The first question almost every Melbourne homeowner asks when they ring us about a garage floor is simple: “Just give me a rough number.” Fair enough. So whether you’ve searched how much for epoxy flooring or how much is epoxy flooring in Melbourne, here it is up front — epoxy flooring in Melbourne typically costs $45 to $120 per square metre installed, which puts a standard single garage somewhere around $1,600 to $3,500 depending on the system and the state of the slab. That range is wide for a reason, and by the end of this guide you’ll know exactly where your own floor sits within it.
We’ve laid epoxy over cracked 1970s garage slabs in Sunshine, fresh pours in new Point Cook builds, and warehouse floors out west that took three days of grinding before a drop of resin went down. The price gap between those jobs wasn’t the epoxy — it was everything underneath. This guide walks you through what actually drives an epoxy flooring cost so you can read a quote properly and spot when one’s too good to be true. If you’d rather just talk it through, our team is happy to give you a free, no-obligation quote.
What Does Epoxy Flooring Cost Per m² in Melbourne?
Epoxy flooring in Melbourne generally runs between $45 and $120 per square metre installed, with most residential garage jobs landing around $60 to $90 per m². If you’ve searched epoxy flooring cost per m2 Australia-wide to compare states, Melbourne prices sit squarely within that national range, with the same drivers — slab condition and system — explaining most of the difference wherever you are. The figure depends mainly on the coating system you choose and how much prep the concrete needs before coating.
Here’s how the common systems compare:
| Epoxy system | Typical cost per m² (installed) | Best suited to |
|---|---|---|
| Basic roll-on epoxy coating | $45 – $65 | Budget garages, low traffic |
| Flake / speckle epoxy system | $65 – $90 | Most home garages, workshops |
| Metallic / decorative epoxy | $90 – $120 | Feature floors, showrooms, alfresco |
| Commercial / industrial build-up | $80 – $150+ | Warehouses, factories, high load |
A quick reality check on the cheap end: a $40/m² “epoxy” quote is often a single-coat garage paint, not a true two-part epoxy system. It’ll look great for a summer, then lift at the tyre contact points once a hot car sits on it. The gap between $45 and $90 is usually the difference between one thin coat and a properly primed, multi-coat, sealed floor. That distinction matters more than the brand on the bucket.
How Much to Epoxy a Garage Floor?
A standard single garage in Melbourne (roughly 18–20 m²) costs about $1,600 to $3,500 to epoxy, while a double garage (36–40 m²) typically runs $2,800 to $6,000. The bigger the floor, the lower the per-m² rate usually drops, because the mobilisation and grinding setup is spread across more area.
Rough real-world figures we see across Melbourne:
- Single garage (18–20 m²): $1,600 – $3,500
- Double garage (36–40 m²): $2,800 – $6,000
- Triple garage / large shed (55 m²+): $4,500 – $9,000+
- Small alfresco or laundry (8–12 m²): $900 – $1,800
Those numbers assume a slab in reasonable condition. Where budgets blow out is the surface underneath — which brings us to the single biggest cost driver most people never think about.
What Changes the Final Quote?
The epoxy resin itself is a small slice of the price. What moves your quote up or down is the concrete prep, the condition of the slab, and the finish you choose. Here’s what we’re actually pricing when we walk your garage.
Concrete preparation and slab condition
This is the number-one cost factor, full stop. Epoxy only bonds to properly prepared concrete. If the slab is sealed, oily, or glazed, it has to be mechanically opened up first — usually by diamond grinding. A clean, bare, newish slab might need a light grind; an old garage with oil stains, paint, and a sealer on top can need aggressive grinding across the whole floor. That labour alone can add $15–$30 per m².
Moisture is the other silent killer. Melbourne slabs on ground, especially in older western-suburb homes, can push moisture up through the concrete and lift an epoxy coat months later. A proper contractor tests for this and applies a moisture-barrier primer if needed — an extra step, but far cheaper than re-doing a failed floor.
Crack and pit repair
Cracks, spalling, and pitting all have to be filled and cured before coating, or they telegraph straight through the finish. A few hairline cracks are minor; a slab with concrete cancer or significant movement cracks needs real repair work first. If your slab is in rough shape, it’s worth reading up on the full range of surface and concrete services before you commit to a coating.
The finish and flake coverage
A plain solid-colour coat is the cheapest. Add decorative flake (the speckled look) and you’re paying for the flake, plus a clear topcoat to lock it in — full “broadcast” coverage where flake covers the entire floor costs more than a light scatter. Metallic epoxy, with its marbled pigment effect, is the most labour-intensive and sits at the top of the range.
If you’re mid-way through pricing a bigger renovation, it’s worth lining your floor budget up against your other rooms — our Melbourne house painting cost guide covers interior and exterior figures so the whole project stays consistent.
Access, size, and location
A ground-floor double garage with a wide roller door is easy. A narrow single with limited access, a first-floor space, or a job an hour from our base carries a bit more in setup and travel. Larger floors bring the per-m² rate down; tiny awkward floors push it up.
Is Epoxy Flooring Worth the Cost?
For most Melbourne garages, yes — a properly installed epoxy floor lasts 10 to 20 years, resists oil, chemicals and hot tyres, and wipes clean with a mop. Compared with re-sealing bare concrete every few years or living with a dusting, staining slab, the up-front cost usually pays for itself in durability and resale appeal.
The key word is “properly installed.” A rushed single-coat job over an unprepared slab can fail inside a year, which is where epoxy gets its occasional bad reputation. Spend on the prep, not just the pretty topcoat, and a good floor will outlast several cars.
A quick checklist before you accept any epoxy quote
- Does the quote spell out the prep method (diamond grinding vs. just a wash)?
- How many coats, and is there a dedicated primer and clear topcoat?
- Is moisture testing mentioned for older or ground-level slabs?
- Are crack and pit repairs included or listed as an extra?
- Is it a genuine two-part epoxy system, or a single-coat garage paint?
If a quote skips prep and coats entirely and just gives you a headline m² price, that’s your cue to ask more questions.

Frequently Asked Questions
Getting a Real Number for Your Floor
Epoxy flooring cost comes down to three things: the system you pick, the size of the floor, and—above all—the condition of the slab underneath. A healthy slab with a straightforward flake system will sit comfortably in the mid-range; an old, cracked, oil-stained garage that needs heavy grinding and moisture control will cost more, and it should. The floors that fail are almost always the ones where someone skipped the prep to win the job on price.
The only way to know where your floor lands is to have someone look at the actual concrete. We’re happy to come out, assess the slab honestly, and give you a clear, itemised quote with no pressure—so you can see exactly what you’re paying for.
