NOxOFF™ Concrete


NOxOFF is a specially formulated coating for concrete, bitumen roofing, and asphalt road surfaces. It is a cost effective TiO2 based photocatalytic product. Activated by natural sunlight and cleaned by the rain, giving us clean air to breathe. NOx particles are turned into nitrate, helping fertilize the soil.

NOxOFF™ Concrete 

NOxOff is a photocatalytic coating for concrete. It’s a cost effective TiO2 based fluid activated by sunlight and cleaned by the rain. It can be applied on freshly casted, still wet, pavement stones but also onto cured concrete both at the factory or as an after treatment. NOxOFF removes 1 kilo NOx per 50 m2/year on average and has a durability of at least ten years.

By applying NOxOFF you will add value and offer a new product to the market without having RD costs. The NOxOFF product is tailor-made, and will be calibrated precisely to your needs and concrete type. NOxOFF fluids are developed and made in Denmark.
