I’ve been painting at this shop for almost a year now and I’ve been taking the advice of the painter who has been working and painting with Diamont longer but I just want to see what you guys think.
His Theory:
Shoot the base at 24.5 pressure before the trigger is fully pressed (so no base just air coming out of the gun)
and 3 wet coats to make metallics lay down flat.Sata:
29 fully pressedMy theory:
25 Fully pressedSo I just want to know what you guys find works best with diamont base .
By the way Im using a Sata nr 3000 1.3
Thanks Guys
It might be my gun because when i started there I painted at 25 full pressed and I thought it was too easy to shoot.
Everyone paints a little different so if what u spray at works keep using that. and if he gets the acceptable results at what he sprays at that is fine to.. it also depends on the gun u are using.. i don’t spray every color at the exact psi.. as some metalics need a little more or less psi to get them to match a little better.(give or take a few psi..) I don’t use diamont.and don’t spray with a sata..i use the devilbiss tekna and somewhere between 20-23 is what i use for base..
well it turns out its my gun.
I was spraying a lexus 8u9 and the hood was looking nasty.So I switch guns with my buddy(same 1.3 sata nr3000)and the metallics laid down flat
So I took my gun apart and found out that I installed my air ring incorrectly. The marker was at 10 oclock and it needed to be 12 oclock.
Rookie mistake but I’ll see if its back to normal the next metallic hood.

which air cap are you using on your tekna? im using the 7E7 aircap with a 1.4, have been trying to find the sweet
spot for spraying clear. I usually spray the clear (either energy pro or superior) at anywhere between 19 and 22 pounds wide open, with around 45 pounds at the gun. Just wondering if you found a specific Psi that works well for you, usually if I use the gun for base i will spray between 16 and 20 pounds.
:hij:Painter is spraying all ppg products and solvent basecoat,his settings will be different than yours.There are a couple of sikkens guys on here that use a tekna,so maybe they can chime in.I would think for clear it would be at least 25-28psi? Also are you spraying at 22 psi at the gun or 45psi,your post is a little confusing 😛
I use a Tekna with a 7E7 for Autowave right now. I am around 16-22 psi, rarely 16 though. Works great. I have used it for clear but find it works better with a 1.3 at around 27-30 psi for Superior. It is slower for clear than a RP.
I’m with Jayson, I’m not sure what you mean by 45 psi at the gun and 19 to 22? One sound low and the other sounds really high.

:hij:[/quote]Yeah i use the 7e7 aircap and like jayson said i spray ppg products so the ppg clears 3000 and 4000 i am shooting them at 23.5 psi.. i am guessing u have your regulator set at 45 psi. on the wall b/4 the hose for your gun??

I’m using the same for autowave…7E7, 1.4. Spraying at 24 PSI and 19 PSI for drop coat. I’ve used the 1.3 for clear on a couple jobs just fine…not enough to give a real opinion, though.

sorry for that confusing post boys, to clarify I set the air in the booth so that theres 45 pounds to the regulator of my gun, and then dial in gun pressure after that to 19-22 psi. I havent tried spraying clear with a higher pressure since I first tried the gun, but i recall that when I did it seemed to me as If the clear likes to flow out a little better at a lower pressure. Felt almost like the clear was over atomizing, or there was just too much air and not enough material.
I think you might be better off adjusting your wall regulator to 80psi and then dial in your gauge to desired psi,or if you have the digital gauge leave it wide open and adjust your pressure at the wall until your gun gauge reads what you want.40 psi at the wall will not give you enough volume of air IMO ;)You want to control the paint,not have it control you.If you get in the habit of relying on “flowout” for a nice job it can kick you in the balls,atomization is where it is at;)

Yes I do have the digital gauge. I used to have my psi much higher on the wall, but another painter explained something to the effect of why you dont need that much air pressure going to your regulator (wall). It made sense to me because why have more pressure going over 45-55 psi, when I would never really spray anything over 29 pounds?
“If you get in the habit of relying on “flowout” for a nice job it can kick you in the balls”
How so?
That is partly true,but depending on how long your hose is in the booth you can have a pressure drop of 20psi or more from the wall reg to the end of the airline,also you will not have the volume of air at that low of a pressure.
If your gun is atomizing properly and you have good spraying technique you will have very little flow out,Why?Your paint will be put on smooth.On the flip side if you put on thick wet coats at a lower pressure depending on flow out you can have runs,solvent pop,dieback,etc.That is why you want to control the paint,you don’t want the paint to control you(runs etc) make sense??how does the tekna compare to the sata
[quote=”Papipab” post=20117]how does the tekna compare to the sata[/quote]
Depends on the material being sprayed. For waterborne basecoat I think the Tekna works better than a Sata. For clear the Sata would be the winner every day. Not saying the Tekna cant do a good job with clear, the Sata just does a better job.
Been painting diamont for a few years and I use a iwata lph400 1.4 @ around 22psi 2-3 med wet coats and lays down perfect for me, but that’s me. I think whats comfortable for you and your technique is what you should spray with. I did use the tekna for awhile but now use it for clear as it does really put the material on.
