Our concrete colorant dust is an economical way to turn boring gray concrete into natural looking stone. Begin by spraying a very light mist of water into the mold. Then simply dust a very light layer of the colorant inside the mold. A flour sifter works well. If you don't have one than you can punch tiny nail holes into the steel lid of an old jar and shake the dust throughout the mold. Just make certain that the holes are not to large.
For the best result of natural looking stone, dust two three colors into each mold cavity.
