Owner approach of sustainability

The badigeon was the material chosen primarily to reflect what was tradition at the time of the construction of the Cathedral (early 20th century) but also for the need to have a product with great breathability: again due to humidity, it was necessary a breathable material, also to avoid the formation of molds and detachments.

    Badigeon with slaked lime is a natural decorative paint based on slaked lime, for interiors. Available in "pastel" colors (shades of yellow, pink, green, hazelnut), obtained with the use of natural earths.

    BADIGEON is used as a decorative interior paint.
    In the case of restoration interventions, the causes of the existing degradation must always be assessed in advance before intervening to avoid the recurrence of problems previously encountered; in particular, it is necessary to eliminate or reduce the phenomena of humidity due to capillary rising, the possible presence of salts and the phenomena that may occur on external facades due to poor protection from atmospheric agents.

    Thanks to its naturalness, it is a product that is attentive to the health and safeguarding of the individual and the environment.

    • Vases of 18 kg approx.
    With BADIGEON there is no guarantee of a completely uniform coloring, typical of acrylic paints, since the characteristic of lime-based products is to take on slight chromatic variations, determined mainly by the different drying conditions of the product.

Urban environment

Environmentally integrated design in the urban context of Nice.

Reasons for participating in the competition(s)

The Orthodox Cathedral of Saint Nicholas in Nice is the largest European Orthodox church outside the borders of Russia: considered one of the "jewels" of Russian art, the Cathedral is a treasure chest of incomparable beauty, further enhanced by the conservative restoration project completed at the beginning of 2016, after about two years of construction.

In dealing with the restoration of the Cathedral, thanks to the richness and multiplicity of materials and techniques present, a challenging design and operational path was created which saw the interdisciplinary contribution of Italian architects, historians, restorers, geologists and chemists and French.

This important conservative restoration project has been studied by applying Italian methodologies and materials contextualized to the existing building, maintaining the Italian tradition of conservation and restoration through the search for quality characteristics that allowed to create targeted paths.

Morandi Bortot , a company that has been on the market for over a century, is one of the realities? among the most? influential in the world of natural lime: in the conservative restoration project of the Cathedral of Saint Nicholas in Nice, the Treviso company was in charge of supplying the material for some of the restoration work.

Do we find a sign of the company's responsible vision also in the choices that have maintained a low environmental impact of the production systems, in line with the total naturalness? of the product obtained.
