The natural composition made of 60 months aged slaked lime mixed with pigments makes Colourcalce a unique biological paint for indoor usage. Its high breathability (specially if applied on transpirating surfaces) is Colourcalce’s main characteristic along with the quality of being resistant to the weathering of time and UV rays and the capacity of avoiding the growth of any bacterium, mildews and mould. These fine qualities made of Colourcalce the most acclaimed bio paint in the new market of bio architecture. Colourcalce is an indispensable product in the restoring field and in all the applications in use to enrich the building with that veined, solid and recognizable aged look.


Light & dark shadows or nuances are Lime’s aesthetical characteristics. The intensity of the colour depends on the coat’s thickness and on the absorption properties of the wall and its porosity. It is suggested to check the intensity of the coat’s colour once the products is completely dried.
