The travertine veneer had numerous former repairs and this location of attempted graffitti removal was a typical example of the overall condition of the exterior. In this case we were able to remove the deep-seated stains with a solvent-based poultice
Most of the lower wall was stained due to the proximity of the landscape watering system and the daily soaking of the stone.
Tannens from the potting soil of the planted area would solubilize and leach into the matrix of the travertine from below.
Here is a before and after image showing the dramatic difference after removal of the top surface soiling the stone.
This was achieved using a very light abrasive process to remove the soiling without significant removal of the substrate.
Former repairs also included some poorly executed patches at various locations
Our repair techniques also included complete removal of stone panels in order to re-attach, repair and reinstall the veneer components.

Another repair location, this time adjacent to the main entry
There were also numerous locations of old steel anchors that formerl supported signage of previous tenants.
After removal of the steel, patching and cleaning improved the overall apppearance dramatically
Another major component of the exterior was a glass mosaic mural originally fabricated and installed by the MIllard Sheets Studio
Over the years the grout between tesserae had slightly degraded and showed some loss in many areas
The repair plan included replacement of this missing grout, as well as general cleaning and application of a color-enhancing sealer to all surfaces of the mural
Here grout has been applied and is stabilizing prior to the excess material being removed from the glass tesserae surfaces

The other major facade decorative feature was this leaded-glass mural over the south elevation entry
Designed and fabricated by the same Millard Sheets Studios, it incorporated traditional leaded-glass techniques
A rolling tower allowed unhindered access to both interior and exterior surfaces of the mural.
After cleaning the entire surface, new putty was rubbed into the lead cames supporting the individual glass tesserae.
MIssing glass portions were repaired rather than replaced to preserve the original historic material
Color-matched acrylic adhesives were used to re-attach broken segments and fill in minor gaps
