Sika Sikaflex® 295 UV - Black - 3oz Tube

The Sika Sikaflex® 295 UV - Black - 3oz Tube is a premium marine sealant purpose-built for the demands of saltwater boating and fishing applications. Whether you're sealing transom cracks, bonding trim, or waterproofing through-hull fittings on a center console or offshore vessel, this polyurethane-based adhesive delivers the durability that separates a solid repair from one that fails mid-season. Anglers and boaters operating in harsh marine environments know that UV exposure, salt spray, and thermal cycling will destroy inferior sealants—Sikaflex 295 UV resists all three.

This 3oz tube formulation features UV-resistant chemistry that prevents cracking and chalking—critical when deck hardware, rail bases, and hatch frames sit exposed to direct sunlight for months. The gap-filling properties allow you to work with imperfect surfaces, a real advantage when bonding corroded aluminum or aged fiberglass that won't sand perfectly smooth. Fast tack-free time means you can position components and move on to the next task without clamping gear for hours, while the paintable and sandable finish lets you integrate repairs seamlessly into existing topside work. Salt water resistance ensures the bond remains intact even when seawater wicks beneath the surface.

Professional boat repair technicians and experienced DIY anglers rely on Sikaflex 295 UV for transom sealing, rubbing strake attachment, electronics housing, and structural bonding where adhesive durability directly impacts safety and resale value. The black color matches most modern boat finishes, reducing the need for post-cure painting. Apply this sealant to clean, dry surfaces using standard caulking guns; the tube size makes it economical for spot repairs while providing enough material for moderate deck projects. For optimal results on saltwater vessels, ensure surfaces are free of salt residue and oils before application.
