Question 1

How much does epoxy flooring cost in Sydney?

Accepted Answer

Epoxy flooring in Sydney commonly ranges from $25 to $160 per square metre depending on slab condition, preparation depth, selected system, access, and project size. As a guide, solid colour epoxy is usually $25–$60/sqm, flake epoxy $50–$90/sqm, quartz broadcast $65–$110/sqm, and metallic epoxy $100–$160/sqm. Garage projects are often priced as a complete scope, and a Sydney garage epoxy floor commonly ranges from $1,000 to $9,600 depending on size and finish.

Question 2

How long does epoxy flooring take to install?

Accepted Answer

Most residential garage epoxy projects take about 2 to 3 working days once the area is ready: preparation and repairs first, then primer, body or broadcast coats, and final topcoat. Larger commercial or warehouse projects can take around 3 to 7 days or longer if the floor is staged around operations, requires coating removal, or needs extra repairs. Cure time is separate from install time: light foot traffic is usually around 24 hours, full vehicle or forklift use is commonly around 72 hours after the final topcoat, and chemical resistance continues developing over about 7 days.

Question 3

Is epoxy flooring good for garages?

Accepted Answer

Yes, epoxy is a strong option for Sydney garages when the concrete is mechanically prepared and the system is matched to vehicle traffic. A proper garage system can reduce concrete dusting, improve cleanability, resist many oil and tyre marks, and create a more finished space. It is not a shortcut coating: moisture, oil contamination, cracks, old sealers, and cure timing must be handled correctly to reduce peeling, hot-tyre pickup, and early wear.

Question 4

Is epoxy flooring suitable for warehouses?

Accepted Answer

Yes, epoxy can suit warehouses that need dust control, cleanability, chemical resistance, line marking, and a sealed surface for forklift or trolley traffic. The specification should be based on slab condition, forklift turning zones, spill exposure, slip texture, cleaning method, and downtime windows. High-wear aisles, docks, ramps, or staged work areas may need heavier build, quartz or anti-slip aggregate, repairs, or line marking allowances rather than a basic thin coating.

Question 5

What is better: flake, solid colour, quartz, or metallic epoxy?

Accepted Answer

There is no single best epoxy finish. Solid colour is usually the most cost-effective for utility and workshop areas, flake is popular for garages because it hides dust and adds texture, quartz is better for heavier commercial or wet-area grip, and metallic is chosen mainly for premium decorative impact. Surface Master recommends the finish after considering traffic, slip risk, cleaning expectations, UV exposure near doors, budget, and the look you want.

Question 6

Does the concrete need diamond grinding first?

Accepted Answer

In most professional epoxy projects, yes. Diamond grinding removes weak surface laitance, old residue, minor contamination, and sealer films while opening the concrete profile so primer can bond. Acid washing or cleaning alone is not a reliable substitute for most garage, commercial, or warehouse floors. The exact preparation method is confirmed after inspection because heavily contaminated, soft, wet, or previously coated slabs may need extra removal or repair work.

Question 7

Can epoxy be installed over old paint or coating?

Accepted Answer

Epoxy should not be installed over loose, failed, contaminated, unknown, or incompatible paint or coatings. Those layers normally need mechanical removal back to clean, profiled concrete before the new system is applied. A sound compatible coating may sometimes be abraded and recoated, but this is confirmed by inspection and adhesion risk, not assumed. Coating over weak old paint is one of the fastest ways to cause peeling or delamination.

Question 8

How soon can cars drive on a garage epoxy floor?

Accepted Answer

Vehicle return is system-dependent, but many residential garage epoxy systems need around 72 hours after the final topcoat before cars drive or park on the floor. Light foot traffic is commonly possible after about 24 hours, while full chemical resistance develops over about 7 days. Always follow the written handover for your specific products, weather conditions, slab temperature, and topcoat because early vehicle traffic can mark or damage uncured coatings.
