Historic buildings are more closely tied to the ground than modern buildings. They are more porous, take water from the ground, transport it through their structure and evacuate it, generating side effects such as oxidation and crumbling. Walls and floors are the point of exchange for these reactions. An increase in the soil moisture could lead to a greater circulation of dissolved salts, and therefore to a harmful crystallization on the decorated surfaces but also to a greater instability of the soil. Our objective in this work is the choice of a plaster coating to limit damage due to climatic factors and mainly humidity. We are characterized the coating compositions firstly, and then proposed plaster based formulations. The choice of the best plank may be made by carrying out Karsten tube penetration and capillary absorption tests.
