If you’ve searched “epoxy flooring price” recently, you’ve probably noticed something frustrating. One site tells you $30 a square metre. Another says $150. A tradie you called last week quoted somewhere in between, with no real explanation of why. It’s enough to make anyone give up and just repaint the garage with whatever’s on the shelf at the hardware store.
Here’s the thing. Those numbers aren’t lies, they’re just answering different questions. A basic single coat over a clean slab and a full decorative flake system over a cracked, oil stained floor are two completely different jobs, even though they both fall under “epoxy flooring”. In Melbourne specifically, where older garages often carry years of tyre marks and damp concrete, the real garage epoxy floor cost depends on a handful of specific factors most quotes never spell out. Let’s go through them properly.
How Much Does Garage Epoxy Flooring Actually Cost?
For a Melbourne garage in 2026, you’re generally looking at somewhere between $80 and $150 per square metre for a proper professional installation, including prep, primer, base coat and topcoat. A basic single coat system without much decorative finish can sit closer to the $50 to $80 mark, while a full flake or metallic system with heavy prep work can push toward $150 or occasionally higher.
In real terms, that means:
- A single garage (around 18 to 20 square metres) typically lands between $1,200 and $2,500 all up.
- A double garage (around 36 to 40 square metres) usually comes in between $2,200 and $4,500.
Those ranges are wide on purpose. The next few sections explain exactly why.
What’s Included (and What Isn’t) in a Standard Quote
A proper quote should cover four stages: surface preparation, primer, a base coat, and a topcoat. Prep is where a lot of the cost hides. That means diamond grinding the concrete to open up the surface so the epoxy actually bonds, rather than just sitting on top and peeling off within a year.
What often gets added as an “extra” once someone’s actually looked at your floor:
- Crack repair, if the slab has movement cracks or chips
- Moisture testing, especially important in older Melbourne garages where rising damp is common
- Degreasing, for floors that have had years of oil and fluid drips soaked into the concrete
- Additional grinding passes, if the existing surface is uneven or has old paint that needs stripping back
None of this is a scam. It’s just work that a photo or a phone quote can’t account for. If a quote seems unusually low, it’s worth asking directly what prep is included, because that’s usually where the gap comes from.
Why Epoxy Resin Floor Costs Vary So Much Between Quotes
A few things genuinely move the number:
Concrete condition. A clean, sound slab with no cracking or old coatings is the cheapest scenario. A garage with failed paint, oil staining or moisture issues needs more grinding and prep time, which adds cost before a drop of epoxy goes down.
Removing existing coatings. If your garage already has old paint or a failed epoxy job, that has to come off first. This adds labour hours that a bare slab wouldn’t need.
Size. Larger areas generally cost less per square metre because the setup and prep time gets spread across more coverage. A tiny space can actually cost more per metre than a full double garage.
Colour and flake systems versus plain. A solid colour, two coat system is cheaper than a broadcast flake or metallic finish, which involves extra layers and more application time.
Two coat versus three coat systems. More coats mean more durability, particularly useful if you’re parking heavy vehicles or doing mechanical work in the garage, but it also means more material and labour.
DIY Epoxy Kits vs Professional Installation Cost
A DIY epoxy kit from a hardware store usually costs somewhere between $100 and $400 for a single garage. On paper, that looks like an easy win against a $1,200 to $2,500 professional job.
In practice, most DIY kits are water based paints rather than true two pack epoxy systems, and they behave very differently under real garage conditions. Hot tyres are a common failure point. A car that’s been driving on a hot day and pulls into the garage can literally lift the coating where the tyre sits, known as hot tyre pickup. Moisture bubbling is another common issue, especially on slabs without a proper vapour barrier underneath.
Most DIY jobs that fail do so within one to two years, at which point the floor needs to be ground back and redone properly anyway, often at a higher cost than if it had been done professionally from the start. A professional two pack epoxy system, properly prepped and applied, typically holds up for 5 to 10 years or more with basic care.
Cost of Epoxy Flooring for Other Areas vs Garage
Garages get most of the attention, but the same system works well in other parts of the house. Alfresco areas usually sit in a similar price bracket to garages, sometimes slightly higher if UV stable topcoats are needed to handle direct sun exposure. Workshop floors, particularly if they’re seeing heavy tool use or chemical exposure, often go with a thicker three coat system, which pushes the cost up a bit. Basement floors can vary a lot depending on moisture levels, since below ground concrete in older Melbourne homes sometimes needs a moisture barrier added before the epoxy goes down.
If you’re getting the garage done, it’s worth asking about a package rate for these other areas at the same time. Preparation crews and materials are already on site, so combining jobs can bring the per metre rate down slightly.
How to Get an Accurate Floor Installation Cost Quote
A few things worth doing before you commit to anyone:
- Ask for an on-site inspection rather than a quote based on photos or a phone description. Concrete conditions are genuinely hard to assess remotely.
- Get a breakdown of what’s included, specifically prep work, number of coats, and topcoat type.
- Ask what happens if the crew finds additional cracking or moisture once grinding starts, and whether that’s charged as a variation or included in the original price.
- Treat unusually low quotes with some caution. If a number is well below the range above, ask directly what’s being left out.
A good installer won’t mind these questions. If anything, they’ll usually bring them up before you ask.
FAQs
How much does it cost to epoxy a garage floor in Melbourne? Most Melbourne garages cost between $80 and $150 per square metre for a professional job, including prep and topcoat. A single garage typically totals $1,200 to $2,500, while a double garage runs $2,200 to $4,500, depending on concrete condition and finish choice.
Is epoxy flooring cheaper than DIY floor paint long-term? DIY kits cost less upfront, usually $100 to $400, but they commonly fail within one to two years due to hot tyre pickup or moisture bubbling. Once you factor in redoing the floor properly afterward, professional epoxy is usually the cheaper option over time.
What affects the price of epoxy resin flooring the most? Concrete conditions have the biggest impact. Cracks, old coatings, oil staining and moisture issues all add preparation time. Size, coat count, and whether you choose a plain colour or a decorative flake system also play a role.
How long does a garage epoxy floor coating last? A properly installed professional system typically lasts 5 to 10 years or longer with basic care, such as regular sweeping and avoiding harsh chemical spills sitting on the surface too long.
Do I need to repair concrete cracks before epoxy coating? Yes, in most cases. Cracks left untreated tend to telegraph through the epoxy over time and can compromise how well the coating bonds. A proper quote should include crack repair as part of the prep stage.
Can I get a fixed price quote or only an estimate? Once an installer has physically inspected the concrete, most will provide a fixed price rather than a rough estimate. Online calculators and phone quotes can only give a ballpark, since the final number depends on what the slab actually needs.
