Abstract (EN): This paper reports the results of an extensive experimental characterization of the sorption isotherms, vapour permeability and Moisture Buffer Value (MBV) of finishing solutions that are commonly applied on buildings interior surfaces. The experimental and analytical procedures followed either international standards or well-established methodologies, supporting an innovative analysis of coated renders moisture behaviour. The results support the discussion on the relevance of finishing materials contribution to a room¿s hygroscopic inertia, and the influence of finishing coatings on that contribution. A renewed interest on the influence of hygroscopic inertia in the moderation of relative humidity variation was the main motivation for this study.
