The finished surface of the rammed earth was too rough and dusty for the interior of the house so we decided to render them in a light sand-cement mix that is commonly used here to finish and protect the mudbrick houses in the area.
First a key-layer of gravel with bit of earth for binding is applied to the walls. this layer acts as an intermediary between the rammed earth and the sand-cement render: the earth in the mix is able to stick to the walls, while the gravel and texture allow the render to hold on.
All the gaps between the walls and the roof were filled in with stones and earth-gravel mix. this keeps out any unwanted guests (bugs and bats mostly) and helps to further solidify the connection between our wooden bond beams and the walls.
