Resumo

A conservação de esculturas exteriores pintadas é um desafio devido à constante exposição a ambientes não controlados. Este artigo descreve a metodologia empregue para conservar uma escultura monocromática em ferro, Tree, de George Lappas, que se encontrava num ambiente costeiro há décadas. A obra apresentava corrosão metálica extensa e deterioração da pintura. Após uma avaliação ética das intenções do artista relativamente à necessidade de uma estabilidade duradoura, considerou-se necessário repintar completamente a escultura. Adotou-se um diagnóstico abrangente, incluindo XRF, XRD, SEM-EDX, colorimetria e medição de brilho, bem como limpeza investigativa. O estudo aborda os desafios para remover várias camadas de tinta e solucionar os problemas de corrosão. O tratamento de conservação envolveu o uso de resina epóxi para preencher as lacunas e sistema de tinta de poliuretano durável. A combinação de técnicas tradicionais e modernas restaurou as qualidades estéticas originais da escultura, e maximizou a sua resistência a condições ambientais agressivas.
