PFL C2 Hard

Advanced Economical Lithium-Silicate Hardener & Densifier for Concrete.

C2 Hard™ is the advanced economical, hardener and densifier for concrete surfaces and a much more effective alternative to conventional sodium or potassium silicate hardeners. This patented lithium silicate treatment deeply penetrates and reacts with the concrete to produce insoluble calcium silicate hydrate within the concrete pores.


  • Easy to apply with little or No Production “Down Time”. Cures quickly. Floor can be put into service immediately after the application process is complete..
  • Excellent Penetration. Patented formulation of C2 Hard™ contains a highly reactive lithium catalyst, which achieves a much greater penetration into the floor surface.
  • Eliminates Dusting. C2 Hard™ eliminates efflorescence and prevents dusting making concrete easy to maintain.
  • Greater Abrasion Resistance. Concrete floors treated with C2 Hard™ will significantly improve abrasion resistance, in comparison to conventional sodium or potassium hardeners.
  • Cost Effective. C2 Hard™ improves performance, appearance and light reflectance of new and old floors.
