Introduction: Chemical Exposure Is the Silent Floor Destroyer

Every industrial facility — from manufacturing and processing plants to warehouses and workshops — faces risks from chemicals and spills. While equipment and storage materials receive plenty of attention, the flooring often goes overlooked.

Yet the floor is the first surface to absorb:

• chemical leaks
• fuel and oil spills
• corrosive liquids
• cleaning agents
• coolant runoff
• solvents
• battery acid
• industrial by-products

Bare concrete is no match for these substances. It stains, erodes, absorbs moisture, and gradually weakens — eventually leading to cracking, contamination, or structural issues. When floors fail, operations are disrupted, safety is compromised, and costs escalate rapidly.

This is why industrial-grade chemical-resistant coatings are essential.

Epoxy and polyurethane flooring systems are engineered to protect facilities from damage, ensure safety, support compliance, and extend the lifespan of industrial concrete.

Why Chemicals Damage Industrial Flooring

Understanding why chemical-resistant coatings are essential starts with understanding the vulnerability of untreated concrete.

Concrete Is Naturally Porous

Spills seep directly into the substrate, spreading contamination and weakening the matrix.

Chemicals Break Down Concrete

Acids, solvents, oils, and bases can chemically react with cement, causing:

• softening
• discolouration
• pitting
• surface breakdown
• loss of structural integrity

Fats and Oils Cause Long-Term Degradation

These substances penetrate deeply, creating hygiene issues and permanent odours.

Water and Moisture Accelerate Damage

Moisture expands and contracts within concrete, amplifying the damage caused by chemical exposure.

Repeated Spills Weakens the Surface

Even mild chemicals cause cumulative harm over time.

Without proper protection, the floor becomes a point of failure — impacting safety, operations, and compliance.

The Solution: Industrial-Grade Coating Systems

Epoxy and polyurethane coatings create a non-porous, seamless, chemically resistant barrier that protects concrete from spills, chemicals, and constant wear.

These resin systems form a tough film over the surface, preventing penetration and making the floor much easier to clean and maintain.

Wolffes uses two primary systems:

• Epoxy floor coatings
• Polyurethane (PU) floor coatings

Each offers unique advantages depending on the environment, chemical exposure, and mechanical loads.

1. Epoxy Flooring for Chemical Protection

Epoxy is widely used across industrial facilities due to its excellent chemical resistance, durability, and long-term performance.

Strengths of Epoxy in Chemical-Heavy Environments

High resistance to oils and fuels

Perfect for:

• mechanical workshops
• transport depots
• automotive manufacturing
• mining operations

Epoxy prevents staining and penetration, making spills easier to clean.

Strong resistance to solvents and cleaners

Epoxy holds up well against:

• degreasers
• industrial detergents
• alkaline cleaners
• solvent-based chemicals

Durability under heavy machinery

Forklifts, pallet jacks, and heavy static loads are no issue for epoxy due to its high compressive strength.

Long-lasting performance

Epoxy coatings can last years even under extreme operational pressures.

2. Polyurethane Flooring for Advanced Chemical & Thermal Protection

Polyurethane flooring offers chemical resistance as well, but shines in environments requiring greater flexibility, temperature tolerance, or acid resistance.

Strengths of Polyurethane in Harsh Chemical Environments

Superior resistance to organic acids

Ideal for:

• food processing
• beverage production
• dairies
• fermentation facilities
• agricultural applications

Organic acids break down standard concrete rapidly — PU withstands them easily.

Thermal shock resistance

Polyurethane can handle:

• hot washes
• steam cleaning
• heated spills
• chilling/freezing zones
• rapid temperature changes

Epoxy cannot tolerate extreme thermal shock as effectively.

UV stability

PU maintains colour and structural integrity even in outdoor or sun-exposed locations.

Flexibility under impact

It handles vibration, machinery movement, and substrate expansion better than epoxy.

Matching the Right Coating to the Right Chemical Exposure

Selecting the correct coating depends on what chemicals your facility handles. Most industrial clients fall into one of the categories below:

Category 1: Oils, Fuels & Hydrocarbons

Common in:

• workshops
• transport depots
• mining
• mechanical repair
• heavy equipment facilities

Best coating: Epoxy
Why: Outstanding resistance to petroleum-based products.

Category 2: Acids & Fermentation By-Products

Common in:

• food processing
• breweries
• wineries
• chemical manufacturing
• pharmaceutical facilities

Best coating: Polyurethane
Why: PU outperforms epoxy against organic acids and corrosive substances.

Category 3: Coolants, Solvents & Cleaning Chemicals

Common in:

• industrial manufacturing
• packaging plants
• fabrication workshops
• electronics facilities

Best coating: Epoxy or hybrid system
Why: Epoxy handles solvents well, PU adds thermal shock protection if needed.

Category 4: Temperature Extremes + Chemical Exposure

Common in:

• commercial kitchens
• cold storage
• freezers
• food production
• beverage bottling

Best coating: Polyurethane
Why: PU tolerates heat, cold, steam, and chemicals simultaneously.

Why Seamless Coatings Are Essential

Chemical-resistant coatings are not only about surface strength. Seamlessness is equally important.

Benefits of a Seamless Resin Floor:

• No joints or grout lines to trap chemicals
• No cracks that allow liquid penetration
• Easier cleaning and sanitisation
• No hiding spots for bacteria or mould
• No delamination around edges

A seamless floor prevents contaminants from entering the substrate and eliminates long-term hygiene risks.

Slip Resistance Matters, Too

Many chemicals — especially oils and fats — create slip hazards.

Epoxy and PU coatings can be customised with non-slip textures ranging from R10 to R13, depending on:

• the substance being handled
• cleaning frequency
• foot traffic
• wheeled equipment

For example:

• Workshops often need R10
• Processing lines may require R11 or R12
• Food production often needs R12 or R13

Wolffes ensures each environment receives the correct slip rating to meet WHS and operational demands.

Hybrid Floor Coating Systems

Many industrial sites require a combination of performance features — and that’s where hybrid systems deliver exceptional value.

A typical hybrid system includes:

• Epoxy basecoat for strength and adhesion
• Polyurethane topcoat for chemical, UV, and temperature resistance

This offers the advantages of both materials in one long-lasting system.

Hybrid systems are ideal for:

• manufacturing & assembly lines
• food and beverage facilities
• outdoor-access warehouses
• chemical zones
• multi-use industrial sites

Industries That Benefit Most from Chemical-Resistant Coatings

• Warehouses
• Transport depots
• Mechanical workshops
• Mining & resources
• Manufacturing
• Food & beverage production
• Cold storage
• Agriculture
• Chemical processing
• Pharmaceutical production

Each industry faces unique risks, and Wolffes tailors coatings to match the exact chemicals, loads, and operational conditions on site.

Final Thoughts

Chemicals and spills are unavoidable in industrial environments — but damage, contamination, and safety risks don’t have to be. Industrial-grade epoxy and polyurethane flooring provides a strong, seamless, and resistant barrier that protects your facility, extends the life of your concrete, and ensures safe, compliant operations.

Whether you’re dealing with oils, acids, solvents, coolants, cleaning agents, or temperature extremes, the right coating system will save money, reduce downtime, and boost long-term performance.
