Dear adobe friends,

The next online class I am teaching for Adobe in Action - Interior and Exterior Plastering - begins on Monday, September 1, 2014. Earthen plasters are a great way to finish just about any wall substrate in the home. They create a soft, breathable final plaster layer which regulates humidity, odors and sounds like no other wall finish can. Plastering is a great way to get a feeling for building with earthen materials because the thin plaster surfaces give us direct and immediate feedback on how well we've selected and mixed our clay and aggregate materials. Also, you can practice your earthen plastering skills over existing conventional walls if you wish. We'll show you how!
