Definition
Overspray is the excess paint or coating that does not adhere to the intended surface during a spraying process. Instead, it becomes airborne and can settle on surrounding surfaces or remain suspended in the air.
How It Happens
Overspray occurs when paint particles are not properly controlled during application. Common causes include:
Incorrect spray technique Poor airflow control Improper equipment settings Excessive spray pressure Why It Matters
Overspray can significantly impact production and safety:
Material Waste: Increases paint consumption and cost Poor Finish Quality: Leads to uneven coatings or contamination Health Risks: Airborne particles can be harmful to workers Environmental Impact: Contributes to pollution and VOC emissions How to Reduce Overspray Use properly designed spray booths Optimize airflow and ventilation Adjust spray equipment settings Train operators on correct techniques Use high-efficiency spray systems (e.g., HVLP) Related Terms Spray Booth VOC Filtration System Airflow HVLP Spray
