It offers superior elasticity, corrosion resistance, and water resistance for both fresh and saltwater environments. Easy to apply with standard piston guns, it cures to a paintable, sandable finish within 24 hours, making it ideal for durable, vibration-resistant marine and interior sealing applications. ## Description If you need a marine-grade sealant that creates a strong, secure bond with a wide array of surfaces commonly found in marine applications, Sikaflex-291 LOT's black sealant is the ideal choice. It's specially designed for use where a long working time is needed, and cooler temperatures can extend the curing period. The typical skinning period is four hours, after which it can be painted for a more professional finish. Sikaflex-291 LOT is a self-leveling marine grade sealant, so you won't need to tool it down for an even surface. 10.1 fl. oz. cartridges fit conveniently on a variety of piston guns. Review: Good adhesive for a boating project - I used this to attach a heavy duty rub rail on my old BW Outrage (belt and suspenders approach, I didn't trust that the screws that came with the rub rail would work). It's been six months since I did the work and it seems to be holding well. Cures somewhat quickly which makes it tricky to use on a large area in summer heat. I'd use it again before the #M product. Review: Easy to apply, looks like a good seal - I used it to seal between the body and the bottom pan of a 1970s VW Beetle I'm rebuilding. It'll take me months to find if the seal provided by this product is durable. But for now, it looks encouraging. Also, it is rated for "below the waterline", and that should be more than sufficient overkill for a Volkswagen. As I had to apply the sealant from below the car, it dripped a little bit but not badly. The product flows into place readily and can be smoothed, like caulk, with a gloved (!!!) finger. Go without gloves and have a very messy clean-up coming. The product dries to a deep glossy black. As it is paintable, I plan to spray the bottom of the car with undercoating for protection. The seals cured overnight and look confidence-inspiring. ## Features - IDEAL FOR MARINE APPLICATIONS — Sika 291 adheres to material commonly used in marine construction, such as wood, fiberglass, metal, and metal primers and paint coatings.

Is it elastic or hard like epoxy when cured?** A: It is elastomeric and should work well for that I would think. I used it to seal the roof seams on a 2015 GMC pickup and it worked great. Keep in mind it is self leveling so it spreads out a bit on its own. **Q: Would this work for adhering rubber matting to a wooden and aluminum boat deck?** A: yes, it would work. A permanent solution would be 3M 5200 sealant. Try a small piece first! **Q: can i use this to attach solar panels to camper roof? pnls weigh 24pnds.** A: I used mine for water proofing sealant while glueing down a metal flang which weighed very little. Not sure about the solar panels **Q: Would this work in a swimming pool. I have a concrete pool that has plexiglass windows in the sides below the water level.** A: I believe so, we use it on the seams of our water slide that's underwater at all times. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good adhesive for a boating project *by A***R on January 30, 2026* I used this to attach a heavy duty rub rail on my old BW Outrage (belt and suspenders approach, I didn't trust that the screws that came with the rub rail would work).
