It is important to mix the components very carefully, therefore it is useful to work with a pestle and mortar to mix the fillers and the final filling mass. First the binding media should be mixed thoroughly, then the filler mixture is added and mixed until a soft homogeneous mass is obtained that does not stick to the mortar.
