How can a technician prevent overspray during the painting process?

Using proper masking techniques and air pressure adjustments is essential for preventing overspray during the painting process. Proper masking involves covering areas that should not receive paint with appropriate materials, such as masking tape and paper or plastic sheeting. This creates a defined boundary that helps contain the paint within the desired area and protects adjacent surfaces from unintended overspray.

In addition, adjusting air pressure on the spray equipment allows the technician to control the atomization of the paint. Lowering the air pressure can reduce the speed and distance the paint particles travel, thereby minimizing overspray while maintaining a good finish. A well-controlled spray pattern ensures that paint is applied evenly and specifically where intended, which is crucial for achieving high-quality results.

Although other methods mentioned in the options may have their benefits, they do not directly address the issue of overspray as effectively as proper masking and air pressure adjustments do.
