Abstract
O presente artigo tem por objectivo fazer um levantamento da informação existente sobre os produtos consolidantes e hidrófugos aplicados em intervenções de conservação em monumentos portugueses. O levantamento teve por base fontes documentais dos arquivos da ex-Direcção Geral dos Edifícios e Monumentos Nacionais (DGEMN) e ex-Instituto Português do Património Arquitectónico (IPPAR) relativas ao período entre 1952 e 2002. Verificou-se que em 30 % das intervenções não se sabe quais foram os produtos empregues e que nos restantes casos apenas nas intervenções mais recentes é rigorosa a documentação. Os resultados também dão conta de um uso generalizado de alcoxissilanos. Dada a importância da documentação relativa às intervenções efectuadas no passado, é proposta uma ficha para a documentação dos tratamentos de consolidação e hidrofugação.
he present article intends to gather the available information about consolidants and water repellents, which were applied in restoration campaigns in Portuguese monuments. The survey was based on documents from the ex-DGEMN (General Directorate forNational Buildings and Monuments) and ex-IPPAR (Portuguese Institute for Architectonic Heritage) archives, concerning the period between 1952 and 2002. It was noticed that in 30% of the interventions the information about the used product was lacking and from the other cases, only in the most recent interventions rigorous documentation was found. Results also show a generalised used of alkoxysilanes. Owing to the importance of documentation past restoration interventions, a data-sheet for documenting the useof consolidants and water repellents is proposed
