Technical Datasheet Description One-component, fast-setting, aliphatic polyurethane, liquid waterproofing membrane for flat roofs: • Based on elastomeric, hydrophobic polyurethane resins of excellent mechanical, chemical, thermal, UV and weather resistance. • Forms a continuous, elastic, waterproof, vapor-permeable layer, without seams or joints. • Features excellent adhesion to various substrates, like concrete, cement screeds, wood and most waterproofing membranes. • Applicable even to irregular substrates. • Does not turn yellowish - on the contrary, it preserves its original color and does not require any additional coating, even if a dark color has been chosen. Certified according to EN 1504-2 and classified as a coating for surface protection of concrete. CE marked. Certificate No.: 2032-CPR-10.11. ISOFLEX-PU 600 is suitable for waterproofing: • Roofs, flat roofs and balconies, as exposed waterproofing membranes. • Gypsum and cement boards. • Old layers of bituminous or EPDM membranes. • Polyurethane foam. • Metal surfaces. polyurethane prepolymer white, grey (at +23°C) 2.

Reaction to fire: Euroclass F 1. Substrate preparation In general, the substrate must be dry (moisture content < 4%) and free of grease, loose particles, dust, etc. 1.1 Concrete surfaces Any existing cavities in concrete should be repaired in advance. Severe cracks must be primed locally and after 2-3 hours (depending the weather conditions) must be sealed with the polyurethane sealants FLEX PU-30 S or FLEX PU-50 S. Concrete and other porous surfaces with moisture content < 4%, should be treated with special primer PRIMER-PU 100, at a consumption of approx. 200 g/m2. Surfaces with moisture...

Then, the remaining content is poured over the polyester fleece and is spread with a roller. Consumption: approximately 2.00-2.25 kg/m2, depending on the substrate. b) Local waterproofing of cracks In this case, the primer is applied on the substrate, only along the cracks to a width of 10-12 cm. Two-three hours after priming, about two thirds of the ISOFLEX-PU 600 container is poured and while this is still fresh, a 10 cm wide polyester fleece strip (60 g/m2) is placed on it and then rolled, to help release the entrapped air. Then, the remaining content is poured over the polyester fleece and...
