Sikaflex 291 Marine Adhesive / Sealant – White, 70 ml Mini Sausage
Sikaflex 291 is a one-component, moisture-curing polyurethane adhesive and sealant engineered for demanding marine environments. The 70 ml mini sausage format is ideal for precision application in tight spaces — delivering a fast-curing, flexible, watertight bond that holds up to vibration, UV exposure, and constant moisture.
Formulated with low viscosity and medium modulus, it flows smoothly into joints and gaps, then cures to a durable, paintable seal that won't crack or shrink over time.
Compatible Applications
- Deck hardware installation (cleats, hatches, fittings)
- Through-hull fittings and port sealing
- Cabin windows and portlights
- General above-waterline sealing and bonding
- Teak and non-skid deck seams
Key Features
- One-component — no mixing required
- Fast cure, moisture-activated
- Low viscosity for easy application in confined areas
- Medium modulus — flexible yet strong
- Paintable after cure
- Resistant to UV, saltwater, and fuel splash

Parts Desk Insights
The 70 ml mini sausage is the go-to choice for single-use or small-area jobs where a full cartridge would go to waste. Best suited for deck hardware installs, portlight reseals, and fitting touch-ups where precision matters more than volume. For larger sealing runs — such as full deck seam work or multiple fittings — consider the 11 oz. cartridge format. Pair with Sikaflex 205 Primer on porous or difficult substrates for maximum adhesion.
