Bostik Marine Silicone Sealant 280ml – Heavy-Duty Waterproof Sealant for Boats

Strong Sealing for Marine Conditions

The Bostik Marine Silicone Sealant 280ml provides a heavy-duty solution for sealing joints and gaps in marine and outdoor environments. Because it is formulated to resist saltwater, weather, and UV light, it offers dependable protection where ordinary sealants fail.

Durable, Flexible and Watertight

This marine-grade silicone cures into a flexible joint that moves with surfaces, preventing cracks or separation. As a result, it creates a watertight barrier that protects boats and outdoor equipment against leaks and corrosion. Its durability ensures long-lasting performance in even the toughest conditions.

Easy Application for Large Projects

Packaged in a standard 280ml cartridge, the sealant works with most caulking guns for smooth application. It bonds strongly to glass, aluminium, fibreglass, painted surfaces, and most non-porous materials. Since it resists sagging, you can apply it neatly to both vertical and horizontal joints.

Suitable for Boats and Outdoor Repairs

Bostik Marine Silicone is ideal for sealing hatches, portholes, windows, joints, and deck fittings. It is also suitable for caravans, trailers, and outdoor structures where water resistance is vital. Therefore, it is a must-have product for boat owners, contractors, and DIY enthusiasts.

Conclusion

For long-lasting protection against saltwater, leaks, and weather, choose the Bostik Marine Silicone Sealant 280ml. Strong, flexible, and easy to apply, it delivers professional sealing performance for marine and outdoor use.
