ResDev Pumadur HF

ResDev Pumadur HF is a heavy duty, trowel applied polyurethane floor screed for use on concrete and polymer modified cementitious screeds.

Best Uses

ResDev Pumadur HF is designed with the highest order of durability, impact, abrasion and chemical resistance. Its lightly textured finish makes the product ideal for both wet and dry processing environments such as the food, beverage and chemical industries.

Seamless, matt surface with a light slip resistant texture. ResDev Pumadur HF contains a white aggregate which imparts a slip resistant profile to the finished floor.

• Stable to steam cleaning and hot water exposure at a thickness of 9.0 mm
• Very high chemical resistance
• Non-tainting
• Seamless
• High abrasion resistance
• Slip resistant
• FeRFA Type 8 BS 8204-6

ResDev Pumadur 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).

ResDev Pumadur HF is also resistant to a wide range of inorganic acids, fuels, hydraulic oils, mineral oils and solvents. Good housekeeping practices should be employed. Please consult our Technical Department for further advice.

Application

The surface must be clean, dry and free of all contamination. The concrete substrate must have a minimum tensile strength of 1.5 N/mm2. 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. Refer to the Resdev Guide to Surface Preparation for further information.

Pumadur HF can be applied to 7-day old concrete which is visibly dry and having a minimum tensile strength (pull-off) of 1.5 MPa. All the usual stringent surface preparation techniques should be employed. For concrete bases in contact with the ground, a damp-proof membrane should have been incorporated into the slab design, in accordance with the requirements of CP102 (Code of Practice for Protection of Buildings Against Water from the Ground).

Prior to mixing, the temperature of the three components must be between 15 and 25°C. 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. Apply 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.
