Epoxy flooring cost per square metre in Australia 2026
Epoxy flooring cost in Australia sits between $40 and $180 per square metre in 2026, supply and install, inc. GST. Most residential garage jobs land in the $65–$95 per m² band for a standard flake system.
That's a wide spread, and the reason catches a lot of people out. You're not really paying for the epoxy — a 20-litre kit of two-pack from Bunnings doesn't cost much. You're paying for what happens to the concrete before the coating goes down, and that varies enormously between a five-year-old slab in a Brisbane new build and a cracked 1970s garage floor in Melbourne's inner west.
This guide breaks down the real per-m² rates by system type, what a double garage actually costs, and where quotes quietly blow out. If you want job-specific numbers from a local specialist, start with the flooring tools in Leadkit's calculator library and get a tradie to price your actual slab.

Key takeaways
- Epoxy flooring costs $40–$180 per m² in Australia in 2026, with most residential garage work at $65–$95 per m² for a flake system, supply and install, inc. GST.
- A standard double garage (about 36 m²) costs roughly $2,400–$3,400 for a ground, primed, flaked and clear-coated floor.
- Surface preparation is the single biggest cost driver — diamond grinding a slab typically accounts for 30–40% of the job, and skipping it is the most common reason epoxy peels.
- Small floors cost far more per m² than big ones. Across 53 quote calculators in Leadkit's library that carry a minimum job fee, the median minimum is $800 — so a 12 m² single-bay floor gets priced by the callout, not the square metre.
- Polished concrete generally costs more up front than epoxy ($65–$150 per m²) but lasts longer on a slab that's already in good nick.

How much does epoxy flooring cost per square metre?
Epoxy flooring costs $40 to $180 per square metre in Australia in 2026, depending on the coating system, the condition of the slab and how much preparation the floor needs. The table below shows typical installed rates and what a standard 36 m² double garage works out to.
| Epoxy system | Cost per m² (inc. GST) | Double garage (36 m²) | Best for |
|---|---|---|---|
| Basic roll-on solid colour (2 coats, light prep) | $40–$60 | $1,500–$2,200 | Tidy slabs, budget refresh |
| Standard flake system (grind, primer, flake, clear coat) | $65–$95 | $2,400–$3,400 | Most home garages |
| High-build 100% solids epoxy | $90–$130 | $3,200–$4,700 | Workshops, heavy vehicles |
| Metallic / designer epoxy | $120–$180 | $4,300–$6,500 | Showrooms, display garages |
| Polyaspartic topcoat upgrade | +$25–$45 | +$900–$1,600 | UV stability, faster return to service |
| Commercial / warehouse grade | $80–$200 | Quoted per site | Factories, food areas, car parks |
How we built these ranges (methodology): Leadkit doesn't publish a dedicated epoxy calculator, so these figures aren't a direct read-out of one tool. They're compiled from current Australian supply-and-install rates for comparable floor-preparation and surface-coating work, then sanity-checked against the real rate cards behind Leadkit's construction calculators. Those rate cards are worth a look on their own: across the 23 per-square-metre rate variables in the library, the median default rate is $40 per m², but the middle half of them spread from $28 to $125 per m². Trade rates quoted "per m²" are genuinely that variable, which is exactly why one epoxy quote can be double another and both be fair.
Leadkit is the platform those calculators run on, so treat this as our own data rather than neutral third-party research.
This is a price indication only. Your tradie will confirm the final price after assessing the job.
What does an epoxy garage floor cost?
An epoxy garage floor costs about $1,500–$3,400 for a standard double garage in Australia in 2026, with most homeowners spending around $2,400–$3,400 on a flake system. Single garages usually come in between $1,200 and $2,200.
Rough floor areas to measure against:
- Single garage — around 18–20 m²
- Double garage — around 36 m²
- Triple garage or garage plus workshop — 50–60 m²
- Carport or alfresco slab — 20–40 m²
The per-m² rate drops as the floor gets bigger. Grinding gear has to be carted in, plugged in and dust-extracted whether the floor is 12 m² or 120 m², so that fixed cost gets spread thinner on a larger job. On a small single bay you're often paying close to a day rate dressed up as a square-metre price.
That's the pattern behind the minimum-job-fee number above. A median minimum of $800 across 53 of Leadkit's quote calculators means most trades simply won't roll a truck for less — epoxy specialists included.
Getting three quotes on the same measured area is the only way to compare like for like. Measure your floor in metres, multiply length by width, and give every tradie that same number.
What drives the epoxy flooring price per m2 up or down?
Surface preparation is the biggest single variable in any epoxy quote, and it's usually 30–40% of the total. Everything else is secondary.
Diamond grinding. A proper prep means running a diamond grinder over the slab to remove laitance — the weak, powdery cement-rich skin left on the surface when concrete cures. Epoxy bonded to laitance will lift in sheets. Some cheap quotes substitute acid etching, which is faster and much less reliable on a power-floated garage slab.
