FC40 Paintable and Waterproof Sealant and Adhesive for Home and DIY

300ml FC40 Paintable and Waterproof Sealant and Adhesive

FC40 is a paintable and waterproof sealant and adhesive designed for demanding sealing and bonding jobs. It forms a strong, flexible bond and stays permanently flexible after application, so the joint can move with the surface without cracking, splitting, or losing its grip. This makes it a dependable choice for areas exposed to vibration, movement, moisture, and changing temperatures.

One of its biggest advantages is that it can be painted once cured. You can match the finish to the surrounding surface for a neat, professional look, whether you are working on a visible joint or a hidden seam. It is also fully waterproof, so it performs well in wet conditions, including above and below the water line.

FC40 works as both a sealant and an adhesive, which means one product can handle a wide range of tasks on site, in the workshop, or at home. It bonds well to metal constructions and suits both professional tradespeople and confident DIY users who want a reliable, long lasting result.
