The real cost of an epoxy garage floor in Sydney
Garage floors are the one job where the per-metre rate misleads people most, because the floor is small and the setup is not. Here is how the pricing really works.
The numbers first
Published Sydney pricing for professionally installed epoxy flake floors clusters tightly:
| Job | Typical market range |
|---|---|
| Single garage (roughly 14-20 m²) | $1,850-$2,500 |
| Double garage (roughly 28-40 m²) | $2,150-$4,200 |
| Premium full flake, per square metre | $85-$95 |
Market figures from published Sydney installer pricing, not our price list. We quote on site after seeing the slab.
Why small floors break the per-metre logic
A garage is usually 15 to 40 square metres. The grinder, the dust extraction, the materials, the travel and the return visits for each coat cost roughly the same whether the floor is small or large, so the fixed costs dominate and the per-metre rate climbs as the floor shrinks.
This is why a single garage at $1,850 and a double at $2,350 are both fair prices even though the double has twice the area. Judge garage quotes by the total, not the rate.
Flake or roll coat, and what the difference costs
A full flake system broadcasts coloured vinyl chips into the wet coating and locks them under a clear topcoat. It is the speckled, showroom finish most people picture, it hides dust and marks well, and it is the more expensive option. Cookies and cream is consistently the most requested colour we do.
A roll coat is a single-colour coating without the flake. It is cleaner-looking, cheaper, and entirely fit for a shed or storage area, though it shows marks sooner than flake does. Both are covered on our epoxy flooring page.
What separates a $2,000 floor from a $3,500 one
On the same size garage, the spread between quotes usually comes down to four things:
- Preparation. Mechanical grinding with dust extraction costs more than acid etching or a quick wash, and it is the single biggest predictor of whether the coating stays down.
- Repairs. Cracks, oil-saturated patches and spalled edges need attention before coating, and some floors need a lot of it.
- The system itself. Thicker builds, moisture barriers and polyurethane or polyaspartic topcoats cost more than a thin single coat.
- Edges and details. Taking the finish wall to wall, up the step and into corners takes time that a floor-only quote skips.
About those $400 DIY kits
Hardware store epoxy kits exist, and the price difference is real. So is the difference in what you get, which is why we wrote a separate honest piece on why DIY epoxy kits peel and when they are still worth it. The short version: the kit is not the problem, the preparation you cannot do with a rented pressure washer is.
Getting a real number for your garage
Damien looks at the slab, checks for moisture and old coatings, measures up and gives you a firm written price. If the honest answer is that a roll coat will do the job for less, that is what you will hear.
