At Superfloor Australia, we’re excited to share our expertise on creating stunning polished concrete floors with exposed aggregate. This innovative flooring technique combines the durability of polished concrete with the unique aesthetic of exposed aggregate.
Polished concrete floors with exposed aggregate offer a perfect blend of style and functionality, suitable for both residential and commercial spaces. In this guide, we’ll walk you through the process, design options, and maintenance tips to help you achieve the perfect exposed aggregate polished concrete floor.
What is Exposed Aggregate Polished Concrete?
The Unique Characteristics of Exposed Aggregate
Exposed aggregate polished concrete floors showcase a variety of stones, pebbles, or even glass embedded in the concrete surface. This technique creates a textured, visually interesting floor that combines functionality with aesthetic appeal. The exposed materials can range from small pebbles to larger stones, offering a wide array of design possibilities.
Benefits of Exposed Aggregate Polished Concrete
This flooring type offers numerous advantages. Its incredible durability stands out as a primary benefit. The polished concrete base provides a strong foundation, while the exposed aggregate adds an extra layer of wear resistance. This makes it ideal for high-traffic areas in both residential and commercial spaces.
Low maintenance is another key advantage. Unlike carpet or hardwood, exposed aggregate polished concrete doesn’t require frequent cleaning or refinishing. A simple sweep and occasional mop usually suffice to maintain its appearance.
Environmental friendliness also sets this flooring apart. Concrete is a sustainable material, and the use of local aggregates further reduces environmental impact. Plus, the reflective surface of polished concrete can help reduce lighting costs, which uses approximately 5% of average Australian home energy consumption and 30-50% in commercial buildings.
Popular Applications
Exposed aggregate polished concrete finds applications in various settings. In homes, it’s a popular choice for entryways, living rooms, and outdoor patios. The slip-resistant nature of the textured surface makes it a safe option for areas that may get wet.
Commercial spaces often feature this flooring type in retail stores, restaurants, and office buildings. The floor’s durability withstands heavy foot traffic, while its unique appearance creates a memorable impression on customers and clients.
Industrial facilities also benefit from this flooring type. The strength of polished concrete combined with the added texture of exposed aggregate creates a surface that can withstand heavy machinery and frequent cleaning.
Choosing the Right Contractor
While many companies offer concrete flooring solutions, it’s important to choose a contractor with expertise in exposed aggregate polished concrete. Look for a team that understands the intricacies of achieving the perfect balance between polished concrete and exposed aggregate. This ensures a floor that not only looks stunning but also performs exceptionally well over time.
Superfloor Australia stands out as a top choice in Brisbane, known for their precision and attention to detail in delivering high-quality polished concrete flooring solutions.
As we move forward, let’s explore the process of creating these stunning floors, from surface preparation to the final polishing stages.
How to Create Exposed Aggregate Polished Concrete
Creating exposed aggregate concrete flooring requires skill, precision, and the right equipment. This process transforms ordinary concrete into a stunning, durable surface that combines functionality with aesthetic appeal.
Surface Preparation
The journey starts with thorough surface preparation. Clean the concrete slab to remove dirt, dust, and debris. This step ensures proper adhesion and a flawless finish. For existing concrete, use specialised equipment to grind down high spots or fill low areas, creating a level surface.
Application of Surface Retarder
Apply a surface retarder next. This chemical slows down the setting of the concrete’s surface layer, allowing for aggregate exposure later. Spray the retarder carefully onto the freshly poured concrete, ensuring even coverage.
Exposing the Aggregate
After the concrete partially sets (typically within 24 hours), expose the aggregate. This process involves washing away the top layer of cement paste using pressurised water. The timing is critical – start too early, and the aggregate may come loose; start too late, and removing the surface layer becomes difficult.
The depth of exposure varies depending on the desired look. Light exposure reveals just the tips of the aggregate, while a deeper wash exposes more of the stones. This step demands a keen eye and experience to achieve the perfect balance.
Grinding and Polishing
Once the aggregate is exposed and the concrete fully cures, move on to grinding and polishing. This process typically involves multiple passes with progressively finer diamond abrasives.
Start with coarse diamond tools to level the surface and remove minor imperfections. As you progress to finer grits, the floor develops its signature shine. The number of grinding steps varies depending on the desired polish level.
Sealing for Protection
The final step involves sealing the floor. A high-quality sealer enhances the appearance and provides protection against stains and wear.
Use a penetrating sealer that bonds with the concrete at a molecular level. This type of sealer doesn’t form a film on the surface, allowing the natural beauty of the exposed aggregate to shine through while still offering excellent protection.
The entire process, from initial preparation to final sealing, can take several days to complete. The result is a floor that combines the durability of polished concrete with the unique aesthetic appeal of exposed aggregate – a surface that’s not only beautiful but also built to last.
Now that we’ve covered the creation process, let’s explore the various design options and customisation possibilities that make exposed aggregate polished concrete a versatile flooring choice.
Customising Your Exposed Aggregate Polished Concrete
Aggregate Selection
The choice of aggregate significantly impacts the final look of your floor. River rocks create a natural, organic feel, while crushed granite adds elegance. For a modern twist, consider recycled glass or seashells. The size of your aggregate matters too. Smaller stones (1/4 inch or less) create a more uniform look, while larger pieces (up to 3/4 inch) make bold statements.
In Brisbane, local Queensland aggregates have gained popularity. These support local businesses and give floors a distinct regional character. A mix of Mount Isa granite and Brisbane River pebbles, for example, creates a stunning representation of Queensland’s diverse landscape.
Colour Considerations
The concrete matrix colour sets the tone for your entire floor. While natural grey concrete remains popular, colour options abound. Integral colour admixtures can transform your concrete into rich earth tones, cool blues, or warm terracottas.
A deep charcoal matrix combined with white quartz aggregate creates a striking contrast, resulting in a modern, sophisticated look that becomes the focal point of any space.
Pattern Play
Patterns add another layer of customisation to exposed aggregate polished concrete. Saw-cut designs, created after the concrete cures, can range from simple geometric shapes to complex mandalas. These cuts can be filled with contrasting aggregate or left unfilled for a more subtle effect.
A flowing river pattern using blue glass aggregate set against a light grey concrete guides foot traffic through a space while adding a unique visual element.
Combining Techniques
Exposed aggregate polished concrete works well with other decorative concrete techniques for truly unique results. Stencilling adds intricate designs to specific areas. Acid staining creates variegated colour effects that complement the exposed aggregate.
An innovative approach combines exposed aggregate with glow-in-the-dark aggregates in outdoor spaces. Glow stones are applied in exposed aggregate finishes in the same way as other decorative aggregates such as seashells and tumbled recycled glass.
Balancing Elements
The key to a successful exposed aggregate polished concrete floor lies in balancing these elements. Too many competing elements can create visual chaos, while too few might result in a bland surface. Try to strike the perfect balance, creating floors that are both visually stunning and functionally superior.
