ABSTRACT:
A method of making a cast concrete stepping stone whose exposed upper surface has the appearance of two or more grouted attractive natural stepping stones. A liquid release agent is applied to the mold which is then placed on a vibrator table and filled with wet concrete. The mold is vibrated for about 30 seconds and the surface of the concrete troweled smooth. Dry body color is sprinkled over the concrete surface and troweled to completely cover the concrete. A dry release agent containing powdered color having a darker shade than the body color is sprinkled over the dry body color covering the concrete. The desired pattern is then pressed into the surface of the concrete and after a six hour drying time, the cast stepping stone is removed from the mold. Excess body color and release agent are washed away and the washed surfaces totally dried. Finally a clear concrete sealer is applied to the exposed upper surface of the concrete stepping stone.
