Exterior Earthen Plaster: Abiquiu, NM
In September 2016 I spent a week applying an exterior earthen plaster base coat to a small (privately owned) adobe chapel in Abiquiu, NM. The adobe walls had been left unplastered for 5 years so the mortar joints were quite worn. A large amount of material (and arm strength) was needed to fill the joints and cover the walls with a consistent coat of plaster. We added asphalt emulsion to the mix to make the plaster more water resistant. The natural red color of the soil we used for the plaster mix is typical for the Abiquiu area. A finish earthen plaster coat will be added in 2017.
Key education takeaways:
- sourcing clay soil in the Abiquiu, NM area
- sourcing suitable plaster aggregates in the Abiquiu, NM area
- on-site straw shredding
- stabilizing earthen plaster with asphalt emulsion
