Sika FerroGard 903 – Corrosion Inhibiting Impregnation Coating

Sika FerroGard 903 is a high-performance, penetrating corrosion inhibitor designed to extend the service life of steel-reinforced concrete. This innovative impregnation coating penetrates hardened concrete surfaces, diffusing in vapor or liquid form to reach embedded reinforcing steel. By forming a protective layer, it prevents corrosion caused by chlorides and carbonation. Ideal for infrastructure, marine structures, and commercial buildings, Sika FerroGard 903 enhances the durability of concrete without requiring removal of existing material. It is water-based, environmentally friendly, and can be easily applied with a roller or sprayer.
