Wear old clothes!
The best paint to use is spray paint. Premium spray paint works best (such as Rustoleum, example on the right) instead of generic store brands. You will probably need 2-3 cans for a good base coat and additional paint for your design. The quantity needed will depend upon the color you are using, the color already painted on the rock, and weather conditions. Remember, latex paint or paint that is rolled on will take longer to dry.
Once you have the base coat done, use chalk to sketch out your design. Try to do large shapes so that it’s easy to see from a distance and so that you can use spray paint for most of it.
Stand back from the rock to make sure you can see your design clearly.
Spray paint large areas. If you mess up, use the base coat color to fix the mistake.
For more detailed areas, use a can or tube of paint and a paintbrush. While outdoor latex is best, regular artists' acrylic paint seems to work well too (even in rain).
Bring paper towels to wipe any drips.
Bring a cup of water if you are using a paintbrush.
Wearing rubber gloves will help keep hands clean.
No refunds will be issued in the case of bad weather. If wet, the rock can be towel-dried before painting and the paint will adhere even in the rain and or snow.
