Work instructions
Add the dry material to the water and mix with a power mixer or a drill paddle for approximately four to five minutes. Allow the mixture to stand for approximately ten minutes and mix it again for a short while. By remixing, the correct plasticity of the mortar is sought by adding the final amount of water. It is not recommended to add the maximum amount of water right at the start.
After treatment
The plaster binds chemically in room temperature and ceramically at a temperature of appr. +700°C. Before the structure is brought into use, it is allowed to dry for 2 to 3 weeks with the hatches and dampers open. The first heating is performed carefully with a fan heater, for example. Heating is continued for the subsequent 3 to 5 days with a constant small fire. The hatches and dampers are left open after each drying heating.
