Abstract: The use of durable products on the external surfaces of buildings ensures high performance and low maintenance. The world market in recent decades has developed a wide range of solutions of limited thickness coatings; the Italian territory is particularly interested due to the strong link, by tradition, with plaster as surface finishing. The knowledge of the performance over time of such innovative products is one of the main research activities of the Italian network on durability and becomes essential due to the new EU regulation No. 305/2011 which introduced, among the requirements for the construction works, sustainability and durability with it. The research concerns the assessment of the durability of some innovative coatings based on acrylic-siloxane resins, in three different colors. The parameters investigated are: the surface appearance, by scanning electron microscope and optical microscope, the color, by spectrophotometer, the absorption of water and the wettability by contact angle measurement. The paper reports the results of the experimental study on siloxane coatings, produced by Hydratite Srl, performed according to the ISO 15686, by monitoring the behavior over time of samples artificially aged in climatic chamber with variable temperature and relative humidity, rain and UV irradiation and samples exposed outdoors, as well as the monitoring of a case study, a residential building, for a period of over a year. The results demonstrate the effectiveness of the coating and its ability to maintain high performance over time of hydrophobicity and maintenance of the color.
