The hygric properties of building materials are related to condensation phenomena and biological contaminants such as fungi infestations, especially in building environments. If the relationship between mould growth and hygric properties is identified and the appropriate building materials are used indoor, it can protect indoor environment from infection of mould. The purpose of this study is to find the relationships between sorption properties and mould germination/growth on wallpapers. An experimental study was conducted to characterize the sorption properties of the selected wallpapers. The sorption properties of the selected wallpapers were obtained at various relative humidity conditions. Then, the selected wallpapers were inoculated with three fungi species and mould germination/growth rates were observed. The correlations between sorption properties and mould germination/growth rate were analyzed. The results showed that the wallpapers that had high sorption properties, which resulted in higher antifungal performance compared to the wallpapers with lower sorption properties.
