What is the minimum stroke overlap in spray painting?

• A. 25 percent
• B. 50 percent
• C. 75 percent
• D. 100 percent

Answer: (B)

In spray painting, each new pass should cover roughly half of the area painted in the previous pass. So the minimum stroke overlap is fifty percent. This overlap helps ensure an even, continuous coat because spray patterns aren’t perfectly even and there can be drift or gaps between passes. If you use less overlap, you risk thin spots or visible gaps; more overlap—like seventy-five or a full hundred percent—can lead to heavy buildup and runs. Starting at about 50% and adjusting for your spray pattern, distance, and material is a practical approach.
