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:
– Low environmental impact
– Long lasting effects
