The method involves treating surface area of a negative coagulating mold section (24) with treatment media. Silicone-based treatment media e.g. silicone-based oil such as silicone oil and/or paraffin oil, are applied to the surface area during treatment of the surface area. The treatment media are designed as a mixture of wax e.g. Vaseline(RTM: Petroleum jelly), and a thickener, where the thickener is formed as a crushed or pulverized solid e.g. gypsum, cement and/or stone dust. The mold section is partially made of a porous and/or absorbent material e.g. foamed plastic. An independent claim is also included for a method for producing concrete elements. |
