Quick answer
Across Australia, professionally installed epoxy floors typically run from about A$55 to A$180 per square metre depending on the system, with a double garage commonly landing between roughly A$2,000 and A$6,500. These are general market ranges, not Adelaide Epoxy prices. The biggest cost drivers are slab condition, preparation, system type and access, so a free on-site quote is the only reliable number.

Typical Australian price ranges by system
| System | Typical range (A$ per m²) | Typical 36 m² double garage (A$) | Notes |
|---|---|---|---|
| Solid-colour epoxy on ground slab | A$45 – A$85 | A$1,600 – A$3,100 | Simplest build; shows tyre marks and dust more than flake. |
| Flake epoxy, full broadcast | A$55 – A$110 | A$2,000 – A$4,000 | The most common garage system; hides dirt well. |
| Metallic epoxy | A$90 – A$180 | A$3,200 – A$6,500 | Decorative; needs flatter slab and more labour. |
| Polyaspartic topcoat system | A$80 – A$150 | A$2,900 – A$5,400 | Fast-cure and UV-stable; can cost more for materials. |
| Commercial and industrial build | A$45 – A$120 | Varies with area | Depends heavily on thickness, coving and line marking. |
Why such wide ranges? Because epoxy flooring is a layered system installed on a surface that is different in every building. A clean, flat, sound double-garage slab is at the cheap end of the table; a patched, oil-soaked slab with a failed coating to remove and lots of cracks is at the expensive end, even if the finished floor looks identical.
What drives the cost of an epoxy floor
Floor area
Price per square metre falls slightly as the area rises, because setup, travel and mobilisation are spread over more floor. A single garage of around 18 square metres may cost more per metre than a large shed, though the total is smaller. Always ask for both the total and the rate per metre so you can compare like with like.
Surface preparation
Preparation is where cheap and good quotes diverge. Diamond grinding, dust extraction, crack and joint repair, oil treatment and moisture checks take time and equipment. When a price is dramatically lower than the others, the missing line item is usually preparation, and that is also the most common reason coatings peel. Our prep and warranty guide lists what a proper scope contains. Grinding alone is sometimes itemised at roughly A$10 to A$30 per square metre on the Australian market.
System choice and number of coats
A single thin coat of solid colour is cheaper than a base coat, full flake broadcast and two clear topcoats. A decorative metallic floor adds pigment, labour time and usually a thicker clear coat. Faster-curing polyaspartic topcoats add material cost but may reduce downtime. See flake versus metallic and epoxy versus polyaspartic to understand what you gain for the extra money.
Slab condition and repairs
Cracks, spalling, old paint, rising damp and soft concrete all add work. Repairing a few hairline cracks is a small item; rebuilding a broken threshold or chasing moisture is not. The cost of repairs is worth paying because coating over a weak substrate is how floors fail.
Access, location and timing
A tight inner-suburban garage with a narrow driveway takes longer than an open shed in the same area. Travel to the Adelaide Hills, the Fleurieu or the Barossa adds time. Hot-day scheduling, such as an early start to beat the heat, can also change the job plan; the Adelaide climate guide covers why.
A worked example with ranges
Suppose you have a 36 square metre double garage with an oil patch, a few hairline cracks and an old paint finish. Based on the typical ranges above, a full-broadcast flake floor might sit around A$2,000 to A$4,000 for a clean slab, and somewhere nearer the upper end if grinding off paint and treating oil are both needed. A metallic floor on the same slab would sit higher, say A$3,200 to A$6,500 or more. Those are market-wide ranges, not what Adelaide Epoxy would charge; the on-site assessment determines that.
Cheap quotes and DIY kits
DIY kits can look attractive at A$300 to A$800 for a garage, but thin kit coatings often peel within a season, particularly under hot tyres, and they are rarely supplied with industrial grinding gear. The cost of grinding off a failed DIY kit before a professional coating is often the real price of the experiment. See epoxy versus floor paint for a detailed comparison.
How to compare quotes fairly
- Ask each contractor to list the preparation method: grinding, shot-blasting, or acid etching.
- Confirm the number of coats, the flake coverage and the topcoat type in writing.
- Check what happens to cracks, joints and oil patches.
- Ask about moisture testing and how it affects the warranty.
- Compare the written workmanship terms, not just the headline price.
Frequently asked questions
How much does a double garage epoxy floor cost in Adelaide?
General Australian market ranges suggest roughly A$2,000 to A$6,500 for a 36 square metre double garage, depending on the system and slab condition. Adelaide Epoxy gives written quotes after a free on-site assessment.
Why is metallic epoxy dearer than flake?
Metallic needs a flatter slab, more labour, expensive pigments and a skilled hand, and it is usually finished with a thicker clear coat.
Do you publish fixed prices?
No. Every slab is different, so we quote after seeing the floor.
Is the cheapest quote a good sign?
Rarely. The difference is most often in preparation, which is what decides how long the floor lasts.
