Central Coast food businesses, cafes, restaurants, bakeries, takeaways, food manufacturing facilities, and commercial kitchens, are required to maintain floors that are cleanable, impervious, and non-slip. The NSW Food Authority and Safe Food NSW enforce these requirements under the Food Standards Code and Australia New Zealand Food Standards Code Standard 3.2.3. A cracked, unsealed, or porous concrete floor in a food business is a compliance failure waiting to become an infringement notice or a closure order.
The good news: quality epoxy and polyurethane floor coating systems meet all food safety, hygiene, and slip resistance requirements and can be applied over existing concrete with minimal disruption to your operation.
What the Regulations Require
NSW Food Authority, Floor Requirements
Under Standard 3.2.3 (Food Premises and Equipment) of the Australia New Zealand Food Standards Code:
Food premises must be designed and constructed in a way that (a) floors, walls, ceilings and other structures are easy to clean and, where necessary, to disinfect.
For floor surfaces in food handling areas, the practical requirements are:
| Requirement | Compliance Standard |
|---|---|
| Impervious surface | No penetration of liquids into the substrate |
| Smooth and cleanable | No open texture that traps food or harbours organisms |
| Non-slip | Wet slip resistance ≥ PTV 36 minimum; ≥ PTV 45 recommended |
| Coved junctions | Floor/wall junctions must be coved to prevent buildup |
| Chemical resistance | Resistant to cleaning chemicals in use |
| Durable under food traffic | Must not degrade under pedestrian and equipment traffic |
Important: The floor surface does not need to be white, any colour is acceptable. The requirement is functionality, not colour.
HACCP Principles
HACCP (Hazard Analysis and Critical Control Points) plans, which are required for most commercial food manufacturing operations, include the floor surface as part of the physical environment assessment. A floor that is pitting, cracking, or losing its coating is a documented hazard, bacteria can colonise cracks and damaged areas that can’t be cleaned effectively.
Floor coating installation or resurfacing should be documented as a corrective action in the HACCP plan and inspected as part of regular verification audits.
Common Problems with Existing Food Business Floors
Bare or Lightly Sealed Concrete
Bare concrete and lightly sealed concrete are porous, liquids (cleaning water, meat juices, cooking oils, sauces) penetrate the surface and cannot be fully removed. This creates a chronic contamination issue that deepens over time as the pores fill with organic matter.
Cracked Floors
Cracks in food production areas create a trap for food particles and moisture where bacteria can proliferate. Cracks are specifically called out in food safety inspections and are a common item on improvement notices.
Old Epoxy with Worn or Delaminating Coating
Epoxy floor coatings in commercial kitchens wear under constant foot traffic, equipment wheels, and chemical cleaning. When the coating wears thin or begins to delaminate, it creates the same hygiene problem as bare concrete, and adds the risk of coating fragments entering the food production stream.
Worn and delaminating coatings must be stripped completely before re-application.
Poor Drainage and Standing Water
Standing water in a food area is a hygiene risk and a slip hazard. The floor must drain effectively to floor waste drains. If existing drainage falls are incorrect, causing water to pool, a floor resurfacing with a self-levelling screed can correct the falls as part of the repair scope.
Floor Coating Systems for Food Businesses
Standard Epoxy System (Most Common)
A 3-coat system consisting of:
- Epoxy primer: Low-viscosity, penetrates concrete pores for strong mechanical bond
- Epoxy mid coat (body coat): High-build, creates the primary impervious layer
- Polyurethane or polyaspartic topcoat: Improved UV stability, chemical resistance, and non-slip texture
Total dry film thickness: 300-600 microns (µm)
Why polyurethane over epoxy for the topcoat: Pure epoxy topcoats yellow under UV (from kitchen lights and windows) and are slightly more brittle. A polyurethane topcoat maintains colour better, has improved abrasion resistance, and is slightly more flexible, better handling thermal cycling in commercial kitchens.
Cost: $35 to $65 per m² on prepared substrate
Lifespan: 10-15 years in commercial kitchen environments with proper maintenance
Heavy-Duty Polyurethane Cementitious System
For food processing floors subject to heavy traffic, high-temperature cleaning (steam cleaning, 80°C+ washdown), thermal shock, and high chemical exposure:
- Polyurethane cementitious screed (6-9 mm): A hybrid product combining the toughness of polyurethane with the compressive strength of cement. Creates a very thick, highly durable surface
- Specifically designed to withstand thermal shock (boiling water poured on a cold floor)
- Provides inherent anti-microbial properties in some formulations
Best for: Food manufacturing, meat processing, commercial bakeries, institutional kitchens
Cost: $60 to $120 per m² on prepared substrate
Lifespan: 15-25 years
Polyaspartic System (Fast Return to Service)
For food businesses that need the fastest possible return to service:
- Full system applied in a single day
- Return to foot traffic in 4-6 hours; full chemical resistance at 24 hours
- UV stable (unlike epoxy)
- Good chemical resistance
Best for: Cafes and food businesses where closing for more than 24 hours is not operationally feasible
Cost: $50 to $90 per m²
Lifespan: 10-18 years
Slip Resistance in Food Environments
Commercial kitchens are among the highest-risk environments for slip injuries, wet floors, oil contamination, and people moving quickly with heavy loads. Safe Work Australia data shows kitchen slips are a major category of workplace injury.
