Review: Fix hatch on my kayak - Tube was easy to use in my application gun and spreads pretty good nice and smooth. Very messy for hands so ensure you wear gloves you can throw away after use. It glues well to your hands and taking 2 days to fade lol. But seems to have done a good job fixing both of my hatches down onto my kayak. Had a slight leak in the seals thought I'd fix it in readiness for next season. I read great reviews and this is mentioned as the best as its designed for boats and has resistance to salt water and fresh all good, the adhesion to plastic was reviewed as really good on other Google review sites not desertcart by the way. I've water tested my kayak with water around the seal a good finish no leaks then I chucked z good size bucket of water as a sort of pressure test gave it a good dowsing of water all good no leaks ... I'd tell anyone to buy its worth the extra money. How long will it last hoping few years, plenty left in the tube. Drying time not on the tube but reviews on a Google search said 24 hrs mine was curing in few hours and after 16hrs I was water testing it so its decent. Just messy be prepared to get this stuff in places you didn't want it. I applied a bit too much and white spirits helped clean up a bit. You don't need loads on lesson learnt the second hatch I fitted to my kayak I used less and its sealed well be aware when you apply force if doing a kayak excess Sealand also goes inside the kayak so I got it on my arms and hands without realising it had gone inside kayak hatch rim lol. Enjoy using it havd gun and if fitting to a kayak hatch like me it's good buy it just take it from me less is better.. Next time thin the amount out on kayak lip... im not a robot really used this gloop highly recommend if you need eater tight.

Kev ### ⭐⭐⭐⭐⭐ Does the job *by A***R on 8 August 2026* Sika is good stuff in the marine world ### ⭐⭐⭐⭐ Decent, thick adhesion *by S***A on 15 August 2026* Thought this was really decent, time will tell if it’s any good from a longevity perspective, but I need a product to hold the some aco drains together especially as the builder decided to silicone some corners together. I feel like most builders best friend is silicone. It literally is their answer to most adhesions challenges. I digress, but seriously this felt like a really good, thick product. I removed all the silicone and effectively glued everything back together using this. It’s now been 3 weeks and everything still remains decent. ## 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.tn/products/54682220-sika-sikaflex-291i-marine-sealant-and-adhesive-specifically-designed-marine](https://www.desertcart.tn/products/54682220-sika-sikaflex-291i-marine-sealant-and-adhesive-specifically-designed-marine) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-22*
