Here's what you'll need;
2 or 3 different colors of latex paint.
A tinted faux finish glaze.
A sea sponge
A small paint brush
A bucket 1/4 filled with water
A clear acrylic finish (spray or brush on, satin or glossy, your choice)
Start by dipping one end of the sponge in the lighter of your colors. For larger jobs you may want to have a separate sponge for each color. Soak and wring out your sponge first. Your sponge should be damp but not dripping.
After applying a random pattern on your painting surface with the lighter color, use the other side of you sponge to apply the darker color. Be sure to do only as large an area as you can get to before the first color of paint begins to dry. Use the sponge to blend the two colors together on the painting surface. Do not overwork the blending, do just enough until you see a nice soft pattern of lights and darks emerging.
After 30 minutes or so the latex paint should be dry enough to begin painting the cracks and veins. I like to use a sharp flat brush for veining, but some people use liner brushes or even feathers. You may want to thin your paint to make it easier to paint longer lines. Use the same colors you already have and use the pattern you created with the sponges to help decide where to place the lines. howtopage001005.jpg howtopage001003.jpg howtopage001006.jpg
As you create the veins in your marble try to keep it very random with some areas that have dense close veins and some areas that have hardly any at all. Also remember that the veins never dead end. Every vein should continue until it runs off the end of your painting surface or until it meets another vein.
Make some of the lines faint and others heavy. On the heavier lines it looks more realistic sometimes if you paint a lighter line right next to the darker line. Since marble and stone formed in nature has such varied patterns; it's very difficult to make a mistake.
When you really start getting sick of painting veins, you're almost done. A nice touch is to use your brush to fill in a small shape with the lighter color that is outlined by veins in one of the darker areas. If you have some veins or areas that you do not like you can go over them with your sponge again.
At this point you could call it done if you are satisfied with the results. Let it dry overnight and then brush or spray the surface with a clear satin or gloss, this will give it a very nice depth. I like to do one more step though. After all the paint is completely dry again, (at least an hour) take a damp cloth and pour a little of your tinted glaze onto it.
Rub the glaze into the surface with a curved motion. You will feel the glaze begining to set up as you are working it. As you add more glaze and overlap the other areas you just did, lighter and darker areas of glaze will begin to occur naturally. This is a very easy step and doesn't take that long, but the added dimension makes it well worth the effort.
That's it. Let it dry overnight and apply your clear coat. You should end up with something that looks something like this.
All of the colors and techniques presented here can be adjusted and adapted to suit the needs of your particular project. The colors, amount of veining and degree of blending with the sponge are infinitely variable. Here's some examples of different styles of marbling on some columns that I've done.
