Filling Losses in Paint | Paintings Conservation

This is one of six brochures in the series Paintings Conservation created for conservators of easel paintings, wishing to keep up with current knowledge, and learning how to apply new techniques in their field. This brochure consists of information about the different types of losses found in ground and paint layers on different substrates, historical approaches to and materials for filling, methods for removing old fillings that are no longer suitable, modern types of fills and recipes, and some techniques for fillings and applying texture to fillings.

Knowledge exchange

These six brochures were compiled to serve as a reference, bringing together current practices and new knowledge regarding materials and methods for practical use. The content provided can be used by professional conservators, who are aware of the ethical and contextual aspects and complexity of conservation decision-making.

Conservation knowledge and practice are developing at an increasingly fast pace. In many countries, this knowledge is often concentrated within a relatively small group of conservators and other professionals in larger institutions with the resources to take major steps in the development and application of new methods for preservation and treatment of paintings. New publications on focus topics are often issued through journals or editions that are costly and not easily available to the conservation field. Thus, accessing such knowledge and integrating into practice can be challenging. These brochures are designed to help bridge this gap. They are also a tool for mid-career professional conservators seeking to refresh and update their knowledge. The content is intended as a snapshot of up-to-date developments in these six focus areas and should not replace academic training in the field of painting conservation.

The need for this reference material became apparent during a series of masterclasses and conferences, organized in the period 2012-2020 by Cultural Inventory Foundation (SCI) in India, Russia and Cuba. These gatherings, focusing on mutual exchange and deepening knowledge in relation to the local contexts, were organized in association with SRAL - The Conservation Institute, the RCE, and Dutch embassies in the partner countries of the International Heritage Cooperation programme.
