Abstract

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