Sika Sikaflex® 295 UV - White - 3oz Tube

The Sika Sikaflex® 295 UV - White - 3oz Tube is a premium marine sealant engineered for serious boaters and anglers who demand long-term waterproofing in harsh saltwater environments. Whether you're resealing gunwales, bonding hardware to fiberglass, or patching cracks in cabin trim, this one-component polyurethane adhesive delivers the durability required to keep your vessel watertight for years. The 3oz tube format offers convenient portability for onboard repairs or pre-launch maintenance without committing to larger quantities.

UV resistance is critical in marine applications where sun exposure accelerates degradation of standard caulks, and Sikaflex® 295 UV resists cracking and chalking that plague inferior products after a single season. The formulation bonds reliably to fiberglass, wood, metal, and rubber—the core materials found on most recreational and fishing boats—while maintaining excellent gap-filling properties even in tight seams. Fast tack-free time means faster turnaround between cure stages, and the sealant's paintable and sandable characteristics allow seamless finishing that blends with existing hull or cabin aesthetics. Salt water resistance ensures the cured bond won't degrade from constant exposure to spray, bilge moisture, or submerged hardware.

Experienced boaters rely on Sikaflex® 295 UV for deck-to-hull transitions, window frame installation, and through-hull fitting seals where failure means potential water intrusion and costly interior damage. The tube's compact size makes it ideal for anglers and cruisers who stock spare sealant in cabin lockers for emergency repairs at the dock or during extended trips. Application works best on clean, dry surfaces; standard polyurethane primers may be needed on porous substrates for maximum bond strength. This industrial-grade sealant outlasts consumer-grade caulks by years when exposed to marine conditions, making it a proven choice for professional boat builders and meticulous owners alike.
