Historical plastering – Practical research. August project diary

In August the project team continued practical tests in both Bucharest and Timișoara. Part of the experiments focused on repairs to an existing plaster of similar type, which, according to laboratory results, would be based on Parker cement – a type of cement that appeared in the early 19th century, obtained by burning at up to 950°-1000°C. The tests took place in Timișoara at the István Nemes Palace, designed by arch. Lipót Baumhorn in 1902. With the support of Prof. Dr. Johannes Weber from the University of Applied Arts in Vienna, the project team received two types of Parker cement for experimentation, one made in Poland, the other in Spain, used for the restoration of modernist buildings.

A second direction of research has been the cleaning of symphyte surfaces of dirt deposited over time or organic deposits (mosses and lichens grown over time). Mechanical cleaning (from knife or brush removal to dry or wet blasting) and chemical cleaning (by testing Remmers products) were observed.

Research is currently focused on understanding and analysing laboratory results in the context of practical observations and formulating initial conclusions and recommendations for the conservation of facade textures.
