Is there not a plate with the dish that you could fix on permanently so that you could easily remove the dish? **Q: Dear, May i know the best before date?** A: Morning. Exp Date of current stock is 09/2023. Hope that helps. **Q: Can I use this to seal a roof vent on my camper? I need to make sure it is completely watertight. Thank you** A: Yes , you can , and it will seal against water ingress, It's also used for sealing deck fittings on a yacht or seagoing motor cruiser. **Q: Would this work for waterproofing cracks in outside concrete steps** A: Probably would, but I would try concrete first of all to fill the gaps, it would look better. ## Frequently Bought Together - Sikaflex White 291i Multifunctional adhesive sealant for marine applications, 300ml - 10 Gauge Marine Wire 10 AWG Marine Grade Wire,10/3 Triplex Tinned Copper Boat Cable,10 Gauge Oxygen-Free Copper Cable for Automotive RV Boat Speakers Solar Outdoors - 30ft - Sika Sikaflex-221 - Black - Multi-Purpose Polyurethane sealant/Adhesive - Creates Permanent Elastic Seal - Sandable/paintable - Non-Corrosive - 10.1 fl oz --- ## 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.be/products/47904792-sikaflex-291i-white-multi-functional-adhesive-sealant-for-marine-application](https://www.desertcart.be/products/47904792-sikaflex-291i-white-multi-functional-adhesive-sealant-for-marine-application) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-09-16*
