Earthen Plasters - Part 1
There are as many varieties of earthen plaster as there are soils to make them with. As with all methods of earthen building, every soil, and therefore every plaster is different. Different types of clay have different strengths and weaknesses, different minerals create different colors and soils have different amounts of clay in them.
The main ingredients that make up an earthen plaster are soil with some amount of clay in it, and either an aggregate or fiber (most often both) that keeps the clay from cracking. There are many things one can add to an earthen plaster to make it stronger, or a different color, or any variety of qualities you may want to achieve with your plaster.
What is Natural Building?
Natural Building involves a range of building systems and techniques that prioritize the use of minimally processed, locally available, abundant and renewable materials. Natural building walls systems are going to look different depending on where you are in the world, who is building the structure, and what the needs are of the building once it is done.
