The most reliable way to seal complex connections is with liquid plastic, since the material conforms seamlessly to any shape. This prevents the formation of joints or transitions that could leak later on.

Liquid plastic is ideal for complex connection details, penetrations, and transitions. It conforms to any geometry and provides a seamless seal without joints.

Common mistakes include:
  • inadequate surface preparation
  • incorrect application of materials
  • lack of system coordination
These often lead to leaks and consequential damage. Training and clear application guidelines are crucial.

Digital tools such as the Triflex Detail and System Finder make it easy to quickly identify the right solution. Factors such as the substrate, intended use, and building component are taken into account.
