Sikafloor® CureHard LI

Lithium silicate liquid hardener and densifier

Sikafloor® CureHard LI is a water-based lithium silicate blend for hardening and densifying of fresh and hardened power trowelled or polished concrete surfaces. It is less prone to the formation of persistent efflorescence in cases of over dosage compared to similar products based on sodium or potassium silicate. It improves surface performance and resists the harmful effects of traffic wear and weathering. Once applied to a concrete surface Sikafloor® CureHard LI penetrates the concrete texture and is initiating a chemical reaction and subsequent crystallization of reaction products which result in filling of the concrete surface pores.

  • Improves performance, dust reduction and abrasion resistance of new or old concrete.
  • Sealing and impregnation of concrete surface.
  • Easy, one step application. No scrubbing. No flushing.
  • Reduced appearance of efflorescence, compared to crystalline sodium or potassium based hardeners.
  • No enhancement effect on the floor colour.
  • Gives the concrete surface silk gloss appearance.
  • High gloss of the surface after each regular cleaning.
  • Breathable and UV stable. Will not yellow, discolour, peel or flake.
