The studied ceiling plasters were sampled the Mistr Jan Hus Church in Česká Lípa. The material consisted of several layers of paint. The aim of this research was to characterize the individual layers of plaster in the Stauss system.

Analysis of the plaster layers sampled from the ceiling of the hall at the Jezeří chateau (CR). Using the instrumental methods SEM-EDS, TGA/ DSC and by dissolving the material with HCl acid), the individual components of the material were determined and the composition of the individual layers of the layers was described. The core layer of the plaster is formed by the aggregate mainly based on quartz grains, the secondary component is feldspar. The grain size of the aggregate part is up to 8 mm. The aggregate makes up 69% by weight. The binder of the plaster is hydraulic lime, medium to strongly hydraulic. The top, stucco layer is 5-7 mm thick. The composition is similar to the core layer, only the grain size of the aggregate is smaller - there are grains up to 0.5 mm in size. On the surface of the stucco layer is a lime microlayer (paint) with a thickness of 70 µm. The binder of this surface micro-layer (paint) is the air lime.
