Choosing the right flooring is about finding a surface that fits your space, your lifestyle, and your budget. Whether you’re building from scratch, renovating a home, or upgrading a commercial space, polished concrete and epoxy flooring are two standout options that often get compared; and for good reason.
Polished concrete is all about bringing out the natural beauty of your existing slab by grinding it down and sealing it for a smooth, refined finish. Epoxy flooring is a resin coating applied over existing concrete to create a seamless, durable and customisable surface.
Choosing between them really comes down to how you’ll use the space, what kind of look you’re going for, and how much you’re willing to spend.
What Do Polished Concrete and Epoxy Flooring Have in Common?
Polished concrete and epoxy flooring may look different on the surface, but when it comes to performance, they share several key benefits.
Shared Benefits at a Glance
- Tough, long-lasting surface
- Easy to clean and maintain
- Seamless and hygienic finish
- Brightens interiors through light reflection
- Resistant to stains and spills (with proper sealing)
- Supports healthier indoor air quality
- Works in homes, shops, warehouses & beyond
Now that we’ve covered what they have in common, let’s look at what sets them apart.
Polished Concrete vs Epoxy Flooring (Unique Advantages of Each Solution)
Polished Concrete – Unique Benefits
Natural Aesthetic Appeal – Polished concrete highlights the beauty of the slab itself, creating a sleek, minimalist finish with stone-like character. Unlike epoxy, which relies on added pigments and decorative coatings, polished concrete offers a natural look without artificial embellishments.
Eco-Friendly & Sustainable – Because it makes use of your existing slab with minimal added materials, polished concrete is one of the most sustainable flooring options available. In contrast, epoxy flooring requires synthetic resins and chemical curing agents that involve more energy and manufacturing inputs.
No Coatings to Degrade – The polished finish is mechanically created within the surface of the concrete itself, so there’s no coating to peel, wear, or delaminate over time. Epoxy, on the other hand, depends on surface layers that can eventually degrade and require reapplication.
Thermal Mass for Energy Efficiency – Polished concrete can absorb and store heat, then slowly release it — helping regulate temperature in energy-efficient buildings. Epoxy lacks this thermal mass effect, acting more like a surface barrier than a passive heating or cooling aid.
Low VOCs (Volatile Organic Compounds) – Polished concrete emits minimal VOCs since it typically requires fewer chemical products. Epoxy flooring, while safe when cured, often involves higher VOC levels during application due to its chemical composition.
Concrete Dust Elimination – Polishing densifies the surface and prevents concrete dust from forming — a common issue with raw or worn concrete. While epoxy seals the surface to prevent dust too, it doesn’t structurally strengthen the slab in the way polishing does.
Extremely Long Lifespan – Polished concrete can last 20 years or more without the need for recoating, requiring only occasional buffing or resealing. Epoxy, though durable, may need a full recoat every few years in high-use or UV-exposed areas.
Low-Allergen Breathable Surface – The seamless, breathable surface of polished concrete doesn’t trap allergens and supports good indoor air quality. Epoxy also resists allergen buildup, but lacks the breathability of polished concrete, which can be a benefit in naturally ventilated spaces.
Epoxy Flooring — Unique Benefits
Exceptional Chemical Resistance – Epoxy is highly resistant to oils, acids, fuels, and solvents — making it ideal for industrial and automotive use. Polished concrete, even when sealed, is more vulnerable to chemical etching and staining in harsh environments.
Customisable Colours & Effects – Epoxy flooring offers full design freedom with colours, flake systems, metallic coatings, and even embedded branding. Polished concrete, by contrast, has a more neutral, natural appearance and limited aesthetic flexibility.
Built-In Slip Resistance – Anti-slip additives can be blended directly into epoxy finishes for enhanced safety in wet or high-risk environments. While polished concrete can also be treated with anti-slip solutions, it requires extra steps and isn’t as easily customisable for grip.
Fully Waterproof Barrier – Epoxy creates a seamless, non-porous surface that completely blocks moisture. Polished concrete is breathable and, unless sealed, can absorb water — which may not be suitable for damp or wet conditions.
Zoning & Visual Demarcation – Epoxy flooring allows for clear zoning with colours or line markings, useful in commercial and industrial environments. Polished concrete provides a uniform look but lacks the built-in capacity for visual demarcation.
