Install Siegelt Sealing Membrane only on a clean, stable, dry, and properly prepared surface. Use C2-grade tile adhesive or a compatible MS polymer sealant for secure and efficient bonding.

Ensure that:

  • Membrane sheets are properly aligned and firmly embedded
  • All overlaps and joints are completely sealed
  • Corners, drains, and pipe penetrations are treated using suitable accessories
  • Air pockets and wrinkles are removed during installation
  • The installed membrane is inspected and tested before applying tiles or protective finishes

Always follow the recommended installation method and technical guidelines for optimum waterproofing performance.
