Sika FerroGard -903+ is a surface applied mixed corrosion inhibitor, designed for use as an impregnation of steel reinforced concrete. Sika FerroGard -903+ is based on organic compounds. Sika FerroGard -903+ penetrates the concrete and forms a protective mono-molecular layer on the surface of the reinforcing steel.
Protection with Sika FerroGard -903+ both delays the start of corrosion and reduces the corrosion rate. Corrosion protection with Sika FerroGard -903+ 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.
For the corrosion protection of steel reinforced concrete structures above and below the ground
As a corrosion control treatment for undamaged reinforced concrete where reinforcing steel is corroding, or is at risk from corrosion due to the effects of carbonated or chloride contaminated concrete
Sika Ferrogard -903+ is especially suitable for extending the service life of aesthetically valuable fair-faced concrete surfaces such as historic structures
