Epoxy is often a practical choice for dry spaces requiring a strong, seamless, easy-to-clean finish. Certain PU systems, particularly PU cement, may be better suited to wet areas or significant temperature changes. Actual performance depends on formulation, thickness, substrate preparation and operating conditions.
What is epoxy flooring?
Epoxy flooring uses resin and hardener components that cure to form a continuous surface. Systems range from thin coatings to thicker self-leveling finishes and can suit warehouses, production spaces and other facilities when correctly specified.
What is polyurethane (PU) flooring?
PU flooring refers to several different formulations, including coatings, self-leveling systems and PU cement. These are not interchangeable. The selection should account for temperature, moisture, chemicals, cleaning methods and daily operational loads.
Epoxy vs PU: At-a-glance comparison
| Factor | Epoxy | PU / PU Cement |
|---|---|---|
| Typical strengths | Seamless finish, solid surface and many coating options | Formulations available for different flexibility and durability requirements |
| Site conditions | Often selected for relatively dry, stable-temperature areas | Some PU cement systems are designed for wet zones and thermal changes |
| Chemicals and heat | Depends on the resin grade, concentration and exposure duration | Depends on the exact formulation; certain PU cement systems target demanding environments |
| Cost | Varies with coating type, thickness and preparation | Varies with formulation, thickness and jobsite conditions |
How to choose the right system
1. Warehouses and traffic areas
Consider rack loads, forklift traffic, wheel types, impact and the condition of the concrete. A properly specified epoxy system may work well, but abrasion and impact resistance should be evaluated.
2. Food-processing or washdown areas
Evaluate hot-water cleaning, chemical exposure, slip resistance, drainage and hygiene requirements. PU cement may warrant consideration but is not automatically the best answer for every food facility.
3. Areas emphasizing appearance and easy cleaning
Compare appearance, gloss, scratch resistance, repair needs and the downtime available for installation.

Frequently asked questions
Is epoxy or PU more durable?
Neither system wins in every situation. Compare the exact product formulation, applied thickness and expected exposure to moisture, heat, impact and chemicals.
Can a new coating go straight over an existing floor?
Not without assessment. Adhesion, moisture, cracks and contamination must be checked, and appropriate substrate preparation is essential.
How long will the facility need to close?
Downtime depends on the selected system, site temperature and humidity, and when different load levels can safely resume. Follow the relevant technical data sheet.
