Presto was contacted to develop a scope of work for cleaning The Old Scotia Bank Building in San Juan, Puerto Rico. The building’s envelope is comprised of marble travertie panels. This beautiful building material suffered from decades of neglect and had serious black staining on the majority of the surface. Furthermore, local contractors had damaged a nearby building containing the same stone material during a previous restoration service. Presto’s task was to find a way to clean the sensitive material without damaging it, and find a suitable protective treatment to preserve the finish after restoration.
The Presto Team tested several methods of restoration using both chemical and mechanical approaches. While mechanical approaches produced beautiful results, the cost to resurface the material would prove much higher than chemical cleaning and not in the budget. Presto’s uniquely-designed product Stone Restore CB2 produced perfectly clean results without altering the surface of the stone, and the cost of this method of restoration was in line with the owner’s budget.
After the cleaning process, Presto’s LeachStop which was applied after testing and showed an impressive ability to waterproof the surface of the stone. View a video of Presto Restoration Products & Services work on this project: Click here.
