For interior and exterior walls: preparing mortar, plastering walls, designing surfaces. Clay and lime are environmentally friendly and valuable building materials that are also available regionally. For years, they have been increasingly used again. The two authors, who are well-acquainted with the practice, detail which plaster structure is appropriate for each application and how to produce and process clay and lime plaster mortars. The treatment and maintenance of surfaces, as well as the design of plaster surfaces through structuring, smoothing, coloring, and decorative elements, are also clearly presented. Many photos and drawings document the various plastering techniques, showcase completed projects, and provide inspiration for designing your own living space. The book is aimed at anyone who wants to work with natural building materials like clay and lime for plastering.
