Use Silcor 580 Polyurethane Waterproofing Membrane for: Heavy-duty waterproofing in high-traffic and demanding environments, including stadiums, car parks, and wet areas.
Silcor 580 is a premium-grade, two-part polyurethane membrane designed for long-life waterproof protection. With its very low VOC content and exceptional physical properties, including high elongation and tensile strength, it provides a seamless and durable barrier. This membrane is ideal for applications requiring robust waterproofing, such as stadiums, car park decks, and balconies. Its ability to accommodate structural movements and bridge non-structural cracks ensures long-term performance. When paired with the correct silcor top coat, the product is suitable for heavy traffic areas. The polyurethane chemistry ensures it is free from bitumen or tar, preventing bleeding or staining.
Primer Information: Use Silcor Primer BS for dry concrete and metals, or Epocote F100W for damp concrete. Proper priming is essential for optimal adhesion and performance.
Cure Time: Tack-free in 4 hours, minimum recoat time of 15 hours, and ready for flood testing in 15 hours. Cure times vary with temperature and humidity.
Application: Apply using a notched trowel, squeegee, roller, or brush. Ensure proper mixing and application to achieve the specified dry film thickness (DFT). It is important to remember that this product is semi self leveling, and should only be applied to horizontal surfaces set to falls.
Chemical Properties: High solids, 2-part polyurethane with excellent resistance to water, detergents, and chemicals. This makes it suitable for demanding environments like laboratories and plant rooms.
