Natural plastering are beautiful and non toxic to live with. It is steeped in deep tradition worldwide.
The work of natural plastering today is taking millennia-old techniques and materials and combining them with contemporary materials and tools. Implementing them safely and efficiently in a modern construction.
Advantages of the natural plastering
Hemp lime is a renewably sourced material, hemp lime is composed of hemp shiv, lime binders and water. working with plant materials brings environmental ethical, social and economic advantages.
Hemp production offers an excellent opportunity where basically all parts of the plant can be used.
In fact the plant has great advantages for being cultivating because it also has a rapid growth, low water consumption and limited parasitic attacks.
It is an innovate and environmentally friendly material, which makes buildings more energy-efficient, healthier and more comfortable.
It is more than the simple sum up of two materials and in fact it is a new bio composite in which the lime gains the insulating properties and the lightness of geo mineralized hemp.
Good thermal insulation properties offering thermal benefits throughout life.
Lime Plaster - Intonachino
Lime plaster is a type of plaster composed of sand, water and lime. Lime plaster was found to have been a multi-purpose material at the archaeological site of Ain Ghazal in the modern day of Jordan. The archaeological site shows sign of settlements from 7200 BC to 5000 BC.
Lime plaster are more “plastic” and better accommodate any settling or movement in the wall than cements, which do not adjust to changes -movements once the cement are made.
Although lime plasters are more breathable, they also have better water shedding characteristics.
Instead cement is most likely to crack under stress or movement, allowing a route for water inﬁltration into the interior where it will be trapped.
In contrast, the lime stucco can be adjusted to every early movements in the building because it does not set fully all the way immediately, but only as the interior more slowly carbonates.
A Phoenician technique used by the Romans whom called it the Opus signinum. A latin term that Vitruvius described in the procedures and ingredients for making coatings, aqueducts, cisterns and roads. The cocciopesto material composed of dust obtained from bricks, tiles and roof tiles. The materials are crushed in different grain sizes. Particularly suitable for humid environments due to the high breathability and hygrometric capacity of terracotta and lime.
This stucco was the first important ancient Roman plastering.
The Romans discovered that by combining lime with the Terra di Pozzuoli (today pozzolana), an earth containing a large percentage of clay, they could obtain hydraulic lime. This type of lime hardens even underwater. This allowed them to build in the midst of rivers and in presence of large quantities of water and humidity. The Cocciopesto color is usually composed of two distinct shades, red, yellow with different tones that depend on the cooked clay. Or by adding oxides or natural colored earths. While the specific processing is done by hand by mixing the various mixtures. However, infinite possibilities allows creating fascinating and undoubtedly inimitable spaces.
