We recommend classifying polyurethane-cement flooring systems according to system thickness and the type of finish coat.

The required thickness of an industrial floor is directly determined by the anticipated mechanical loads and operational exposures.

The thickness of a polyurethane-cement flooring system is selected based on the anticipated load conditions.

For light to moderate loads, coating systems with a thickness of 4 mm are applied.
For moderate to heavy loads, coating systems with a thickness of 4–6 mm are recommended.
For heavy to very heavy loads, coating systems with a thickness of 7–12 mm are applied.

Description

Polyurethane-cement flooring systems are a highly wear-resistant type of polymer flooring with enhanced performance characteristics, specifically engineered for extreme service conditions.
Polyurethane-cement coatings are designed for use in aggressive industrial environments, including food processing, pharmaceutical, and chemical manufacturing facilities.
Polyurethane cement is a composite material produced by mixing polyurethane resin, cementitious binders, and specialized additives that enhance the technical performance of the flooring system.
The coating combines the properties of cement and polymers, resulting in exceptional mechanical strength and minimal shrinkage. As a result, the system is capable of withstanding high mechanical and impact loads. Resistance to mechanical and impact stresses is particularly critical in industrial process environments.
The operational temperature range extends from –40 °C to +150 °C without deformation, allowing the system to be used in freezer and cold-storage areas. The surface is resistant to hot oil spills and is suitable for steam cleaning.
Water absorption is 0%. A key advantage of polyurethane-cement flooring systems is their vapour permeability.
Due to their vapour permeability, polyurethane-cement floors are not susceptible to osmotic pressure, which can cause coating debonding as a result of moisture transmission from the concrete substrate in cases of inadequate or absent waterproofing.

Advantages of polyurethane-cement flooring systems

PU Cement systems with a thickness from 4 mm are the only flooring solution in their category offering absolute resistance to aggressive chemical exposure. In this regard, they outperform even methyl methacrylate (MMA) systems.
Polyurethane-cement coatings are resistant to all cleaning agents and cleaning methods and provide complete impermeability to moisture.
High repairability: local repairs can be carried out within short timeframes without shutting down production processes.
Exceptional resistance to mechanical and impact loads, combined with a relatively low modulus of elasticity and absence of brittleness.
Excellent wear resistance, classified as AR 0.5 in accordance with European standards.
High thermal resistance. Due to the elasticity of polyurethane, the system withstands temperature fluctuations from –40 °C to +120 °C.
Anti-slip performance: slip resistance classified as R11, suitable for flooring installations in wet and humid environments.

Relative air humidity: not regulated.
Dew point on the surface: not regulated.
Temperature range of air, substrate, and material:Optimal: +17 to +23 °CPermissible: +10 to +30 °C

What the Client Should Know

What You Need to Know Before Choosing PU Cement

Rapid commissioning: the flooring system can be subjected to full service loads within 24 hours.
Higher initial installation costs of polyurethane-cement flooring systems are fully offset by their extended service life.
Due to their composition and operational advantages, polyurethane-cement floors are the most widely used flooring systems in the food industry. They represent an ideal solution for meat processing plants and dairy production facilities. The coating does not emit toxic substances and does not affect the taste or quality of food products, either during installation or throughout the service life of the floor, and remains resistant to aggressive chemicals even at high concentrations.
Polyurethane-cement coatings are a cost-effective solution due to their long service life, simplicity of installation, and short application times. This unique combination of properties inherent to polyurethane-cement systems has enabled their successful long-term use in the food industry, beverage production, pharmaceutical manufacturing, and the chemical industry.
The system is available in a wide colour range, tinted according to the standard RAL colour chart, allowing selection of any colour to meet client requirements. The service life of the coating is not less than 10 years.