Moisture in the slab. Concrete on ground constantly passes water vapour upwards, known as moisture vapour transmission. If the slab has no working vapour barrier under it, that moisture pushes the coating off from below as blistering. A moisture-tolerant primer adds roughly $10–$20 per m², and a tradie who tests for this before quoting is doing you a favour, not padding the price.
Crack and joint repair. Structural cracks, spalling and old control joints get cut out, filled with a flexible epoxy or polyurea and re-ground. Budget $150–$600 on a typical garage.
Existing coatings. Stripping a failed paint or old epoxy layer can add $15–$35 per m². Tiled or glued-down floors cost more again.
Dry film thickness. DFT is how thick the cured coating actually is, measured in microns. A 300-micron high-build system uses several times the product of a thin roll-on at 150 microns, and that shows in the price. It's the number to ask about when two quotes look suspiciously far apart.
Finish choices. Broadcast flake, anti-slip aggregate, cove skirting up the wall and colour-matched topcoats all add cost. Anti-slip matters if the floor gets wet — surfaces are classified under the Australian Standard AS 4586 for slip resistance, and any decent commercial installer will talk you through it.
Access and timing. Second-storey floors, tight side access, and jobs needing weekend or after-hours work all carry loadings, same as any trade.
Want a feel for how tradies build a per-m² rate? The concreting quote calculator shows an instant estimate for concrete work using real Australian rates — useful for the slab itself, though the epoxy coating is quoted separately by the flooring specialist.
Epoxy floor coating vs polished concrete
Epoxy floor coating is generally cheaper to install than polished concrete, but polished concrete lasts longer where the existing slab is sound. Epoxy sits on top of the concrete as a sacrificial layer; polishing grinds and densifies the slab itself, so there's nothing to peel.
| Epoxy coating | Polished concrete | |
|---|---|---|
| Typical cost per m² | $40–$180 | $65–$150 |
| What it is | A coating applied over the slab | The slab ground and densified |
| Realistic lifespan | 8–15 years residential | 20+ years |
| Failure mode | Peeling, blistering, UV yellowing | Surface dulling, needs re-polish |
| Slab condition needed | Forgiving — hides patches | Unforgiving — flaws show |
| Colour options | Any colour, flakes, metallics | Limited to the concrete and aggregate |
| Chemical resistance | Excellent | Moderate, needs sealing |
The practical rule: if your slab is patchy, stained or has been chopped up by plumbing work, epoxy hides all of it. If you've got a clean, well-poured slab and want a finish that never needs recoating, polishing is the better long-term buy. Our polished concrete floor cost guide runs through those numbers properly.
Worth knowing: neither option fixes a bad slab. If the concrete is dished, cracked through or has drainage problems, that gets sorted first — see the concrete slab cost guide for what a replacement pour runs to.
What the per square metre rate actually includes
A complete epoxy flooring quote should cover preparation, primer, the build coat, the decorative layer and the topcoat — not just the coating itself. Quotes that only list "epoxy floor coating, $X per m²" are where disputes start.
A properly scoped job includes:
- Site protection and dust extraction — grinding concrete releases crystalline silica dust, and Safe Work Australia sets the workplace exposure standards installers work to. Vacuum-shrouded grinders are the norm, not an extra.
- Diamond grinding of the full floor to an open, mechanically keyed profile.
- Crack, joint and divot repair, itemised separately if significant.
- Primer coat, moisture-tolerant if the slab needs it.
- Build coat of epoxy at a stated dry film thickness.
- Decorative layer — flake broadcast to rejection, or pigment, or metallic.
- Clear topcoat, either epoxy or polyaspartic. Polyaspartic costs more but holds colour under UV and lets you park sooner.
- Cure and return-to-service times in writing. Foot traffic is usually 24 hours; vehicle traffic is typically 5–7 days for epoxy topcoats.
Across the construction quote calculators running on Leadkit, the line homeowners consistently underestimate isn't the finish they picked — it's the preparation underneath it. When a tradie's rate card is built properly, prep is its own line item, and that transparency is usually a sign you're dealing with someone who's done this before.
Products you'll see named in quotes include Dulux Luxafloor, Sikafloor and Rust-Oleum systems. Any of them will do the job; the installer's prep matters more than the brand on the tin.

How to compare epoxy flooring quotes
Compare epoxy quotes on preparation method, dry film thickness and warranty — not on the headline per-m² rate. Three quotes at $55, $78 and $95 per m² are often three completely different jobs.
Ask every installer the same five questions:
- How are you preparing the slab? Diamond grinding is the answer you want. "Acid etch" or "clean and coat" on a garage floor is a warning sign.
- Have you moisture-tested the concrete? On any slab older than about 20 years, or anywhere with damp patches, this matters.
- What's the dry film thickness? A stated micron figure beats "three coats" every time.
- What does the warranty actually cover? Delamination and blistering are the failures worth insuring against. Ask how long, and get it written down.
