Sika FerroGard 903+ is a surface applied mixed corrosion inhibitor, designed for use as an impregnation of steel reinforced concrete and is an improved formulation of the original Sika FerroGard 903. Sika FerroGard 903+ is based on organic compounds and penetrates the concrete and forms a protective monomolecular 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.

Recommended Uses

• 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

Further Features

• Can be applied to the surface of existing repairs and to surrounding areas to prevent the development of incipient anodes
• Protects both, cathodic (principle 9) and anodic (principle 11) zones of reinforcing steel
• Can be applied where other repair/prevention options are not viable
• Economic extension of the service life of reinforced concrete structures
• Easy, economical application, renewable
• Can be used as part of a simple yet effective concrete repair and protection system
• Penetration depth can be tested on site using the Sika “Qualitative Analysis Test” refer to your local Technical Service Department for details
