Exterior Walls / Facades

FN® Coating will protect all exterior walls/facades against the devastating effects of ultraviolet radiation, mold, algae deposits, and stains. FN® Nano photocatalytic system effectively increases the resistance of the facades against the spider webs, pigeon excrement, dust and more. It will ensure a long-term preservation of its clean appearance, thereby limiting the erosive effects of repeated mechanical and chemical cleaning. 

When the sun shines on the surface of the facade, it gets very hot. If the surface gets shade, it quickly cools down. Surfaces have a lower surface temperature than the surrounding area. As a result, dust  particles settle on them and condensate the humidity in the air, and due to this, the surfaces are dulled faster by atmospheric impurities creating a favorable environment for the settling of microorganisms. The vulnerability of the facades to soiling, molding and algae is therefore the natural pattern of an aging building.   

Rapid temperature changes on the facade surface cause mechanical stress. Over time, this leads to the development of micro-cracks allowing water to seep in and increasing the potential for mold to penetrate the thermal insulation system. High thermal stress accelerates, coupled with the aggressive effects of ultraviolet (UV) rays, decay of the upper layer of the facade. Furthermore, UV radiation is the main cause of fading color for any facade. 

Facades in large cities and industrial areas are quickly covered with soot, NOx and dirt scattered in the air. In humid climates the facades often suffer the growth of molds and algae. Most solutions to clean and remove dirt from the surface of the facade require a mechanical and/or possibly a chemical action. However, with every cleaning there is wear to the surface layer of the facade, because these methods of cleaning erode the surface layer. And, if the facade is not cleaned for a long time, the dirt penetrates even deeper into the facade layers and the surface can not be cleaned without damage.

1. The Nano-technological protection of FN Nano® photocatalytic system solves at once the 5 major facade problems, maximizing their life, preserving their appearance and minimizing the cost of their long-term maintenance. Detected defects (cracks and peeling facade screed) should be repaired without delay. Likewise, it is necessary to repair badly made or damaged drifts, eaves and gutters, from which water flows onto the facade. After repair and cleaning your facade apply FN® Photocatalytic Film to protect the facade and can last over 10 years. FN® Coatings create a thin layer on the surface of the facade that blocks the UV radiation, so that it cannot reach the substrate. This completely protects it against decay of the organic components of the plaster binder and facade colors. 

Sticky dirt components are “spread-out” with daylight energy and the rest of the dust is removed by rain and wind. Vertical areas remain permanently clean for 10 years or more. Areas treated with FN® Nano Photocatalytic Film do not need to be cleaned!
