Product description
Bostik OB1 Sealant & Adhesive Clear 290ml
is a professional-grade, all-in-one hybrid polymer designed to replace multiple products with one powerful solution. Engineered for ultimate bonding, sealing, and gap filling, OB1 delivers exceptional strength, flexibility, and durability across a wide range of materials—making it a go-to choice for trade professionals and DIY users alike.
Unlike traditional sealants, OB1 can be applied **directly onto wet surfaces—even underwater—**without compromising performance. Its advanced formula creates a permanently elastic, high-strength bond that won’t shrink, crack, or degrade over time, ensuring long-lasting results in even the toughest environments.
This versatile adhesive bonds effortlessly to metal, glass, wood, PVC, GRP, mirrors, fibreglass, and more, eliminating the need for multiple sealants or adhesives on-site. Whether you're fixing guttering, sealing joints, bonding panels, or carrying out general construction and roofing repairs, OB1 provides reliable, trade-quality performance every time.
Formulated to be solvent-free, odourless, and VOC-free, OB1 is safer to use and environmentally friendly, while still offering high resistance to UV, weathering, chemicals, and fungal growth. It remains flexible after curing, absorbs movement, and can be painted over with water-based paints for a clean, professional finish.
Ideal for indoor and outdoor use, including kitchens, bathrooms, roofing applications, and construction projects, Bostik OB1 is the ultimate multi-purpose sealant adhesive trusted by professionals across the UK.
