Pfannen zu giessen und dann die Betonsteine gegen die Flüssigkeitsoberfläche zu pressen. Um ein glattes   Ablösen des Steinesmitsamt dem Überzugbeim Herausnehmen aus der Pfanne zu gewährleisten,wirdvor-    teilhaft ein Ablösungsmittel verwendet, das ein Haften des Belages an der Pfanne verhindert. Dieses Mit- teil ist von grösster Wichtigkeit, da jedes Ankleben des Belages die Oberfläche des fertig überzogenen   i Bauelementes beeinträchtigt. Es   wurde gefunden, dass ein organisches Polysiloxan,   z. B. Dimemylsiloxan,   wenn es mit Erdölfraktionen verschnitten ist, sich hervorragend für diesen Zweck eignet.

   Beispielsweise können   5%   Dimethylpolysiloxan und   95%   einer Petroleumfraktion wie   z. B.   das als Hysol 70 bekÅannte   "Naphtha"des   Handels verwendet werden. Werden die Pfannen mit einem derartigen Ablösungsmittel be- sprüht, löst sich nachher die Überzugsmischung tadellos von der Pfanne ab. 



  Nachstehend wird beispielsweise eine bevorzugte Zusammensetzung einer erfindungsgemäss verwend- baren   Überzugsmischung,   ausreichend für die Herstellung von   265 I,   angeführt.

Pouring pans and then pressing the concrete blocks against the surface of the liquid. In order to ensure smooth detachment of the stone together with the coating when it is removed from the pan, a release agent is advantageously used that prevents the covering from sticking to the pan. This communication is of the greatest importance, since every sticking of the covering affects the surface of the finished coated component. It has been found that an organic polysiloxane, e.g. B. Dimemylsiloxane, when blended with petroleum fractions, is ideal for this purpose.

   For example, 5% dimethylpolysiloxane and 95% of a petroleum fraction such as. B. known as Hysol 70 "Naphtha" of the trade can be used. If the pans are sprayed with such a release agent, the coating mixture will then be removed perfectly from the pan.



  For example, a preferred composition of a coating mixture which can be used according to the invention and which is sufficient for the production of 265 I is given below.
