Last week Tom and I went to West Texas, near Presidio, to work on an adobe building, the same one I was working on last fall. We worked on the Nubian vault for the new office building, and we re-plastered the house. The workshop was organized by the Adobe Alliance.
Traditional adobe buildings require re-plastering on a regular basis. This house had not been re-plastered in several years, and torrential rains and hail last fall had damaged the plaster and stripped a lot of it off.
Here you can see the end wall, and the unique angle at which the adobes are laid up to form the vault, when making an adobe Nubian vault.
Tom and I got there on the second day of the workshop. The other workers had spent the previous day testing some adobe samples, with different mixes of sand, clay, straw, and prickly pear juice.
The photograph below shows how the domed guest house. You can see how the rains have washed away the plaster on the windward side.
The plaster workers began re-plastering on the parapet of the house.
By the end of the day, the plaster crew had finished re-plastering the parapet, and they had started on one of the vaults.
Meanwhile, the vault crew was attempting to erect a scaffold to fit under the vault in progress.
Still, we got a few new courses up on the vault.
