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 ### ⭐⭐⭐⭐⭐ This is worth every penny *by G***T on August 28, 2026* Best stuff for outdoor applications ### ⭐⭐⭐⭐⭐ Excelente artículo, lo volvería a comprar *by O***O on July 29, 2026* Muy bueno, aunque debe saber que demora unas 48 horas para que seque bien y más si es muy grande el grosor que aplicó pero calidad extrema ### ⭐⭐⭐⭐⭐ White Caulk for the win *by J***T on June 15, 2026* Best caulk I’ve ever had the pleasure to work with. Filled the cracks like none other. You know, I was debating the Black Caulk, because I thought it might be more filling, but the white Marine Caulk, was enough to get the job done. ## Frequently Bought Together - Sika Sikaflex-291 LOT - General All-Purpose Adhesive and sealant, Black - Marine Use - Elastic and Non-Corrosive - 10.1 fl. oz. - Sikaflex-291, Black, General All-Purpose Fast Cure Marine Adhesive and sealant.
