Self-cleaning walls, facades and roofs

Multifunctional coatings are the result of the application of knowledge in the field of nanotechnology. Represents the second generation of the effect of photocatalytic coatings. They are absolutely the most effective photocatalytic coating effect on the world market. Competitive products outperform its performance to a hundred times.
If the surface is painted buildings listed functional coatings acquires a strong self-cleaning and dirt deposited on him.
dirt, which is deposited on the surface of the facade, roof and building structures from contaminated air vehicles, fossil fuel combustion boilers and industrial plants can quickly spoil the appearance of even the most representative buildings. Restore the look clean often requires relatively large expenditures on cleaning with chemicals and water pressure.
surface layer formed by the functional coating operations, when activated by ultraviolet light (some daily) as a catalyst for the oxidation reaction between atmospheric oxygen and the oxidation of a substance with layers to touch. Is the complete oxidation of the particles. This effect is called photocatalysis. It is powered by light and is, in contrast to chemicals, inexhaustible.

Self-cleaning effect:
. soot and dust particles in air pollution particles tend to agglomerate inorganic adhesive compositions and water-insoluble organic compounds which form very well adheres to the surface of the facade
When it is ON, the light of the active functional area of the air flow is a carbon black or other microscopic particles of dirt immediate response viscous organic substances with oxygen. They are spread over a relatively short period of time with a molecule of water, carbon dioxide and other health-threatening agents. Neoxidovatelné dust particles then not without glue container to the wall surface located and removed therefrom by rain and wind.
Highly oxidation of the surface of the functional coating is formed very effectively protects the surface of the building, and not only against dirt, but also against fungi and algae ingrowth. Photocatalytic effect destroys their disputes and prevents the development. Prevents settlement and subsequent Mosses and lichens.
Photocatalysis also prevents the telescope surface structures cobwebs cedivečky zápřední (Dictina cicica) that are deposited on building plasters. Functional coating surface treatment of the facade to the spider becomes annoying and cobwebs by the photocatalytic effect on him can not hold.

Consequences for building owners
described the functional properties of the activated surface of the film works in conjunction with its extreme performance photocatalytic effects for many practical design of the owner:

1. Direct financial impact -  reducing the cost of maintaining a clean appearance of the building
manufacturer guarantees the self-cleaning feature functional surface on vertical surfaces up to 10 years, and on the slopes of the direct effect of snow and rain 6 years, even in very polluted environment of large cities, roads and industrial areas. In an environment with less pollution may be to maintain full functionality of the functional surface treatment and coating times higher.

2. The indirect effect of the commercial  – attractive appearance of the building
from the outside is one of the most important factors that affect the rental rate, and thus the income from them. The area covered by the functional layer remains clean and neporůstá fungi, algae and lichens and mchów.Nie require maintenance. If no mechanical removal of the functional layer or the imposition of any other material in theory, is not life and functionality of the time limit. Cladding treated with a functional coating to ensure that their neat appearance will be therefore a long period of time.

3. Protection against graffiti
thick layer (layer 6-7) functional coatings for protection features graffiti. Coated on the surface of the functional is difficult to “catch” spray nib quickly clog pores and graffiti creations can be easily removed with a stiff brush. Anti-graffiti treatment is functional coating, in contrast to conventional anti-graffiti coating, breathable.

4. Ability to use the image “environmental construction” for self-promotion
Activated treated area functional coating cleans the air of particles and microscopic particles of hazardous substances with which they can not deal with any other technology. Collision of these substances dispersed in air, surface active functional leads to rapid removal of the effective distribution of particles mainly H ₂ O and CO ₂ , 10 m square facade treated with a photosensitive coating is functional in the state (without any energy and maintenance costs) per year to cleanse the area where the building stands, approx. 30 million cubic meters of air from harmful pollutants from transport district heating and industrial production!

The application and maintenance of
functional coatings are aqueous suspensions photosensitive titanium oxide (TiO ₂ ) and other minerals. They are used as a topcoat.Packages are not washable. Creating a functional layer is completely inert and breathable.
Suitable substrates are :. spout, unglazed clay bricks and tiles, rough stone, silicate and acrylic plaster and paint, lime stucco
average consumption of functional coating suspension is 1 l to create 10 m ² PHOTOCATALYTIC surface (this might vary depending on the absorbency and structure of the substrate). The photocatalytic surface is formed by using another two or three coating layers, a new layer may be applied after drying of the previous layer. Damaged photocatalytic surface can easily restore a new coat of paint. treated with a functional coating that remains clean and neporůstá fungi, algae and lichens and mosses area. It does not require maintenance. If no mechanical removal of the functional layer or the imposition of any other material in theory, is not life and functionality of the time limit. In the external environment, but Erosion occurs due to wind and rain, the gradual abrasion. The manufacturer recommends to restore effectiveness of one of the surface layer of the photosensitive coating for 10-15 years on the vertical surfaces, and after 5-7 years conical surfaces that are more exposed to the erosive effects of water and snow.
