Polished Concrete Cost Per Sq Metre? (5 Quotes!)

Have you ever walked into a space and been captivated by the sleek, shiny surface of polished concrete flooring?

Whether it’s a chic café, a modern office, or a stylish home, polished concrete has become increasingly popular for its aesthetic appeal and durability.

However, as with any renovation or construction project, understanding the costs involved is crucial. So, what exactly can you expect to pay for polished concrete per square metre? Let’s dive in!

1. Understanding Polished Concrete

What is Polished Concrete?

Polished concrete isn’t just slapping some glossy stuff on a slab. It’s a multi-stage process where concrete is mechanically ground, honed, and polished with specialized equipment and abrasives.

Think of it like sanding wood, but on a much larger and tougher scale. The goal is to achieve a smooth, reflective surface that’s both beautiful and incredibly durable.

Why Choose Polished Concrete?

As a flooring contractor with years under my belt, I’ve seen trends come and go. But polished concrete? It’s got staying power. Here’s why:

• Durability: This stuff is tough! It can withstand heavy foot traffic, equipment, and everyday wear and tear. I’ve seen it last for decades in commercial settings.
• Low Maintenance: Forget about waxing or special cleaners. Polished concrete is easy to clean with just soap and water.
• Aesthetics: From matte to high-gloss, you can customize the look to match your style. Plus, you can add stains, dyes, or even decorative aggregates for a unique touch.
• Sustainability: If you already have a concrete slab, you’re essentially recycling it. This reduces the need for new materials and minimizes waste.

Where Can You Use It?

I’ve installed polished concrete in all sorts of places:

• Residential: Homes, apartments, and condos. It’s great for living rooms, kitchens, and basements.
• Commercial: Retail stores, restaurants, offices, and warehouses.
• Industrial: Factories, manufacturing plants, and distribution centers.

Basically, anywhere you need a durable, low-maintenance, and attractive flooring option.

2. Factors Influencing Cost

Alright, let’s get down to the nitty-gritty: how much will this actually cost you? The price of polished concrete per square metre can vary quite a bit depending on several factors. Here’s a breakdown:

Preparation of the Subfloor

This is HUGE. A solid foundation is absolutely critical. If your existing concrete slab is cracked, uneven, or damaged, it needs to be repaired before any polishing can begin.

I’ve seen projects where the subfloor prep doubled the overall cost. Why? Because grinding down high spots, filling cracks, and leveling the surface takes time, labor, and specialized equipment.

• Cracks: Small cracks can be filled with epoxy or concrete patching compounds. Larger cracks may require more extensive repairs, like crack chasing and filling with a flexible sealant.
• Unevenness: Self-leveling concrete overlays can be used to create a smooth, level surface.
• Existing Coatings: If there are old coatings like paint, epoxy, or adhesives, they need to be removed before polishing. This can be done with chemical strippers or mechanical grinding.

Quality of Materials

Not all concrete is created equal. The type of concrete mix, the aggregate used, and the finishing techniques all affect the final result. Also, the quality of the polishing compounds, sealers, and densifiers used will impact the longevity and appearance of the floor.

• Concrete Mix: A high-quality concrete mix with a higher PSI (pounds per square inch) rating will be more durable and polishable.
• Aggregates: The type and size of aggregates (like gravel or stone) can affect the appearance of the polished concrete. Some people prefer a more exposed aggregate look, while others prefer a smoother, more uniform surface.
• Polishing Compounds: High-quality polishing compounds will produce a better shine and protect the concrete from staining and wear.
• Sealers and Densifiers: These products harden the concrete and make it more resistant to moisture and chemicals.

Polishing Process

The polishing process itself involves multiple stages of grinding and polishing with progressively finer grits of diamond abrasives. The more steps involved, the higher the cost.

A basic polish might involve only a few steps, while a high-gloss, mirror-like finish could require a dozen or more.

• Grinding: This is the initial stage where the concrete is ground down to remove any imperfections and expose the aggregate.
• Honing: This stage uses finer grits to smooth out the surface and prepare it for polishing.
• Polishing: This is the final stage where the concrete is polished to the desired level of shine.
• Densifying: A densifier is applied to harden the concrete and make it more resistant to wear and tear.
• Sealing: A sealer is applied to protect the concrete from staining and moisture.

Labour Costs

Expertise matters. An experienced contractor will not only do a better job but also be able to identify potential problems early on and avoid costly mistakes. Labour costs vary depending on the region and the contractor’s skill level.

I’ve seen DIY attempts go horribly wrong, resulting in uneven surfaces, swirl marks, and other imperfections that are difficult to fix. Trust me, it’s worth paying for a professional.

Geographical Location

Like any service, prices vary depending on where you are. Major metropolitan areas tend to have higher labor costs than rural areas. Also, market demand can play a role. If polished concrete is a popular trend in your area, contractors may be able to charge more.

3. Average Costs for Polished Concrete

Okay, so what are we actually talking about here? As a rough estimate, you can expect to pay anywhere from $30 to $120 per square metre for polished concrete.

This is a wide range, I know, but it really depends on all the factors I mentioned above.

Here’s a more detailed breakdown:

• Basic Polish (Matte Finish): $30 – $60 per square metre. This typically involves minimal grinding and polishing.
• Mid-Range Polish (Satin Finish): $60 – $90 per square metre. This includes more extensive grinding and polishing to achieve a smoother, more reflective surface.
• High-End Polish (High-Gloss Finish): $90
  • $120+ per square metre. This requires multiple stages of grinding and polishing to achieve a mirror-like shine.

Keep in mind that these are just averages. Your actual cost may be higher or lower depending on your specific project.

5. Cost Comparisons with Other Flooring Options

Okay, so polished concrete can be a bit pricey. How does it stack up against other flooring options? Let’s take a look:

As you can see, polished concrete can be more expensive than some options like vinyl or carpet, but it’s often comparable to hardwood or tile.

However, it’s important to consider the long-term value. Polished concrete is incredibly durable and requires very little maintenance, which can save you money in the long run.

Here’s a quick comparison of long-term costs:

• Polished Concrete: Low maintenance, long lifespan (50+ years). Minimal replacement costs.
• Hardwood: Requires regular refinishing, can be damaged by moisture. Higher replacement costs.
• Tile: Can crack or chip, grout requires regular cleaning and sealing. Moderate replacement costs.
• Vinyl: Less durable, prone to scratches and dents. Lower replacement costs, but needs to be replaced more often.
• Carpet: Requires regular cleaning, can stain easily. Lower replacement costs, but needs to be replaced frequently.

6. Case Studies

Let’s look at some real-world examples to see how polished concrete can be used in different settings:

7. Conclusion

So, what’s the bottom line? Polished concrete can be a fantastic flooring option, but it’s important to understand the costs involved.

The price per square metre can vary depending on a number of factors, including the preparation of the subfloor, the quality of materials, the polishing process, labor costs, and geographical location.

While polished concrete may be more expensive than some other flooring options upfront, it offers excellent long-term value due to its durability, low maintenance, and aesthetic appeal.

My advice? Get multiple quotes from local contractors and ask lots of questions. Make sure they understand your specific needs and can provide a detailed breakdown of the costs involved.
