Monarflow PU is a water-based polyurethane self-smoothing resin flooring system designed for heavy-duty usage in harsh industrial environments. Applied at around 6 mm thickness, it produces a smooth matt finish that levels the substrate, evens out imperfections, and delivers a durable, hygienic surface.
With high chemical and abrasion resistance, resistance to thermal shock, and the ability to withstand aggressive cleaning regimes, Monarflow PU is widely used in food and drink manufacturing, pharmaceutical processing, automotive and aviation production, laboratories, and heavy-duty traffic areas. Its seamless finish is food safe, non-tainting, and easy to sanitise — making it suitable for environments where hygiene is critical.
Monarflow PU is a heavy-duty polyurethane resin system specifically designed for industrial environments where durability and performance are critical. Applied as a seamless, self-smoothing finish, it levels the substrate to create a smooth matt surface that is both functional and visually consistent. The system offers exceptional resistance to chemicals, oils, fuels and cleaning agents, while its abrasion resistance and impact tolerance make it ideal for areas subject to constant traffic or heavy-duty operations.
Unlike many alternatives, Monarflow PU is formulated to withstand thermal shock and is resistant to hot water cleaning up to 70 °C, ensuring long-term reliability even in harsh conditions. It is also food safe, non-tainting and hygienic, making it a trusted choice in the food, beverage and pharmaceutical sectors.
With a low-VOC formulation that meets recognised indoor air quality standards, and availability in a range of standard greys or extended RAL colours, Monarflow PU provides both performance and versatility for demanding industrial flooring projects.
Monarflow PU is ideally suited to food and drink production, pharmaceutical processing and other industrial environments where hygiene, durability and performance are critical. Its seamless matt finish, combined with chemical, abrasion and thermal shock resistance, makes it a reliable flooring solution for areas exposed to heavy traffic, hot water cleaning and strict hygiene standards.
Monarflow PU is widely chosen as a heavy-duty polyurethane resin flooring system for its chemical and abrasion resistance, thermal shock tolerance, and seamless matt finish. While it offers excellent durability, hygiene and performance benefits, not all of these advantages will apply in every situation, as results can vary depending on the manufacturer, the substrate and the quality of installation.

Disclaimer: The information above is provided as a broad general guide for the Monarflow PU product. Please check the latest Technical Data Sheet (TDS) and Material Safety Data Sheets (SDS), and consult our technical team before specifying or ordering. Manufacturing developments may result in changes before this website is updated.
Is Monarflow PU the same as epoxy?
No. While both are resin flooring systems, PU generally provides better chemical and thermal resistance than epoxy.
How thick is Monarflow PU applied?
It is normally applied at 4–6 mm thickness, with 6 mm recommended for harsh or heavy-duty environments.
Can Monarflow PU be used in food and drink facilities?
Yes — it is food safe, non-tainting and easy to sanitise, making it well-suited for food, drink and pharmaceutical industries.
What about thermal and hot water resistance?
Monarflow PU withstands thermal shock and is resistant to hot water cleaning/spillage up to 70 °C, and suitable for freezer conditions down to −15 °C.
How soon can the floor be used after installation?
At 20 °C, the system is typically:
Pedestrian traffic: 12 hours
Light wheeled traffic: 24 hours
Heavy traffic: 48 hours
Full chemical resistance: 7 days
As shown above, Monarflow PU is a durable polyurethane resin flooring system that provides a seamless matt finish and reliable long-term performance. It is designed to withstand heavy traffic, chemical exposure, thermal shock and hot water cleaning, making it ideally suited to food and drink manufacturing, pharmaceutical processing, laboratories, warehouses and other demanding industrial environments. Monarflow PU is available in a range of standard greys, with extended RAL colour options available to order, ensuring both performance and design flexibility.
