Applying clay plaster may be one of the most satisfying parts of building a natural home. Smoothing over cob or straw bale walls with a creamy clay plaster mix is incredibly satisfying and brings about a truly dramatic transformation. What was once coarse is made buttery and gracefully smooth. For a successful clay plaster job, it’s important to carefully prepare and mix your material. In this post, I will explain the preparation methods and recipe I use for most of my natural building work.
The past three days I have been busy applying finish earthen plaster to the interior of my cob house. I expect it will be done tomorrow. Here are a few photos of the plaster work in progress, along with some of the mosaics that are being installed underneath the rafters of the reciprocal roof.
A few days ago, Tamar suggested that perhaps I’d want to do a mosaic on the outside of my house. I’d been doing the exterior earthen plaster and was nearly complete, and I had only a small portion of wall remaining near the entryway. I took her up on the offer.
A week or so ago, while the weather was still reasonably comfortable, I decided to experiment with making an earthen finish plaster. I settled on ingredients and a recipe for my earthen plaster mix relatively easily after talking to others who have done plastering here at Dancing Rabbit in the past.