Hygienic & Bacteria Resistant – The seamless, non-porous nature of epoxy makes it highly resistant to bacteria, mould, and odours — ideal for medical, animal care, and food prep areas. Polished concrete is also hygienic, but more porous and less resistant to organic contaminants without sealing.
Shock Absorption Options – Flexible epoxy systems can be formulated for comfort underfoot, helping reduce fatigue in environments with long standing periods. Polished concrete, while durable, is always a rigid surface with no give.
Rapid Surface Renewal – When it comes time to refresh, epoxy coatings can be sanded and recoated quickly, often with minimal disruption. Polished concrete resurfacing is more labour-intensive and requires specialist grinding equipment.
Now that you know the strengths of each, it’s worth seeing how they stack up side by side. The table below gives you a quick, easy comparison across key areas like performance, design, and maintenance.

As you can see, both options have their strengths — and the right pick really depends on your space, needs, and how you plan to use it. But before you make the call, let’s look at one of the biggest deciding factors: cost.
Cost Comparison
When it comes to flooring, price plays a big role in the final decision — and rightly so. Whether you’re renovating a home or upgrading a commercial space, understanding the cost differences between polished concrete and epoxy flooring will help you set a realistic budget and avoid any surprises.
Average Price Ranges in Australia (Per Square Metre)
- Polished Concrete: $50 – $120 per m²
On the lower end, you’re looking at a basic grind and seal finish — great if you’re after a simple, matte look. At the higher end, a full mechanical polish gives you that glossy, mirror-like finish that’s super durable and visually striking. - Epoxy Flooring: $30 – $100+ per m²
A standard solid-colour or flake epoxy finish will sit at the lower end of the scale. If you’re after something a bit fancier — like a metallic finish or a heavy-duty industrial-grade system — you’ll be paying towards the upper end.
So, while epoxy can be cheaper upfront, that depends heavily on the type of finish and the condition of your existing floor.
What Impacts the Cost?
Surface Preparation – No matter which option you choose, what lies beneath matters. If your slab is cracked, uneven, or covered in glue or old tile adhesive, it will need grinding, patching, or levelling before anything goes on top. That’s extra time and labour.
Finish Type – Not all finishes are created equal. A basic matte polish or single-layer epoxy will be more affordable than a high-gloss mechanical polish or decorative epoxy with flakes or metallic pigments. The more refined the finish, the higher the cost.
Coating Layers (Epoxy only) – Epoxy systems often involve multiple layers — primer, base coat, flake broadcast, clear topcoat — each adding time and material cost. More layers mean more durability, but they also mean a higher price tag.
Size of Area – Generally, the more space you’re covering, the better your rate per square metre. Installers often offer better value on large, open-plan areas compared to fiddly or small sections.
Access & Labour – Got a lot of tight corners, stairs, or tricky access? That can bump up labour costs. The more difficult it is to get equipment in and out or to move around the space, the longer the job will take, and the more you’ll pay.
Now that you’ve got a clear picture of the pricing, the next logical question is: which floor is right for you? Below, we’ve broken it down by common use cases to help you figure out which one will suit your home, workplace, or project best.
Which Flooring is Best For You?
Still unsure which option fits your space best? Here’s a closer look at how polished concrete and epoxy flooring stack up in different real-world scenarios.
Best for Homes
If you’re after a clean, modern look with a bit of natural texture, polished concrete is hard to beat. It’s low-maintenance, long-lasting, and looks right at home in open-plan living areas, minimalist kitchens, and even bathrooms — as long as it’s sealed properly.
Epoxy flooring, on the other hand, is better suited to utility areas like garages, workshops, or storage rooms. In main living spaces, some people find it a bit too glossy or synthetic in appearance.
Best for High-Moisture Areas
If you’re dealing with moisture, dampness, or frequent spills, epoxy flooring is the safer bet. It’s completely waterproof, seamless, and naturally resistant to mould and bacteria — perfect for bathrooms, basements, and commercial kitchens.
Polished concrete can hold up well in humid areas too, but it must be thoroughly sealed, and even then it remains a breathable surface rather than a truly waterproof one.
Best for Commercial Branding or Zoning
This is where epoxy really shines. If you’re fitting out a retail space, warehouse, or any branded environment, epoxy gives you the freedom to include bold colours, texture contrasts, safety lines, and even your company logo right into the floor.
Polished concrete, while stylish, doesn’t offer the same level of design customisation.
