THE PROBLEM

The airborne substances to which the materials are exposed and the climatic conditions act on the supports by changing their composition; in this case degradation is called chemical degradation. The most common effects of smog on materials are: formation of black crusts, surface withdrawal (chemical dissolution), crystallization of salts.

The level of aggression and the mechanism of alteration due to pollutants, however, vary depending on theexposure of the material,the chemical nature of the material and the external environmental conditions.

THE SOLUTION

The first operation to be performed is the complete cleaning of the surface and removal of the smog crusts. For this purpose, CIR proposes the use of chemical systems consisting of specific detergents,with broad PH range,compatible with the chemical nature of the supports and able to ensure respect for the material, the operator and the external environment,thanks to the biodegradable surfactants contained within them.

Subsequently, it will be necessary to proceed with a specific protection with anti-smog effect: the particular active ingredients contained within the formulations studied by CIR allow to strongly limit the penetration of smog particles,thus making the surfaces easy to clean.

OUR TECHNICIAN RECOMMENDS

In the cleaning phase it is essential to wet the support with water, before applying the detergent, so that the product can act on the patina of smog outside the support, limiting its penetration inside the porosity of the material.
