How much does polished concrete cost per square metre in Australia in 2026?

Most residential polished concrete jobs in Australia fall between $80 and $150 per m² for the grind-and-polish work. A basic cream polish sits at the lower end, while a full aggregate exposure with deep gloss is at the higher end. These figures are general market ranges. A written quote from a local contractor is essential for an accurate price on your specific job.

Is polished concrete cheaper than tiles or timber flooring?

It depends on the finish and the existing slab condition. On a per-m² basis, polished concrete can be comparable to mid-range tiles or engineered timber once you factor in installation. If you already have a suitable concrete slab, you avoid the cost of a new subfloor or adhesive. Polished concrete also tends to have lower long-term maintenance costs than timber.

Can any concrete slab be polished?

Most slabs can be polished, but not all will achieve the same result. Very soft or contaminated concrete, slabs with significant cracking, or those with too much surface variation may limit the finish options. A cream polish is achievable on most slabs. Full aggregate exposure requires the original pour to have enough suitable aggregate in the mix. A contractor should inspect and ideally do a test grind before quoting a specific finish.

How long does polished concrete take to complete?

A typical residential job of 50 to 80 m² usually takes two to four days depending on the finish level, number of grinding passes and drying times between densifier and sealer coats. Larger commercial floors can take longer. You will need to stay off the floor for at least 24 hours after the final sealer is applied, sometimes longer.

Does polished concrete add value to a home?

Polished concrete is popular in new builds and renovations, particularly in open-plan living areas and commercial fit-outs. It is viewed positively by many buyers for its durability and modern look. Whether it adds measurable resale value depends on the quality of the finish and local buyer preferences. In some markets it is considered a premium feature; in others it may not suit the majority of buyers.

What is the difference between polished concrete and concrete overlay?

Polished concrete involves grinding back the existing slab surface to expose and refine the concrete itself. A concrete overlay involves applying a thin layer of specialised cementitious product over an existing floor, which is then polished or textured. Overlays are often used where the base slab is in poor condition or where a specific colour or finish is required. Overlays can cost a similar amount per m² but the process and durability profile differ. Ask your contractor which approach suits your slab.

Is polished concrete slippery?

A high-gloss polished concrete floor can be slippery when wet, which is worth considering for wet areas, laundries or outdoor-adjacent spaces. A matte or satin topcoat reduces slip risk compared to a high-gloss finish. Anti-slip additives can be mixed into the sealer. Discuss slip ratings with your contractor, particularly for commercial spaces where Australian standards for slip resistance apply.

Polished Concrete Prices at a Glance

Polished concrete in Australia typically costs $80 to $150 per m² for a grind-and-polish finish, supplied and laid. The final figure depends heavily on the number of grinding passes (cream, salt-and-pepper or full aggregate exposure), the condition of the existing slab, and the level of sheen you want. Minimum job costs usually start around $1,500 to $2,000 regardless of area.

Those numbers cover the core grinding and polishing work. They do not always include slab repair, densifier application, crack filling or a topcoat sealer, all of which add to the invoice. Always read the quote line by line before signing anything.

Prices vary between states. Sydney and Melbourne tradespeople generally sit at the higher end due to labour and operating costs. Regional Queensland, South Australia and Western Australia can be cheaper, though travel charges may apply in outer suburban or rural areas.

Cost by Finish Level

Polished concrete is not a single product. The industry broadly breaks it into finish levels based on how far the grinding process goes and the final gloss. Each step up adds time, diamond tooling cost and labour.

Finish Level	Description	Typical Cost (per m²)
Cream polish (Level 1-2)	Light grind, minimal aggregate exposure, low to medium sheen	$80 - $100
Salt-and-pepper (Level 2-3)	Medium grind, fine aggregate visible, medium to high sheen	$100 - $120
Full aggregate exposure (Level 3-4)	Deep grind, coarse stones exposed, high gloss or matte topcoat	$120 - $150
Existing slab (retrofit polish)	Grinding back a cured slab, price depends on slab condition	$80 - $150

These are general market ranges. Your actual quote will reflect the specific slab, room size, access and the contractor's overhead. A written quote is the only reliable price.

If you are pouring a new slab specifically for polishing, tell the concreter upfront. The mix design, finishing technique and curing method all affect how well the slab polishes later. A slab poured with polishing in mind can be cheaper to polish than one that was not.

What Drives the Cost Up (or Down)

Slab Condition

Retrofitting an older slab is often the biggest cost variable. Cracks, contamination, previous coatings, paint, adhesive residue or uneven surfaces all require extra prep. A contractor may need to grind out low spots, fill cracks with epoxy filler and do a test grind before committing to a finish price. Budget extra if your slab has seen years of warehouse or garage use.

