A Guide to Spray Gun PSI When Painting Your Car
When painting your car, getting the right spray gun PSI (pounds per square inch) is crucial for achieving a smooth, professional-looking finish. The correct PSI setting depends on the type of paint, spray gun, and air compressor you’re using.
Understanding PSI for Different Paint Types
- Base Coat: Most HVLP (high-volume, low-pressure) spray guns require 25-30 PSI at the gun for an even base coat application.
- Clear Coat: For clear coats, a slightly higher PSI, around 30-40 PSI, helps achieve a glossy, flawless finish.
- Primer: Primers are thicker and may require 20-25 PSI for proper atomization and smooth application.
Adjusting for Best Results
It’s essential to adjust the air pressure at the regulator and test spray on a scrap surface before painting your car. Too low of a PSI can lead to orange peel texture, while too high of a PSI may cause excessive overspray and paint waste.
