If you’re planning a concrete resurfacing job in Port Stephens, one of the first decisions is the finish type. The options — spray-on texture, stencil, exposed aggregate, epoxy — have different appearances, different coastal performance characteristics, and different price points. This guide helps you understand the differences before you commit.
Spray-On Texture Coating
What it looks like: A uniform, natural-aggregate texture — similar to a fine sandpaper or brushed concrete in appearance, but smoother and more consistent. Available in a wide range of colours. The most common finish on Port Stephens driveways, pool surrounds and patios.
How it works: A polymer-modified cementitious overlay is spray-applied to the existing concrete surface. Fine aggregate in the mix creates the texture. A UV-stable sealer topcoat provides colour, protection and ongoing waterproofing.
Coastal performance: Excellent, when quality products are used. Dulux Avista and equivalent systems are specifically engineered for Australian coastal conditions. UV stabilisers in the sealer resist bleaching; the cementitious overlay is inherently salt-resistant; thickness of 3–6mm provides a meaningful wearing layer.
Suitable for: Driveways, pool surrounds, patios, alfresco areas, paths. The most versatile finish.
Cost range: $80–$130/m² (including preparation and sealing)
Pros:
- Most cost-effective resurfacing option
- Excellent coastal UV and salt performance with quality products
- Natural, neutral appearance suits most properties
- Non-slip texture inherent in the aggregate mix
- Applicable to most concrete substrates
Cons:
- Appearance is uniform and textured — not decorative
- Limited visual interest compared to stencil
Stencil Concrete
What it looks like: A spray-on overlay with a pattern pressed into it before cure — creating the appearance of pavers, stone, slate or brick. The pattern is defined by the stencil; the colour can be a base coat with antique wash for depth, or a single uniform colour.
How it works: After surface preparation and priming, a stencil pattern (typically a flexible mesh) is laid over the surface. The overlay is spray-applied over the stencil. When the overlay reaches the right cure stage, the stencil is removed, leaving the pattern. A colour sealer or antique wash is applied to finish.
Coastal performance: Good to very good, depending on sealer quality. The stencil overlay is the same cementitious system as plain spray-on — the pattern doesn’t affect durability. Sealer quality matters for colour retention. High-UV coastal environments will fade lower-grade sealers more quickly in decorative colours — we use UV-stable formulations for stencil work in Port Stephens.
Suitable for: Driveways (very popular), patios, entrance areas, pool surrounds (with appropriate non-slip sealer). Particularly popular for holiday homes and Airbnb properties where visual impact matters for listing photos.
Cost range: $120–$180/m² (including preparation, stencil, antique wash and sealing)
Pros:
- Dramatic visual transformation — can look like slate, stone, or cobblestone
- Significantly upgrades kerb appeal and property photography
- Excellent value compared to actual paver replacement
- Available in many pattern and colour combinations
Cons:
- More expensive than plain spray-on
- Colour fade over time is more visible in decorative finishes than in plain colours
- Requires more planning and skilled application for pattern alignment

Exposed Aggregate
What it looks like: A concrete surface where the coarse aggregate — often a mix of coloured stones, pebbles or quartz — is visible at the surface. Has a natural, stone-like appearance with significant texture variation.
How it works (new or resurfaced): For new concrete, aggregate is seeded onto the wet pour and the surface cream is washed away before it cures. For resurfacing of existing concrete, an exposed aggregate overlay can be applied that contains the decorative aggregate in the mix.
Coastal performance: Moderate. Natural stone aggregates themselves are UV-stable and won’t bleach. The sealer protecting exposed aggregate needs to be UV-stable. The textured, open surface of exposed aggregate can collect salt deposits in coastal environments — regular cleaning is important.
Suitable for: Driveways (very common in Port Stephens), garden paths, pool surrounds (aggregate provides inherent non-slip texture). Many Port Stephens homes from the 1990s were built with exposed aggregate driveways — resurfacing often involves either overlaying the exposed aggregate or refreshing its sealer.
Cost range: Resealing existing exposed aggregate: $1,500–$3,000. New exposed aggregate overlay: $90–$140/m²
Pros:
- Natural, varied appearance
- Inherent non-slip texture from aggregate
- Established look suits many Port Stephens properties
Cons:
- Open surface can collect salt — requires regular cleaning
- Sealer maintenance is important to keep aggregate from further loosening
- Can be rough underfoot if aggregate is coarse — not ideal for bare feet around pools
Epoxy and Polyaspartic Coatings
What it looks like: A smooth, high-gloss or semi-gloss floor coating. Can be plain solid colour, decorative vinyl flake (a popular speckled finish), or high-end metallic effects.
How it works: A 2-component coating system that chemically crosslinks after application to form an extremely hard, chemical-resistant surface. Applied in thin layers (1–3mm total).
Coastal performance: Polyaspartic is recommended for coastal locations due to its UV stability — it won’t yellow like standard epoxy can under coastal UV. For internal garages with minimal UV exposure, standard epoxy is acceptable.
Suitable for: Garage floors primarily. Not suitable for outdoor surfaces subject to direct UV — epoxy yellows outdoors. Polyaspartic variants designed for outdoor use exist but the spray-on overlay system is generally more appropriate for most outdoor Port Stephens applications.
Cost range: $60–$120/m² for residential garage applications
Pros:
- Extremely hardwearing for vehicle traffic
- Easy to clean — smooth surface doesn’t trap dirt
- Professional, clean appearance
- Polyaspartic installs in a single day
Cons:
- Standard epoxy yellows under UV — not suitable for outdoor use
- More expensive per m² than basic spray-on for outdoor applications
- Requires very thorough surface preparation

Which Finish Is Right for Your Port Stephens Property?
For most driveways: Spray-on texture overlay in an appropriate colour. Best coastal performance, best value, looks right on most Port Stephens properties.
For holiday homes and pre-sale preparation: Stencil concrete where maximum visual impact and listing photo appeal is the priority. The extra cost pays back in perception.
For existing exposed aggregate driveways: Depends on condition. If the aggregate is sound and just the sealer is aged, a reseal is appropriate. If the aggregate is loose or the surface has deteriorated, an overlay over the existing surface is a practical alternative.
For garages: Polyaspartic for Port Stephens’s coastal environment — UV-stable, single-day installation, hardwearing.
For pool surrounds: Spray-on texture with non-slip aggregate and chlorine-resistant sealer. Not stencil (not appropriate for the wet barefoot environment), not epoxy.
Frequently Asked Questions
Can I change from exposed aggregate to a plain spray-on finish? Yes. An exposed aggregate surface can be overlaid with a spray-on texture coat. This covers the aggregate (it won’t be visible), fills between the aggregate stones, and creates a smooth texture surface. The result is a plain spray-on finish over the existing aggregate base.
Is stencil concrete slippery when wet? Standard stencil sealers have some non-slip character but less than purpose-applied aggregate finishes. For pool surrounds and outdoor entertaining areas adjacent to water, we add anti-slip aggregate to the sealer topcoat on stencil finishes. For driveways, standard stencil sealer is generally adequate.
Which finish lasts longest in Port Stephens’s coastal environment? All quality finishes last 10–15 years with proper preparation and coastal-rated products. The difference is in maintenance: decorative stencil colours may need resealing at 7–8 years to maintain their fresh appearance even if they’re structurally sound. Plain spray-on textures are more forgiving of minor sealer fade.
