OB1® offers the ultimate bonding and sealing experience. Tried and tested by the trade for over 15 years, OB1® replaces mastics, wood and P.U adhesives, silicone, sanitary, acrylic and butyl rubber sealants, and can be applied on wet surfaces or even underwater.
It can be used on metals (even lead), plastics (including PVC & GRP), glass, mirrors, polystyrene, fibreglass and wood. Our odourless sealant will never crack or shrink, and it is also extremely user friendly and over-paintable with water-based paints (test area required for synthetic).
OB1® has a unique flexibility with high resistance to UV, fungal and bacterial attack. It is also V.O.C FREE EC1+ Rated, Food Approved and contains no isocyanates, silicones or solvents and is approved for LEED Construction Projects.
