Sika® FerroGard®-903 Plus is a surface-applied corrosion inhibitor for the steel reinforcement of reinforced concrete structures, designed for use with impregnation. It is based on organic ingredients and penetrates the concrete, forming a protective layer on the surface of the steel reinforcement. It features a dual action by inhibiting the onset of corrosion and reducing the corrosion rate of the steel reinforcement.

Used for:

• Corrosion protection of steel reinforcement in underground and above-ground structures.
• Repair and maintenance of reinforced concrete structures where the steel reinforcement is at risk of corrosion.
• Extending the lifespan of concrete structures with high aesthetic value surfaces.

Features / Benefits:

• Complies with method 11.3 as defined in EN 1504-9.
• Does not alter the appearance of the concrete structure.
• Long-lasting protection and durability.
• Easy and cost-effective application, renewable.
• Can be used as part of a simple and effective repair and protection system.

Technical Information:

• Penetration depth can reach approximately 25 to 40 mm in 1 month.
• Penetrates through diffusion mechanisms in both liquid and gas phases.
• Preliminary testing is recommended to assess the rate of penetration.
