Perth coloured concrete price bands
| Band | $/m² (supplied and installed) | What puts a job in this band |
|---|---|---|
| Low | $100–$120 / m² | Integral oxide in standard colours (charcoal, terracotta, sandstone, buff), plain slab, straightforward access, single sealer coat. Common for driveways and paths. |
| Mid | $120–$145 / m² | Custom colour blend or dry-shake hardener finish, exposed aggregate or lightly textured surface, two-coat UV-stable sealer. Most common band for coloured driveway and alfresco pours. |
| High | $145–$170 / m² | Chemical acid-stain finish with multiple colours, honed to reveal stain gradation, complex shape, premium sealer or wax protection. Common for architectural feature slabs and boutique commercial fitouts. |
What drives the cost in Perth
Colouring method
Integral oxide (mixed through the concrete) is most durable — the colour runs through the full slab depth, so wear and chips don't reveal a different colour underneath. Costs more upfront ($8–$18 per m² over plain grey) but never fades to grey. Dry-shake hardener (colour + hardening compound broadcast on wet concrete) sits in the top 3–5mm and is more vibrant but slowly wears. Chemical acid stain reacts with cement to produce variegated colour — beautiful, permanent, and unpredictable. Surface coating (paint, epoxy) is cheapest and shortest-lived.
Oxide colour choice
Standard oxide colours (charcoal, red, buff, ochre) are stocked at ready-mix plants and add $8–$12 per m². Custom colour matching adds $12–$18 per m² and may need to be pre-batched. Very dark colours require oxide loadings that can affect concrete strength — insist on a specific oxide dose per m³ from the supplier.
Colour consistency
Coloured concrete shows more variation than plain grey — batch-to-batch differences in oxide dose, water content, and cure conditions all read visibly. Best practice is to order the full pour from one plant on one day, and to specify a curing method that keeps moisture consistent (hessian + plastic, not just plastic).
Sealer's effect on colour
Solvent-based sealers deepen and saturate coloured concrete beautifully — highly recommended for oxide and stained finishes. Water-based sealers barely change appearance. The 'wet look' most homeowners prefer for coloured driveways comes from the sealer, not the concrete itself.
Repair implications
Integral coloured concrete is nearly impossible to patch-match perfectly if damaged — any repair will show. Surface-coloured concrete (stain, dry-shake) can be re-stained on top of a repair. Consider maintenance access and future repair likelihood when choosing colouring method.
Process
- 1
Colour spec confirmation
Confirm exact oxide type, colour name and dose (usually kg per m³) with the ready-mix supplier before pour day. Get a small poured sample from the same batch if custom colour — actual poured colour differs from chip samples on paper.
- 2
Base and formwork
Same as any driveway or slab — 100mm compacted base, formwork with fall, SL72 mesh minimum on chairs.
- 3
Consistent pour
Pour the full slab from a single truck or in immediately sequential trucks from the same plant. Any delay between trucks risks colour variation between sections. For dry-shake: broadcast the hardener + colour compound onto the bull-floated surface at the specified rate, then trowel in.
- 4
Careful finishing
Over-trowelling coloured concrete brings finer fines to the surface and produces a lighter, patchy finish. Bull-float, wait for bleed water, edge and saw-cut, then trowel gently to the required smoothness — not more.
- 5
Consistent cure
Damp-cure for 7 days with hessian and plastic. Colour reads darker while damp and lightens as it dries — final colour is only visible after 14–21 days. Do not judge the colour on the day of the pour.
- 6
Seal for colour enhancement
Apply a solvent-based UV-stable sealer at 21–28 days. First coat penetrates and saturates the colour. Second coat perpendicular within 24 hours. Reseal every 3–5 years to maintain colour depth.
Perth-specific considerations
- Perth's high UV load fades some cheaper iron-oxide colours (particularly reds) noticeably in the first 12 months. Insist on synthetic-oxide colours from a reputable supplier — they hold colour far better under WA sun.
- The pale limestone-clad house style common in Perth's western suburbs pairs well with warm buff, sandstone and honey oxide colours. Dark charcoal and near-black look sharper against modern architectural houses.
- Coastal salt in Cottesloe, Fremantle, Alkimos and Golden Bay can leach efflorescence through coloured concrete more visibly than plain grey. Sealing is essential, not optional.
- West-facing coloured driveways in dark charcoal reach 65°C+ on summer afternoons. Consider mid-tone colours for anything the family walks on barefoot.
- For the reactive Guildford clay in Ellenbrook and Aveley, colour variation caused by slab movement and micro-cracking can be more visible on lighter colours. Darker mid-tones hide movement micro-cracking better.
Compare with the alternatives
Exposed aggregate as a coloured alternative
Exposed aggregate delivers colour through the aggregate itself — different pebble blends produce very different visual results without the fading risk of oxide-coloured concrete. Often the smarter choice for outdoor slabs in Perth's UV environment.

Plain grey remains the cheapest and most robust driveway option. If colour isn't essential to the design, plain grey with a good sealer looks smart and lasts indefinitely — read the driveway page for full pricing.

Frequently asked questions
How much does coloured concrete cost in Perth?
Between $100 and $170 per square metre installed depending on method. A 40m² coloured driveway in integral oxide runs $4,000–$5,800. The same driveway in premium chemical stain with honed finish runs $5,800–$6,800. Surface paint coatings are cheaper ($20–$40 per m²) but not comparable in longevity.
Does coloured concrete fade in Perth?
Cheap iron-oxide colours can fade noticeably within 12–24 months under Perth UV. Synthetic-oxide colours from reputable suppliers (Bayferrox, Habitat, and equivalents) hold colour for 15+ years with proper sealing. The sealer maintenance schedule matters as much as the initial colour choice — a resealed slab stays vibrant, a neglected one greys.
What's the difference between integral and surface coloured concrete?
Integral colour is mixed through the concrete before the pour — colour runs the full slab depth and won't wear off. Surface colour (dry-shake hardener, chemical stain, paint) sits in the top few millimetres and gradually wears with foot and vehicle traffic. Integral is more expensive upfront and more durable long-term. Surface treatments cost less but need renewal every 5–10 years.
Can I colour-match an existing concrete slab?
Close, but not perfectly. New concrete cures to a different final colour than aged concrete, and any patch or extension will read as slightly different at least in the first year. Stained or coloured overlays that go over both the existing and the new pour give the most consistent visual result.
What colours work best for a Perth driveway?
Mid-tone warm colours (honey, sandstone, buff, soft charcoal) suit Perth's dominant house styles and hide dust and minor staining. Dark charcoal is popular for modern architectural homes but heats up on west-facing driveways. Bright red and terracotta look great when new but are the colours most prone to UV fade — choose synthetic oxides if you go this route.
