Concrete requires at best a few dry days. If you are attempting to DIY give all product instructions a good read prior to starting your Project.
MARBLE EFFECTS FOR CONCRETE PAVING - WHY BE BORING?
By Joan Kamaru
We recently had to repaint a small area of concrete paving. Our local paint store offered us an acrylic paint product for paving that held foot traffic only. It was a lovely ochre color, very nice.
I normally make decorative Finishes for Walls, Ornate Plaster and other substrates found around the Home. My outlook on painting is that if an effect can be employed why be boring? I had a sudden urge to try out my Marble Techniques with the newly purchased Paving Paint.
Marble!!? Well, why not!

Here is how I Marble with Paving Paints on a clean or fresh paving surface:
(White) Marble Effects
Purchase acrylic White Paving Paint and a Grey or Black Tinter(never use more than 10% Tint) to create your effects. If Tinter is not available buy another tin of paint that is tinted in the appropriate colors for your Project. Acrylic Paint dries very fast and has little odor to it. The clean up is easier as well. Enamels take forever to dry and the fumes are too much for me, but they can be used and are hardier.
Pick a dry sunny day to paint!
Lay down a first coat in a Base Color using a wide flat brush. You can use a roller for larger areas.
Base Color: For example if you want white marble with grey streaks start with a lightly tinted white paint. Pure white is hard and looks better when softened with a small amount of Tint or Tinted Paint. Let this dry according to the manufacturers instructions found on the can.
Concrete is fairly rough in that it has tiny holes and cracks. Work the paint into the concrete and go for an even coat spread over the area you are decorating. Start by painting around the edges and work your way in. If it is an Entrance, make sure there is another way in and out to direct traffic until the Project has had a chance to dry.
Now you will start applying decorative paint. Try out each step on a separate board until you get the hang of it!
Carefully mix an amount of paint/tint to get the color you want and keep it aside. Using only a small amount each time, pour into your container/pot as you need it. You want to make enough to cover the whole area. If you make too much that is fine as you will mix it in the next batch. If you don't make enough it will look awful and patchy.
Use a rag made from toweling or other strong fibers. I used a toweling floor mat from the bathroom. It is the right size and strength. Scrunch it into a ball that can be easily held in your hand. I use an old pot to mix the paint used in this step. Lightly dip your rag into the mixture in your pot and blot onto a trial board prior to blotting the pavement. Blot the pavement in a decorative way. Do this until the whole area is covered. Step back and monitor your work from time to time. Let this area rest and when dry apply more coats of blotting each time adding Tint or Tinted Paint to the batch. Blot until you have the desired effect.
At this point you might go back and apply a light and sparse coat of white blotting, decorating with a plastic shopping bag (scrunched up). Blend into the marble effect and give it fine highlights.
Some people favor veins, but this is entirely up to you. It is a good idea to find a bit of marble (or whatever you choose to FAUX) that you love and study it closely. Use your example and refer back to it as your Project develops. Take the Sample with you when you purchase the Paving Paint. Veins can be painted on the design by using a fine round brush or a feather.
Another technique is to make a stain and scrub this over the decorated surface but only after all coats have thoroughly dried. This looks great, but do your tests first!
You might also purchase a SLIP RESISTANT ADDITIVE if it is not already in the paint.
The Final Touch is to seal all of this decoration with a clear coat of flooring product. Flooring sealers are usually purchased from a specialist store.

If there is a Trim around the area to painted, give it a base coat prior to decorating and a final coat after decorating.
Good Luck with your Decorating Projects. Please do not hesitate to contact me for any information you might require.