The minimum PTV for commercial kitchen floors under wet conditions is 36 (Class P3), but the recommended standard is PTV ≥ 45 (Class P4) in wet service conditions. For areas where oil, grease, or cooking fat is regularly present on the floor, PTV ≥ 55 is the target.
Non-slip is achieved through:
- Coarse aggregate broadcast: Aluminium oxide or quartz broadcast into the wet topcoat provides a textured surface with high PTV
- Anti-slip additives in the sealer: Fine non-slip additives mixed into the topcoat, less texture than broadcast but easier to clean
- Profile of the polyurethane cementitious screed: The inherent texture of a float-applied screed provides slip resistance without additives
Trade-off: Coarser texture = higher slip resistance = harder to clean. For food environments where daily cleaning is essential, a medium-texture profile balances hygiene and safety.
Installation Without Shutting Down, Staging Options
Most Central Coast food businesses cannot close for 3-5 days for a complete floor resurfacing. Staging is the solution:
Half-kitchen staging: Works in a single kitchen space, divide it down the middle. Install coating on one half, return to service, then coat the other half. Extends project by 2-3 days but maintains operation throughout.
Overnight work: Start at kitchen close (typically 10 pm) and work through the night, with the floor returning to service by opening (typically 6-7 am). This is achievable with polyaspartic or fast-cure polyurethane systems. Adds a 15-25% labour cost premium.
Weekend shutdown: If the business doesn’t trade Saturday/Sunday, a full kitchen floor can be coated Friday evening through Sunday with return to service Monday morning. This is the most efficient option where possible.
Section-by-section: For large food manufacturing facilities, a section-by-section approach over several weeks allows continuous operation.
Central Coast Food Business Locations
Commercial food operations across the Central Coast face the standard compliance requirements, plus:
Coastal humidity: High humidity in kitchens adjacent to the coast increases moisture vapour emission from concrete slabs, critical to measure before epoxy application. Gosford CBD, The Entrance foreshore hospitality strip, and beachside cafes at Terrigal and Avoca Beach are in higher-humidity environments.
Salt air: Kitchens with roller door openings facing prevailing sea breezes (particularly at beachfront venues) receive salt air that can affect coating adhesion if surface preparation is compromised.
Tourist-season trading patterns: Many Central Coast food businesses have dramatically different trading patterns between school terms and school holidays. Scheduling floor works for quieter periods, May, June or September school holidays when only partial business operates, can reduce the impact of any temporary closure.

Frequently Asked Questions
How long will my kitchen have to close for a floor resurfacing? For a standard café kitchen (30-80 m²), 2-3 days for a complete floor project with normal working hours. With overnight or split-shift work, this can be reduced to a single weekend. Fast-cure polyaspartic systems can achieve 6-hour cure times if full closure for 24+ hours is not possible.
My food business uses caustic cleaning agents, will the coating handle this? Epoxy and polyurethane systems are resistant to most common food industry cleaning chemicals at normal dilution, including sodium hypochlorite (bleach), caustic soda, and quaternary ammonium compounds. Always confirm the specific chemicals with the coating supplier, very high concentrations or uncommon chemicals may require a specialist formulation.
Will the floor need to be repainted if it gets chipped or damaged? Small localised damage can be spot-repaired with the same product. The repair will be visible if the coating colour has aged, but the hygiene function is restored. For consistent appearance, a full recoat every 8-12 years is typical for commercial kitchen floors with heavy traffic.
Do I need to notify the council or food authority before coating my kitchen floor? No specific notification is required for floor maintenance or resurfacing. If you’re undertaking broader fit-out changes that affect other parts of the food business, check whether a building consent or food business approval variation is needed.
Can the coating be applied over our existing cracked kitchen floor? Cracks must be repaired before coating. Cracks are filled and levelled as part of the contractor’s preparation scope. On a commercial kitchen floor, proper crack repair is a hygiene requirement, the coating over an unfilled crack will eventually crack at the same location and create a bacterial trap.
