Acrylic Binder Used for the Consolidation of Gilded Surfaces

摘要

The consolidation of the painting layer or plane and carved gildings which represent different types of detachments is an essential operation for the preservation and restoration of the cultural goods of polychrome wood. Our paper focuses on testing a new type of acrylic binder applied on cracks with blind detachments with an OMRON nebulizer with NE-C28P compressor which sprays microparticles of 3μm under a hermetic film that covers the operated surfaces. The experiments have been performed on samples of old gilded wood. The results are compared to those obtained by using the traditional process of peliculization of the acrylic binder over the detached surfaces and with the process of spraying. The analysis techniques used are the optical microscope and SEM-EDX.
