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.

those are the two tip size a 515 and a 310 is typically uh you know what I use I want to talk about haa tips so they're high efficiency airless tips uh by Titan they run at low pressures um 800 to 1100 PSI and from my um testing and experimenting you know on an exterior the droplets are a lot bigger with an ha tip so you you what um I found you know if you're over walkways driveways Etc or you're spraying like sofits overhead you're getting a lot more um wet overspray Fallout so you're going to be getting your know wet paint falling in your face if it's not flash drying before it hits the ground because the droplets are too um too big you're going to get wet overspray landing on um driveways sidewalks Etc stuff like that haa tips are great tips uh for interior painting where I I don't think where you don't have to worry about overspray they do give a really nice um good feathered fan on it uh versus production tips that give kind of more of a sharp edge I do like them for um interior painting especially for uh ceilings I'll talk about Graco rack X LP tips they're low press tips kind of like a version of an haa tip a lot of these manufacturers of heirless tips are going to low pressure because of people's fear for overspray I don't think they really like resolve the problem by going to low pressure reducing overspray because once again LP tips same thing they have um a bigger droplet the bigger droplet is more likely going to fall onto you know what you don't want to get wet paint on and cause you know issues cleanup issues liability issues The Rock X the lp tips that are fine finish tips so like if you're using a 310 from my experimenting they come come out uh to egg Shelly of a finish and so they don't come out like really glassy the atomization is not breaking up the the the paints the the droplets of paint fine enough to give you a really fine finish I just thought it just looked too egg Shelly I steer away from ha tips rack X LP tips or rack tips Graco tips on the exterior of a house I do um have a recommendation when
