Sika Sikaflex® 295 UV - White - 10oz Tube w/Nozzle

The Sika Sikaflex® 295 UV in White is a professional-grade marine sealant and adhesive engineered for the demands of saltwater boating and watercraft maintenance. Whether you're resealing transom joints, bonding hull fittings, or caulking deck hardware after years on the water, this single-component polyurethane formula delivers the durability that separates a weekend repair from a season-long solution.

Sikaflex® 295 UV is formulated with polyurethane technology that cures to a flexible, waterproof bond resistant to constant flexing, vibration, and UV exposure—critical factors for hull seams and topside joints that endure engine vibration and harsh sun. The UV designation means this sealant won't chalk or degrade under extended UV radiation, a real advantage in open-water conditions where unprotected caulk fails within a season.

Anglers and boat owners rely on Sikaflex® 295 UV for cabin sole seams, portlight frames, pulpit bases, and through-hull fitting installations where both waterproofing and structural integrity matter. It adheres tenaciously to fiberglass, aluminum, stainless steel, and wood—the primary materials found in modern fishing boats and cruising vessels—and maintains elasticity even after full cure, accommodating the thermal expansion and structural movement inherent to composite hulls.
