In Portugal, conservation and refurbishment interventions on
monuments (churches, convents, palaces and fortresses), as well as on historical
centers (dwelling buildings), have been assuming increasing relevance. In order
to guarantee the present requirements of habitability and aesthetic appearance
of the monument without changing its essential character, in conservation
interventions, it is necessary to implement wall-covering solutions compatible
with the background and the pre-existing materials. In this work, the application to
a case study of a diagnosis methodology for the defi nition of the probable causes
of the anomalies and for the evaluation of the state of conservation of renders and
plasters is described. The measures adopted for the repair of the anomalies are
presented and aim at controlling the causes and minimizing their effects.
