What Airless Spray Tip Is Right For You? What Do The Numbers Mean?
What happens here
Consider High-Efficiency Airless (HEA) tips, such as those from Titan, and Graco's Low-Pressure (LP) tips. These tips are designed to operate at lower pressures (typically 800-1100 PSI), which helps reduce overspray by producing a softer spray. However, the speaker's experience indicates that while they reduce overspray, the paint droplets they produce are larger. This can lead to issues like 'wet overspray fallout' on nearby surfaces and an 'eggshell-like' or less glassy finish, particularly on exterior surfaces where a fine, smooth result is desired. For these reasons, he generally avoids using HEA/LP tips for exterior work.
Goal: Understand the characteristics and limitations of HEA and LP airless spray tips for exterior applications.
