A natural wash of the organic coated surfaces by atmospheric rainfall shall normally be assured in order to prevent any clogging that may be detrimental to their appearance (dust deposits etc).

For walls and roof surfaces that are not naturally washed by rainfall, regular maintenance is compulsory, with the following minimum frequency:
- An annual washing without the use of abrasive or aggressive products;
- Systematic and immediate treatment of any parts that, for various reasons, show initial signs of corrosion.
