Duroseal 40FC is a fast-curing, flexible polyurethane sealant formulated for sealing joints and cracks in both vertical and horizontal surfaces. It delivers outstanding adhesion, flexibility, and durability across a wide range of construction materials, including concrete, masonry, and pre-cast panels. Its one-part moisture-curing formula makes it easy to apply, and once cured, it resists weathering, movement, and UV exposure — making it ideal for both internal and external use.

Whether used for movement joints, expansion joints, or facade seals, Duroseal 40FC provides long-term sealing performance with excellent elasticity and resistance to joint movement.
