Resins and repair kits

Sikaflex-591 – a multi-purpose marine sealant (white, 300 ml) based on Silane Terminated Polymer (STP) technology. Provides elastic, vibration-resistant bonding and sealing for boatbuilding. Features:

• Versatile use: For interior and exterior seams and seals – deck hardware, hatches, rails, hull seams
• Excellent adhesion: Bonds to wood, metals (incl. aluminum), primed surfaces, fiberglass, ceramic, plastics – often without primer
• Durable & safe: Free of isocyanates, solvents, tin, and phthalates; resistant to UV, salt water, and weathering (won’t yellow or crack)
• Flexible & vibration-proof: Cures to a flexible elastomer that absorbs vibrations, expansion, and shocks – ideal for marine conditions

"4-in-1" high-resistance two-component white gelcoat (Osculati) that acts as both filler and finish coat to restore damaged gelcoat surfaces.

• Combines filler and gelcoat in one – applied with a spatula like putty and cures to a glossy white finish.
• Restores the original smooth surface on chipped, scratched, or dented gelcoat areas.
• Provides a bright white coating that blends repairs seamlessly with the surrounding surface.
• Suitable for hull, deck, and other fiberglass component repairs above and below the waterline.
• Once fully cured, it can be painted over or left as the final coat with an integrated wax for shine.
