HVLP Paint Sprayer OT

[55 Fargo]

Hi all, today my mother went out in the cold and bought me a Gravity Feed HVLP Spray Gun that was on sale for $33.00 from $99.00, great lady to do this for me as we live outside the city a bit and she lives in the city.

Any way I did a test with it tonight, I used some water based enamel and I thinned it down with water and shot about 4 ounces on to a piece of cardboard, I was using 25 lbs of pressure, man did this gun paint nice, and very little overspray, for a cheap gun I think it will do the trick for me. The cup is only 20 ounces, would use a larger cup if doing a bigger job. I hope this gun will be adequate to shoot primer onto my car. My compressor is a Craftsman 30 Gallon upright with a 2 hp motor8.5 cfm @ 40 and 6 cfm @ 90. The gun is to be operated at 15 to 50 psi with 7 to 9 cfm, so I should be in the tolerable range...................Fred

Have You Used Your Sprayer Any More? Hows It Working Out?

No I havent Bill, I might try it with enamel paint to paint the trumpet horns on my 48, I will thin the paint by 10 % or so as it is a thick enamel almost like POR 15, will post results after I try................Fred

hey Rocky ! In my opinion, not being a professional painter, especially if you are use to high pressure guns, you will have to thin the paint more than before, alittle more air than they recommend, and switch your air line connections from 1/4 to to 5/16, ( more volumn ). My favorite gun is also just a cheap one !................just my thoughts...........

to truly mix the paint properly you should have a viscosity cup..that said and following the quidelines of the manufacturer will get you there. HVLP guns are restricted by law for the end user (you) not to exceed 10PSI nozzle pressure..yes a larger hose will be needed for the volume..however the mini-regulator at the inlet to the gun is needed to ensure that the guns inlet pressure is maintained to keep the gun at 10 PSI nozzzle. I feed my gun through 3/8 line, my inlet pressure is 29 PSI for max 10 PSI and excellent atomization. (estabilished by the maker and etched onto the gun) You can go lower on the inlet pressure depending on the size item being painted and keep "bounce" to a minimum. Establishing good paint control and regulated inlets pressure will ensure after cleaning the gun you can go back to the same settings by counting the turns form seated to operational after assembly. Fine tune from there based on viscosity of media..DO install the regulator..keep dusting under control by not exceeeding the outlet PSI.

Hi guys, its only Tremclad paint (canadas rustoeum, it's fairly thick to begin with, manuacturers reccomended thinning is 10% with mineral spirits for spraying. As far as the HVLP laws and regulations, they haven't got to my area yet, you can buy and use any type paint guns here, my nearest neighbour is 1/4 mile away, so I doubt my painting will annoy them. I have only 1/4 inchh id air lines, my compressor puts out 8.5 cfm @ 40 psi, it has a 30 gallon tank, should be okay for small jobs, don't plan to paint the car with it, just the primering. I have only tried this gun once, with a small amount of paint, I will definately need to tweak the settings to get a decent spray and volume pattern. But with all of my tools once I get used to it I hope it will be fine, I have no spray paint experience with automotive paints, but I am aware of viscosity mixture requirements...........Thanx Fred
