OB1® Multi Surface Construction Sealant & Adhesive

OB1® is a hybrid sealant and adhesive designed for a wide range of construction, repair, and maintenance tasks. It is formulated to bond a variety of materials including metals (such as aluminium and lead), plastics like PVC and GRP, glass, mirrors, polystyrene, fibreglass, carbon fibre, and wood. It can also be used in wet conditions and even underwater, making it suitable for situations where traditional adhesives may not perform as well.

OB1® contains zero VOCs and is completely solvent-free, providing an alternative to mastics, silicones, acrylics, PU adhesives, and butyl rubber sealants. Because it does not contain solvents, it will not crack, shrink, or become brittle over time. It can be applied to wet or dry surfaces, shaped or moulded during application, and painted once cured.

Suitable for both interior and exterior use, OB1® offers resistance to mould, mildew, fungal, and bacterial growth. Its flexibility and strong adhesion make it useful across bathrooms, kitchens, roofing, solar installations, marine settings, and general construction work.
