At the end of the Middle Ages, the stone is first used, then the mud wood structures give way to the brick and plaster or lime band lines.
The modern period (twentieth century) brings new constructive technologies and new materials (cement and all its variations). With the industrialization of construction, and to meet the growing needs, the coatings were manufactured by the manufacturers imposing a uniform composition ignoring the local peculiarities: the cement reigned supreme at the expense of lime renders, imposing in the consumer's mind a degraded image of lime.
When restoring or building the plaster, it is important to keep in mind that:
Coating is a factor of regional identification by its color and texture
The coating must be composed with materials according to its climate
|Façade Niçoise||Maison Bretonne||Les typiques de Roussillon en Provence|
-In the north, in Normandy and Picardy, we favor light colors. The facades are often white or slightly creamy but sometimes very bright red (reminder of the brick) in the North and Picardy.
-In Aquitaine and Midi-Pyrénées, we allow ourselves some fantasies: bright red and dark green of the Basque Country through the pink Toulouse, white saffron yellow in the Tarn to gray. The colors are varied and far from sad.
-In Auvergne and Limousin, the colors of natural stones are preferred. The facades are grayed out. Towards the south of the limousine, the hues are lighter, and pull towards the pink in the Creuse.
-In Brittany, we find all the palette of gray in reminder of granite. In Pays de Loire the tuffeau makes the facades clearer and white. While in Charente we find brick, pink granite and rammed earth that diversifies the colors.
-Ile de France, Champagne, center: from white to ocher in Ile de France with chocolate tones in Paris. The colors are more golden in Champagne.
-Alsace, Lorraine, Ardennes: we find shades of red, yellow and green coexisting with natural wood.
-Influenced by mud and clay, the colors of the façades of the Rhone Valley, Burgundy and the Alps offer a beautiful range of ochres for the Savoy, the gray of the stone of the Alps, to moles taupes plaster of Burgundy.
-In the south: Provence, Languedoc, Roussillon, the Ocher coating reigns supreme and offers a palette of shades ranging from golden sand, to Provençal pink through the orange and red hues.
The coating can be realized with a mortar "bastard" which is a mixture of air lime and hydraulic binder + sand + water.
or with lime mortar without addition of hydraulic binder and in which case, it will not be suitable for the basement and it will have to be protected with a tarpaulin of rain, sun and wind for several days. This mortar will be formulated as follows:
1) Gobetis: 1 volume of air lime + 2 volumes of sand (0 to 5 mm) + water - thickness of 5 mm
2) Dressing: 1 volume of air lime + 2.5 volumes of sand (0 to 3 mm) - 10 mm thickness
3) Finishing: 1 volume of air lime + pigment (from 1 to 10% relative to the weight of the lime) + 2.5 to 3 volumes of sand + water - thickness of 5 mm
Attention: between dressage and finishing, it will take about 3 weeks.
