a two layered plaster design was chosen. The first aspect of our design is a base coat made of one part clay and soil, one part sand and one part sawdust. This layer is applied relatively heavily to reshape the bench in minor ways and to fill in holes and cracks from wear and tear. The fill coat also provides a clean smooth surface to apply a finish coat to. Out of twenty eight samples that we tested this mixture held up the best.

The second coat was applied for both aesthetic purposes and to provide long lasting durability. This plaster mixture uses a ratio of 1 part mixed hydrated lime and water to three parts sand. This mixture is similar to one used by CCAT before, and it is recommended in Earthen Building.
