Flowdur HF - Heavy Duty Polyurethane Screed
Vendor: Virtus Resins
HF is a heavy duty, trowel applied polyurethane floor screed for use on concrete and polymer modified screeds. It's designed with the highest order of durability, impact, abrasion and chemical resistance. It's lightly textures finish makes the product ideal for both wet and dry processing environments such as the food, beverage and chemical industries.
Advantages
- Stable to steam cleaning and hot water exposure at a thickness of 9mm.
- Very high chemical resistance
- Non-tainting
- Seamless
- High abrasion resistance
- Slip resistant.
Components in the System
- Resin
- Hardener
- Graded Silica Aggregate
Surface Preparation
Inadequate preparation will lead to loss of adhesion and failure. Grinding, light vacuum-contained shot-blasting or planing is recommended. Percussive scabbling or acid etching is not recommended. Anchorage grooves should be cut to a width and depth of twice the thickness of the floor finish at the edges, bay joints, up-stands, drains, doorways and at regular points across the floor, and all debris removed.
Resistant to: Flowdur HF is resistant to a wide range of commonly used chemicals in the food, dairy and pharmaceutical industries such as concentrated citric acid (fruits), spirit vinegar (50% acetic acid), lactic acid (food & dairy products) and common alcohols (methanol & ethanol). Flowdur HF is also resistant to a wide range of inorganic acids, fuels, hydraulic oils, mineral oils and solvents.
Coverage
12 kg/m² at 6 mm or 18 kg/m² at 9mm
Drying Time
At 20 degrees, cure time to light pedestrian traffic is 12 hours, light wheeled traffic is 24 hours and heavy duty traffic is 48 hours.
Cleaning & Maintenance
Regular cleaning is essential to enhance and maintain the life expectancy, slip resistance and appearance of the floor. Flowdur HF can be easily cleaned using industry standard cleaning chemicals and techniques. Consult your cleaning chemical and equipment supplier for more information. When applied at 9mm thickness, Flowdur HF is fully steam cleanable.
Thickness
6mm or 9mm
Primer
Priming should be carried out using Flowdur Primer or Flowprime DPM (where moisture levels exceed 65%).
Mixing:
Prior to mixing, the temperature of the three components must be between 15 and 25 ºC. Pre-mix the coloured resin component before use. Add the hardener component to the coloured resin component and mix using a low speed electric mixer (300 - 400 rpm) for 1 - 2 minutes until homogeneous. Decant the mixture into a rotary drum mixer and add the aggregate component in stages, mixing for a minimum of 3 minutes until a uniform coloured, lump-free mix is obtained.
Application:
Apply to primed areas to the required thickness using a steel float. Ensure that anchor grooves are fully wetted out with material. The cured product should be protected from other trades using Kraft paper or similar breathable material. Polythene should not be used. Protect the installed floor from damp, condensation and water for at least 4 days.
