FIELDS OF APPLICATIONISOFLEX-PU 500 is ideal for waterproofing terraces and balconies asan exposed waterproofing membrane. It is also recommended for waterproofingunderneath tile layers in kitchens, bathrooms, balconies and terraces,as long as quartz sand has been broadcasted on its last layer. Suitable as well ISOFLEX PU 500for waterproofing under thermal insulation boards on terraces, for green roofs,flower beds etc. Moreover, it can be applied on gypsum and cement boards,old layers of bituminous or EPDM membranes and polyurethane foam.In construction works, it can be used on highways, bridge decks, tunnels etc. PROPERTIESISOFLEX-PU 500 is a one-component polyurethane, waterproofing liquidmembrane. It has excellent mechanical, chemical, thermal, UV and weatherresistant properties, as it is based on pure elastomeric hydrophobic polyurethaneresins. It forms a continuous, elastic, waterproofing, vapor-permeable sealinglayer, without seams or joints. It offers excellent bonding to various substrates likeconcrete, cement-mortars, wood and to any type of waterproofing membrane.It can also be applied to uneven substrates. TECHNICAL CHARACTERISTICS Cleaning Priming Colors : white, grey, redbrown Density : 1,39 Kg/l Elongation at break : (900±80)% (ASTM D 412) 2 Tensile strength : 6,4 N/mm (ASTM D 412) Hardness according to SHORE A : 75±3 Waterproofing : 7 atm, acc. to DIN 1048 Temperature resistance : from -40 °C to +90 °C SUBSTRATE PREPARATIONThe substrate must be dry, clean, free of grease, loose particles, dust etc.Any existing cavities in concrete should be repaired in advance. Porous surfaces Local sealing Local reinforcementshould be treated with the special primer PRIMER-PU 100, with a consumptionof approx. 200 g/m2. DIRECTIONS FOR USEISOFLEX-PU 500 is applied by brush or roller in two layers. The first layer isapplied 2-3 hours after priming and while PRIMER-PU 100 is still tacky.The second layer should follow crosswise, after 4-24 hours depending onthe weather conditions. In cases of severe or multiple cracks, it is recommendedto reinforce locally or thoroughly ISOFLEX-PU 500 with fiberglass-mesh orpolyester-fiber. CONSUMPTIONApprox. 1,0-2,5 kg/m2, depending on substrate and type of reinforcement. First layer Second layerIn case of application by spraying it may be diluted, depending onthe weather conditions, up to 10% only with the special solvent SM-16. PACKAGINGISOFLEX-PU 500 is supplied in tin buckets of 1 kg, 6 kg and 25 kg.
