Epoxy Flooring Cost Calculator

Estimate an installed epoxy flooring budget as an honest low-to-high range — coating system, slab repair, add-ons, and a contingency buffer — instead of a single guessed number. Buildmator’s researched range loads by default; switch to your own local installed rate if you have one. The location-adjusted version applies a state or territory construction-cost proxy based on the available capital-city benchmark.

How to use this calculator

1. Measurement units — square metres or square feet.
2. Area — enter the total, or switch to Calculate from length × width for a live figure.
3. Project type — garage, workshop, commercial, etc. Context for a later quote; it doesn’t change the maths.
4. Coating system — the systems below. Picking one loads its researched per-m² range, with sources named; the self-levelling figure is marked as modeled.
5. Floor condition — how much prep the slab needs. Known work (grinding, crack repair, coating removal) adds cost; an unconfirmed moisture issue only widens the top of the range.
6. Optional add-ons — flakes, a clear topcoat, crack repair, old-coating removal, a moisture barrier. Priced automatically; overlapping selections are disabled so nothing is double-counted.
7. Pricing source — use Buildmator’s researched range, or Enter my local price per m².
8. Contingency allowance — a percentage buffer (default 10%).

The formula

C

estimated installed cost (a low and a high figure)

A

floor area

r_low..high

base coating rate per m², low and high

r_{prep & add-ons}

per-m² rates for the floor-condition adjustment and any add-ons

p

contingency allowance, percent

The effective installed rate shown with the result is the total divided back by area:

A minimum job charge can apply to a small area. The calculator does not add one automatically, so ask the installer whether a minimum changes the result.

On the location-adjusted version, one state or territory construction-cost proxy is applied — exactly once — to researched (not user-entered) pricing. Each factor is based on the available capital-city benchmark, so it is not postcode-level epoxy contractor pricing:

Epoxy system cost per m² (Australia)

Installed supply-and-install, sound slab assumed. The Australian planning ranges draw on SuperTrades’ cost calculator and guide and Floor X Industries’ warehouse-flooring guide. The metallic range averages Metal and Flake, Geelong Concrete Coatings, and Yakka Labour (checked October 13, 2026). Only Yakka explicitly includes GST; confirm the tax and preparation scope of local quotes. Pick a system above to load its researched low-to-high figure; the calculator’s pricing data identifies the source used for each system.

The epoxy flooring cost guide explains what separates these systems.

What adds to the base rate

Brushworks’ epoxy-flooring guide describes how slab condition and preparation affect the installed price (checked August 25, 2026). The calculator applies the following researched or modeled adjustments:

Optional add-ons are priced the same way, and overlapping selections are disabled so nothing is charged twice.

Worked example — flake double garage

36 m² double garage, decorative flake, good slab, 10% contingency:

Worked example — water-based with repair, small area

12 m² utility room, water-based epoxy, “cracks or repairs”, 10% contingency:

The per-m² maths gives roughly $640–$900. A contractor’s total may be higher if a minimum job charge applies; ask rather than assuming a fixed amount.

What actually drives the price

• Slab repair and grinding. A sound, ground slab coats for the base rate; a pitted or cracked one doesn’t.
• Moisture. Moisture moving through a slab can interfere with adhesion. Ask what testing and limits the specified coating requires before assuming a barrier is needed.
• Job size. A minimum charge can affect a small area, while a larger open floor may have a lower rate per m².
• State. Labour and transport vary across NSW, VIC, QLD, WA and the rest. The location-adjusted estimate uses a sourced general construction-cost proxy based on the available capital-city benchmark for each state or territory.

Ways to keep the cost down

• Coat a newer slab before oil, cracks, and an old sealer make prep expensive.
• Ask whether combining a small room with an adjoining area changes the minimum or mobilisation charge.
• Choose flake or solid-colour high-build over metallic for durability without the premium.
• Get itemised quotes — the coating rate is similar; the prep and repair lines aren’t.

Worked planning scenario

Take the illustrative 12 m² room in the worked example above. Its per-m² calculation is roughly $640–$900, but a contractor may apply a minimum job charge that produces a higher quote. The calculator does not add that charge automatically. Ask whether a minimum applies and whether combining an adjoining area into the same scope changes the total; do not assume the larger project will cost only the minimum.

Methodology

Base per-m² ranges draw on the Australian supply-and-install guides linked beside the figures above; the self-levelling figure is modeled. Floor-condition figures reuse researched AUD/m² data where an itemised number exists and a documented percentage of the base rate where it doesn’t. Every result is a planning range, not a quote — see the full methodology; real quotes vary by site, finish, and contractor.
