FERROSEAL-CSI is an aqueous solution with high penetrating properties. It is a surface applied corrosion inhibitor, designed for use as an impregnation of steel reinforced concrete. It has the ability to migrate through concrete and to form a protective layer on the surface of the reinforcement steel.
- It extends the working life of the structure.
- It inhibits the start of corrosion in new structures.
- It reduces the corrosion rate on existing structures.
- It does not change the appearance of the concrete structure.
- It does not alter the water vapour diffusion properties of concrete.
- It is easy to apply.
FERROSEAL-CSI is used as a precautionary corrosion protection of steel reinforced concrete structures above and below ground. ALSO it is ideal for repairs of reinforced concrete. Furthermore it is suitable as an anticorrosive protection for structures of reinforced concrete that are exposed on aggressive environment such as bridges, aqueducts etc.
Substrate
The substrate must be dry, sound and free of dust, grease, loose materials, paints etc. If cleaning is required it is recommended to be done by water blasting. The surface must be dry before the application of FERROSEAL-CSI. Damaged concrete must be first repaired, (removal of loose concretet, restoration of the reinforcement, reprofilling) by using the proper repairing products.
Application
FERROSEAL-CSI ir ready to use and should not be diluted with water. It is applied on the substrate by spraying, by brush or by roller, until the surface is fully saturated. Usually 3 to 5 layers must be applied to achieve the minimum required consumption. Each layer is applied after the previous one has dried. To increase the migration speed of FERROSEAL-CSI inside concrete, the surface can be sprayed with water 1-2 times after 2-3 days of the application. In case the treated surface with FERROSEAL-CSI will be later covered by paint or by a repairing mortar, this can be done if it has been previously mortar, this can be done if it has been previously water blasted (not earlier than 2 days after the application of FERROSEAL-CSI).
