Jacksonville Historic Marble Restoration
This is a historic marble restoration project we completed a few years ago.
The courthouse was built in the early 1900’s and has a beautiful marble floor and wall cladding that had never been refinished. The stone was first cut with resin bond diamonds at 120 grit then we used 120 honing brushes to give the stone a restored hone finish. In the pictures above you can see the unique honing brushes we use in these projects. We also use honing powder to give a honed finish after using diamond pads, but this floor responded better to the honing brushes.
As we made passes over the stone with abrasive diamond disks and honing brushes, it occurred to me just how much time had passed since the floor was installed in 1914. How many life issues were settled over the years in the courthouse. The 1″ thick Georgia Marble, probably classified as Light Creole, came from the Georgia Marble Company quarry in Pickens County Georgia.
In the last picture shown above you can see a before and after detail. There was a thick layer of years of tracked in soil that had been mopped as well as possible over the years. The color was bright and clear after the honing. The wall cladding was actually a polish finish that the city did not choose to restore.
The honing process was aided by our using a truck mounted extraction unit to completely remove the slurry. When we evaluate our system, using this extraction unit is one of our biggest advantages. Our competitors often use a wet vac to remove the slurry and it is never as clean as we are able to get it with our truck mounted extraction unit.
After we refinished the floor we applied a solvent based sealer to the historic marble to help the city with routine maintenance.
