Thank you! Review: OK for what I used it for. - I think this did the job, resealing the vapour membrane on BMW doo before refitting the door card. It's NOT an instant grab adhesive but seems to have worked. I left it to cure for 3 days before I fit the card. Only use if ambient temperature is greater than 10c for a few days. ## Features - May cause an allergic skin reaction. - SPECIFICALLY DESIGNED FOR THE MARINE MARKET – Highly flexible adhesive and sealant suited for most internal boat sealing applications. - MULTIPURPOSE – Use it as a sealant or adhesive on wood, metal, ceramics, plastics and more for high grab adhesion and seals. - HIGHLY ELASTIC – This moisture-curing, non-sag 1-component polyurethane sealant and adhesive is highly flexible and works well in areas prone to strong vibrations. - PROVIDES PROFESSIONAL-GRADE RESISTANCE – Resistant to fresh water, sea water, limewater, sewage effluent diluted acids and much more providing suitability for repairs and maintenance on boats and marine vehicles. - MULTIPLE COLOURS AVAILABLE – Choose from black, white or grey to suit your space, or over-paint it when dry. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00UN3UNL0 | | Best Sellers Rank | 3,061 in DIY & Tools ( See Top 100 in DIY & Tools ) 62 in Sealers | | Brand | Sika | | Colour | Black | | Compatible Material | Metal, Wood, Plastic, Frame | | Container Type | Tube | | Country Of Origin | Switzerland | | Customer Reviews | 4.4 out of 5 stars 150 Reviews | | Full Cure Time | 48 Hours | | Included Components | 1x Cartridge | | Item Form | Paste | | Item Package Quantity | 1 | | Item Type Name | Sealant and Adhesive | | Item Volume | 70 Millilitres | | Item Weight | 0.1 Grams | | Item form | Paste | | Item package quantity | 1 | | Manufacturer | Sika Everbuild | | Manufacturer Part Number | 9091567 | | Material | Polyurethane | | Model Number | 291i | | Other Special Features of the Product | Marine-Specific Resistance and High Elasticity | | Special feature | Marine-Specific Resistance and High Elasticity | | Unit Count | 70.0 millilitre | | Viscosity Level | High | | Water Resistance Level | Water Resistant | ## Product Details - **Brand:** Sika - **Colour:** Black - **Item form:** Paste - **Material:** Polyurethane - **Special feature:** Marine-Specific Resistance and High Elasticity ## Images ![Sika Sikaflex 291i Marine Sealant and Adhesive, Black, 70ml Mini Cartridge - Image 1](https://m.media-amazon.com/images/I/51oisHrs4-L.jpg) ![Sika Sikaflex 291i Marine Sealant and Adhesive, Black, 70ml Mini Cartridge - Image 2](https://m.media-amazon.com/images/I/71FYOh4bGOL.jpg) ![Sika Sikaflex 291i Marine Sealant and Adhesive, Black, 70ml Mini Cartridge - Image 3](https://m.media-amazon.com/images/I/71+U9ClbgxL.jpg) ![Sika Sikaflex 291i Marine Sealant and Adhesive, Black, 70ml Mini Cartridge - Image 4](https://m.media-amazon.com/images/I/71Vn5q2Q7EL.jpg) ![Sika Sikaflex 291i Marine Sealant and Adhesive, Black, 70ml Mini Cartridge - Image 5](https://m.media-amazon.com/images/I/81soYBuq2vL.jpg) ## Available Options This product comes in different **Color, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Super quality *by R***D on 15 July 2025* I don't know how they managed to do it extra super quality but they really did it. Used it on cracks, perfect solution. Thank you! ### ⭐⭐⭐⭐ OK for what I used it for. *by M***T on 14 March 2026* I think this did the job, resealing the vapour membrane on BMW doo before refitting the door card. It's NOT an instant grab adhesive but seems to have worked. I left it to cure for 3 days before I fit the card. Only use if ambient temperature is greater than 10c for a few days. ### ⭐⭐⭐⭐⭐ Perfect *by T***Y on 22 October 2021* I used this while fitting a fish finder transducer to the transom of my little rib and it works a treat to seal up the holes and stop water ingress into the wood. Its great stuff, expensive but worth it. Having seen a few people who use bathroom silicone on their boats and then seen how the boats ended up getting damage over a short period, I would strongly recommend not being cheap and getting the proper stuff which this sikaflex is. ## Frequently Bought Together - Sika – Sikaflex 291i – Marine Sealant and Adhesive – Specifically Designed For The Marine Market – Solvent Free – White – 70ml Mini Cartridge - WELLOCKS Assorted Self Tapping Screws | 265 PCS M3/M4/M5 Stainless Steel Screws Assortment Kit | Phillips Flat Head Countersunk Wood Screw Set with Storage Box | for Homemade Repairment Woodwork(D034) --- ## 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.sn/products/47904797-sika-sikaflex-291i-marine-sealant-and-adhesive-black-70ml-mini](https://www.desertcart.sn/products/47904797-sika-sikaflex-291i-marine-sealant-and-adhesive-black-70ml-mini) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-09-28*
