smog1Pollution, and especially particulate matter, is the main cause of deterioration of the construction and finishing elements located in the facades of buildings.

The airborne substances to which the materials are exposed and the climatic conditions, act on the supports modifying their composition. In this case the degradation takes the name of “chemical degradation”.

The most common effects of smog on materials are:
– Formation of Black Crusts
– Surface backwardness (chemical dissolution)


The first operation to be carried out in the presence of chemical alterations is the complete cleaning of the surface and the removal of smog crusts, if any. For this operation it is possible to intervene with various types of procedures and products: chemical or physical systems.

For the cleaning of materials CIR proposes the use of chemical systems made up of specific cleaners, with variable PH, compatible with the chemical nature of the supports, able to guarantee the respect of the material, of the operator and of the outdoor environment, thanks to the biodegradable surfactants contained within them.

Subsequently it will be necessary to proceed with a specific protection and antismog; the particularly active principles contained within the formulations studied by CIR allow to strongly limit the penetration of the smog particles, transported by water and not, inside the porous materials, thus making the surfaces easy to clean.

Requirements necessary in this area of application:
– Effectiveness
– Compatibility
– Low environmental impact
– Long lasting effects

  • Wet the substrate with clean water
  • Apply the specific “RP” cleaner making it foam
  • Wait from 5 to 15 minutes
  • Risciacquare con abbondante acqua a pressione controllata
  • Then proceed on a dry surface with the application of the specific protective layer NO SMOGo PTO 10
The solution proposed by CIR allows to act on all types of materials used in the facade, removing the smog patinas in a selective way, without causing damage to the material.

The possibility to dilute the cleaners according to the needs, allows to intervene gradually, thus avoiding damaging the materials, keeping the natural aging patina of the supports unaltered.

Furthermore, the anti-smog protectives, in addition to specifically limit the degrading action due to chemical alterations, give the materials a high water-repellent power, necessary to guarantee the total protection of the material.

During the cleaning phase it is essential to wet the substrate with water, before applying the cleaner, so as to allow the product to act on the smog patina outside the support, limiting its penetration into the porosity of the material.
