Sikaflex 291 310ml Ctg White
Sikaflex 291 310ml Cartridge – White
Sikaflex 291 White is a premium marine-grade polyurethane adhesive and sealant designed for sealing, bonding and maintenance applications in harsh marine and outdoor environments. Supplied in a 310ml cartridge, it provides a durable, flexible and waterproof seal for a wide range of marine construction, repair and maintenance tasks.
Developed specifically for marine use, Sikaflex 291 offers excellent adhesion to fibreglass, timber, aluminium, stainless steel and many painted surfaces. Once cured, it forms a tough, elastic seal that withstands vibration, movement, weather exposure and saltwater conditions, helping to maintain watertight integrity and long-term performance.
The white finish is ideal for boats, caravans and recreational vehicles, blending neatly with white gelcoat, painted surfaces and marine fittings for a clean, professional appearance.
