3M Marine Adhesive Sealant 5200 Fast Cure is a high-strength, permanent bonding compound designed for above and below waterline applications. This one-component polyurethane sealant creates an extremely strong, waterproof seal that maintains its integrity in the harshest marine environments.

Key Features:

• Fast curing formula becomes tack-free in 1 hour and fully cures in approximately 24 hours
• Retains exceptional strength both above and below the waterline
• Remains flexible after curing to accommodate structural movement and joint flexing
• Excellent resistance to weathering, salt water, and marine chemicals
• Permanent bonding strength for through-hull fittings, deck hardware, and hull-to-deck joints
• White color matches most marine gelcoats and provides a clean finished appearance

Ideal for bonding fiberglass, wood, and metal components in boat construction and repair. The 1 oz tube size is perfect for small jobs and repairs. This is a permanent adhesive sealant—not recommended for parts that may require future disassembly.
