It features low odor and low VOC emissions, making it an eco-friendly, professional-grade solution ideal for demanding waterproof sealing applications. ## Description Resistant to fresh and salt water, as well as the strict requirements of various marine standards, Sikaflex-291i is the perfect sealant for the marine sector. Its high adhesion and elasticity make it the ideal sealant for particularly stressed joints in maritime environments. At the same time, the elastic property ensures that the joints are vibration resistant. Thanks to its unique polyurethane-based formula, the adhesive cures by humidity - at higher temperatures, this process is slightly faster, but slightly slower at lower temperatures. ## Features - Adhesive strength: Sikaflex-291i has an excellent adhesion spectrum and can be used on various surfaces such as wood, metal, ceramic, glass and plastic - Elasticity - This strong adhesive sealant is highly elastic and therefore ideal for applications where a certain mobility is required, such as the grouting of windows or doors - Paintable - This marine adhesive can be painted over after curing. This is especially advantageous for visible joints, which are to be painted later - For marine areas - Resistant to fresh and salt water, this marine sealant is versatile and suitable for sealing on boats and ships - Low emission - This sealant is an environmentally friendly choice. The isocyanate and emission values are low, so the adhesive contains only minimally volatile organic compounds ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00TZNOTUU | | Best Sellers Rank | #16,606 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #19 in Waterproofers | | Brand Name | SIKA | | Color | steel grey | | Compatible Material | Glass | | Customer Reviews | 4.6 4.6 out of 5 stars (159) | | Global Trade Identification Number | 07612894817812 | | Included Components | 1 cartridge | | Item Dimensions | 48 x 48 x 230 millimeters | | Item Form | Liquid | | Item Type Name | Adhesive and sealant | | Item Weight | 0.41 Kilograms | | Manufacturer | Sika | | Material Type | Wood | | Model | 409331 | | Number of Items | 1 | | Part Number | 409331 | | Style Name | Cartridge | | Unit Count | 300 Milliliters | | Water Resistance Level | Waterproof | ## Product Details - **Brand:** SIKA - **Item dimensions L x W x H:** 48 x 48 x 230 millimeters - **Item weight:** 0.41 Kilograms - **Material:** Wood - **Style:** Cartridge ## Images ![Sealant - Sikaflex-291i Steel Grey - Ideal for Marine Use - Highly Elastic and Paintable - Low Odour - 300ml - Image 1](https://m.media-amazon.com/images/I/61HEF2AEOoL.jpg) ## Frequently Bought Together - Colle-Mastic Multipurpose Special Navy, 409331 - Sika – Sikaflex 291i – Marine Sealant and Adhesive – Specifically Designed For The Marine Market – Solvent Free – Black – 300ml Cartridge - Sika Sikaflex -292i – Multipurpose Adhesive – For Marine Applications – Paintable – Solvent-Free – Wheelmark Approved – White – 300ml --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/691428109-sealant-sikaflex-291i-steel-grey-ideal-for-marine-use-highly](https://www.desertcart.hr/products/691428109-sealant-sikaflex-291i-steel-grey-ideal-for-marine-use-highly) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-14*
