Product description

Bostik OB1 Sealant & Adhesive Beige 290ml

Looking for a high-performance sealant that blends seamlessly with neutral surfaces? The Bostik OB1 Sealant & Adhesive Beige 290ml is a professional-grade hybrid polymer adhesive designed for maximum bonding strength, flexibility, and a clean, colour-matched finish across construction, roofing, and interior applications.

Built using advanced hybrid technology, OB1 delivers exceptional adhesion to virtually any material, including wood, concrete, brick, metal, glass, plastics and tiles—without the need for primers. It’s the ideal choice for beige window frames, stonework, render, and internal finishes, where both performance and appearance matter.

Unlike traditional silicones or mastics, OB1 works as a sealant, adhesive, filler, and grab adhesive in one, reducing the need for multiple products on site and saving time. Its solvent-free formula ensures no shrinkage, cracking, or brittleness, while maintaining a strong, permanently flexible bond that absorbs movement and vibration.

Designed for real-world conditions, OB1 can be applied on wet surfaces and even underwater, making it perfect for roofing repairs, external sealing, and emergency jobs where weather is a factor. It forms a fully waterproof, weatherproof seal with excellent resistance to UV, chemicals, and extreme temperatures for long-term durability.

Additionally, OB1 is odourless and resistant to mould, fungal, and bacterial growth, making it suitable for both interior and exterior environments where hygiene and reliability are essential.
