For those of you interested in helping (and learning from my mistakes). Thought I’d post a video and some pics of my setup. I have no one here to tell me if I’m doing it right or wrong, so figured I’d ask my woodworking friends online. The two pics below are my spray gun and my compressor. Its probably on the small end, as far as compressors are concerned – but when I bought it, it said it works great with HVLP.

I am using a 2.0 needle (for paint). I’ve thinned the paint down with water (stirred until mixed completely). I’m spraying at 35 psi. To set the psi, I have the trigger pulled on the gun.

And here is the video of me trying to get the right fan/flow. Sorry the video is a little shaky – I’m recording with one hand and spraying with the other. Also, the video gets loud about half way through it (when the compressor turns on), so don’t have your volume all the way up.

I’m just curious if this is looking right, or if something needs to be fixed, tweaked, etc?

It doesn’t look like you are getting much fluid to come out. What is coming out looks well-atomized, but just not enough fluid. I have two guns like that – one with a pressure regulator, and one without. Depending on the length of your hose and size of compressor, there is a significant drop in psi from the compressor to the gun. I set mine to 35 psi at the gun. Then I set my compressor to 100 or so. If you add a small regulator to your gun, you will be able to dial in the pressure better.

Make sure the air vent in the top of the fluid cap stays clear. Also clean the filter below the fluid reservoir after each use. If either of these areas clog, it will greatly decrease the fluid output.

Let us know how it goes.

Thanks for the post, many of us need to decipher the HVLP code.

I also bought an hvlp spray unit (Earlex). I haven’t had the opportunity to use it yet as I first need to set up a spray booth and get an extraction fan. Your gun looks very good and seems to spray well, but I don’t know enough about spray painting yet to give any advice. I am looking forward to giving it a go. I hope you will get a lot of good use out of your new gun.

your paint is too thick, and you just dont have enough compressor, these small compressors just cannot maintain a consistent pressure, You have my email, we can have a chat about how to handle and get it on the right track

I agree that the paint needs thinning but your technique is wrong. You’re going back and forth without releasing the trigger. This gives you more build at the stroke ends and less in the middle. Your gun should be moving before you pull the trigger and release the trigger before you stop and return.

It looks like you’re using latex which can be difficult to spray with a small rig but usually can be done if it is thinned enough. Watch out for runs and don’t try to cover in one or two coats. When I spray latex I usually do so with a pressure pot which provides a steady flow to the gun.

Charles, I shoot you an email before the weeks is up – I’ve been super busy the last few days and havent had a chance to respond to you.

Greatview – this is just painting on some paper to test the spray. This is not my technique while painting the doors
