Ornamental Plaster Restoration
Utilize this ornamental plaster restoration section to specify the restoration of ornamental cast gypsum plaster, both “run in place” and mold cast types. Decorative plasters such as scagliola and caen stone are not covered in this section.
Ornamental plaster deterioration is most often caused by water infiltration or movement of the supporting construction; prior to repairing or restoring the ornamental plaster the causes of deterioration should be determined and corrected.
For additional information on this subject, refer to Preservation Brief No. 23 – Preserving Historic Ornamental Plaster by the National Park Service, www.nps.gov.
The restoration of flat gypsum plaster is covered in Section 09 03 22 – Gypsum Plaster Restoration.
