The degradation that most frequently affects the external walls is the deterioration caused by the smog and the aggression of atmospheric agents. In fact, due to the nesting of dust and soot, stains and black patinas appear on the facades over the years.

This “dirt”, in addition to the walls of buildings, also attacks the other external components of the house such as the terrace and floors, compromising its beauty.

This decay obviously isn’t pretty to see, that’s why we decided to present you in this article, tips and suggestions also for cleaning concrete balconies using the best products to clean external walls.

But let’s start with order and find out what type of smog is most harmful to our walls and how we can act to eliminate it properly.

The smog, which creates black spots and spots on the walls, can be of two types:

  • classic smog: a pollution caused by the action of sulfur dioxide and dust in low insolation conditions, or at the first light of dawn.
  • photochemical smog: caused by nitrogen oxides (NOx), carbon dioxide (CO2), sulfur oxides (SOx), ozone (O3), dust and other volatile organic compounds, under the action of solar radiation.

Naturally the climatic and environmental conditions greatly influence the appearance of the so-called “black crust” on the walls.
Humid environments are enemies of houses. Irreparably, sooner or later, on surfaces more exposed to adverse weather conditions, green or black spots appear due to the formation of algae, mold and moss.
Discovering how to clean the external surfaces from algae, mosses and lichens becomes indispensable to avoid running into problems of neglect and to maintain an adequate decorum of the components that adorn our home.

Thanks to its consistency, PULITORE FC is easy to apply also on vertical surfaces.
The product was applied pure and was left to work for an hour.
Once the cycle was finished, with the help of a pressure washer, the residues were removed and the entire surface was rinsed with water.
As a second step, a strong degreasing-dewaxing wash was performed with an alkaline solvent detergent: SGRISER.
