Sikafloor 3S is a one-component liquid sodium silicate surface hardener. Sikafloor 3S is odourless, colourless, biodegradable, VOC compliant and reacts chemically to produce a hard, dust-free finish

  • Ready to use.
  • Easy to apply.
  • Non-yellowing. 
  • Good penetration.
  • Colourless and odourless.
  • Improved chemical and abrasion resistance.
  • Reduced dusting on lower quality concrete floors.
  • Complies with today’s environmental, health and safety regulations.
  • Canadian Food Inspection Agency acceptance.

  • Warehouses and industrial plants.
  • Food-processing plants.
  • Stores and shopping malls.
  • Parking structures.
  • Service stations.
  • Offices and multi-residential buildings
  • Sikafloor® 3S should not be applied as a curing compound.
  • Failure to thoroughly wash and remove all excess material from floor surfaces may result in unsightly white stains.
  • Keep from freezing.
  • Not effective on lightweight, extremely porous or worn concrete.
  • Sikafloor® 3S is a colourless solution that will not alter the appearance of the concrete surfaces, therefore, it will not hide serious staining or excessive wear.
  • Concrete less than 3-7 days old may contain excess moisture that will inhibit Sikafloor® 3S penetration into the concrete surface and affect its ultimate effectiveness.
  • For best results, concrete floors should be treated with liquid floor hardener at least 7-14 days after placement or after the cement has had sufficient time to hydrate.
  • Do not apply to areas previously treated with membrane forming sealers unless these sealers have been completely removed

Sikafloor® 3S is odourless, non-flammable and has a low toxicity. Good ventilation is
essential during application. Avoid prolonged breathing of vapours. Consult product
label for additional information.
