Spray-On Concrete Finishes
Plenty of Central Coast homes already have spray-on paving — it was hugely popular through the 90s and 2000s, which is exactly why so much of it now looks chalky, faded and patchy after twenty-plus years of coastal sun. Whether you want to restore a tired stencilled surface or transform plain grey concrete into something with real colour and pattern, spray-on is the most versatile decorative system going.
Central Coast Concrete Revival arranges spray-on work through appropriately licensed local applicators who understand what our salt air and UV do to decorative coatings — and how to specify systems that cope with it.

What spray-on concrete is (and isn’t)
Spray-on concrete — also called spray paving or spray-crete — is a cement-based polymer coating applied through a hopper gun over existing concrete. It goes on a few millimetres thick and cures into a hard-wearing decorative skin. It is not paint, and it is not a new slab; it is a bonded cementitious layer that becomes part of the surface.
A typical system builds up in layers:
- Base coat in your background colour, spray-applied and trowelled where required.
- Stencil or tape pattern if you want the look of pavers, tiles, cobblestones or grouted stone — the stencil masks “grout lines” that reveal the base colour underneath.
- Colour coats sprayed over the stencil in one or more top colours, often flicked or mottled for a natural stone effect.
- Clear sealing, usually two coats, using sealers rated for coastal UV and salt exposure.
The sprayed texture itself has natural grip, and additives can lift that further — slip-resistant finishes are achievable, which matters on Coast paths and steps that spend half the winter damp.
Where spray-on works best
- Driveways wanting a paved or stone look without the cost of actual paving.
- Paths, porches and patios on 70s–90s brick homes where plain grey concrete drags the whole facade down.
- Faded stencilled surfaces — if you already have old spray paving, a re-spray restores pattern and colour, usually keeping the existing stencil lines.
- Pool surrounds and alfresco areas, where lighter colours also reflect heat better than dark paving.
- Step edges and porches where you want a defined, higher-grip nosing.
If your surface is more about damage than decoration — deep cracks, spalling, oil staining — start with our driveway resurfacing service, which deals with repair first and finish second. Not sure which system suits? Our concrete finishes guide compares spray-on, epoxy and overlays side by side.
Our process from enquiry to final seal
- Get in touch. Ring (02) 0000 0000 or send through the quote form with photos and rough measurements. If you have a Pinterest screenshot or a neighbour’s driveway you like, include that too — it shortcuts the colour conversation.
- On-site inspection and colour consult. A licensed local applicator checks the concrete is sound enough to coat, tests for old sealers or paint that would block adhesion, and brings colour charts and stencil pattern samples.
- Written quote covering prep, pattern, colours and sealing. Guide figures on this site are indicative only — the formal quote is the real number.
- Surface preparation. High-pressure cleaning, degreasing, crack filling and etching or grinding. On previously coated surfaces, failed material is stripped back — skipping this step is why cheap spray jobs peel, so ours don’t skip it.
- Masking and spraying. House walls, garage doors and gardens are masked off. Base coat, stencil, top coats. Applicators work around Coast weather windows — spraying ahead of a southerly buster or in heavy sea-mist humidity ruins finishes, so the schedule flexes with the forecast.
- Sealing, cure and handover. Two coats of UV-stable sealer, overspray cleaned up, masking removed, and clear guidance on cure times — typically walking on it in around a day, driving on it after several days, product depending.
What affects spray-on concrete pricing
- Area in square metres — the biggest single factor.
- Pattern complexity — plain or simply bordered finishes cost less than full stencil patterns; multiple colours and feature borders add labour.
- Condition of the existing slab — sound grey concrete needs modest prep; flaking old coatings need stripping.
- Site layout — steps, curves, tight side paths and multi-level areas take longer than one open rectangle.
Indicative price guide
Indicative guide ranges only, drawn from typical Australian spray-paving pricing — confirmed after inspection and formal quote.
| Project | Indicative range (guide only) |
|---|---|
| Porch, path or small patio | $1,200 – $2,800 |
| Single driveway, plain colour with border | $2,500 – $4,500 |
| Double driveway, full stencil pattern | $4,000 – $7,000+ |
| Re-spray/restore existing faded spray paving | $1,800 – $5,000 |
Our concrete resurfacing cost guide explains where in these ranges a job like yours is likely to land.
Included vs extra
Included as standard:
- Full surface prep — clean, degrease, etch/grind, standard crack fill
- Masking of adjacent surfaces and gardens
- Base coat, stencil pattern (if selected) and top colours as quoted
- Two coats of coastal-grade UV-stable sealer
- Clean-up and washout disposal handled off your garden beds
Potential extras, itemised up front:
- Stripping thick paint or badly failed previous coatings
- Repairs to drummy, delaminated or heavily spalled sections
- Custom stencils, logos or multi-zone colour designs
- Additional slip-resistant additive for steep gradients or pool zones
- Re-coating concrete that turns out to be too far gone (we will recommend resurfacing instead, not just spray over problems)
Related services and service area
Spray-on is one of three decorative paths we offer — see pool surround resurfacing for wet-area work and driveway resurfacing where repair is the priority. We arrange spray-on projects Coast-wide, including the beachside corridor around Terrigal and older coastal homes around The Entrance and Long Jetty.
Spray-on concrete FAQs
Can you spray over my old stencilled driveway?
Usually, yes. If the original coating is mostly sound, it is prepped and re-sprayed — often reusing the existing pattern lines. If it is lifting in sheets, it needs stripping first, which the inspection will pick up.
Does spray-on concrete get slippery when wet?
The sprayed texture is naturally grippier than smooth concrete, and slip-resistant finishes are achievable with additives. No outdoor surface is slip-proof, so we phrase it exactly that way — achievable grip, not a guarantee.
How does coastal weather affect the finish?
Salt air and UV fade and chalk unsealed or cheaply sealed coatings faster than inland. Coastal-grade sealers and a reseal every few years are the difference between a finish that lasts and one that looks tired by year three.
How hot does it get underfoot?
Lighter colours stay noticeably cooler than dark surfaces in summer — one reason cream, sand and pale grey palettes are popular for Coast pool areas and north-facing patios.
Is spray-on the same as concrete resurfacing?
Spray-on is one type of resurfacing. Trowelled overlays and epoxy systems are others. The finishes guide covers which suits which situation.