Area and Room Shape

Larger open areas are more cost-efficient per square metre than small, broken-up rooms. Hallways, bathrooms and rooms with lots of cabinetry or pillars increase the cutting time around edges. Some contractors charge a higher rate per m² for jobs under 30 m² because setup, travel and equipment time does not scale down proportionally.

Number of Grinding Passes

A full aggregate exposure finish requires multiple diamond grinding passes, working from coarse to fine grits. That is more time and more tooling wear. A cream polish needs fewer passes. The difference in labour alone can be $20 to $40 per m² between the two extremes.

Densifier and Sealer

A lithium or sodium silicate densifier is standard practice, chemically hardening the surface before final polishing. A topcoat sealer adds another layer of protection and sheen control. Both are often quoted as separate line items. Sealing alone can add $15 to $30 per m² depending on the product used.

Dye or Colour

Integral dyes or reactive stains can be applied during the polishing process to add colour. This typically adds $15 to $40 per m² depending on the dye type and how many coats are needed.

State and Location

Labour rates in Sydney, Melbourne and Perth CBDs are generally higher than in regional areas. That said, regional jobs may carry travel or accommodation costs if specialised polishing equipment needs to be transported. Always check whether travel is included in the quote.

Be cautious of very low quotes that do not specify the number of grinding passes or the products used. A cheap polish that skips key steps, particularly densifying, will wear poorly and may need to be redone within a few years. Ask the contractor to detail the process step by step.

New Slab vs Existing Slab: Cost Comparison

Many homeowners and builders ask whether it is cheaper to polish a new slab or an existing one. The answer depends on what you are starting with.

Scenario	Typical Combined Cost (per m²)	Notes
New slab poured for polishing + polish finish	$160 - $260	Slab at $80-$110 + polishing at $80-$150. New slab allows correct mix design.
Existing domestic slab in good condition	$80 - $130	Minimal prep needed. Finish level depends on aggregate in original pour.
Existing slab with damage or coatings	$100 - $180+	Allow for crack repair, coating removal and possible patching.
Commercial warehouse or industrial slab	$50 - $100	Large open areas reduce per-m² cost. Fewer edge cuts.

Commercial and industrial polishing often comes in cheaper per square metre because the economies of scale are real. A 500 m² warehouse floor is a very different job from a 60 m² open-plan kitchen and living area.

Maintenance and Long-Term Costs

Polished concrete is frequently chosen because it is durable and relatively low maintenance compared to timber or carpet. That is mostly true, but it is not maintenance-free.

Resealing

Topcoat sealers on polished concrete typically need reapplication every two to five years depending on foot traffic and cleaning products used. Resealing a domestic floor generally costs $15 to $30 per m² for the product and labour, though this varies by contractor and the product specified.

Repairs

Surface scratches and scuffs can often be buffed out with a low-speed polisher. Deeper damage may need localised regrinding. If the floor was not properly densified, it may start to dust or degrade. Budget for periodic maintenance if the floor is in a high-traffic area.

Cleaning

Polished concrete should be cleaned with a neutral-pH cleaner. Acidic cleaners, bleach and strong degreasers can etch the surface or strip the sealer. This is not an extra cost, just a product swap. Many contractors will recommend specific products when they hand over the job.

How to Get and Compare Quotes

Getting three quotes is the standard advice for a reason. Polished concrete pricing varies more than most concreting work because the process has so many variables. Here is how to make comparisons meaningful.

What to Ask Each Contractor

How many grinding passes will be done, and what grit sequence?
Is a densifier included? Which product?
Is a topcoat sealer included? What sheen level?
What is the plan for cracks or damaged areas?
Is prep work (moving furniture, removing existing floor coverings) included or extra?
What is the warranty on the finish?

Compare Line by Line

A quote for $95 per m² that includes densifying, sealing and crack repair is better value than $80 per m² that covers grinding only. Do not compare totals until you know what each quote actually covers.

Check Experience with Your Finish

Ask to see photos or, better, completed jobs in your area. Full aggregate exposure on a salt-and-pepper finish is a skilled process. Not every concreter who advertises polished concrete has done a lot of it. References matter.

Polished concrete costs between $80 and $150 per m² for most residential work in Australia in 2026. The finish level, slab condition and job size are the main price drivers. Get at least three detailed, written quotes before committing, and make sure each one specifies exactly what the process includes.
