What does overspray refer to in painting?

Overspray refers specifically to unintended paint particles that become airborne during the spraying process and land on surfaces other than the intended target. This phenomenon occurs when paint is atomized and propelled into the air, which can lead to unwanted splotches or coloration on nearby objects, surfaces, or areas not intended to be painted. This can compromise the finish quality and require additional cleanup or touch-up work.

The other options do not accurately capture the definition of overspray. Uneven drying is related more to application technique or environmental factors rather than the overspray itself. Excessive use of thinner affects the consistency and application of the paint but is not directly related to overspray. Paint drips occur when paint runs down surfaces, often from an excess application or poor technique, rather than from particles drifting through the air. Understanding overspray is crucial for maintaining quality and precision in painting projects.
