Nova Flex Metal Roof Sealant is a neutral-cure silicone adhesive designed specifically for metal building applications. Unlike many general-purpose sealants, Nova Flex offers UV resistance, color stability, and is engineered to withstand extreme temperature fluctuations—essential factors for exposed metal roofs. It’s non-corrosive, paintable, and bonds exceptionally well to metals like steel, aluminum, copper, and even Kynar-coated surfaces.Key Benefits and Features - Excellent Adhesion: Bonds firmly with common roof metals and many finishes, reducing the risk of leaks and peels. - Weather-Resistant: Maintains performance in temperatures from -40°F to 400°F and is designed to resist rain, snow, and wind uplift. - Flexible & Durable: Its flexibility allows for natural roof movement without cracking or breaking the bond. - Easy Application: Available in cartridges for standard caulking guns, and shapes readily to seams, flashing, fasteners, and joints. - Color Retention: Fade-resistant, allowing your roof to maintain its intended look for the long haul.Application Best Practices Preparation is key for a lasting seal. Start by cleaning the area to remove all dust, oils, rust, or old sealant residues. For best results, apply Nova Flex on a dry surface in temperatures above freezing. The sealant should be tooled within 10-15 minutes after application for optimal bonding. It typically achieves tack-free status within 30 minutes and full cure in 24 hours, depending on humidity and temperature.Common Uses on Metal Roofs The versatility of Nova Flex Metal Roof Sealant makes it ideal for sealing laps, joints, fasteners, flashing, and even gutter systems.
