Sikaflex 291 Black is a marine-grade polyurethane adhesive sealant in a 310ml cartridge. It provides strong adhesion, flexibility, and vibration resistance in harsh marine environments. Suitable for sealing deck fittings, hull joints, and general marine assembly, it resists saltwater, weathering, and UV exposure. Non-sag for vertical seams and paintable after curing, it bonds to common marine substrates including fibre-reinforced plastics, wood, and metals. Ideal for boats, yachts, and marine repairs. Apply with a standard caulking gun following Sika preparation guidance.
