OB1 Multi-Surface Construction Sealant & Adhesive is going from strength to strength

Published: 9 May 2022 - Neil Mead

OB1 is one of the fastest growing sealants on the market, with sales up 70% year on year. Our multi-surface sealant and adhesive is a hybrid polymer formulation for ultimate bonding and sealing which has been 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 all metals (even lead), plastics (including PVC & GRP), glass, mirrors, polystyrene, fibreglass and wood. Our odourless sealant does not contain any solvents and will never crack or shrink. It is also extremely user friendly and over-paintable with water-based paints (test area required for oil based).

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 therefore it has been approved for LEED Construction Projects.

OB1 can be found in most builder & DIY merchants such as Screwfix, Selco, Brewers, Wickes, Dulux and B&Q trade points.
