Product description
Bostik OB1 Sealant & Adhesive Terracotta 290ml
Need a high-performance sealant that blends seamlessly with brick, tile, and terracotta finishes? The Bostik OB1 Sealant & Adhesive Terracotta 290ml is a professional-grade hybrid polymer adhesive engineered for maximum strength, flexibility, and a clean, colour-matched finish across roofing, construction, and external applications.
Designed as a true all-in-one solution, OB1 replaces traditional silicones, PU adhesives, mastics and acrylics—delivering exceptional bonding strength on virtually any material, including brick, concrete, metal, wood, glass, plastics and tiles.
Its advanced hybrid formulation allows application in real-world site conditions, meaning it can be used on wet surfaces and even underwater, making it perfect for roofing repairs, external sealing, and urgent jobs where weather is a factor.
Unlike standard sealants, OB1 is solvent-free, ensuring it will never shrink, crack, or become brittle over time, while maintaining a permanently flexible, high-strength bond that absorbs movement and vibration.
Built for durability, it provides excellent resistance to UV, weathering, chemicals, and temperature extremes (-40°C to +120°C)—making it ideal for long-term external use in harsh UK conditions.
