Double Garage Epoxy Flooring Melbourne done properly
A double garage is where epoxy makes the most visible difference. At 36–42m² it is the largest continuous floor in most Melbourne homes, and going from a stained, dusty slab to a seamless flake finish changes how the whole space reads — particularly in newer estates where the garage doubles as storage, gym or workshop.
Larger floors also mean better value per square metre. The fixed costs of a job — mobilisation, grinding setup, edge work — are spread across twice the area, so a double garage typically works out cheaper per m² than a single. Most Melbourne double garages land between $2,400 and $3,200 for a full flake system.
The extra area does change the specification in one important way: expansion joints. Most double garages have a control joint running through the slab, and it has to be treated properly rather than simply coated over. We fill and honour the joint so seasonal slab movement does not telegraph a crack straight through your new floor.
Colour choice matters more at this size too. A large expanse of one dark tone shows every speck of dust; a mid-tone multi-flake blend hides day-to-day use far better. We bring physical flake samples to the inspection so you can see them against your actual light, not on a screen.

Common Questions
Double Garage Epoxy FAQs
Anything not covered here, call 0451 980 606 and we will talk it through.
How much does a double garage epoxy floor cost in Melbourne?
A complete double garage epoxy floor runs $2,400–$2,900 for solid colour and $2,600–$3,400 for a full flake system, based on a typical 36–42m² garage. Metallic finishes range $4,000–$5,600. Those are full installed prices including diamond grinding and polyaspartic topcoat, not per-coat rates.
Is a double garage cheaper per square metre than a single?
Yes. Mobilisation, grinding setup and edge work cost roughly the same whether the floor is 20m² or 40m², so spreading them across a larger area brings the rate per square metre down. A double garage typically works out 15–25% cheaper per m² than a single.
How long does a double garage take?
Two to three days. Day one is grinding and repairs, day two is the base coat and flake broadcast, day three is scraping back and sealing. Foot traffic after 24 hours, vehicles after 5–7 days.
What happens to the joint running through my slab?
It gets filled with a flexible joint filler and honoured through the coating rather than being buried under it. Coating straight over a control joint is a common shortcut, and it is why some epoxy floors develop a dead-straight crack across the middle within a year.
Can you do half the garage at a time so I can keep parking?
We do not recommend it. A cold joint where the two halves meet is visible in the finished floor and creates a weak line. Two to three days of clear access gives a single seamless pour and a far better result.
Which flake colour hides dirt best in a double garage?
A mid-tone blend with mixed flake colours — typically greys with black and white through them. Solid dark tones look striking when clean but show every speck of dust, which is noticeable across a floor this size.
