Sika FerroGard-903 Plus - Corrosion Inhibitor - Sika

Sika FerroGard-903 Plus is a surface applied mixed corrosion inhibitor designed for use as an impregnation for reinforced concrete.

Features

• Complies with principle 11 of standard EN 1504-9 method 11.3 (application of corrosion inhibitors to concrete).
• Does not modify the appearance of the concrete structure.
• Does not alter the water vapor diffusion properties of concrete.
• Long-term protection and durability.
• Can be applied to the surface of existing repairs and surrounding areas to prevent the development of anodes.
• Protects both cathodic (principle 9) and anodic (principle 11) areas of reinforcing steel.
• Can be applied where other prevention/repair options are not possible.
• Economical extension of the service life of reinforced concrete structures.
• Easy application and economical and renewable treatment.
• Complies with GHS/CLP regulations.
• Can be used as an addition to a simple yet effective concrete repair and protection system.
• Penetration depth can be tested on site using the Sika Qualitative Analysis Test – for further details consult our Technical Department.

Application areas

• For corrosion protection of reinforced concrete structures, above and below ground.
• As a corrosion control treatment for undamaged reinforced concrete when reinforcing steel is corroding or the concrete is at risk of corrosion from carbonation or chloride contamination.
• Sika FerroGard-903 Plus is particularly suitable for extending the lifespan of exposed concrete surfaces with aesthetic value, for example on historic buildings and architectural concrete.

Application

1. Sika FerroGard-903 Plus is delivered ready to use and must not be diluted. Do not shake the product before use.
2. Sika FerroGard-903 Plus must be applied until saturation by brush, roller, low pressure or airless system.
3. After applying the last coat, as soon as the surface becomes dull, clean with low pressure water (water hose).
4. The day following application, the treated surfaces must be cleaned by high pressure washing (10 MPa – 100 bars) in order to eliminate all traces of soluble salts which may have possibly been deposited on the surface.

Consumption

As a general rule: ~ 0.500 kg/m² (~ 480 ml/m²).
For very dense concrete with low permeability, the application rate of Sika FerroGard-903 Plus can be reduced, but not less than 0.300 kg/m² (290 ml/m²).

Conditioning

• 25 L container.
