How far should my I hold the nozzle on my ESS spraywand from the targeted object?

As in painting, the goal is to achieve even coverage over the surface. The Spraywand is designed to help do just that. By propelling the chemical spray with a gentle air flow, you can stay well away from the target surface and let the electrostatic attraction do the rest of the work. The optimal spraying distance is at least 24 inches away from the target surface, however 34 to 36 inches may provide a more even coating.
