Flowcrete Flowfresh HF LT - Solvent-Free, Industrial Polyurethane Concrete Screed

A 4-component, solvent-free, polyurethane concrete screed designed for heavy-duty industrial environments. This screed is formulated to offer superior chemical resistance, antimicrobial properties, and low temperature application. It provides a long-lasting surface with slip resistance and a hygienic finish, making it suitable for food, beverage, and pharmaceutical industries.

Where to Use

This product is suitable for use on concrete substrates, particularly in areas requiring high chemical resistance, such as food processing facilities, kitchens, and chemical plants. The slip-resistant texture makes it ideal for environments prone to liquid spills or wet conditions. Flowfresh HF LT is commonly used in industries where cleanliness and safety are paramount.

Why Choose Flowfresh HF LT

Flowfresh HF LT is not only resistant to harsh chemicals, but it also has an antimicrobial additive (Polygiene®), which inhibits bacterial growth, ensuring that the floor meets hygiene requirements. The product is certified to EN 13813 and HACCP International, guaranteeing its performance in regulated environments. With heat resistance up to 120°C and resistance to spillages of hot liquids, this screed is ideal for industrial kitchens and similar facilities.

Application Information

Flowfresh HF LT should be applied using a forced action mixer and is suitable for concrete substrates. It is critical to follow the exact mixing ratios and to use the product within the recommended pot life of 10 minutes at 20°C. Substrate and ambient temperatures should not fall below 10°C during application. Ensure adequate ventilation during installation and curing. The system is ready for light traffic in 24 hours, with full chemical cure achieved in 10 days.

Limitations and Restrictions

Flowfresh HF LT should not be applied to polymer-modified screeds or substrates with high moisture content. Ensure that the substrate is free from laitance, dust, and contamination. Do not use this product in areas where temperatures fall below 5°C post-application, or where continuous heat resistance above 50°C is required unless primed with Flowfresh Primer.

Recommended Products

For enhanced performance, use Flowfresh Primer on concrete substrates to increase adhesion and durability. If moisture is present, apply Hydraseal DPM to ensure a secure bond. Consider Flowfresh Quartz for decorative applications where aesthetics are required alongside high-performance flooring solutions.
