Detoxifying and self-cleaning stain to purify the outside air.

DtoxGuard® Ext is a colorless stain for outdoor porous mineral substrates. It purifies the air by degrading pollution (nitrogen oxides - NOx) by photocatalysis. DtoxGuard® Ext also degrades organic soils that can be deposited on a treated surface. It remains clean by natural rinsing with rainwater.

DtoxGuard® Ext is an impregnating product, non-film-forming, the support thus remains permeable to air and water vapor. Colorless after application, it does not change the appearance or the nature of the treated substrate. In addition, it is UV resistant and does not yellow over time.
