Important Considerations:

  • Allow 5 days cure at standard conditions for total water immersion applications.
  • Conduct preliminary tests before over-painting Sikaflex®-11 FC with water, oil, or rubber-based paints.
  • Avoid exposure to high levels of chlorine (Maximum level is 5ppm).
  • Ensure the depth of sealant does not exceed 12mm and not less than 6mm when used as a joint sealant.
  • Maximum expansion and contraction should not exceed 12.5% of average joint width.
  • Avoid applying the sealant when moisture-vapor-transmission condition exists from the substrate to prevent bubbling.
  • Avoid air entrapment during application to prevent bubbling.
  • Permit sufficient exposure to air for proper curing as Sikaflex®-11 FC is moisture-cured.
  • Note that the white colour may slightly discolour/yellow when exposed to ultraviolet rays.
  • Ensure proper application, good design, and surface preparation for optimal performance.
  • Not suitable for use in expansion joints.
  • Provide temporary support for heavy components until Sikaflex®-11 FC fully cures.
  • Avoid using on bituminous substrates, natural rubber, EPDM rubber, or materials that may leach oils, plasticizers, or solvents.
  • Not for use to seal joints in and around swimming pools.
  • Avoid exposing uncured Sikaflex®-11 FC to alcohol-containing products and solvent cleaners.
