Reintegração cromática de superfícies pictóricas contemporâneas com acabamento mate

: um estudo técnico com base no critério da reversibilidade

Abstract

Inpainting contemporary artworks is a task that presents many challenges, which are results from the utilization of new techniques and materials by the artist, many not meant for an artistic use, or of new concepts and ideas, raising specific questions regarding the paradigms and the needs of conservation itself. When dealing with artworks with a matt finish, the surfaces are more susceptible to damages and the presence of homogenous, uniform texture and colour fields ensue an increased hardship obtaining a satisfactory result, based in theoretical criteria and professional ethics, aiming towards maintaining the formal, material, and conceptual unity of the artwork. Thus, it’s intended to circumscribe the main legibility issues present in contemporary artworks through the identification of the main challenges faced by conservators while inpainting this kind of work and the analysis of materials normally used that, after testing, allow promising, possible solutions. To achieve this, the thesis is based on bibliographical research and a questionnaire sent to the professional community, through which six binders were chosen based on the reversibility criteria and were evaluated and tested through spectrophotometric readings, accelerated aging and solubility tests. Through cross-referencing the information obtained on the different stages of the research, the applicability and efficiency of the materials are tested on the inpainting treatment for two contemporary artworks representative of the issues under study.
