ISOFLEX is an elastomeric, waterborne, liquid waterproofing membrane for flat roofs. Hasexcellent bonding to various substrates, such as concrete, wood, metal and any type ofwaterproofing membranes and is applicable even to irregular substrates. After curing, it forms acontinuous, elastic, waterproof and vaporpermeable membrane, without seams or joints, offering: High elasticity. High resistance to weather and aging. High whiteness and solar reflectance. Improvement of building energy efficiency bydecreasing the roof temperature.Certified according to EN 1504-2 and classified asa coating for surface protection of concrete. CE marked. Certificate No.: 2032-CPR-10.11.Fields of applicationISOFLEX is ideal for waterproofing flat roofs, curved roofs, etc. Constitutes a simple and safesolution for waterproofing roof details, such as corners, edges and joints between differentadjacent materials, as well as isolated cracks. Furthermore, thanks to its high solar reflectance, itcan be used as cool roof paint.Colors: white, red-brownHardness according to SHORE A: 50Density: 1.41 kg/l ± 0.02 kg/lElongation at break: 600 ± 50% (EN ISO 527)Capillary absorption: 0.01 kg/m2 ·h 0.5(EN 1062-3, requirement of EN 1504-2: w < 0.1)Permeability to CO2: Sd > 50 m(EN 1062-6)Water vaporpermeability: Sd=0.80 m (permeable)(EN ISO 7783-2, Class I < 5m)Adhesion: 1.3 N/mm2(EN 1542, requirement forflexible systems with no traffic: 0.8 N/mm2)Artificial weathering: Pass (no blistering, cracking or flaking)(EN 1062-11, after 2000 h) Reaction to fire: Euroclass F(EN 13501-1)Solar reflectance: 90%(ISOFLEX white)(ASTM E903-96)Infrared thermal emmitance: ε = 0.86(ISOFLEX white)(ASTM E408-71)Minimum application temperature: +5°CService temperature: from -15°C to +90°CViscosity: ~ 80,000 mPa·sDrying time at +200C: 3 h (touch dry)(EN ISO 2811-1)Recoat time at +200C: 24 h (touch dry)(EN ISO 2811-1)Directions for use1. Substrate preparationThe substrate must be dry, clean, free of grease,loose particles, dust, etc. Any existing cavities inconcrete should be filled in advance. The substratecan be primed with the special primer ISOPRIMER with a consumption of approx. 200 g/m2.2. Applicationa) Full-surface waterproofingISOFLEX is applied by brush or roller in two layers,after the primer has dried. The second layer shouldbe applied crosswise after the first one has dried.In areas with severe cracks, it is recommended toreinforce ISOFLEX with a 10 cm wide strip of fiberglass mesh (65 g/m2) or polyester fleece (30g/m2) along the cracks. In that case, after theprimer has dried, the first layer of ISOFLEX is applied along the cracks and, while still fresh, the 10 cm wide strip of fiberglass mesh or polyesterfleece is embedded lengthwiseSubsequently, two extra layers of ISOFLEX are applied over the entire surface.Consumption: approx. 1.5 kg/m2, depending on the substrate.In case of dense, multiple cracks appearing all over the surface, it is strongly recommended tofully reinforce ISOFLEX membrane with 100cm wide strips of fiberglass mesh (65 g/m2) or polyester fleece (30 g/m2). These placed stripsmust overlap by 5-10cm.After the primer has dried, a first layer of ISOFLEX is applied to a width of 100 cm (as wide as theupcoming reinforcement), and, while still fresh, a strip of fiberglass mesh or polyester fleece isembedded. The same application process is followed until the remaining surface is covered.Subsequently, two extra layers of ISOFLEX are applied over the entire surface.Consumption: approximately 2.0-2.5 kg/m2, depending on the substrate and the type ofreinforcement.b) Local waterproofing of cracks In this case, the primer is applied on the substrateonly along the cracks to a width of 10-12 cm. After the primer has dried, the first ISOFLEX layer isapplied and, while still fresh, a 10 cm wide strip of fiberglass mesh (65 g/m2) or polyester fleece(30 g/m2) is embedded lengthwise. Subsequently, two extra ISOFLEX layers areapplied along the cracks, completely covering the reinforcement.Consumption: approximately 200-250 g/m of crack length.Tools should be cleaned with water, while ISOFLEX is still fresh.Shelf life – Storage24 months from production date if stored inoriginal, unopened packaging at temperaturesbetween +5°C and +35°C.
