What happens here

Prepare a test surface (cardboard or paper) and set the airless sprayer's pressure. Start with a High Production 515 tip and low pressure (~700 PSI at the pump). Spray vertical lines, observing the fan pattern. A low-pressure setting with this tip will likely result in a sharp, 'fingered' edge with visible lines and excessive overspray. Next, switch to an HEA 619 tip. Gradually increase the pressure to approximately 1100 PSI (at the pump, resulting in ~900 PSI at the gun). Spray vertical lines again, noting the significantly improved feathered edge, less overspray, and reduced kickback. This feathered pattern is ideal for smooth surfaces like ceilings, ensuring no hard lines or 'fingering' in the finish.

Goal: Achieve a feathered spray pattern with minimal overspray.

whole long so now I'm gonna set this thing up I got it set up and we're gonna show you I'm gonna start spraying right here with the pressure to low and then we're gonna show you as I adjust the pressure what happens to the spray pattern all right so I've done some testing right now I'm just gonna roll my paper now get a fresh sheet paper right here and this tip is typically wants to run in higher pressures it's a high production tip I have the pressure set at it's all the way down on below the HEA marks so it's really extremely low it's it around it looks like about 700 psi and I know somebody's gonna be curious about the lime green gun whip it makes this section of the hose a lot more flexible if you just hook the regular hose to the gun this banding which is typically on all regular hoses makes it less flexible makes it harder to move get in and out of tight spaces causes a lot more gun fatigue and the lime green hose whips are my own custom specked out hose whips that's got a lay light on it and says the idaho painter right on it a paint life product so if you want one of our custom hose whips go check out our store at my website the idaho painter calm or store dot the idaho painter calm where you can get our really cool shirts hats and a lot of the tools and accessories that I keep in my vehicles I'm gonna switch this thing over to a tighten HEA tip I got my bucket of tips right here if you've never seen one of these things this is a tip saver right here this bucket and these things are pretty amazing it organizes your tips keeps them down I got just about that much paint there that might tips sit in so they don't dry out that's now at about 1500 psi and I've got your think I've got a hundred feet of hose right here so it's probably dropping down to about a thousand psi at the gun which is typically what an 88 tip should be run out and so the benefits of that is less overspray let's kick back and let's fall out so here we go so I'm getting a fairly good feathered edge right here it's filling in pretty nicely but I still think that I want my edge to be a little bit more feathered and this is once again this is a 311 tip and so these tips are just a little bit harder to dial in you would typically use something like this - maybe sprays you know some trim or something if you wanted to control overspray so we're looking we've got some fingering right there and we're running yo at about let me see if at all so it was dropping down to the top of the green…
