Topic tags/keywords: finish spray gun

I got a Binks 2001 and a Binks model #7 spray guns I was just wondering if anyone out there who sprays EM6000 with tha same guns on a compressor set up do u add a pressure regulator to your gun or just adjust the one that comes on the compressor? Also what is a good PSI to spray finishes at or about anyway? What works for u?

My regulator is always on the compressor. Too much extra crap on the end of the gun. I spray polys at about 35-40 lbs max. Lacquers a bit lower, maybe around 30 lbs.

I put a cheap Brass Inline Regulator on the end of each of my air guns. This allows me to make quick adjustments depending on each situation I encounter. There is still a main regulator and a dryer on the air compressor, but, with this little guy, I can make adjustments for each material and project I am working on without upsetting the entire system.

I use an inline garden hose valve in exactly the same manner as DS251, but on a turbine HVLP.

I usually spray lacquer at about 4 bar approx 60psi, I have a kremlin gun and thats what the rep told me to do, this gun is made especially for lacquer use. As for the regulator, most guns come with a small adjuster knob at the bottom of the grip for fine tuning, other than that just adjust it at the supply, like Paulsaid, you start to get too much on the end of your gun which adds weight as well as prevents you from getting into some smaller cabinets to spray them.

I have a C.A.T jr touchup gun with a 400cc gaivity cup. I have an air regulator/filter @ the gun plus one larger one on the compressor. The gun says 10 psi and that is what I set it to. I spray EM8000cv with a 1.2 mm setup and have had good results. I think the next time I shoot it I will thin it about 5% and see if I can get a finer spray.

I spray all types of lacquers; regular nitroceluous, pre-catalyzed, post catalyzed and conversion varnish. One thing I found to be very important if you are going to be spraying with a conventional gun and conventional compressor is to run your air line form your compressor to a seperate seperater/regulator, then a hose from there to your gun.
The seperater/regulator serves two purposes. 1; it will collect any water that’s in your air line ( that can screw up a solvent based lacquer finish as quick as anything and 2; It gives you a way to really fine tune your air pressure to your gun. You can leave the regulator on your compressor alone and run full pressure to the seperator/regulator and adjust from their.

I usually spray between 30 to 35lbs at the gun, but that really depends on your gun, how you have it set, what you may be spraying, and how you like to spray. Definitely the more presssure you’re spraying with the more overspray and blow back you will have.

My seperator/regulator is set up where I do my spraying and really don’t have to fool with it when it comes time to spray. I have a seperate hose I use for spraying and leave that attached to the seperator. All I do when ready to spray is bring my hose from my compressor over and quick connect to the seperator.

I drain my compressor often and I drain my seperator everytime I get ready to spray. In the summer, if I’m going to be spraying for any length of time, I make sure I drain every thing a couple times while working. You will be surprised how fast water can build in your compressor and lines if your compressor runs for any length of time.

You can buy those at HF, but they’re not that great, but I think your big box stores also carry them.

Just food for thought since I hadn’t heard anyone mention it before.
