Product description

Bostik OB1 Sealant & Adhesive Brown 290ml

Need a reliable, all-in-one sealant and adhesive that performs in any condition? The Bostik OB1 Sealant & Adhesive Brown 290ml is a premium hybrid polymer solution engineered for maximum bonding strength, flexibility, and long-term durability across construction, roofing, and general building applications.

Designed to replace multiple products in one, OB1 works as a sealant, adhesive, filler, and grab adhesive, eliminating the need for silicones, PU adhesives, mastics, and acrylics. This makes it a must-have for tradespeople and DIY users looking to save time while achieving professional results.

Its advanced hybrid formula delivers exceptional adhesion to almost any material, including wood, metal, concrete, glass, plastics, mirrors, stone and more—without the need for primers. Whether you’re sealing joints, fixing trims, or bonding structural components, OB1 provides a strong, permanent hold with flexible movement.

What truly sets OB1 apart is its ability to work in real-world site conditions. It can be applied on wet surfaces and even underwater, allowing jobs to continue regardless of weather or environment—ideal for roofing, external sealing, and emergency repairs.

The solvent-free formulation ensures no shrinkage, cracking, or brittleness over time, while offering excellent resistance to UV, weathering, chemicals, and temperature extremes (-40°C to +120°C).

Why Bostik OB1 Stands Out

  • All-in-one adhesive & sealant – replaces multiple products
  • Bonds virtually any material with no primer required
  • Works on wet surfaces & underwater – perfect for UK conditions
  • Will not shrink, crack or become brittle
  • Flexible, high-strength bond for movement joints
  • UV, weather & chemical resistant for long-term durability
  • Mould & bacteria resistant – ideal for kitchens & bathrooms
  • Paintable finish for a clean, professional look

Ideal Applications

  • Roofing repairs, flashing, and gutter sealing
  • Timber, trim, and panel bonding
  • Bathrooms, kitchens & sanitary sealing
  • Expansion joints & structural connections
  • Automotive, marine & industrial use
