Abstract: This paper presents historical and characterization studies undertaken to: a) clarify technical interpretation of lime-stucco and plasterwork by historic architectural treatises, and b) better understand the intentions of the early designers and plasterers: the used proportions and sizing of materials, the coverage achieved using different plasters, the nature and composition of the materials, and the causes and forms of decay of stuccos and plasters. Historical studies are important for determining the most effective courses of actions with regard to the preservation of cultural heritage, as respectful as possible to the original nature and materials of the historical buildings. The present paper includes the history of the stuccos and plasters as well as the characteristics of the materials used in plastering and the tools to model in relief. In addition, were carried out an "in situ" inspection and laboratorial analysis, as TGA, XRD, EDS and SEM on decorative and plain plasters from Aveleiras House. As a consequence of this study it was possible to quantify the percentage of binder in the mortars and to identify the causes of decorative plasters decay, suggesting their bio deterioration.
