Historic building clay sculpture protecting and repairing method

Abstract

A historic building clay sculpture protecting and repairing method comprises the steps of recording original shapes of clay sculptures at first, building a ceiling, using filtered tap water or distilled water, toothpaste and toothbrushes to clean away dirt on the surfaces of the clay sculptures, removing air-slake crisp alkali layers of the clay sculptures, carrying out salt elimination on the clay sculptures, grouting tung oil mortar into slits, cavities and holes of the gray sculptures to repair the clay sculptures, using paper strip mixed lime mortar to repair the damaged and incomplete portions of the clay sculptures or rebuilding the clay sculptures according to the recorded original shapes of pictures of the clay sculptures, using natural pigments and lime paste to manufacture color lime paste according to the recorded color of the original shapes of the clay sculptures, plastering the surfaces of the clay sculptures with the color lime paste, painting the clay sculptures with corresponding natural pigments according to the recorded color of the original shapes of the clay sculptures, painting the whole surfaces of the clay sculptures with tung oil for once to three times to seal and protect the clay sculptures, and establishing scientific clay sculpture repairing files after repairing.
