Limestone Gazebo Conservation

Site
Senator Rockefeller's DC Estate, Washington, DC, District of Columbia

A limestone gazebo with a cast iron lattice dome and stone pavers, column bases with sculptural lion heads, benches spanning between the bases, columns, with Corinthian capitals, and sculptural lintels is located on the Rockefeller estate in Washington, DC. 

Conservation Solutions, Inc. (CSI) was contracted to perform a conservation treatment of the gazebo. Limestone elements were washed with a non-ionic detergent and biocide; the process was repeated until biological growth was removed. Areas with material losses were patched with color-matched restoration mortar. Salvageable fragments were re-adhered with adhesive mortar. Ferrous staining was reduced using repeated poultice applications until desired results were achieved. CSI conservators provided detailed documentation, including regular and long-term maintenance recommendations.
