Sika FerroGard903 Plus – Premium Corrosion Inhibitor for Concrete Protection

Sika FerroGard-903 Plus is a high-performance surface-applied corrosion inhibitor designed for steel-reinforced concrete. Based on advanced organic compounds, it penetrates deeply into concrete to form a protective monomolecular layer over reinforcing steel. This innovative formula delays corrosion onset and reduces corrosion rates, significantly extending the service life of concrete structures by up to 15 years when used as part of Sika’s comprehensive Concrete Repair and Protection System.

• Ideal for undamaged concrete exposed to carbonated or chloride-contaminated conditions.
• Extends the lifespan of aesthetic, fair-faced concrete, including historic and architectural structures.

Features and Benefits

• Conforms to EN 1504-9, ensuring anodic control with method 11.3 application.
• Preserves the appearance and vapour permeability of concrete surfaces.
• Offers long-term durability and easy, cost-effective application.

• Clean surfaces with low-pressure water after the final coat dries to a matte finish.
• Pressure wash treated areas the next day to remove surface salts.

Coats Required

• Vertical Surfaces Typically 2–3 coats; additional coats may be necessary for dense concrete.
• Horizontal Surfaces Saturate with 1–2 coats, avoiding ponding.

Overcoating

• Compatible with Sikagard hydrophobic impregnations, Sikagard breathable coatings, and Sikafloor products.
• Ensure compatibility when using non-Sika products by consulting technical support or conducting trials.
