OB1 Multi Surface Construction Sealant & Adhesive (290ml Cartridge) is produced from hybrid polymers and is considered the ultimate solution to fixing and sealing. Offering a supreme bond, OB1 sealant is a popular alternative to mastics, PU adhesives and silicones. It can be used on a wide range of materials including aluminium, wood, plastics to metal, carbon fibre, fibreglass and GRP and provides excellent flexibility and resistance to fungal growth.

Designed to maintain a robust bond when cured from -40° up to +120°C, OB1 Multi Surface Construction Sealant & Adhesive is suitable for both interior or exterior applications and will fully cure at a 6mm depth in 24 hours. Due to its hybrid polymer formulation, this high-quality sealant can be applied under water and can even be used to bond floor and wall tiles in swimming pools without the need to drain the pool. It also will not crack, shrink or collapse unlike silicone mastics, so a permanent seal or bond is assured.
