.
What is under the carpet, and can it actually be sanded
This is the question that decides whether the quote you received is valid, and it is answered by lifting a corner of carpet in a wardrobe before anyone quotes. Three things commonly sit under Australian carpet, and only one of them sands.
Solid tongue-and-groove hardwood is the prize. In older Australian housing it is often a full-thickness board with real depth above the tongue, and it can be sanded and coated several times across the life of the house. Structural particleboard sheet flooring is what sits under carpet in a great deal of housing built from the 1970s onward. It is a subfloor, not a finished floor, and it cannot be sanded and polished — the covering is the finish. Engineered boards sit in between and depend entirely on the wear layer.
That wear layer is a hard limit rather than a preference. The Australasian Timber Flooring Association distinguishes a veneer, often up to about 2 mm thick, from a thicker lamella of roughly 2.5 to 6 mm. A thin veneer generally allows one careful professional sand at most; below that, sanding cuts through the timber face into the plywood core and the floor is finished for good. Some engineered floors are also factory pre-finished and were never intended to be site sanded. Any contractor quoting an engineered floor without measuring the wear layer is quoting a guess.
In a house built before 1990, the vinyl or thermoplastic tiles and the black adhesive under the carpet or lino may contain asbestos — SafeWork NSW lists floor tiles among asbestos-containing products, and sanders, grinders and similar power tools must not be used on them.
Old floor coatings in a pre-1970 home can also carry lead. Neither is a reason to abandon the floor. Both are a reason to identify the covering before a machine touches it, and to price removal as its own line rather than as part of the sanding rate.

Should you recoat, sand and polish, or replace
These are three different jobs at three different prices, and most homeowners ask for the middle one by default. The test is what has failed: the coating, or the timber.
If the coating is dull, lightly scratched and worn in traffic lanes but the timber underneath is unmarked, a screen and recoat is the correct answer. The existing finish is abraded to give the new coat a key, and one or two fresh coats go on. It costs less, takes less time, and — decisively — spends no timber. A floor kept on a recoat cycle outlives a floor that gets fully sanded every time it looks tired.
If the damage is in the timber — deep scratches, water staining, pet marks, a colour change, gaps and cupping, or a coating that has failed in patches — a full sand and polish is what the floor needs, and it is where the money and the mess go. Replacement becomes the rational answer when the boards are structurally unsound, when a previous sand has already taken the board down near the fixings, or when the floor is a thin engineered veneer that has nothing left to give. At that point, restoring a floor and installing a new one converge in price, and the comparison sits inside the cost to renovate a house in Australia.
What actually drives the price of a sand and polish
The machine time is the smallest part. What separates a floor that reads as flat and even from one that shows every shortcut is the preparation and the discipline of the grit sequence, which is the part a cheap quote compresses. A properly scoped job runs through this sequence:
- Lift and strip. Carpet, underlay, smooth edge, staples and tacks all come out, and every staple left behind will tear an abrasive belt and mark the board.
- Assess and repair. The floor is checked for loose or cupped boards, protruding nails are punched below the surface, and damaged boards are replaced before any sanding begins.
- Coarse cut. The first pass takes off the old coating and levels the floor, and it is the pass that decides how much timber the job spends.
- Grit sequence. Successive finer abrasives remove the scratch pattern left by the pass before, and skipping a grit leaves marks that the coating magnifies rather than hides.
- Edges, corners and gap filling. Perimeters are worked with an edger and finished by hand, and gaps are filled where the floor calls for it, which is slow work and priced accordingly.
- Coating. Three coats are the norm for polyurethane, with a light buff between coats, applied in a clean and controlled room because anything airborne lands in the finish.
The Australian benchmark for that work is AS 4786.2, Timber flooring — sanding and finishing, with current trade practice set out in the ATFA industry standards. Both are worth naming in a written quote, because they give an agreed reference point if the finished floor is disputed. Dust extraction is the other line to check: a machine-mounted extraction system materially reduces airborne dust, but no system eliminates it, and a quote promising a completely dust-free result is overselling.
Which coating should you choose, and when can you walk on it
Three systems cover almost every Australian domestic floor. Solvent-based polyurethane builds a hard, high-build film, is the most economical per litre, and is the slowest to dry and cure while carrying strong odour. Water-based polyurethane dries far faster, has much lower odour, and holds the timber closer to its natural colour, at a higher price. Hardwax oil penetrates rather than forming a thick film, gives a matte natural look, and can be spot-repaired without recoating the whole floor, but needs periodic maintenance the film finishes do not.
