Let's assume the sketches have been approved and the surface has been prepared for painting. To begin I draw the initial outline with a light color.

Traditional muralists will begin by gridding out the entire wall, in proportion to the sketch. That step can add several days to the process. They also do the first outline in charcoal, which requires a clear coat or immediate painting (with no rain). Graffiti writers don't have such luxury when risking arrest. We quickly develop the skill to transfer the sketch freehand.

You can see the lettering behind the character in two colors. Initially in yellow I spaced it out on the wall. Then in green I fleshed out the shapes.

Once I have all my outlines in place I begin filling in solid areas.

I fill in the colors of the letters. Every large area must be painted before going into tight detailed areas. This prevents over-spray on the detailed areas.

Next I begin the character. I always start with the eyes and work outwards.

I want to draw more attention to the face so I change the arrow on the helmet to white. At this stage I'm detailing the entire character loosely.

Outlining is one of the last things to do. Then comes highlights, shines, and lastly a signature.

Some murals will require a clear coat for protection against the environment. This process involves 1-3 days drying time for the mural and one day for clear coating.

Here's the finished mural.

These photographs were taken by this family. Total painting time was about 5 hours.
