Overspray is the fine mist of paint that drifts past the target area during spraying and settles on nearby surfaces. Proper masking and drop cloths keep it off windows, vehicles, and landscaping, and it’s the main reason spraying takes more setup than brushing.
Wind turns overspray into a bigger problem, which is why we check conditions before spraying exteriors and add extra shielding on breezy days. The setup time is the price of the smooth, fast finish spraying delivers.
