Old Montgomery Courthouse - Conproco Corporation

The Old Court House in Montgomery County, Ohio, was completed in 1850. Since that time, 14 Presidents have visited the structure and used its classic front steps as a platform for addressing audiences. While this Greek Revival style courthouse outlived its purpose as Dayton's legal center, it now serves as a cultural center. The courthouse underwent several renovations during the 1900s to accommodate the flow of legal traffic. These renovations had the unintended result of dulling the original architecture. In 2000, Montgomery County and the Montgomery County Historical Society partnered to restore the building, and establish it as a civic focal point. The project budget was 4.2 million dollars. The building's interior and exterior were painstakingly recreated and restored. The limestone exterior had to be repaired and finished with materials which would blend seamlessly with the existing stone. Matrix was used as a repair mortar, not only for its performance and workability, but because it could be color matched on site. To the city inspectors' delight, even the original hammer marks were successfully recreated. M3P was used for the extensive cornice repairs on the gables. The ability of M3P Stain to blend with these large sections contributed greatly to the successful completion of the project.
