Sikaflex Self-Leveling Sealant is used to seal horizontal expansion joints in concrete and cementitious slabs such as:

  • Driveways
  • Garages
  • Sidewalks
  • Balconies
  • Pavements
  • Terraces
  • Warehouses
  • Factories
  • Civil Structures
  • Plazas
  • The ultimate performance of Sikaflex® Self-Leveling Sealant depends on good joint design, correct joint preparation and proper application
  • Some substrates require priming. Please refer to the Sikaflex® Primers Product Data Sheet or consult with Sika Technical Services.
  • Do not apply when joint walls are wet or damp and a moisture-vapour-transmission condition exists from the substrate as this can cause bubbling within the sealant.
  • Maximum depth of sealant must not exceed 13 mm (1/2 in); minimum depth is 6 mm (1/4 in).
  • The depth of sealant in horizontal joints subject to traffic is 13 mm (1/2 in).
  • Maximum expansion and contraction should not exceed 25% of average joint width.
  • Use opened cartridges the same day.
  • When applying sealant, avoid air-entrapment.
  • Do not tool with detergent or soap solutions.
  • Since system is moisture-cured, permit sufficient exposure to air.
  • Do not cure in the presence of curing silicone sealants.
  • Avoid contact with alcohol and other solvent cleaners during cure.
  • Allow at least 7 days for sealant to cure under stated conditions when using Sikaflex® Self -Leveling sealant in total water immersion situations or prior to painting.
  • When over-coating with water-, oil- and rubber- based paints, compatibility and adhesion tests are essential.
  • Avoid exposure to high levels of chlorine. (maximum continuous level is 5 ppm of chlorine.)

Irritant; Sensitizer; Combustible Liquid - Contains xylenes, ethyl benzene, isocyanate prepolymer. Can cause skin and/or respiratory sensitization after prolonged or repeated exposure. Skin, eye, respiratory irritant. Avoid skin contact. Use only with adequate ventilation. Use of safety goggles and chemical resistant gloves is recommended.
