Types of Polished Concrete Finishes
Auckland’s construction scene boasts a variety of polished concrete finishes, allowing homeowners to select an option that complements their home’s design and functionality needs. Each type comes with its unique style, texture, and colour variations.
Let’s delve into the diverse range of polished concrete finishes available:
Grind and Seal:
- Description: This method involves grinding the concrete’s surface and then sealing it with a high-gloss or matte sealer.
- Design Variations: You can achieve both a glossy mirror-like finish or a satin matte appearance, depending on preference.
- Texture: The concrete can either be ground down for a smoother feel or left slightly coarse.
- Colours: Natural grey is the most common, but tints can be added during the sealing process for a splash of colour.
Cream Polish:
- Description: It capitalises on the creamy part of the concrete to give a smooth and consistent finish.
- Design Variations: Offers a very uniform appearance without exposing aggregate.
- Texture: Extremely smooth to the touch.
- Colours: Predominantly maintains the concrete’s original colour, offering a muted and minimalistic look.
Salt and Pepper Polish:
- Description: By lightly grinding the concrete surface, small aggregates or ‘fines’ are revealed, giving a subtle speckled appearance.
- Design Variations: The speckles can range from dense to sparse, based on grinding depth.
- Texture: Mostly smooth with slight texture from the small aggregates.
- Colours: Natural concrete colour with hints from the exposed fines.
Exposed Aggregate Polish:
- Description: Here, the concrete is ground down significantly to reveal larger aggregates or stones within.
- Design Variations: From river pebbles to crushed granite, the choice of aggregate can deeply influence the final look.
- Texture: The texture can be somewhat rugged due to the protruding aggregates.
- Colours: Varies widely based on the colour and type of chosen aggregates.
Dyed and Stained Polishes:
- Description: Post the polishing process, dyes or stains can be applied to add vibrant colours or unique designs.
- Design Variations: Possibilities are endless – from solid colours, gradients to intricate patterns.
- Texture: Varies depending on the underlying polish method.
- Colours: A wide spectrum from earthy browns and greens to vibrant reds and blues.
Terrazzo Finish:
- Description: This is an ancient technique where chips of marble, granite, or glass are embedded into the concrete, and then it’s polished up.
- Design Variations: Can range from minimalistic with sparse chip distribution to a dense and intricate design.
- Texture: Smooth with slight interruptions from the embedded chips.
- Colours: Extremely versatile depending on the choice of chips and the concrete’s base colour
Auckland’s dynamic construction landscape and its residents’ diverse preferences ensure there’s a polished concrete finish for every taste and requirement.
Sustainability and Environmental Concerns
When assessing polished concrete floors from an environmental standpoint, there are numerous benefits to be highlighted. Auckland residents not only get a sleek and contemporary finish but also contribute positively to the environment.
Here’s a deeper look into the sustainability aspects:
- Durability: One of the standout features of polished concrete is its resilience.
- Long-lasting: Once installed and maintained properly, polished concrete floors can last a lifetime, reducing the need for replacements.
- Reduction in waste: With fewer replacements, there’s a notable decrease in construction waste. No need to discard old carpets, tiles, or wooden boards.
Material Source:
- Local procurement: A significant amount of concrete used in Auckland constructions is locally sourced. This not only ensures quality but dramatically reduces the carbon emissions linked to transporting materials from distant places.
- Recycled aggregates: Many polished concrete solutions incorporate recycled aggregates, promoting circular economies and reducing the strain on natural resources.
Energy Savings:
- Natural reflectivity: The reflective surface of polished concrete optimises natural light, decreasing the need for artificial lighting and thereby reducing energy consumption.
- Thermal properties: In Auckland’s varied climate, polished concrete can retain heat during cooler months and stay relatively cool in the warmer season, leading to potential savings on heating and cooling costs.
Chemical Reduction:
- Low VOCs: Polishing concrete doesn’t require volatile organic compounds (VOCs) like some other flooring options. VOCs can be harmful to indoor air quality and overall well-being.
- Fewer cleaning agents: A seasoned concrete surface is easy to clean and doesn’t necessitate strong chemical agents, ensuring indoor environments remain healthier.
Water Conservation:
- Reduced water in maintenance: Unlike other floors that might need regular mopping or specialised cleaning procedures, polished concrete floors require minimal water for maintenance.
- Permeable options: Some concrete solutions allow water to percolate, reducing run-offs and recharging groundwater levels.
For Aucklanders, the choice of polished concrete isn’t merely an aesthetic or financial decision. It’s a commitment to sustainability and a step towards building a greener future.
Floor Polishing Costs in Auckland
Understanding the financial aspect is crucial. Here’s a breakdown to provide some clarity:
- Grind and Seal: This tends to be more economical, with prices ranging around NZD $70-$95 per square metre. It offers a balance between aesthetics and affordability.
- Honed Concrete: A favourite for outdoor areas, it generally costs between NZD $95-$130 per square metre.
- Mechanical Polishing: The most luxurious option, the price can start from NZD $130 and can go upwards depending on the level of finish desired.
However, remember to consult a floor polishing contractor for precise quotations, as factors like the state of the current surface and the total area can influence costs.
Health, Safety, and Polished Floors
Polished concrete floors, while aesthetically pleasing, also bring with them an array of health and safety considerations, especially in Auckland’s varied climate and building structures. Let’s examine some vital health and safety aspects to be aware of:
Slip Resistance:
- Concern: Polished concrete floors, especially when wet, can become slippery. This can pose a hazard in areas prone to spills or moisture.
- Solution: Opt for finishes with added texture or incorporate anti-slip additives. Regular maintenance and ensuring the floor is clean from spills can further reduce this risk.
Maintenance and Cleanliness:
- Concern: Dust and allergens can accumulate on any flooring surface, potentially impacting indoor air quality.
- Solution: One of the merits of polished concrete is its ease of maintenance. Regular sweeping and occasional damp mopping can keep the floor pristine, reducing allergen build-up and promoting a healthier indoor environment.
Chemical Use:
- Concern: During the polishing process or when applying sealants, harmful chemicals might be used.
- Solution: Always choose eco-friendly, low-VOC (volatile organic compounds) products. These are safer for both the applicator and the inhabitants of the space.
Ergonomics and Comfort:
- Concern: Concrete floors can be hard on the joints if one stands or walks on them for extended periods.
- Solution: If the space is intended for prolonged standing or walking (like retail spaces), consider integrating padded mats in high-traffic areas or advising occupants to wear cushioned footwear.
Reflectivity and Glare:
- Concern: Highly polished floors can sometimes reflect sunlight or indoor lighting, causing glare that might be uncomfortable or disorienting.
- Solution: Opt for a matte or semi-gloss finish. If the glossy finish is non-negotiable, strategically placing rugs or furniture can break up the reflection. Adjusting indoor lighting can also help mitigate this concern.
Temperature Conductivity:
- Concern: Concrete floors can feel cold, especially during Auckland’s winter months, which might not be comfortable for some.
- Solution: Consider incorporating underfloor heating during installation. Not only does this provide a comfortable surface to walk on, but it also aids in warming up the space, leading to potential energy savings.
Acoustics:
- Concern: Hard surfaces like concrete can sometimes amplify sounds, leading to echo or noise concerns, especially in open spaces.
- Solution: Integrate soft furnishings like rugs, curtains, or acoustic panels to absorb sound and enhance the acoustical comfort of the space.
Awareness and proactive planning can mitigate most health and safety concerns associated with polished concrete floors. The key lies in understanding the unique requirements of your space, the needs of its occupants, and tailoring your choices accordingly.
