Protecting buildings from water penetration

Whether you’re looking to stop a leak, repair an existing roof, or fit a new roof, Bostik has a solution to support the step-by-step process of your next waterproofing project.

Key products in the Bostik waterproofing range include:

  • Flexacryl - a flexible, single coat compound for immediate waterproofing over most conventional roofing substrates
  • Flashband – a self-adhesive flashing tape which bonds instantly to provide a permanent watertight seal

In addition to products that are designed to protect buildings from water penetration, the range also features a Bituminous Black Paint for general weatherproofing of metalwork and roofs, as well as an Aluminium Solar Protector with light and heat reflecting properties.
