Bostik OB1 Sealant & Adhesive Clear 290ml 30617361

Product Features / Specifications:

OB1® offers the ultimate bonding and sealing experience, replacing the need for multiple products such as mastics, wood and PU adhesives, silicones, sanitary, acrylic, and butyl rubber sealants. It can be applied on wet surfaces or even underwater, making it one of the most adaptable adhesives on the market.

Suitable for use on metals (including lead), plastics (PVC & GRP), glass, mirrors, polystyrene, fibreglass, and wood, this odourless sealant and adhesive will never crack or shrink, ensuring a long-lasting finish. OB1® is over-paintable with water-based paints (testing recommended for synthetic paints).

Its unique formulation provides high flexibility and exceptional resistance to UV exposure, fungal, and bacterial attack, maintaining integrity in the toughest environments. OB1® is also VOC-free (EC1+ rated), food safe, and contains no isocyanates, silicones, or solvents, making it suitable for LEED Construction Projects.

Applications and Versatility:

Perfect for construction, marine, automotive, and household applications, OB1® can be used for sealing joints, bonding panels, repairing roofs, fixing guttering, attaching mirrors, and general maintenance. Its ability to adhere to both porous and non-porous surfaces — even when wet — makes it ideal for use in bathrooms, kitchens, outdoor areas, and industrial settings.
