It has excellent adhesion to most commonly used roof substrates such as concrete, asphalt membranes, cement tiles, acrylic, polyurethane paints etc. Shows very low water uptake and crack bridging ability.
Its innovative formula offers fast surface hardness, no tack surface, low dirt pick up, able to keep reflectance properties for longer time. Exhibits high resistance to weather conditions from -30°C/+90°C and excellent resistance to UV radiation and thermal ageing.
Certified by the University of Athens, Department of Physics, as a cool thermoreflective roof coating is a top layer of high reflectivity (visible spectrum reflectance 93%) which improves energy efficiency by reducing cooling costs. Easy application, safe use and no restrictions makes HyRoof Hybrid PU ideal solution for DIY application.
• Hybrid elastomeric polyurethane
• It forms a highly elastic, seamless membrane
• Excellent protection from moisture and standing water up to 10 years
Certified from the University of Athens, Department of Physics, as a cool material for roofs with the following properties:
Initial Total Solar Reflectance SR = 88% (300-2500nm) (ASTM 903-96 and ASTM G 159-98)
Solar Reflectance Visual SRvis = 93% (ASTM E 903-96 και ASTM G 159-98)
Solar Reflectance Near Infrared SRnir = 89% (ASTM E 903-96 και ASTM G 159-98)
Infrared Emittance Factor ε = 0,87 (ASTM E 408-71-2002)
Solar Reflectance Index SRI = 111 (ASTM E 1980-01)
Available in white.
Surfaces should be smooth, clean and dry, free from grease, dust, loose or flaking material. Cracks or joints should first be filled with Elastomeric Putty by Vitex.
New or weathered surfaces should be primed with Hyroof Primer for the stabilization of the substrate.
Stir well before use. Applied with roller, emulsion brush or spay gun in two layers crosswise without dilution, with a total consumption of at least 1 Lt/m² all over the flat surface and on perimeter vertical parapets at least 30-40 cm in height. For protection and increase the lifetime of the waterproofing more than 10 years is required to use a polyester fabric 50-100 gr/m² as a reinforcing material which is incorporated between the layers while the underlying surface is still wet. Recommended consumption of HyRoof Hybrid PU is 1,1 Lt/m² under reinforcement, topcoat 0,8Lt/m², reaching a total consumption of at least 1,9 Lt/m².
Do not apply at temperature below 5°C, above 35°C and/or relative humidity above 70%.
Avoid application when rain or frost is expected in the next 48 hours.
It is touch-dry after 2-3 hours and can be recoated after 16 to 24 hours. Drying time depends on weather conditions (humidity and temperature).
Tools must be cleaned immediately after use with water and if needed with soapy water or a detergent.
