CREPEX® is a water-based product, with 80% of its volume consisting of a dispersion that is commonly mixed into concrete. Metal parts of buildings affected by corrosion can also be treated with CREPEX® after the damaged concrete is removed. Applying this coating stops the corrosion process and its further spread. Further degradation and erosion can be prevented by mixing CREPEX® into the new concrete applied to the area to be treated.
