is a colourless stain designed for porous external mineral materials. It purifies the air by breaking down pollution (nitrogen oxides – NOx) by photocatalysis. DtoxGuard® Ext also breakdowns organic soling that can be deposited on treated surfaces. These remain clean by natural rinsing by rainwater.
DtoxGuard® Ext is a non-film forming impregnation product, the material remains permeable to air and water vapour. Colourless after application, it does not change the appearance or the nature of the treated material. It is also fully resistant to UV rays and does not yellow over time.
