Paints

Paint (S), Paints of lime: Term to indicate the mixture of water, lime, Pigments. One also speaks about Peinture to lime, of mineral Peinture Sometimes coloured, sometimes white, thick or transparent, applied to supports of the paint present of incomparable esthetic qualities.

One can classify the lime paints according to their consistency:

Liming

The Chaulage is a mixture of lime and of water in a report/ratio of approximately a volume of lime for a volume of water, relatively thick consistency (especially if one used a lime paste) makes it possible to obtain a painting of thick appearance, stops pore.
The thick character does not make it possible to mix pigments.
This technique " ancestrale" was often used with quicklimes coldly extinct, thus one profited from a " peinture" with the very alkaline character suitable to cleanse the cattle sheds, the walls of farms…

Paint

One increases the volume of water slightly (1 volume of lime for 3 to 5 volumes of water), thus one can add mineral pigments. The capacity coloring of air lime (white) limit saturation color of the paint, it is thus appropriate to limit the quantities of pigment (25% of the maximum lime weight in pigments for the natural grounds, 15% for oxides) Produced mineral painting has a covering aspect, stops pores, the passage of the brush is visible.

Water strong, patina with lime

The volume of water further is increased: Water strong : 1 volume of lime for 6 to 10 volumes of water, produced mineral painting has a transparent aspect, the color is saturated also (60% of the maximum lime weight in pigments for the natural grounds, 30% for oxides) Patina with lime : 1 volume of lime for 30 volumes of water and more, produced mineral painting has a very transparent aspect, These terms are certainly debatable, they however make it possible to associate a vocabulary with techniques which recover same materials for very different results.

Implementation

Paintings with lime require a porous mineral support, ideally a parget of lime. Without being complex these techniques require a good experiment failing this (one is here in the world of the knowledge to make) a hands-on training.
