The use of photocatalytic products for surface coating of buildings contributes to thesustainability of building interventions, due to the reduction of some atmospheric pollutants andself-cleaning attitude. The world market produces a wide range of coatings, applied in limitedthickness, transparent and opaque, high initial performance, although data on their durability arestill missing. The knowledge of the performance over time of such innovative products is necessaryaccording to the new EU Regulation No. 305/2011, which introduced for construction works, theseventh requirement on their sustainability and particularly their durability. The study concerns theevaluation of the durability of white photocatalytic paint, TX Active cement-based. Themethodology is based on ISO 15686 and consists in monitoring the most significant selectedparameters, during laboratory accelerated aging tests and natural environment exposure. Measuredperformance were the morphological appearance of the surface, the photocatalytic activity and thecolor. The results obtained demonstrate the efficiency in time and the maintenance of performanceof the photocatalytic paint, above limits defined by standards and conservation of color.
