If you’re planning a new floor for your Sydney business — whether it’s a bustling warehouse in Botany, a commercial kitchen in Surry Hills, a high-end retail store in the CBD, or a food processing plant in Western Sydney — you’ve probably run into the same question that stumps many business owners:
👉 Should I choose epoxy or polyurethane flooring?
At first glance, they seem similar:
- Both are seamless resin-based coatings.
- Both are highly durable.
- Both can be applied over concrete.
- Both are used in commercial and industrial environments.
But dig a little deeper and you’ll discover that epoxy and polyurethane (PU) floors are two very different animals — each with their own strengths, weaknesses, and ideal applications.
Choosing the right one isn’t just about budget or aesthetics, or even what an international manufacturer’s rep. is telling you — it’s about matching the floor to your business’s operational needs, compliance requirements, and future plans.
In this detailed guide, we’ll help you make the right choice:
✅ The key differences between epoxy and PU flooring
✅ The pros and cons of each system
✅ Where each system performs best in Sydney environments
✅ Typical costs
✅ How to avoid common specification mistakes
✅ Final recommendations based on YOUR type of business
The Basics: What Are Epoxy and Polyurethane Floors?
Let’s start with the basics:
Epoxy Flooring
- Made from epoxide resin + hardener
- Chemically cures to form a hard, durable, seamless surface
- Typically applied in multiple coats → 2–4mm total thickness
- Offers excellent chemical resistance, adhesion, and durability
- Very popular in warehouses, workshops, commercial kitchens, garages, retail spaces
Polyurethane Flooring
- Made from polyol + isocyanate components
- Cures to form an elastic, abrasion-resistant, chemically tough surface
- More flexible than epoxy → can handle thermal shock and dynamic movement
- Often thinner than epoxy (1–3mm), but highly resistant
- Used in food processing, breweries, freezers, loading docks, kitchens, some outdoor areas
Key Differences at a Glance
| Property | Epoxy | Polyurethane (PU) |
|---|---|---|
| Hardness | Very hard | More flexible |
| Impact resistance | High | Very high |
| Abrasion resistance | High | Extremely high |
| Chemical resistance | Very good | Excellent (better for acids) |
| Thermal shock resistance | Poor-moderate | Excellent |
| UV stability | Poor | Very good (with PU topcoat) |
| Installation complexity | Medium | Higher |
| Typical lifespan | 5–12 years | 8–15 years |
| Typical cost | Lower | Higher |
Where Epoxy Flooring Shines
1️⃣ Warehouses and Distribution Centres
✅ Excellent for forklift traffic
✅ Very durable under point loads and pallets
✅ Smooth or textured finish options
✅ Easy to mark pedestrian lanes and work zones
👉 Epoxy is the #1 choice for Sydney warehouses.
2️⃣ Workshops and Automotive Spaces
✅ Handles oils, grease, fuel spills well
✅ Resistant to abrasion from tools, jacks, equipment
✅ Tough and easy to clean
✅ Affordable compared to PU in these applications
👉 If you run a mechanical workshop in Sydney → epoxy is your best bet.
3️⃣ Retail and Showroom Floors
✅ Glossy, attractive finish
✅ Wide range of colours and effects (metallic, flake, solid colours)
✅ Excellent adhesion to prepared concrete
✅ Reasonable cost for high-end look
👉 Many Sydney retail spaces and showrooms choose epoxy for its appearance and cleanability.
Where Polyurethane Flooring Wins
1️⃣ Food & Beverage Production
✅ Excellent chemical resistance → especially to organic acids (fruit juice, dairy, vinegar)
✅ Can handle constant hot wash downs
✅ Tolerates thermal shock (steam cleaning, boiling water spills)
✅ Anti-microbial PU options available → ideal for HACCP-certified facilities
👉 If you run a brewery, dairy plant, food processing plant, or high-care kitchen → PU is often the superior choice.
2️⃣ Freezers and Cool Rooms
✅ PU floors tolerate extreme cold without becoming brittle
✅ Epoxy can crack under repeated freezing and thawing cycles
✅ PU stays flexible → maintains bond to substrate
👉 If your business uses freezer rooms, blast chillers, cold stores → choose PU.
3️⃣ Outdoor or UV-Exposed Areas
✅ PU topcoats are UV-stable → resist yellowing and chalking
✅ Epoxy alone will degrade quickly under Sydney sun
✅ PU can be used in loading docks, outdoor storage areas, semi-exposed patios
👉 For any area with direct sunlight exposure, PU is strongly preferred.
Pros and Cons
Epoxy Flooring
✅ Pros:
- Lower cost than PU
- Very hard, durable surface
- Great for light-moderate chemical environments
- Excellent appearance options
- Fast installation times
- Suitable for a wide range of applications
❌ Cons:
- Poor thermal shock resistance
- Can yellow if exposed to UV
- Less flexible → may crack on moving substrates
- Not ideal for wet-processing food areas
Polyurethane Flooring
✅ Pros:
- Exceptional chemical resistance → especially acids
- Handles hot water, steam, and thermal shock
- Extremely durable in wet and high-traffic areas
- UV stable (with correct topcoat)
- Flexible → tolerates minor substrate movement
- Excellent choice for food industry
❌ Cons:
- More expensive than epoxy
- More complex to install → longer cure times
- Less choice of decorative finishes
- Generally more industrial look → not as glossy as epoxy
Typical Costs in Sydney (2025)
| System | Approx. Cost per m² |
|---|---|
| Standard Epoxy | $70–$120 |
| High-build Epoxy | $90–$140 |
| Polyurethane (PU) | $110–$180 |
👉 PU is more expensive because it’s harder to install → but in harsh environments, it often saves money in the long run.
Common Mistakes to Avoid
👉 One of the biggest mistakes we see in Sydney is specifying the wrong floor system.
Here’s what NOT to do:
❌ Install epoxy in a brewery or dairy → acid + heat will destroy it
❌ Install epoxy in a freezer room → it will crack
❌ Install PU in a retail store → more expensive than needed + less aesthetic
❌ Install epoxy on an unprepared damp slab → will fail fast
Golden rule: Match the system to the application → not just the budget.
How to Choose for Your Sydney Business
Here’s a quick guide:
| Business Type | Recommended System |
|---|---|
| Warehouse / Distribution | Epoxy |
| Workshop / Garage | Epoxy |
| Retail Store / Showroom | Epoxy |
| Commercial Kitchen | PU Hybrid or Quartz-filled Epoxy |
| Brewery / Distillery | PU Hybrid |
| Food Processing | PU Hybrid or Antimicrobial PU |
| Cold Storage / Freezer | PU |
| Outdoor / Loading Dock | PU with UV topcoat |
👉 If your floor sees:
✅ Constant wetness
✅ Frequent high-temp cleaning
✅ Exposure to acids → choose PU.
👉 If your floor sees:
✅ Dry or light wet cleaning
✅ Forklifts or vehicles
✅ Mostly dry foot traffic → epoxy is often perfect.
Final Recommendations
✅ Both epoxy and polyurethane floors are excellent — but they excel in different environments.
👉 Choosing the wrong one can lead to expensive reworks and operational downtime.
✅ Epoxy is best for:
- Warehouses
- Workshops
- Retail
- General industrial spaces
✅ PU is best for:
- Food production
- Breweries
- Freezers
- Commercial kitchens
- Outdoor / semi-exposed areas
👉 Don’t let cost alone drive the decision → the right system will save money and stress in the long run.
