Repair roof leaks with Karnak 502MS Karna-Flex, a flexible rubberised thermoplastic sealant designed for long-lasting waterproof protection. Suitable for metal, concrete, plywood, asphalt, modified bitumen and spray polyurethane foam roofs, it forms a durable, weather-resistant membrane. Its strong adhesion allows application to wet or dry surfaces, even underwater, while maintaining flexibility in cold temperatures.
Supplied in a 10.5-litre tub, this single-component sealant has a smooth, buttery consistency for easy brush or trowel application. Ideal for sealing rooflights, gutters, downpipes, metal fasteners and damaged seams, it provides reliable protection against water ingress. PVC and TPO membranes must be weathered for at least four years before application.