Best for Budget-Conscious Buyers
If you’re watching the bottom line, epoxy flooring is often cheaper upfront — especially for basic finishes. But it may require recoating every 5–10 years depending on wear.
Polished concrete, especially in a grind-and-seal finish, may cost more initially but offers greater long-term value if you want a surface that doesn’t rely on topcoats or frequent touch-ups.
Still unsure? This quick checklist is here to help you decide faster based on what your space really needs — think of it as your go-to cheat sheet for picking the right floor with confidence.

Frequently Asked Questions (FAQs)
Find simple answers to the most common questions about polished concrete vs epoxy flooring.
- Which is more durable: polished concrete or epoxy flooring?
Both are highly durable, but in different ways. Polished concrete is tough and abrasion-resistant, ideal for high-traffic areas, while epoxy offers excellent impact and chemical resistance, making it better for harsh environments like workshops or garages.
- Which flooring lasts longer overall?
Polished concrete typically has a longer natural lifespan, often lasting 20+ years without recoating. Epoxy flooring may need to be resurfaced every 5–10 years depending on usage and exposure.
- Are both flooring options waterproof?
Only epoxy is fully waterproof. It forms a sealed, non-porous surface that blocks moisture entirely. Polished concrete is breathable and may absorb moisture if not sealed properly, so it’s not ideal for consistently wet environments without additional treatment.
- Can both polished concrete and epoxy flooring be used in kitchens or bathrooms?
Yes, but with caveats. Epoxy is ideal for these areas due to its waterproof and hygienic properties. Polished concrete can be used if properly sealed, though it’s more prone to moisture absorption.
- Which is more affordable: epoxy flooring or polished concrete?
Epoxy is often more affordable upfront, especially for standard finishes. Polished concrete can cost more initially — particularly for a full mechanical polish — but it offers lower long-term maintenance if no recoating is needed.
- Can I DIY either flooring type?
Epoxy flooring can be DIYed with kits, though professional results are more reliable. Polished concrete is not as suited to DIY. It requires industrial equipment (which you could hire) and specialist skills for proper grinding and finishing (which you likely don’t have).
- Which is better suited for homes: polished concrete or epoxy?
Polished concrete is generally better suited to interior living spaces due to its natural, stone-like appearance. Epoxy works well in garages, utility areas, or spaces needing high resistance and colour customisation.
- Which offers more design flexibility?
Epoxy wins here. It can be customised with colours, flakes, textures, and even embedded logos. Polished concrete is more limited, typically offering a natural grey tone with exposure of aggregate depending on the finish.
- Can both floors crack over time?
Yes, both can crack — but for different reasons. Polished concrete may develop hairline cracks as part of natural slab movement. Epoxy may crack if applied over an unstable or poorly prepared substrate.
- Are both flooring types low maintenance?
Yes, both are easy to clean and maintain, but with different requirements. Polished concrete needs occasional buffing or sealing, while epoxy may require recoating depending on traffic levels and exposure to chemicals or UV.
- Are polished concrete and epoxy flooring safe for families and pets?
Yes — both are non-toxic once cured and easy to clean. Epoxy can include slip-resistant additives, while polished concrete can be treated to improve grip if needed.
- Which flooring type takes longer to install: polished concrete or epoxy?
Polished concrete generally takes longer, especially for full mechanical polishing, which can take up to 6 days or more depending on the area size. Epoxy flooring is quicker to apply (2–3 days), but curing may add another 2–5 days before the surface is ready for use.
- Will either installation create a lot of mess or disruption?
Both will cause some disruption. Polished concrete involves grinding, which creates dust and noise — even with dust control equipment. Epoxy is quieter but gives off strong odours during curing, requiring good ventilation and sometimes vacating the space temporarily.
- Do both floors require furniture and items to be removed before installation?
Yes. Both systems need a clear, clean surface to start. That means removing all furniture and ensuring the slab is bare, clean, and free of any existing coatings or adhesives.
- Are there extra costs if my space is hard to access or has stairs?
Yes. Both options may cost more if installers have to navigate tight corners, staircases, or poor access. Labour time increases, and setup becomes more complex, which can drive up the price.
Which One Should You Choose?
Polished concrete and epoxy flooring each bring their own strengths to the table.
Polished concrete offers a natural, long-lasting finish, while epoxy is best for waterproof, high-performance spaces. Each suits different needs.
In the end, it all comes down to your space, your style, and what you need your floor to do.
