Execução de fachada com revestimento cerâmico conforme a NBR 13755

Abstract

This work addresses, through a bibliographic review, the different types of coatings, manufacturing techniques, physical and chemical final properties, the different constituent layers of the ceramic coating on the facades of buildings, as well as the pathologies that occur in this type of coating and a methodology for diagnosing this type of manifestation, so that the problem can be correctly identified. This methodology is basically based on the analysis of the NBR 13755 standard: documentation; visual inspection; data collect; identification of pathological manifestations. The cladding of the façades performs several functions, among them the protection of the building of pathologies. These pathological manifestations are due to several factors, the main ones being: design errors, the use of inadequate construction methods, low quality materials and the lack of control over the execution stages. These conditions interfere with the building's useful life, and the greater the degree of deterioration, the greater the costs for possible repairs, exponentially exceeding the expenses with preventive maintenance. The aim is to disseminate the available knowledge about the correct procedure and the main pathologies in ceramic facade cladding, in order to increasingly reduce the occurrence of these problems, which are costly, both for users and for construction companies, which often are held responsible for the problem.
