This method relies on a non-woven fabric for a controlled release of a solvent targeted to clean sensitive surfaces and cultural heritage.
The restorer simply places the fabric on the surface to be treated, making it adhere and waiting for a few minutes: in this way the solvent interacts with the layer to be removed, it swells and is incorporated into the fabric itself. At the end of this process, the restorer removes the non-woven fabric from the surface, which remains free of paint without residues.
ADVANTAGES:
- Less use of solvent, with consequent economic and environmental benefits.
- Simplification and effectiveness of the cleaning system.
- Reduction of the risk of damage to the cultural / artistic asset.
- Limited exposure to solvents
FIELDS OF APPLICATION:
The application sector is that of the restoration of cultural heritage, such as:
- polychrome works
- sculptures
- archaeological finds
- archival material
- cinematographic films
