Every second phone call we get starts the same way: "roughly, what's this going to cost me?" It's a fair question, and it deserves a real answer instead of "every job is different," even though every job genuinely is a bit different. So here's what actually moves the number, and the price ranges we quote across Sydney for garages, driveways, metallic finishes and commercial floors.
What actually drives the cost of epoxy flooring
Two epoxy quotes can look completely different on paper and be for completely different jobs underneath. Before you compare numbers, it helps to know what you're actually paying for.
- Surface preparation. Mechanical diamond grinding opens up the concrete and gives the epoxy something to physically bond to. Skip it, and the coating sits on top of the slab instead of gripping it. This is the single biggest reason a cheap floor fails within a couple of years.
- Number of coats. We run 5-6 coat systems as standard. Some quotes you'll see are for 2-3 coats, which costs less upfront and shows within the first year.
- Size and shape of the area. A single garage, a double garage and an L-shaped warehouse floor all price differently, and awkward shapes with lots of cutting-in cost more per square metre than a simple rectangle.
- Finish type. Plain colour is the cheapest way in. Full flake broadcast sits in the middle. Metallic and marble-effect finishes cost more because of the hand-swirling technique and the extra time it takes.
- Condition of the existing slab. Cracks, old paint, oil staining or a previous coating that needs stripping all add labour before the actual epoxy system goes down.
Garage floor epoxy cost in Sydney
Garage floors are the job we quote most often, and they're priced as a flat rate for the space rather than per square metre, since the prep and coat count don't change much from one garage to the next.
| Garage size | Full flake system (incl. diamond grinding) |
|---|---|
| Single garage | $1,200 – $2,200 |
| Double garage | $2,200 – $4,000 |
Where you land in that range comes down to slab condition and how much cutting-in there is around shelving, stairs or an internal door. A clean, crack-free double garage in a newer estate in Marsden Park is usually a straightforward quote. An older single garage on a Federation-era block in the Inner West with an uneven slab and a step down at the door takes more prep time, and the price reflects that.
Metallic and marble epoxy cost
Metallic and marble-effect epoxy start from $4,000. It's a genuinely different process to a standard flake floor: pigments are hand-swirled through the wet epoxy to create the veined, three-dimensional look, and no two floors come out the same. That hand technique takes longer than broadcasting flake, which is where the extra cost comes from. See our full guide to metallic epoxy flooring for how the process actually works.
Driveway epoxy coating cost
Driveways are quoted per square metre because driveway sizes vary so much, from a single-car strip on an inner-city terrace to a wide double driveway on a new build.
As a rough guide, driveway coatings run $65 – $120 per square metre depending on the system. A single driveway around 40–60m² commonly lands at $3,000 – $6,000. Durastone and polyaspartic finishes sit toward the top of that range; plain sealed systems sit toward the bottom.

Commercial and industrial epoxy flooring cost
Commercial jobs, warehouses, showrooms, retail fitouts, typically run $45 – $90+ per square metre, depending on slab condition, system thickness and extras like line marking. Industrial and ESD (anti-static) flooring for factories and electronics environments runs a bit higher again, generally $50 – $100+ per square metre, because those systems often need higher-build thickness or specialised conductive properties. We cover the full picture, including what "forklift rated" actually means, in our commercial and industrial epoxy guide.
What businesses in industrial suburbs are quoted
If you're in one of Sydney's manufacturing and logistics hubs, like Smithfield or Wetherill Park, the quote usually depends more on compliance requirements (chemical resistance, static control, line marking for forklift lanes) than on the size of the warehouse alone. Two units of the same square footage can price differently once you factor in what the floor actually needs to do.
Why the cheapest quote usually costs more in the end
DIY epoxy kits and the cheapest trade quotes both tend to use thin, water-based products applied over a slab that hasn't been properly ground. They look fine for six to twelve months, then start peeling at the edges and around tyre marks. We use commercial-grade 100% solids epoxy applied in 5-6 coats over a diamond-ground slab, which is why a properly installed floor holds up for 15 to 20-plus years under normal residential use instead of needing a redo within a couple of seasons.
If you're comparing a DIY kit or a budget quote against ours and the number looks a long way apart, ask what's included in the prep and how many coats you're actually getting. That's usually where the difference lives.
Getting an accurate price for your property
Every one of these ranges is a starting point, not a final number. The only way to get an exact figure is a free on-site quote, where we look at your actual slab, measure the space, and talk through finish options. There's no call-out fee and no obligation, and most Sydney jobs we quote start within the week.
