In short

For an existing garage floor the usual choices are grinding and polishing (about $60–$170 per m²), spray-on resurfacing ($50–$80 per m²) or an epoxy coating; a new floor is priced like any slab.

What garage floors involves

  1. Check the existing slab for cracks, oil and moisture
  2. Grind to open the surface (or break out and re-pour if it's failing)
  3. Repair cracks and joints
  4. Apply the finish: polish, resurfacing, epoxy or sealer
  5. Allow full cure before parking

How much garage floors costs

Prices depend on the slab's condition, size and the finish chosen. Oil-stained or patched floors need more grinding.

Before you hire

  • Ask whether the coating is UV-stable if the garage gets sun
  • Ask for a slip-resistant additive – epoxy and polished floors are slippery when wet
  • Check how hot-tyre pick-up is handled for coatings
  • Fix rising damp first or the coating may lift

Standards and approvals

Cutting, grinding and drilling concrete releases respirable crystalline silica. Under WHS laws the contractor must control the dust (water suppression or on-tool extraction, plus respiratory protection) – ask how they will do it before work starts.

Common questions

Epoxy or polished concrete for a garage?

Polished concrete is very durable and easy to clean; epoxy hides stains and comes in colours but can lift if the slab is damp.

How much does it cost to polish a garage floor?

About $60–$170 per m² for an existing slab, depending on how deep the grind goes and how much patching is needed.

Can a cracked garage floor be resurfaced?

Hairline cracks can be filled and covered. Moving or structural cracks should be checked first – they'll come back through the coating.
