Technical Datasheet Technical data polyurethane prepolymer white, black 1.44 kg/l 5,500 ± 500 mPa-s (at +230C) 750 ± 50% 4.0 N/mm2 80 ± 2 ISOFLEX-PU 510 is a one-component, polyurethane, liquid waterproofing membrane offering: • Mechanical, chemical, thermal, UV and weather resistance properties, as it is based on pure, elastomeric, hydrophobic polyurethane resins. • A continuous, elastic, waterproof, vapor-permeable layer, without seams or joints. • Excellent bonding to various substrates, such as concrete, screeds and most waterproofing layers. • Applicability even to irregular substrates. • An affordable and reliable solution for waterproofing. • Availability in white and other colors. When a dark color of ISOFLEX-PU 510 has been chosen as an exposed layer, it is necessary to cover it with a layer of TOPCOAT-PU 720 of the same color. 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 510 is suitable for waterproofing: • Flat roofs and balconies as an exposed waterproofing membrane. • Under tile layers in kitchens, bathrooms, balconies and flat roofs, as long as quartz sand has been broadcast on its last layer. • Under thermal insulation boards on flat roofs. • In construction works, such as highways, bridge decks, tunnels, etc. • Foundations. • Gypsum and cement boards. • Old layers of bituminous or EPDM membranes. • Polyurethane foam. Metal surfaces.

Reaction to fire: Euroclass F (EN 13501-1) Service temperature: from -300C to +900C 1. Substrate preparation In general, the substrate must be dry (moisture content < 4%), clean, free of grease, loose particles, dust, etc. 1.1 Concrete substrates Any existing cavities in concrete should be filled with the appropriate repairing materials in advance. Severe cracks on the substrate must be primed locally and after 2-3 hours (depending on 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...

b) Local waterproofing of cracks In this case, the primer is applied on the substrate only across the cracks to a width of 10-12 cm. Two-three hours after priming, the first ISOFLEX-PU 510 layer is applied and, while still fresh, a 10 cm wide polyester fleece strip (60 g/m2) is embedded lengthwise. Then, two extra ISOFLEX-PU 510 layers are applied along the cracks, completely covering the reinforcement. Consumption: approximately 200-250 g/m of crack length. c) Waterproofing under tiles ISOFLEX-PU 510 is applied by brush or roller in 2 layers. ISOFLEX-PU 510 should be locally...
