During installation:

  • Measure and cut the tape to the required length
  • Remove the protective release liner gradually
  • Position the tape accurately over the joint or vulnerable area
  • Press the tape firmly onto the prepared substrate
  • Use a suitable roller to achieve uniform contact and eliminate trapped air
  • Ensure all edges are securely bonded
  • Maintain sufficient overlap between adjoining tape sections
  • Avoid wrinkles, folds and excessive stretching during application
  • Inspect the completed installation before applying protective finishes

Always follow the Siegelt Technical Data Sheet and recommended surface-preparation guidelines for optimum adhesion and waterproofing performance.
