Sika® FerroGard®-903 Plus FD

Active corrosion inhibitor for reinforced concrete

Sika® FerroGard®-903 Plus FD is a surface applied active corrosion inhibitor, based on organic compounds, designed for use as an impregnation of steel reinforced concrete. It penetrates the concrete and forms a protective monomolecular layer on the surface of the reinforcing steel. Sika® FerroGard®-903 Plus FD both delays the start of corrosion and reduces the corrosion rate. Corrosion protection with Sika® FerroGard®-903 Plus FD increases the service and maintenance life cycles by up to 15 years when used as a part of a complete Sika Concrete Repair and Protection System.

  • Does not alter the water vapour diffusion properties of concrete.
  • Long term protection and durability.
  • Can be applied to the surface of existing repairs and to surrounding areas.
  • Effective against carbonation.
  • Protects both cathodic (principle 9) and anodic (principle 11) zones of reinforcing steel.
