Larsen F1X is a premium professional-grade MS Polymer adhesive and sealant that combines exceptional bonding power with long-lasting sealing performance in a single versatile product. Designed as a true all-in-one solution, F1X replaces the need for multiple products by functioning as a construction adhesive, silicone sealant, sanitary sealant, and mirror adhesive.

Utilising advanced MS Polymer technology, F1X delivers outstanding adhesion to a vast range of construction materials while remaining permanently flexible and durable. It bonds and seals on both dry and wet surfaces and can even be applied underwater, making it ideal for challenging installation and repair projects.

The solvent-free formulation cures through atmospheric moisture to form a waterproof, weatherproof, UV-resistant, bacterial-resistant, and fungal-resistant seal. Unlike many traditional sealants, F1X is virtually odourless during curing and can be overpainted with most common paint systems once cured.

Suitable for use on stone, brick, ceramics, concrete, fibreglass, glass, mirrors, plastics, metals, plasterboard, polystyrene, timber, and zinc, F1X provides exceptional versatility for professional tradespeople, contractors, installers, and maintenance teams. Whether used for fixing, sealing, bonding, or weatherproofing, Larsen F1X offers reliable long-term performance across a wide range of construction applications.
