What is burnished concrete?

Are you wondering what is burnished concrete? Burnished concrete is a sleek and glossy finish achieved by polishing the surface of concrete to create a smooth, reflective appearance. This process involves using a high-speed burnisher that rotates between 1,500 to 2,500 rpm. Specialised machines are used to apply heat, which melts and buffs a topical coating or wax-based product into the polished surface. To further enhance the concrete’s durability and hardness, a densifier product can also be applied.

Burnished concrete floors pros

A burnished concrete floor offers exceptional durability and can last for decades with minimal maintenance. As one of the most low-maintenance surface options available, burnished concrete is an excellent choice for both residential and commercial spaces.

Some of the key benefits of choosing burnished concrete floors include:

• Cost-Effective: Compared to mechanically polished concrete, the burnishing process requires less labor and fewer steps, reducing overall costs.

• Durability: Burnished concrete is highly resistant to wear, stains, and scratches, making it an enduring flooring option that requires little upkeep.

• Low Maintenance: Ideal for busy environments, it minimises the time and cost spent on maintenance, making it perfect for commercial areas or high-traffic residential spaces.

• Aesthetic Appeal: Its smooth, glossy surface not only enhances the aesthetics of any space but also improves light reflectivity, boosting natural lighting and creating a brighter atmosphere.

• Eco-Friendly and Allergy-Friendly: By utilising existing concrete slabs, burnished concrete reduces waste, and the absence of harsh chemicals or carpeting contributes to better indoor air quality.

• Customisation: Offering various design possibilities, burnished concrete can be tailored to suit unique styles and preferences, making it a versatile option for a range of applications.

• Quick Installation: The burnishing process is relatively fast, minimising downtime and allowing for quick project completion.

Burnished concrete floor cons

While burnished concrete floors offer numerous advantages, there are a few drawbacks to consider before making a final decision.

• Poor Heat Retention: One of the main drawbacks of burnished concrete is its inability to retain heat effectively. As a result, the surface can feel cold and uncomfortable, especially during the winter months. This can be particularly noticeable in spaces without underfloor heating, making it less suitable for colder climates.

• Porosity and Water Seepage: If the concrete is not properly polished and sealed, it can become porous, allowing water to seep through. This can lead to staining, mold growth, or even structural damage over time. Ensuring proper sealing and maintenance is critical to avoid these issues and protect the longevity of the floor.

• Noise: Burnished concrete floors, while sturdy and durable, can be noisy to walk on. The hard surface tends to amplify sounds, making it less ideal for spaces where noise reduction is important, such as bedrooms or areas requiring quiet work environments. The sound of footsteps, particularly in larger spaces, can become more pronounced without the cushioning of rugs or other materials.

Burnished vs polished concrete cost

The cost of burnished concrete compared to polished concrete can vary depending on several factors, including your location, the size of the project, the condition of the existing concrete, and the complexity of the design. In general, polished concrete tends to be more expensive due to the extra steps and time involved in the polishing process.

While burnished concrete and polished concrete may appear similar at first glance, they are achieved through distinct processes. Burnished concrete involves applying heat, melting, and buffing a chemical coating onto the surface, rather than grinding down the existing concrete substrate. This method is quicker and requires fewer steps, making burnished concrete a more cost-effective option. Additionally, chemical densifiers can be applied to burnished concrete to achieve a level of durability comparable to polished concrete.

In contrast, polished concrete requires multiple stages of grinding, honing, and polishing the concrete surface. This more intricate process requires specialised equipment and skilled labour, contributing to higher labour costs and longer project timelines. The result is a highly reflective, glossy finish, but the additional effort involved can make polished concrete significantly more expensive than burnished concrete.

Ultimately, the cost difference between these two options will depend on the specific requirements of your project. Burnished concrete is generally the more budget-friendly choice.

Cost Comparison: Polished Concrete vs Burnished Concrete Cost

Here’s a rough breakdown of the cost differences between burnished and polished concrete:

• Burnished Concrete Costs
  Burnishing typically involves fewer steps and less labour compared to polishing, making it a more cost-effective option.
  Cost of burnished concrete: $30 to $85 per square metre, but can be as much as $150 per square metre.

• Polished Concrete Costs
  Polished concrete requires more intensive grinding, honing, and polishing processes, which can increase both labour and material costs.
  Cost of polished concrete: $60 to $120 or more per square metre, but can be as much as $180 per square metre.

These cost estimates are general guidelines and can vary significantly based on specific project details and local market conditions. Larger projects may be more cost-effective on a per-square-metre basis, while smaller projects may have higher costs due to setup and minimum labour requirements.

Hiring a concreter and getting quotes

When getting an accurate cost estimate for your burnished concrete project, it’s important to reach out to local concrete contractors and request detailed quotes. Contractors can provide pricing based on several factors, including the scope of work, the condition of your existing concrete surface, and any customisation or design preferences you may have. Follow these steps when hiring a concreter and obtaining quotes:

• Research local contractors: Look for professionals with experience in burnished concrete flooring.

• Request multiple quotes: Get at least three quotes to compare prices and services.

• Provide project details: Include the size of the area, condition of the existing concrete, and any customisation or design preferences.

• Check experience and workmanship: Ensure the contractor is skilled and uses high-quality materials.

• Check reviews and references: Look for positive feedback and strong references from previous clients.

• Discuss timelines and payment terms: Clarify project duration and payment schedules.

Investing in high-quality workmanship ensures the longevity and appearance of your floor, making it well worth the upfront cost.
