Plaster Conservation

Mitigating deterioration while preserving original decorative finishes and unique elements of earlier craftsmenship, is the main objective of historic plaster conservation. Plaster walls, ceilings, rosettes, cornices, moldings, medallions, cornices, plaques, columns, and capitals contribute to the design and character of historic interiors. Frequently, plaster was finished with elaborate paintings, or large scale murals. Ornamental and decorative plaster preservation as well as mural conservation always amounts to a complex task, involving surface cleaning, filling, inpainting, loss compensation, and varnishing.

In an ideal scenario, historic architectural elements are preserved in place, and restored to their original beauty. Our conservators specialize in plaster preservation techniques that avoid further deterioration, failure, collapse, and the expense of complete reconstruction. This includes testing and analysis of systemic deterioration and original plaster compositions. With this foundation we can design a comprehensive solution for stabilization, filling, replication, and adhesion of missing plaster elements.

Our plaster studios in New York & Los Angeles employ a diverse group of experts in  historic preservation of decorative and ornamental plasterwork. Trained in traditional sculpture, mold making, and casting techniques, our plaster specialists design, fabricate, and implement any type of plasterwork, including architectural sculpture and bas reliefVenetian plaster and scagliola.

The standards for our practice are defined by national and international organizations, including the American Institute for Conservation (AIC), the Secretary of the Interior’s Standards for Historic Preservation, the International Council on Monuments and Sites (ICOMOS), and the International Centre for the Study of the Preservation and Restoration of Cultural Property (ICCROM).
