Polyurethane (PU) coatings are two-component reactive resins which are characterized by their excellent mechanical and chemical properties. Thanks to their high abrasion and chemical resistance as well as their flexibity, they are ideally suitable for use in challenging environments such as the pharmaceutical industry, production halls, storage rooms, and garages or workshops. They also come in a number of colours and finishes to meet both functional and aesthetic requirements.
PU flooring can be applied in many sectors: in industry, warehouses, cleanrooms, the pharmaceutical industry, retail, showrooms, gyms, schools, hospitals, the hotel and catering industry, and many more.
High abrasion resistance: Extremely resistant to wear and ideal for heavy-duty surfaces.
Chemical resistance: PU-coatings offer excellent protection against chemicals such as oil, solvents and cleaning agents.
Flexibility: The coating remains flexible and resilient against cracks and spalling, even in cold temperatures.
UV-resistant: PU-coatings are UV-resistant and ideal for outdoors as they do not yellow or decompose.
Water and moisture resilient: Optimal protection against water and moisture, thus increasing the longevity of the coated materials.
No limits to its creative design: PU-coatings are available in a wide range of colours and finishes. The perfect choice for tailored designs.
Step by Step to a Professional PU Coating
Inspection of the specific substrate properties: pressure and adhesive resistance, moisture level, or any damage.
Substrate preparation (shot-blasting, grinding, and vacuuming).
Applying the primer.
Applying a leveling layer.
Applying the coating.
Depending on the system chosen and the specific requirements, several layers may need to be applied, e.g. standard-compliant sealing layer or an ESD layer.
A PU-coating mainly consists of polyoll and isocyanates which together form polyurethane polymers. Catalysts are added to expedite the chemical reaction between the main components and to control the curing process. Solvents control the viscosity of the coating and facilitate the application, whereby water-based systems can also be applied. Additives enhance specific features such as UV-stability, abrasion resistance, flexibility, and antimicrobial properties. Fillers and pigments are added to optimize the mechanical features and provide colour to the coating.
How long does it take to apply PU-coating?
Installing floor coating usually takes 3 to 12 days, depending on the type of coating and the respective project requirements. Careful planning and preparation can expedite the process and guarantee the procedure runs smoothly. The exact duration depends on various factors, such as the type of coating, the size of the area, the on-site conditions, and the specific requirements. To keep downtime at a minimum, we can work during production runs or production-free hours, i.e. at night or at weekends – a practical solution.
How much does a PU-coating cost?
The prices for professionally applied PU floors in a commercial or industrial area are between €15 and €500/m². The exact price depends on many different factors: the condition and preparation of the substrate, the sealing, the chemical, thermal, and mechanical requirements, the installation of drainage and concave fillets, working hours (e.g. night or weekend shifts), the standard-compliant design, cleanroom suitability, the desired certification as well as the warranty period and documentation. It is therefore not easy to quote a flat-rate price as costs vary depending on the project and requirements.
