Use only C2-grade tile adhesive or a compatible MS polymer sealant for installation.

During application:

  • Select the correct collar size for the pipe or drain diameter
  • Stretch the flexible centre carefully over the penetration
  • Position the collar evenly around the pipe or drainage outlet
  • Embed the collar firmly into the adhesive or sealant
  • Remove wrinkles, trapped air and uneven sections
  • Seal all edges and adjoining waterproofing components completely
  • Inspect the installation before applying tiles, screed or protective finishes

Always follow the recommended technical guidelines and waterproofing-system installation procedure for optimum performance.
