Spray on concrete vs stencil concrete is one of the most common finish questions homeowners ask when resurfacing a Central Coast driveway. The short version: spray-on gives you a broader colour range and a cleaner look for modern homes, while stencil applies a pattern meant to resemble tiles or pavers, which works well on some properties but reads as a dated style on others. Our concrete finishes guide covers the full range of options. This guide focuses specifically on what separates these two systems and which conditions suit each.
The short answer: what each finish actually is
Spray-on concrete, also called spray-on paving or spraycrete, is a polymer-modified cementitious overlay applied through a hopper gun. The texture comes from the gun pattern and the aggregate size in the mix. Colour is added as an integral pigment in the mix or as a separate coloured sealer coat. The finish is consistent across the surface and can be adjusted from coarse to relatively fine depending on the product.
Stencil concrete uses the same base overlay material but lays a wax paper or plastic stencil pattern on the slab before spraying. The contractor sprays the overlay, pulls the stencil while the material is still workable, and the recessed lines left behind become the simulated joint pattern. A contrasting colour in the groove creates the appearance of tiles, brick or cobblestone.
Both systems go over an existing concrete slab. Neither is a full concrete replacement. You can find more detail on our spray-on concrete service page.
How they look up close (and from the street)
Spray-on, viewed close-up, shows a uniform stippled or lace texture. It reads as a solid colour field from the street, often with a slight sheen from the sealer. It suits rendered homes, Colorbond-roofed homes and any property with a contemporary or clean-line aesthetic.
Stencil, close-up, shows the pattern clearly. The grooves between sections can be a different colour or simply a recessed shadow. From the street, a stencil driveway reads as a patterned surface, somewhere between tile and paving in appearance.
Stencil concrete peaked in popularity during the 1990s and early 2000s. It still suits some property styles, particularly older brick homes where a paver-like pattern fits the character of the building. On a contemporary or rendered home, it can look out of step with the architecture. Be honest with yourself about which category your home falls into before committing to a stencil finish.
Longevity and how each ages on the Coast
Both systems age similarly at their base: the overlay itself is the same material. The difference is in how the pattern holds up over time. On a spray-on finish, UV exposure fades the colour relatively evenly, and a reseal restores the appearance. On a stencil, the groove lines collect dirt, biological growth and salt film. The contrast between the field and the joint can become uneven in ways that are difficult to reverse without a full regrind.
On the Central Coast, salt air and UV act together on both systems. Regular resealing every two to three years, closer to two years for properties near the water, extends the life of either finish. Our driveway resurfacing service covers the full maintenance picture.
Typical expected lifespan with good maintenance:
- Spray-on: 12-18 years before the overlay needs attention
- Stencil: 10-15 years, with groove-cleaning becoming more necessary from year five onward
Slip resistance, especially around pools
Spray-on texture is naturally non-slip because the stippled surface profile holds grip even when wet. The degree of texture can be adjusted by the contractor: a coarser gun pattern gives more grip; a finer one is smoother underfoot.
Stencil creates a more variable surface. The flat sections between joints are smoother than the corresponding area on a spray-on finish. The recessed grooves do not contribute to overall grip. Around pools or on steep driveways, a stencil surface with a gloss sealer can be significantly more slippery than an equivalent spray-on finish.
For pool surrounds and steep grades, spray-on is the safer default. If slip resistance is a priority, mention it to your contractor and confirm what grip rating the proposed finish achieves. See also our comparison of spray-on concrete vs exposed aggregate for another common alternative.
Repairability if a section is damaged later
Spray-on is generally easier to spot-repair. If one section is damaged, a skilled contractor can blend a repair patch into the surrounding texture with reasonable colour consistency. The repair is not invisible, but it is acceptable on most domestic driveways.
Stencil is harder to repair convincingly. The pattern alignment needs to match precisely, and the colour in the groove must be consistent. A poorly matched stencil repair can look worse than the original damage. For this reason, if your driveway sees heavy vehicle use, overhanging trees that drop debris or other damage risks, a spray-on finish is more forgiving over the long run.
Indicative cost per square metre for each
Both finishes draw from the same base material and application process, so the cost difference is relatively modest for the overlay itself. Stencil takes more labour for pattern layout and pulling, so it is generally priced slightly higher.
| Finish | Indicative rate/m2 | Notes |
|---|---|---|
| Spray-on (single colour) | $60-$90 | Includes grind, overlay, sealer |
| Spray-on (two-colour or highlight) | $75-$105 | Second colour adds a sealer step |
| Stencil (single pattern, two colours) | $80-$120 | Extra labour for stencil layout and joint colouring |
| Stencil (complex pattern) | $95-$130 | More cuts, more colour stages |
These rates are indicative only. For specific pricing see the comparison in our acid stain vs concrete paint guide, which discusses finish and colour options in a different context.
Which finish suits which Central Coast home
As a practical guide:
- Rendered, contemporary or Colorbond-roofed home: spray-on in a neutral grey, warm sandstone or off-white almost always suits
- Older brick home or cottage character: stencil in a pattern that echoes the brickwork can complement the style, but check that the pattern scale works with the driveway width
- Pool surround or alfresco: spray-on with a non-slip texture; avoid stencil around water
- Steep driveway: spray-on with a grip additive; stencil and steep grades are a poor combination
If you are unsure, ask the contractor to show you examples of both finishes installed on comparable properties before you decide. Most experienced contractors will have photos.

FAQs
Can a stencil driveway be converted to spray-on later?
Yes, with a regrind. If a stencil finish has aged to the point where it looks tired, the slab can be diamond-ground back to a clean profile and a spray-on system applied over it. The groove lines from the stencil will disappear under the new overlay provided the grind is sufficient.
Is stencil concrete still popular on the Central Coast?
It remains in use, particularly for homeowners who want a pattern-effect driveway on an older-style property. It is less dominant than it was in the early 2000s. More homeowners now choose a solid spray-on with a custom colour rather than a simulated paver pattern.
Do both finishes need the same maintenance?
Broadly yes, both need resealing every two to three years depending on sun exposure and proximity to salt water. Stencil surfaces may also benefit from periodic cleaning of the groove lines with a soft brush and mild cleaner to prevent biological build-up in the recesses.
Can spray-on concrete be applied over stencil concrete?
Yes, if the existing stencil overlay is sound and well-bonded. A diamond grind to remove the gloss from the old sealer and key the surface is necessary before the new overlay goes down. A contractor will check for any delaminating sections before quoting.
What happens if the stencil pattern does not align on my driveway?
On a curved driveway or an irregular shape, stencil alignment requires more planning. An experienced contractor will dry-lay the stencil pattern before committing and discuss any alignment compromises with you. Tight curves and awkward corners are genuinely more difficult with stencil than with plain spray-on.
