Sikaflex 291 310ml Cartridge – Black

Sikaflex 291 Black is a versatile marine-grade polyurethane adhesive and sealant designed for a wide range of sealing, bonding and maintenance applications. Supplied in a 310ml cartridge, it is ideal for boat building, marine repairs and general sealing tasks where a durable, flexible and waterproof seal is required.

Formulated specifically for the marine environment, Sikaflex 291 offers excellent adhesion to common marine materials including fibreglass, timber, aluminium, stainless steel and painted surfaces. Once cured, it forms a strong, elastic seal that withstands vibration, movement, weathering and saltwater exposure, making it suitable for both above and below deck applications.

The black finish provides a clean, professional appearance and is commonly used around deck hardware, hatches, fittings and marine equipment where a darker seal line is preferred.
