Problem
consolidamento1The multiple degrading actions on natural surfaces, caused by chemical or physical alterations or by microorganisms, can cause on the material itself a loss of binder, such as to make the surface weak, crumbling and incompact, with increased porosity and losses of material.

The stone materials are also rigid and fragile, so they are sensitive to outdoor and indoor mechanical stresses (loads, vibrations, frost, crystallization of the salts, thermal expansion).

When this happens, the surface needs a conservative consolidation intervention, as well as initial cleaning and subsequent protection.

Solution
The consolidation of porous materials is intended to interrupt the progress of degradation, returning the lost compactness to the stone or to the artefact.

In conservative interventions of stone materials, the products used for the consolidating treatment must be able to:

  • Recreate the continuity between the deteriorated layers and the healthy core of the material
  • Improve the resistance to mechanical efforts applied both outside and inside the capillary network
  • Ensure the reabsorption of stress strains caused by thermal cycles

INTERVENTION CYCLE

  • Removal of pollutants present on surfaces with a specific CIR cleaner
  • On a clean and dry surface, carry out the consolidation intervention with the application of one of: ACQUACONSCONSACRIL SIL ACONSACRIL SIL S
  • Evaluate the consolidating effect after a few days and repeat the operation if necessary
  • Apply the specific CIR protection on a clean and dry surface

N.B. In the case of consolidation with CONSACRIL SIL A and CONSACRIL SIL S the final protective does not need to be applied.

ADVANTAGES OF CIR SOLUTION
CIR uses molecules that form intermediates as close as possible to the natural binder of the stone. These molecules can be organic or inorganic in nature and present substantial differences between them: water repellence, guaranteed only by organic ones, and chemical affinity with the treated materials.

The SOLUTION proposed by CIR have the following advantages:

  • IT IS NOT SUBJECT TO QUICK AGING
  • IT HAS A GOOD RESISTANCE TO CLIMATE CONDITIONS
  • IT IS COMPATIBLE WITH THE CHEMICAL AND PHYSICAL PROPERTIES OF MATERIALS
  • IT GUARANTEES VAPOR PERMEABILITY
  • IT DOES NOT CAUSE HARMFUL BY-PRODUCTS
  • IT IS NON-TOXIC AND ECO FRIENDLY
THE TECHNICIAN RECOMMENDS
To obtain a good result of consolidation, it is necessary to evaluate the absorption of the material, in order to choose the right dilution of the consolidant and to intervene in depth.
