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. ## Frequently Bought Together - Sika – Sikaflex 291i – Marine Sealant and Adhesive – Specifically Designed For The Marine Market – Solvent Free – Black – 300ml Cartridge - ProDec Extra Strong Caulking Gun --- ## 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/54682220-sika-sikaflex-291i-marine-sealant-and-adhesive-specifically-designed-marine](https://www.desertcart.sn/products/54682220-sika-sikaflex-291i-marine-sealant-and-adhesive-specifically-designed-marine) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-08-05*
