Abstract (EN): Non-destructive techniques are essential to detect common pathologies and analyse the building behaviour. Infrared thermography is a testing technology that has been applied to buildings diagnosis for some decades. However, there are still some applications which are not yet completely explored like the detection of micro-cracks on façade coating materials. In this paper we present a brief introduction of the fundamentals of infrared thermography as well as the results of wetting and drying processes of wall coating samples with micro-cracks carried out in laboratory with very closely controlled climatic conditions. The results of an in situ campaign to evaluate this pathology in two distinguished façades are also presented. This study reflects on the limitations of the application of infrared thermography to access micro-cracks and clearly demonstrates the difficulty on controlling measurements in field conditions due to the wide range of parameters that may affect the thermograms. © (2014) Trans Tech Publications, Switzerland.
