If you are considering Polished Concrete Floors in Perth, one of the first questions to ask is how much the project will cost. The price can vary depending on the size of the area, condition of the existing concrete, level of polishing, aggregate exposure, surface preparation and the finish you choose. Current Perth and Western Australia pricing guides indicate that polished concrete can range from around $65 to $220 per square metre, depending heavily on the specification and finish.
Polished concrete is popular for homes, garages, retail spaces, offices and commercial properties because it combines a contemporary appearance with a hard-wearing surface. However, the cheapest option is not always the right option for every space.
This guide explains the typical costs, the factors that influence pricing, and what to consider before requesting a quote in Perth.
What Does Polished Concrete Cost Per Square Metre?
There is no single price for polished concrete because different polishing systems require different levels of preparation and labour.
As a general 2026 guide, Western Australian pricing can fall into the following ranges:
| Polished Concrete Finish | Indicative Cost Per m² |
|---|---|
| Grind and seal | $65–$110 |
| Mechanically polished concrete | $100–$150 |
| Salt-and-pepper exposure | $120–$180 |
| Full aggregate exposure | $150–$220 |
| Remedial grinding or repairs | $20–$60 extra |
| New slab preparation for polishing | $10–$30 extra |
These figures are indicative rather than fixed quotes. The final price depends on the existing slab, accessibility, floor area, desired appearance and number of grinding and polishing stages required.
Some Perth pricing guides report broader market ranges, with polished concrete around $105–$285 per square metre depending on the project specification. This highlights why comparing quotes based only on the headline per-square-metre figure can be misleading.
What Factors Affect Polished Concrete Pricing?
Several details can change the final price of a polished concrete project. Understanding these factors can make it easier to compare quotes and plan your budget.
Condition of the Existing Concrete Surface
The condition of your concrete has a major impact on preparation costs.
A relatively smooth and sound slab may require less grinding and repair. Older concrete can have cracks, holes, stains, uneven sections, old coatings or adhesive residue that need additional preparation.
If extensive repairs are required before polishing, the additional labour and materials will increase the overall project cost.
Size and Layout of the Flooring Area
The total floor area also affects the price per square metre.
Large, open areas can often be completed more efficiently because equipment can move continuously across the surface. Smaller rooms, narrow areas and floors divided by multiple walls may require more setup and detailed work.
This means a small project may have a higher effective cost per square metre than a larger open-plan floor.
Level of Aggregate Exposure
The amount of aggregate you want to reveal is another important consideration.
A minimal-exposure finish requires less grinding, while salt-and-pepper and full-aggregate finishes involve progressively deeper grinding. Full aggregate exposure can therefore require more work and a higher budget.
The existing concrete also matters because the aggregate beneath the surface cannot always be predicted perfectly without assessing the slab.
Desired Gloss and Finish
Polished concrete can be finished with different levels of sheen, from a subtle satin appearance to a highly reflective surface.
Higher gloss levels generally require additional refinement and polishing stages. If you want a premium decorative finish, discuss the desired appearance with your contractor before work begins so the quote reflects the correct specification.
Is Polished Concrete Different From Grind and Seal?
The terms are sometimes used interchangeably, but they can refer to different finishing processes.
Grind and seal generally involves grinding the concrete surface and applying a protective sealer. It can provide an attractive finished appearance at a lower price point.
Mechanically polished concrete involves progressively refining the concrete surface through multiple grinding and polishing stages to achieve the specified level of smoothness and sheen.
For budget-conscious projects, grind and seal may be worth considering. For a more refined architectural floor, mechanical polishing may be more appropriate.
The right choice depends on where the floor will be used, the appearance you want and how much you are prepared to invest.
How Much Could a Perth Project Cost?
Looking at the per-square-metre rate is useful, but it is also helpful to consider the total project size.
For example, if a contractor quotes $150 per square metre for a particular finish:
| Floor Area | Example Rate | Approximate Flooring Cost |
|---|---|---|
| 30 m² | $150/m² | $4,500 |
| 50 m² | $150/m² | $7,500 |
| 80 m² | $150/m² | $12,000 |
| 100 m² | $150/m² | $15,000 |
These are simple examples rather than fixed Perth project prices. Preparation, repairs, access, edges, existing coatings and the selected finish can all change the final quotation.
For instance, a 100 m² open-plan floor with a good-quality existing slab may have very different preparation requirements from a 100 m² floor that has extensive damage or old flooring adhesive.
Can Existing Concrete Be Polished?
Yes, existing concrete can often be polished, but its suitability needs to be assessed first.
Existing slabs can produce attractive results when the concrete is structurally sound and suitable for grinding. However, cracks, previous repairs, coatings, stains, and uneven surfaces may affect the final appearance.
In some cases, the character of the existing slab becomes part of the finished design. In others, additional preparation may be necessary to achieve a more consistent result.
A professional assessment before work starts can help identify potential issues and prevent unexpected costs.
How Decorative Concrete Can Change Your Budget?
Polished concrete is only one option when upgrading a concrete surface. Homeowners and businesses in Perth can choose from a range of decorative finishes depending on the appearance and performance they want.
Options can include coloured, stencilled, stamped, honed, exposed aggregate and polished finishes. Current Perth guides place many decorative concrete finishes within broad ranges of approximately $75–$150+ per square metre, although premium finishes and complex designs can cost more.
If you are looking for Decorative Concrete Floor Perth solutions, consider more than the initial price. The intended use, maintenance requirements, slip resistance, appearance and expected lifespan should all be part of the decision.
What About Pavers Colouring in Perth?
Concrete decoration is not limited to floors. Existing outdoor areas can also be refreshed through suitable colouring and resurfacing techniques.
Pavers Colouring Perth projects can help change the appearance of tired outdoor surfaces without necessarily replacing the entire paved area. The suitability of colouring depends on the existing pavers, their condition, previous coatings and the desired finish.
Before choosing a treatment, have the surface assessed to determine whether cleaning, repair, colouring, sealing or resurfacing is the most appropriate approach.
Polished Concrete vs Other Flooring Options
Polished concrete is often considered alongside epoxy, tiles, carpet and other flooring systems.
Its main appeal is the combination of a clean modern appearance, durability and relatively straightforward ongoing maintenance. However, the best flooring choice depends on the environment.
For example, an indoor living area may have different requirements from a garage, warehouse, retail space or outdoor entertainment area.
For garages, epoxy flooring can also be an option where a seamless, protective coating is preferred. The suitability of each system should be assessed according to traffic, moisture, chemical exposure, appearance and maintenance requirements.
How to Keep Your Polished Concrete Budget Under Control?
A clear project brief can help prevent unexpected costs.
Before requesting a quote, consider:
- The total floor area in square metres
- Whether the concrete is new or existing
- The condition of the current slab
- The amount of aggregate exposure you want
- Your preferred gloss level
- Whether repairs are required
- Whether old coatings or flooring need removal
- Access to the property
- Any decorative colours or design requirements
- Sealing and ongoing maintenance requirements
It is also worth asking for an itemised quotation. This makes it easier to understand what is included in the price and whether preparation, repairs, sealing and clean-up are included.