- Is the price inc. GST, and is there a minimum job fee? On small floors the minimum often is the price.
Check licensing too. Applied floor coatings sit in a grey area between painting and specialist coating work, and the licensing threshold varies by state — NSW Fair Trading publishes the current thresholds for residential building work, with the VBA in Victoria and QBCC in Queensland doing the same. For general standards and contract guidance, Master Builders Australia and the Housing Industry Association are the bodies worth reading before you sign anything.
One last thing on timing: ABS construction input data has shown steady rises in materials and labour through recent years, so a quote from six months ago probably isn't valid today. Get fresh numbers.
Frequently asked questions
Q: How much does epoxy flooring cost per square metre in Australia?
A: Epoxy flooring costs $40 to $180 per square metre installed in Australia in 2026, inc. GST. Most home garages land at $65–$95 per m² for a flake system — grind, primer, flake broadcast and a clear topcoat. Basic roll-on solid colour coatings on a tidy slab start around $40 per m², while metallic and designer finishes run to $180 per m². Commercial and warehouse-grade systems are quoted per site because the prep, thickness and downtime requirements change everything. The rate always depends more on the concrete's condition than on the coating you choose, so nobody can give you a firm figure without seeing the floor.
Q: What does an epoxy garage floor cost for a double garage?
A: An epoxy garage floor costs about $2,400–$3,400 for a standard double garage of roughly 36 m² using a flake system. A budget roll-on finish on a slab in good condition can come in at $1,500–$2,200, and a high-build or metallic finish pushes past $4,300. Single garages of 18–20 m² typically run $1,200–$2,200. Remember that smaller floors carry a higher effective per-m² rate because setup and grinding costs are largely fixed. For a sense of how tradies build a per-m² coating rate, the painting quote calculator shows an instant estimate on real Australian surface-coating rates.
Q: Is epoxy flooring cheaper than polished concrete?
A: Yes, in most residential cases epoxy is cheaper to install. Epoxy runs $40–$180 per m² against $65–$150 per m² for polished concrete, and the gap widens on floors needing repair, because epoxy hides patching that polishing would expose. Polished concrete wins on lifespan — 20 years or more against 8–15 for a residential epoxy coating — and it never delaminates because there's no separate layer to lift. If your slab is sound and you want to do it once, polish it. If it's stained, patched or you want a specific colour, epoxy is the better value.
Q: How long does an epoxy floor last?
A: A properly prepared residential epoxy floor lasts 8–15 years, and commercial-grade systems in light traffic can go 20. Preparation decides almost all of it. A coating applied over unground concrete or a damp slab can fail within 12 months, which is why grinding and moisture testing are worth paying for. UV exposure is the other factor — standard epoxy yellows in direct sunlight, so outdoor and near-window areas want a polyaspartic topcoat. Hot tyre pickup, where warm tyres lift the coating, is almost always a prep failure rather than a product one.
Q: Can I do epoxy flooring myself?
A: You can, and a DIY kit for a double garage costs roughly $400–$900 from Bunnings or a coatings supplier. The catch is preparation. Hiring a diamond grinder with dust extraction runs $150–$300 a day, and doing it properly is hard physical work. Most DIY epoxy failures come down to inadequate grinding, coating a damp slab, or rolling on too thin. If the floor is in good condition and you're happy with a thinner finish, DIY is a genuine saving. If there's any moisture or cracking, the money you save gets spent twice.
Q: How long before I can park on a new epoxy floor?
A: Foot traffic is usually fine after 24 hours, but vehicles need 5–7 days on a standard epoxy topcoat. Driving on it early is the fastest way to ruin a new floor — the coating is still curing and hot tyres will mark or lift it. Polyaspartic topcoats cure much faster and can take vehicles in 24–48 hours, which is part of why they cost $25–$45 per m² more. Ask for the return-to-service times in writing before booking, especially if you can't park elsewhere for a week.
Q: Does epoxy flooring add value to a house?
A: It adds appeal more reliably than it adds valuation. A clean, sealed garage floor presents well at inspection and signals a maintained property, which matters in competitive markets like Sydney, Brisbane and Perth. It's rarely a line item a valuer prices separately, though. Treat it as a durability and presentation upgrade that happens to look good, rather than an investment. If you're renovating to sell, the money usually works harder on the kitchen or bathroom — our flooring cost guides cover how the different surfaces compare.
Final tips before you book an epoxy floor
Measure your floor properly before you ring anyone. Length times width in metres gives you the m², and that one number lets you sense-check every quote against the table above.
Book prep and coating with the same crew. Where grinding is subcontracted separately, nobody owns the bond, and that's exactly the argument you don't want if the floor lifts in year two.
Get it in writing: preparation method, dry film thickness, topcoat type, cure times, warranty terms, and whether the price is inc. GST. A tradie who itemises all six is telling you they've done this properly before.
And don't chase the cheapest number. On epoxy more than most trades, the low quote is usually a job with the grinding taken out of it.
