Trusted by professionals and OEMs, it delivers a durable, smooth finish that stands up to the rigors of marine environments. ## Description Sikaflex 291 Fast Cure MarineAdhesive and Sealant - Sikaflex 291 is a 1-component marine grade polyurethane elastomer adhesive and sealant. Used by many boat builders and fast cure times make it ideal for applications where speed is important. Review: Used this to fill the seam between the hull and deck. Used an electric calking gun allowing for controlled flow into the seams which were 22ft runs from stern to bow. took two tubes of Silkaflex. While fresh it was easy to use a scraper to push this material deeper into the seam and simple to remove excess leaving a smooth seam level with the deck. It took several days to harden to my satisfaction and in the meantime collected a layer of dust onto its surface. Once painted there is a subtle but clear discoloration showing through the paint. It's a good product but as this was a restoration job on a classic wooden boat I think epoxy would have been a better choice. But, no complaints with how this material works and I'm sure it will hold up for some time as the hull and deck flex a bit with movement and with the natural swelling and shrinking inherent in wood. Review: This is really good RTV! I didn't know Silksflex existed until I had to change out a pair of jet drives on a Zodiac Hurricane. Silksflex RTV was the recommended by the OEM manufacturer. I use Silkaflex on Motorhomes, trucks and around my house. Very strong and flexible and seawater resistant. ## Features - Components are one piece, moisture-curing polyurethane adhesive ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01GPIXX5Y | | Amazon Bestseller | #476,647 in Automotive ( See Top 100 in Automotive ) #294 in Boat Maintenance Supplies | | Brand Name | SIKA | | Color | white | | Compatible Material | Metal | | Container Type | Cartridge | | Customer Reviews | 4.4 4.4 out of 5 stars (625) | | Included Components | 10 fluid ounce cartridge | | Item Form | Gel | | Item Package Quantity | 1 | | Item Type Name | Adhesive | | Item Weight | 300 Grams | | Manufacturer | Sika Corporation | | Material Type | 該当なし | | Model | 90919 | | Other Special Features of the Product | Fast Drying | | Specific Uses For Product | Boating | | UPC | 033886005258 | | Unit Count | 10.1 Count | | Viscosity | Moderate | | Volume | 10.1 Fluid Ounces | | Water Resistance Level | Water Resistant | ## Product Details - **Brand:** SIKA - **Item Form:** Gel - **Material:** 該当なし - **Special Feature:** Fast Drying - **Specific Uses For Product:** Boating ## Images ![Sikaflex 291 Fast Cure White 10.3 Oz. 300 Ml - Image 1](https://m.media-amazon.com/images/I/71EkVlxGSIL.jpg) ## Questions & Answers **Q: Does the black caulk dry to a gloss, or is it more matte finish, like a dull rubber?** A: it still retains a dark matte color I would not say dull, but not a gloss finish **Q: Will it bond to bare aluminum to seal around the rivets?** A: Yes, I used it to seal my roof fans on my Sprinter. It adhered to painted metal (scored the paint), wood framing of the opening, plastic shroud and aluminum pressure plates. I am extremely satisfied with this product and from the day installed, it shows no wear even after a year. Excellent product... Another really good product is 3m 4200 Marine Adhesive... **Q: Will this bond to rubber?** A: Not sure about rubber, but everything else I happened to get it on and let dry it stuck like paint. My clothes, stainless railings, fiberglass cabin, teak of course, cork fishing rod handle, my leather wallet. . . **Q: can you use to adhere spoiler** A: probably work great ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by J***F on July 21, 2024* Used this to fill the seam between the hull and deck.
