## What affects Polished Concrete cost

- **Finish level:** The biggest driver of polished concrete floors price is the finish you choose. Grind & seal starts at $65/m², salt & pepper is $95/m², full aggregate exposure is $140/m², and decorative coloured or patterned finishes reach $175/m².
- **Condition of the existing slab:** If the slab is already in good condition, you pay the standard rate for your chosen finish. If it needs repair, add $20/m² before multiplying by the floor area, which can significantly increase the polished concrete cost per m2.
- **Floor area:** Concrete polishing cost per square metre is applied across the total floor area, so larger spaces naturally cost more overall. However, there is also a minimum job charge of $2500 AUD if the calculated amount falls below that figure.
- **Estimate range:** Displayed estimates are shown as a range using ±15% around the midpoint rate. This means the final polished concrete floors price per square metre may vary within that band depending on job specifics and site conditions.

## Frequently asked questions

### What is the average polished concrete cost per m2 in Australia?

Polished concrete cost per m2 generally starts at $65/m² AUD for a grind & seal matte finish and goes up to $175/m² AUD for decorative coloured or patterned concrete. Mid-range options include $95/m² for salt & pepper and $140/m² for full aggregate exposure. If the slab needs repair, add $20/m² to those rates before calculating the total.

### How does slab condition affect polished cement floors cost?

Polished cement floors cost is lower when the existing slab is in good condition because you only pay the base finish rate. If repairs are required, add $20/m² to the chosen finish before multiplying by the area. For example, a $95/m² salt & pepper finish becomes $115/m² when slab repair is needed.

### What is the minimum polished concrete price for small jobs?

There is a minimum job charge of $2500 AUD when the calculated polished concrete price falls below that amount. This means very small areas may not simply be charged at the per-square-metre rate alone. The minimum helps cover setup, labour and equipment costs.

### How is concrete polishing cost per square metre turned into a total estimate?

The total is calculated by taking the concrete polishing cost per square metre for your selected finish, adding $20/m² if the slab needs repair, and then multiplying by the floor area. After that, the displayed estimate range is shown at ±15% around the midpoint. If the result is below $2500 AUD, the minimum job charge applies instead.
