A comprehensive joint sealant offering for the construction industry, providing reliable, flexible and waterproof joints for a broad range of applications.

As a leading global specialist in adhesive and sealant manufacturing, we’re dedicated to developing innovative products that respond to the highest standards and customer requirements in the construction market. 

You’ll find Bostik sealant products used for, façade & roofing systems, wall panels and partitions, weatherproofing and windows and doors. Our smart sealants are used for a broad range of applications in construction projects ranging from small domestic renovations, all the way up to river-spanning bridges and skyscrapers. 

Our customers benefit from our range of multi-purpose sealants, 2-in-1 sealants and adhesive products, as well as our innovative expansion joint technologies and quick-curing domestic range for creating fast, reliable joints in wet conditions. 

Many of our smart sealants are recognised around the world for use in domestic and large-scale construction projects. Innovative products such as the Bostik Seal N' Flex® range are at the forefront of sealant technology that is well known and specified.


Bostik Polyurethane (PU) sealants are some of our strongest sealant technologies. Coupled with high levels of flexibility, these sealants are ideal for glazing or construction joints as well as being highly resistant to weather conditions, UV exposure and pollution.

We provide 1-part polyurethane solutions as they are convenient and easy to use. Our polyurethane sealant range includes both low and mid modulus products, allowing you to select the most appropriate level of elasticity for your individual needs.  

Throughout the process of formulating our silicone sealant products, we not only strive to comply with the latest building codes and environmental standards, but also to ensure that our range of solutions continually meet the evolving demands of the field of construction. 

Bostik polyurethane sealants benefit from greater joint movement capability over conventional silicone sealants and have greater durability when exposed to fluctuating weather conditions as well as being UV resistant. This makes this product perfect for sealing larger joints between building materials which can be concealed by painting over with acrylic based paints.


Using the benefits of our Modified-Silyl Polymer (MSP) technology, you can be certain that you a using a product that has been developed to produce a seal that waterproofs and weatherproofs a wide variety of building materials well into the future.

Furthermore, this formulation is free of solvents and other hazardous chemicals to produce an environmentally friendly finish.

The secret lies in the unique hybrid formulation, where the strength of a polyurethane is combined with weathering resistance of silicones to create a new product technology. 

This means Bostik’s range of MSP technology-based products offer:

  • Greater flexibility over broader temperatures while offering greater heat resistance
  • Solvent-free and isocyanate-free formulations that make them ideal for use around the home or for green build construction
  • Can be painted over with water-based or acrylic paints
  • Adhesion to a greater number of building materials and substrates
  • Fast curing properties that will not slump or bubble
  • Easier to tool out even in colder temperatures


Fire and smoke can cause the greatest damage to any building and in many cases; it leaves the building beyond repair. Aside from the physical damage done to the building, this can also leave behind a significant financial and emotional burden to those impacted by it.

Bostik’s range of fire rated sealants compartmentalising (or limit fire and smoke) to one area of the building. This means that the spread of fire and smoke is significantly reduced or slowed down. Bostik fire rated sealants work effectively as a fire retardant between ceilings, beams and joints to stop fires from spreading. 

All Bostik fire rated sealants have a minimum Fire Test Certification of AS1530.4 and AS4072.1.

Bostik fire rated sealants cure to a tough yet flexible seal that offer fire resistance to buildings and building materials. This prevents the spread of fire and smoke and seals vertical and horizontal joints across various substrates such as in situ concrete floors and walls, precast and tilt up panels, brickwork & blockwork, rendered masonry, plasterboard and fibre cement sheet.


Silicone sealants are a versatile formulation allowing for broad application. Bostik silicone sealants are available as acid-free formulations - ideal for more sensitive substrates such as concrete and natural stone or acetic cure to aid in better sealing between two surfaces.

Throughout the process of formulating our silicone sealant products, we not only strive to comply with the latest building codes and environmental standards, but also to ensure that our range of solutions continually meet the evolving demands of the field of construction. 

Bostik silicone sealants form a tough, flexible rubber that can maintain its integrity for years and years. That means Bostik silicone sealants are perfect for sealing out water or weatherproofing to prevent costly degradation or damage to other materials around the home.
