ABSTRACT
On some surfaces plaster protects the walls. They are made with different mixtures for the inner and outer surfaces. Their composition for the internal surface is made of a part of lime, a part of fine sand and for the external ones is made of a part of fine earth, a part of lime and two parts of sand. The use of lime makes them more resistant to wind and rain. Lime was also used within the rammed earth in order to make the edges stronger.
