This is an american book which describes the natural (earth) plaster used to finish new straw bale or rammed earth type houses. It contains a wealth of information on how to mix and apply these finishes and is written in an easy to read way. Photos and drawings are mainly black and white, although there are a few colour photos.
This is not however a book describing the traditional plaster types or techniques used for centuries on european houses. Whilst some of the information contained could certainly be useful for restoration of an old house, this is not really the subject of this book.
