Which practice helps prevent overspray during painting?

• A. Proper masking and spray technique
• B. Rough surface preparation
• C. Using thicker coats
• D. Increasing spray speed

Answer: (A)

Controlling overspray comes from masking off areas you don’t want painted and using a spray technique that keeps the paint on the intended surface. Masking creates physical barriers so paint won’t reach edges, trims, or nearby panels, which is the first line of defense against unwanted coverage. The spray technique part involves factors like distance, angle, motion, and trigger control. Holding the spray gun at a consistent distance (a typical range is around 6–8 inches, adjusted for your setup), keeping a steady angle, and making smooth, overlapping passes with even, gradual trigger pulls help produce a uniform film and minimize paint that drifts beyond the target area. In other words, good masking plus disciplined technique prevents paint from escaping the intended area and reduces overspray. Rough surface preparation is about how the surface accepts paint, not where the paint goes. Using thicker coats increases the amount of paint and can lead to runs and more overspray. Increasing spray speed reduces control and can push more paint off-target, increasing overspray.
