The functional coating FN® 2 has been developed and perfected for the functions of air purification and protection against the deposition of microorganisms. It is designed for exterior and interior use. It can be applied to concrete surfaces of raw masonry, stone, ceramics, plaster, as well as to common building surfaces that do not repel water. It differs from FN® 1 coatings by significantly lower transparency and higher efficiency of air cleaning. We therefore recommend its use especially in applications aimed at air purification or protection against microorganisms.

FN® 2 coating is used as a highly effective low-cost technology for cleaning the air from a wide range of pollutants and unpleasant odors (recommended especially for indoor use). It is an effective and more advantageous alternative to conventional technologies for air purification (air purifiers).

The functional FN® 2 coating also serves to create effective and long-term functional nanotechnological protection of surfaces against the deposition of atmospheric dirt and against their attack by fungi, algae and other microorganisms, and against viruses and bacteria. It is therefore also used as an effective technology to reduce the risk of transmitting infectious diseases. The high content of titanium dioxide in the coating layer guarantees extremely effective protection of the substrate on which FN® 2 is applied against “sagging” of paints and decomposition of the binder due to UV radiation. FN® 2 is also used to create anti-graffiti protection.


  • 99.9% protection against UV radiation;
  • There is no disintegration of the binder;
  • Long-term protection without additional maintenance;
  • Protects surfaces against sticky dirt;
  • Super strong self-cleaning effect;
  • High vapor permeability and breathability;
  • Protects against the deposition of fungi, algae and other microorganisms;
  • It prolongs the life of facades and significantly cools their surface;
  • Highly efficient technology for air decontamination (outdoor air purification and reduction of the risk of indoor disease transmission);
  • It maintains high efficiency for a long time with a 10-year guarantee on vertical surfaces;
  • ECO technology – without the use of chemistry;


The coating is slightly transparent with a whitish tinge and its surface slightly chalks. Transparency approx. 50%.
