Abstract

A composition of a solution of a metal salt of a dioic acid that provides corrosion resistance and moisture resistance is disclosed for application to post-construction materials. The composition may further include an effective amount of a thinning agent, e.g., isopropyl alcohol, ethanol, xylene or similar composition for application directly to the surface of the post-construction material. The composition is effective for reducing corrosion of post-construction materials, including unreinforced concrete or reinforced concrete, and reduces the permeation of moisture and/or the extension of cracks/fissures within the post-construction material. The composition may be applied to the post-construction material through brush applications, spray applications, mist applications or the like.
