Permanent Floor Hardener & Dustproofer


HARDOSIL is a viscous milky white liquid suitable for spray or brush application to concrete and terrazzo surfaces. It reacts with the free lime and carbonates in concrete to form an insoluble gel that fills all pores and voids to form an impermeable surface that reduces the penetration of chemicals, oils, grease and water. Applied to new or old floor surfaces it yields dust free, impact resistant and hardwearing surface thereby extending the floor life.


HARDOSIL is recommended for use on all interior and exterior surfaces where hard, impermeable, weather resistant and dust free surfaces are desired, without affecting the natural appearance of concrete or terrazzo. Some typical application areas are

  • Industrial Floors
  • Warehouses
  • Aircraft Hangars
  • Car Parks
  • Concrete Roads
  • Garages
  • Chemical Plants
  • Dams
  • Dairies
  • Water Reservoirs
