Technical requirements for renovation plasters are specified in the WTA guideline "Renovation mortar systems". Systems of renovation mortars are generally composed of a splatter dash plaster, sometimes a base plaster, the actual renovation plaster, and a top layer or a coat of paint. These materials have to be tuned with respect to each another. Test methods and measurements for quality assurance are described and details of the processing are explained. The WTA certification process for renovation mortar systems is described. Some problems of planning and processing are also discussed.