Drying and curing are two different things, and confusing them is how a new floor gets marked in its first week. Drying is when the coat is hard enough to recoat or walk on carefully; curing is when the finish has reached full hardness and chemical resistance, which takes considerably longer. Follow the manufacturer's stated times for the specific product, and keep rugs and heavy furniture off well past the point the floor feels dry. Furniture dragged back too early leaves marks only another sand will remove.
Sequence matters as much as product. Sanding and coating happens after the messy trades and after painting, or with the painter returning to cut in the skirting once the floor is finished — the same coordination point covered in exterior painting cost in Australia, where paint and floors compete for the same window. In The 12-Phase System, floor finishing is a late fit-out item precisely because everything above it has to be done first.
What belongs in an itemised floor sanding quote
A quote that reads "sand and polish, 85 m², $3,800" is not a quote you can compare. The version you can compare names the substrate it assumes, the number of sanding passes, the coating product and the coat count, the treatment of edges and stairs, gap filling, dust extraction, rubbish removal and tip fees, and whether the price includes GST.
It should also name what happens when the floor turns out to be different from the assumption. Old floors are the most variation-prone surface in a renovation, because nobody can see the boards until the covering is off. Agree in writing how a variation is priced before the carpet is lifted — extra board replacement, an unexpected covering, or a wear layer too thin to sand are all foreseeable.
The rest is standard practice with licensed trades. Tie any progress claim to defined stages rather than dates. Inspect at practical completion under the light the room actually gets, at a low angle, looking for sanding marks, missed edge work, drum stops and dust in the finish, and raise them as a defects list before the final payment clears. The Housing Industry Association tracks renovation spend rather than trade rates, so the only number that matters is the one your own floor produces.

Frequently asked questions
How much does floor sanding and polishing cost per square metre in Australia?
A full sand and polish is typically quoted between $30 and $60 per square metre as an indicative 2026 range, usually GST-inclusive. Solvent-based polyurethane sits at roughly $30 to $45, water-based polyurethane at $35 to $50, and hardwax oil, stains and lime wash finishes run from about $55 to $110. A screen and recoat, which does not sand to bare timber, is cheaper at around $25 to $40.
Can you sand engineered timber flooring?
Only if the wear layer allows it. The Australasian Timber Flooring Association distinguishes a veneer, often up to about 2 mm, from a thicker lamella of roughly 2.5 to 6 mm. A thin veneer generally permits one careful professional sand at most, and below that, sanding cuts through into the plywood core and ruins the board. Some engineered floors are factory pre-finished and were never intended to be sanded on site, so the wear layer must be measured before anyone quotes.
What is the difference between a recoat and a full sand and polish?
A screen and recoat abrades the existing finish and applies fresh coats without sanding to bare timber, which suits a floor where the coating is worn but the timber is sound. A full sand and polish takes the floor back to bare timber through a sequence of grits and rebuilds the finish, which is what deep scratches, water staining and patchy failed coatings require. The recoat spends no timber, so a floor kept on a recoat cycle lasts longer.
How long before you can walk on a newly polished floor?
Drying and curing are different. A coat is dry when it is hard enough to recoat or take careful foot traffic; it is cured when it has reached full hardness and chemical resistance, which takes considerably longer. Water-based systems dry fastest and solvent-based polyurethane slowest. Follow the manufacturer's stated times for the product, and keep rugs and heavy furniture off well past the point the floor feels dry.
Is there asbestos under old carpet or lino in an Australian house?
There can be. In houses built before 1990, vinyl or thermoplastic floor tiles and the black adhesive beneath old coverings may contain asbestos, and SafeWork NSW lists floor tiles among asbestos-containing products. Sanders, grinders and similar power tools must not be used on asbestos-containing material. Old floor coatings in a pre-1970 home can also contain lead. Identify what the covering is before any machine is brought in, and price its removal as a separate line.
Is it cheaper to sand a floor or lay a new one?
Restoring sound solid hardwood is almost always cheaper than replacing it, which is why lifting carpet off good boards is one of the highest-return moves in a renovation. Replacement becomes rational when the boards are structurally unsound, when previous sanding has already taken them close to the fixings, or when a thin engineered veneer has nothing left to remove. At that point the two options converge in price and the decision moves to what you want the room to look like.
