Bostik OB1 Sealant & Adhesive White 290ml – The Ultimate All-in-One Bonding Solution
Bostik OB1 Sealant & Adhesive White 290ml is a professional-grade hybrid polymer adhesive and sealant designed to deliver unmatched strength, flexibility, and reliability across virtually any material. Built for both trade professionals and DIY users, OB1 replaces multiple products in one—saving time, money, and effort on every job.
Engineered with advanced hybrid technology, OB1 provides exceptional adhesion to metals, wood, glass, concrete, plastics (including PVC), and more, making it the go-to choice for construction, roofing, plumbing, and general repairs. It bonds instantly—even on wet surfaces or underwater—ensuring dependable performance in any environment.
Unlike traditional sealants, OB1 is completely solvent-free and odourless, meaning it won’t shrink, crack, or degrade over time. Its permanently flexible formula moves with materials, creating a long-lasting, watertight and weatherproof seal that stands up to the toughest conditions.
Perfect for sealing joints, fixing panels, bonding skirting boards, repairing gutters, or working in kitchens and bathrooms, this versatile adhesive delivers professional results with a clean white finish. It’s also paintable, UV resistant, and mould-resistant, making it suitable for both interior and exterior use.
