How much overlap (%) is required for hand-held spray guns?

• A. 100%
• B. 50%
• C. 75%
• D. 25%

Answer: (A)

Hand-held spray guns require full, 100% overlap to ensure uniform coverage. The spray pattern from a wand can vary a lot because of distance to the target, angle, speed of movement, nozzle type, and wind. If you don’t overlap completely, small gaps can be left between passes, leading to untreated areas. By aiming for complete overlap, each pass covers the area sprayed previously and fills any minor gaps, giving consistent coverage across the entire surface. Lower overlap levels (25%, 50%, 75%) risk gaps unless you’re perfectly precise in distance and motion, which is hard to achieve with a handheld sprayer.
