At Superfloor Australia, we’re passionate about creating stunning concrete floors that elevate any space. Burnished concrete floors offer a unique blend of durability and aesthetic appeal, making them an increasingly popular choice for both residential and commercial properties.
In this guide, we’ll explore the process of achieving beautiful burnished concrete floors, from understanding the basics to mastering maintenance techniques. Whether you’re a homeowner or a contractor, you’ll find valuable insights to help you make informed decisions about this versatile flooring option.
What Is Burnished Concrete?
The Burnishing Process
Burnished concrete transforms ordinary concrete into a smooth, glossy surface without extensive grinding. The process uses a power trowel, also known as a burnisher, to heat, melt, and buff a wax-based coating into the concrete surface. This results in a dense, smooth finish that’s both attractive and durable.
Burnished vs. Polished Concrete
Burnished and polished concrete create glossy finishes, but they differ significantly in process and outcome. Polished concrete requires multiple grinding steps with progressively finer abrasives, often exposing aggregate. Burnishing preserves the existing surface, making it a quicker and more cost-effective option.
Polished concrete typically achieves a higher shine and allows for more customisation, but it’s also more labour-intensive and expensive. Burnished concrete provides a satin-like finish that’s perfect for those seeking a more subtle sheen.
Benefits of Burnished Concrete Floors
Burnished concrete floors offer numerous advantages:
- Durability: These floors withstand heavy foot traffic and equipment without damage, making them ideal for both residential and commercial spaces.
- Low Maintenance: Regular sweeping and occasional damp mopping keep the floor looking great. This translates to significant cost savings over time.
- Energy Efficiency: The reflective surface of burnished concrete improves ambient lighting, potentially reducing energy costs. Some studies suggest that using this type of concrete can save up to 14% of energy consumption compared to conventional windows.
- Sustainability: Burnished concrete utilises the existing concrete slab, reducing the need for additional materials. Its longevity means less frequent replacement, further minimising environmental impact.
- Cost-Effectiveness: While costs vary, you can expect to pay between $2 to $6 per square foot (depending on factors like location and project complexity). Considering its durability and low maintenance requirements, burnished concrete proves to be a cost-effective flooring solution in the long run.
Aesthetic Appeal
Burnished concrete offers a unique aesthetic that combines industrial chic with modern elegance. The satin-like finish (which can range from matte to high-gloss) complements various design styles, from minimalist to rustic. This versatility allows it to seamlessly integrate into diverse architectural contexts, enhancing the overall visual appeal of any space.
The next chapter will explore the step-by-step process of creating beautiful burnished concrete floors, starting with proper surface preparation.
How to Create Burnished Concrete Floors
Surface Preparation
The foundation of beautiful burnished concrete floors lies in meticulous surface preparation. We start by thoroughly cleaning the concrete to remove all dirt, dust, and debris. This step ensures a uniform finish and proper adhesion of sealers and densifiers.
After cleaning, we inspect the surface for cracks, holes, or imperfections. We fill and level these areas to create a smooth canvas for burnishing. In some cases, we grind down high spots or use a self-levelling compound to address unevenness.
The Burnishing Process
Once the surface is prepped, we begin the burnishing process. This involves multiple passes with a high-speed burnishing machine (with adjustable speeds between 300-2000 RPM). We use diamond-impregnated buffing pads, starting with coarser grits and progressively moving to finer ones.
The first pass smooths out any remaining imperfections and opens up the pores of the concrete. Subsequent passes continue to refine the surface, gradually increasing the shine. The heat generated by the burnisher melts and buffs the wax-based coating into the concrete, creating that characteristic satin-like finish.
Application of Densifiers and Sealers
To enhance durability and shine, we apply a concrete densifier during the burnishing process. This liquid penetrates the concrete, chemically reacting with it to increase its density and hardness. The result is a more durable surface that resists abrasion and staining.
After the densifier cures, we apply a high-quality concrete sealer. This step protects the burnished finish from stains and damage. The sealer also enhances the floor’s appearance, bringing out the rich colour and depth of the concrete.
Achieving the Desired Sheen
The final step in our process involves buffing the floor to achieve the desired level of sheen. This can range from a subtle matte finish to a high-gloss shine (depending on the client’s preferences). We use ultra-fine buffing pads for this step, carefully working the surface to create a uniform, lustrous appearance.
It’s worth noting that while burnished concrete can achieve a beautiful shine, it won’t reach the same level of gloss as fully polished concrete. However, many clients prefer the more subtle, satin-like finish of burnished concrete for its understated elegance.
Creating beautiful burnished concrete floors requires experience, skill, and attention to detail at every step of the process. While DIY enthusiasts might want to tackle this project themselves, we strongly recommend hiring professionals for the best results. The investment in professional installation (such as Superfloor Australia) pays off in the long run, ensuring a durable, beautiful floor that will last for years.
Now that we’ve covered the creation process, let’s explore how to maintain and care for your burnished concrete floors to keep them looking their best for years to come.
How to Keep Your Burnished Concrete Floor Looking Great
Daily Cleaning Routine
To maintain burnished concrete floors, use a dust mop or soft-bristled broom daily to remove loose dirt and debris. This prevents scratches from abrasive particles. For thorough cleaning, use a damp mop with a pH-neutral cleaner designed for concrete floors. Avoid harsh chemicals or acidic cleaners, as these can damage the sealer and dull the finish.
Dealing with Spills and Stains
Act quickly when spills occur. Blot liquids immediately with a clean, dry cloth. For stubborn stains, use a mild soap solution and gently scrub with a soft brush. Rinse thoroughly and dry the area to prevent water spots.
For oil-based stains, apply a poultice made from baking soda and water. Leave it on overnight, then scrub gently and rinse. This method can lift stubborn stains without damaging the floor’s finish.
Periodic Maintenance
Under normal conditions, resealing may be required every 18-24 months to maintain the floor’s protective barrier. This resealing process helps prevent staining and extends the life of your burnished concrete floor.
Before resealing, clean the floor thoroughly and allow it to dry completely. Apply the sealer evenly using a microfibre mop or a low-pressure sprayer. Allow each coat to dry before applying the next, and follow the manufacturer’s instructions for drying times and number of coats.
Professional Maintenance
While property owners can handle regular care, professional maintenance every few years can significantly extend the life of your burnished concrete floor. Professional services often include deep cleaning, resealing, and rebuffing to restore the floor’s original lustre.
Many flooring companies offer comprehensive maintenance services for burnished concrete floors. These teams use specialised equipment and products to rejuvenate your floor, ensuring it continues to impress for years to come. The durability of burnished concrete lessens the need for replacement, contributing to long term sustainability. If you’re considering professional maintenance, Superfloor Australia stands out as a top choice among flooring specialists.
