Technical Datasheet Description DUROFLOOR-PU is a two-component, colored, aliphatic polyurethane system. After its application, it forms a strong and elastic membrane that shows excellent resistance to UV radiation. It is resistant to abrasion, as well as organic and inorganic acids, alkalis, petroleum products, specific solvents, waste, water, sea water and weather conditions. It is at temperatures ranging from -300C to +1000C in dry loading and up to +600C in wet loading. It is classified as SR-B2,0-AR2-IR8, according to EN 13813. DUROFLOOR-PU is used as a brushable coating on floors that require high elasticity, mechanical and chemical strength. It is suitable for: • Cement-based substrates, e.g. concrete, cement-mortars or asbestos cement. • Steel or iron surfaces. • Existing epoxy floors. • Refrigerator and freezer rooms, industrial areas, warehouses, laboratories, hospitals, wine factories, slaughter-houses, canned food factories, garages, car workshops, etc. It is suitable for interior and exterior applications. Basis: two-component polyurethane resin Colors: RAL 7040 (grey) other colors by special order Viscosity: approx. 1,400 mPa's Mixing ratio (A:B): Pot life: Minimum hardening temperature: Shore D hardness: Walkability: Successive layer: Final strength: Wear resistance (EN 13892-4): Impact resistance (EN ISO 6272): Adhesion: (EN 13892-8) Tensile strength: (ASTM D412) Elongation at break: (ASTM D412) Cleaning of tools: Tools should be cleaned with SM-16 solvent, immediately after use. 1. Substrate preparation The flooring surface should be: • Dry and stable. • Free of materials that prevent bonding, e.g. dust, loose particles, grease, etc. • Protected from underneath moisture penetration. It should also meet the following requirements: a) Cementitious substrates: Concrete quality: at least C20/25 Cement screed quality: cement content 350 kg/m3

Age: at least 28 days Moisture content: less than 4% b) Iron or steel surfaces: Should be free of rust or any corrosion that may prevent bonding. Depending on the nature of the substrate, it should be prepared by brushing, grinding, sandblasting, water blasting, shot blasting, etc. Then, the surface should be cleaned from dust with a high-suction vacuum cleaner. 2. Priming Cementitious surfaces should be primed with the polyurethane primer PRIMER-PU 100 or with the epoxy primers DUROFLOOR-PSF or DUROPRIMER. Consumption: 200-300 g/m2. After the primer has dried, any existing imperfections...
