Description
Marineflex is a one-part, hybrid, high-performance, moisture-curing polyurethane Marine Sealant and structural adhesive. It bonds strongly to surfaces like concrete, steel, glass, aluminium, timber, plastics, polycarbonates, acrylics, brick, GRP (glass-reinforced plastic), marine ply, and metals. You can paint over it for a clean, professional finish.
Marineflex Marine Sealant works for both new builds and repairs on all types of marine vessels. Its strong adhesion ensures long-lasting durability in demanding marine environments.
Use it above or below the waterline. Seal joints, bed fittings on decks and hulls, and seal around hatches and portholes. It also works well for seam filling and structural bonding.
Marineflex is non-toxic, low odour, fast curing, and permanently flexible. It resists stains, slumping, and peeling. You can also sand it for a smooth, high-quality finish.

My usual supplier had run out of the “Flex” I normally buy so purchased Marinflex, worked out well, seals and bonds very well and cheaper than what I have purchased before

I have used Marineflex for 5 years on my ex-lifeboat – perseverance. It’s good stuff, it does not perish, it’s much better than Sikaflex and it’s good value for the cost. I haven’t had any failures caused by using this product and I am just about to use it for the refurb.

I’ve been using Marineflex for sealing various things on my narrow boat for over 15 years now and have always been pleased with the product, the ease of application and finishing, and it does the job very well.
