The Association has produced a brochure to remind people of the need to use traditional all-lime mortars and renders when renovating old buildings. Lime allows stone to breathe, unlike commercial coatings whose chemical composition traps moisture, a source of disorders.

These renderings can also be applied to new or recent buildings, and their patina will quickly become recognizable, unlike chemical renderings or renderings with a low percentage of lime, which do not develop a patina but become dirty. Façade detail: the rendering comes to rest on the stone surrounds.

These coatings can also be applied on new or recent constructions, their patina will be quickly recognizable, unlike chemical coatings or those with only a small proportion of lime, which do not acquire a patina but rather become uniformly dirty. Facade detail: the plaster comes to die on the framing stones.

Compare the rendering on the "5" (chemical) with that on the Maison de la Truffe (100% traditional lime, which is certainly several years old...) The difference is obvious, and the former will never develop the same patina as the latter.

The village's classification as a Site Patrimonial Remarquable (July 2019) now requires the use of natural lime coatings.
