Key Benefits:

• Permanently Flexible Seal: Formulated with a one-part polysulfide base, it cures to a firm, flexible rubber that accommodates structural movement, ensuring a durable, watertight barrier in all marine conditions.
• Versatile Application: Suitable for use both above and below the waterline, making it ideal for bedding deck and hull hardware, sealing thru-hull fittings, and repairing underwater seams.
• Exceptional Chemical Resistance: Offers excellent resistance to teak oils, gasoline, diesel fuel, oil, brine, and most chemicals, ensuring the integrity of your seal even in challenging environments.
• Superior Adhesion: Bonds reliably to a wide range of marine substrates including fiberglass, wood, metal, and glass, forming a secure and lasting waterproof bond.
• Non-Shrinking Formula: Maintains its volume and consistency after application, providing effective, consistent coverage without compromising the seal over time.
• Sandable and Paintable: After complete curing (10-20 days), the sealant can be sanded and painted to achieve a smooth, professional finish that integrates seamlessly with your vessel's aesthetics.
• Rapid Tack-Free Time: Becomes tack-free within 1 to 3 days (or 24 hours at 75°F, 50% RH), allowing for quicker progress on your marine projects.
• Emergency Repair Capability: Can be applied to damp surfaces and even underwater for quick, essential emergency repairs, providing critical flexibility when needed.

Compatibility & Usage:

• Bonds To: Fiberglass, wood, metal, glass, and itself. (No priming required except on oily woods such as teak.)
• Not Recommended For: Use with ABS or Lexan plastics.
• Paint Compatibility Note: Not compatible with all paints, including Sikkens, Cetol, and Deks Olje. Test a small area of the caulking after curing for paint compatibility; a latex primer may be used if paint does not dry in a reasonable amount of time.
