The process consists in extending, over a vertical or horizontal surface, one or more successive layers of a previously prepared paste based on cement and additives, in which are printed, by means of a mould, specific forms and contours. The improvements are characterized in that the aforesaid printing is achieved by means of a mould of cylindrical configuration, which can rotate freely. This mould is displaced over the surface to be printed along parallel, consecutive strips. The intensity of the printing or engraving (drawing) is obtained by means of the mould's weight.
