Selecting a concrete finish might seem straightforward, but the decision has lasting consequences for the appearance, durability and maintenance of your surface. Whether you are building a new driveway, renovating a commercial floor or designing an alfresco entertaining area, the finish you choose will define how the space looks and functions for decades. In this guide we break down the most popular options so you can make an informed choice before the first truck arrives on site.
Exposed Aggregate
Exposed aggregate is one of the most popular decorative finishes in South Australia, and for good reason. The process involves pouring standard concrete, then washing or brushing the top layer of cement paste away before it fully cures. This reveals the natural stone, pebble or shell aggregate embedded in the mix, creating a textured surface with inherent grip.
The look depends entirely on the aggregate blend. Local suppliers like Clustries offer a wide palette of colours derived from Southern Fleurieu and Yorke Peninsula stone. Warm golds, cool greys, rich reds and soft creams are all achievable depending on the aggregate selected. Exposed aggregate is best suited for outdoor areas where slip resistance matters — driveways, pool surrounds, footpaths and courtyards are the most common applications.
Maintenance is straightforward. A pressure wash once or twice a year and a resealing every three to five years will keep the surface looking fresh. Because the texture is inherent to the material rather than applied on top, it does not wear away under foot or vehicle traffic. For a deeper look at upkeep, check out our seasonal maintenance guide.
Polished Concrete
Polished concrete takes the opposite approach to exposed aggregate. Rather than revealing texture, it refines the surface through progressive grinding and polishing until it achieves a smooth, reflective finish. The level of aggregate exposure is controlled during grinding — you can opt for a subtle salt-and-pepper look, a full stone reveal or a cream finish with minimal aggregate visibility.
The result is a floor that feels contemporary, clean and sophisticated. Polished concrete is a favourite for open-plan living areas, retail spaces, restaurants and office fit-outs. It reflects ambient light, making rooms feel larger and brighter. It is also highly practical — the sealed surface resists moisture, stains and dust accumulation, which is why commercial kitchens and showrooms often choose it.
One additional benefit is thermal mass. Concrete absorbs heat during the day and releases it slowly at night, helping to regulate indoor temperatures without relying entirely on mechanical heating or cooling. If energy efficiency matters to your project, polished concrete is worth serious consideration. Explore our polished concrete range for colour options.
Stamped and Decorative Finishes
Stamped concrete allows you to replicate the appearance of brick, stone, slate or cobblestone at a fraction of the cost of natural materials. The process involves pressing large rubber mats or stamps into freshly poured concrete, then applying colour hardeners and release agents to build depth and realism.
The versatility of stamped finishes makes them popular for patios, driveways, commercial forecourts and public spaces. You can combine multiple stamp patterns and colours within a single pour to create borders, inlays or feature zones. Integral oxide colours ensure the tone goes right through the slab rather than sitting on the surface, so it will not chip or flake.
Stamped concrete does require periodic resealing to maintain its colour intensity and protect against UV exposure. In high-traffic areas, a high-quality sealer with anti-slip additive is recommended. For details on our decorative product range, visit the decorative finishes page.
Broomed and Brushed Finishes
Sometimes the simplest option is the best one. Broomed concrete is created by dragging a stiff-bristled broom across the surface of freshly floated concrete. The resulting linear grooves provide excellent traction, making it the standard choice for public footpaths, crossovers and commercial hardstands where safety compliance is paramount.
Broomed finishes can be combined with integral colour to add visual interest without the cost of exposed or polished treatments. A coloured broomed driveway crossover paired with an exposed aggregate main driveway, for example, creates a clean delineation between public and private space.
Making Your Decision
The right finish depends on three factors: location, budget and aesthetic preference. For outdoor surfaces that will see rain, foot traffic or vehicles, exposed aggregate and broomed finishes provide the best grip. For indoor floors where visual impact and low maintenance matter most, polished concrete leads the field. Stamped and decorative options sit in between, offering design flexibility at a moderate cost.
If you are still unsure, the best next step is to see samples in person. Visit our Thebarton showroom or call our team on (08) 8334 4777 to arrange a site consultation. We can match finishes to your project brief and provide sample panels so you can see exactly what you are getting before committing.
