Analysis of ceramic coatings in interventions in architectural heritage

Abstract

The selection of criteria for action, as well as the proper use of appropriate materials and techniques, are decisive for the conservation of architectural heritage. The construction technologies and materials used in historic buildings must be considered in any decision, which involves different criteria at the time of intervention: aesthetic, constructive, historical, physical, chemical, among others. By doing so, it is possible to minimize the incompatibility between traditional and contemporary materials used in heritage buildings. Intervening in historic buildings is an extremely complex task, because bringing together theoretical concepts, old construction techniques and the use of appropriate materials in vogue requires multidisciplinary knowledge involving different areas of knowledge. The aim is to contribute to the investigation of the appropriate use of the most compatible porcelain tiles available on the market to be applied in interventions in pre-existing contexts, along with the successful and unsuccessful examples applied in the city of Belém. thus, the possibilities for preservation actions that are more appropriate for architectural heritage are found, extending its use/function for more years by users and, consequently, bringing new meaning to the building in the urban space, instructing future adjustments without the application of radical contrast to the false history and the technical and material understanding in the correct application in the scope of the choices of porcelain tiles for coatings in the specifications of the floors.
