I got Blue, not Green

[JCLP]

Hi Everyone. I trust everyone had a great Christmas and that you were spoiled by Santa.
I didn't get any Festool green for Christmas but got some Blue. Got myself a Fuji Q5 at a great price. Now I'll be able to spray BM Advance, I hope.
Cheers.

What made you decide to go with the Q5?  It sounded like you were seriously considering going the AAA route.

I purchased the Q5 because the deal was to good to pass up. I'm still looking at getting a AAA system though. I will eventually use my HVLP for small jobs like staining, applying poly on small items and small paint projects.
I still need to do a bit more research and make arrangements to go see a demo of CA Technologies H2O Waterbourne system.

I would probably do the same thing if I found the Q5 at a good price.  Let me know what you think of the setup when spraying BM Advance

Happy New Year!

Well I just tried BM Advance tinted grey, which makes it thicker then pure white out of the can, and the light at the end of the tunnel is getting brighter. Now, a lot of people will say forget Advance and spray Kem Aqua or the equivalent, but I am determine to figure out the proper combination to get a great finish. So the testing continues.

First I tried at 2mm needle, thin 20% with distilled water and my T70 siphon gun. Not a bad finish resulted from this but still not happy.
Second test, I tried a 2.5mm needle, thinned 10% with distilled water and used my Earlex Pro 8 gun and was able to lay a thin wet coat. Great atomization from a $160.00 gun. it looked great when wet. No roughness.

I have done other test with a 1.8 and 1.5 needle in my T70 and got crappy rough finish. Not enough pressure is generated in the cup, even with a 5 stage.

This paint does not like small orifices. If you have a compressor setup and can get lots of pressure, then you can force it through, but if you have an HVLP setup you will need a larger needle. DO NOT THIN THIS PAINT MORE THEN 10%. It does alter the chemistry of the paint.

Next test, no thinning, 2.5mil needle and my Earlex gun.

Cheers and Happy New Year to everyone.

If you think it's the need for more pressure on the cup or the product itself, why not try a pressure pot so you could put way over 10psi on the product?

I do have a quart size pressure pot from CA Technologies but the maximum allowed pressure in the pot is 10psi.Which is not enough for this Advance. I used a small compressor, Rolair JC10, to pressurize the pot to force the paint up the tube and to the gun tip and used all of the air from the Q5 to atomize the paint. I could go with a larger pressure pot but I didn't want to spend $1000 for a pot. Trying to  be economical. The photo is the pressure pot one I have.

I have a two quart Fuji branded PP but it looks just like the CA Tech and cast into it's top, "50psi MAX" but it has a threaded lid.  I just read an old review of BM Advance vs SW Pro Classic and it stated don't thin.

Have you had time to conduct any more testing with the Q5 and BM Advanced?

My Binks SG2 pot is rated to 50lb. You can find a decent one on ebay for a reasonable price.

This is very frustrating. I don't know why I can't get a smooth coat when sprying Advance. Maybe I'm not spraying it on thick enough. Need to find my wet gauge. It should not be this difficult.
Going to try 1.8mil, no thinning with the Q5. Let see what happens.

The SD sheet I have saved is for BM Advance Satin and reads 3.6 mils wet film.

Hi Bill,

I reviewed a video that Tom sent me spraying advance and he uses 1.5mil needle, a Q4 and the 3M PPS setup for his T70 Gravity gun. I have not tried the PPS setup as I have spent way to much money on trying to resolve the problems. No matter how misty the paint output is, it comes out lumpy. Tried every needle size, reduced fan and paint flow even a pressure pot setup and still not having any success.

Hey, hey! "Most Confused" is copyrighted.  [wink]

I just found that video but Tom doesn't mention or check the film thickness but 3.6 mils is what the sheet states.

Getting desperate and thinking outside the box.
As this paint needs to be applied thick, somewhere around 3.5 - 4.0 wet mils, and I need to get enough air to atomize the paint from my Q5, I decided to do something unconventional. I thinned the paint by 10% ( not unconventional ) with distilled water and used a 1mil needle with the 2mil air cap. Layed it on thick and now waiting for some levelling to happen. Should know sometime late tonight.
Fingers crossed.

That didn't work. Back to the drawing board.

Might have to wait for Tom to reply but just a thought.  Seems like the one difference is you have a Q5 and Tom has a Q4.  The Q5 is a bit higher pressure although it sounds like you might need a higher tip pressure to me but I'm no expert!  Since you have a Q5, doesn't it have the variable output or is that another model?  You could drop that a bit.

You have a pressure pot but its max is 10psi, correct?  If it were me(crazy, recently replaced brake lines on a car and tested every connection for leaks at 1,000psi with nitrogen), I'd take it outside run an air line to it at 25-30psi, cover it with a trash can and see if it goes boom.  If it holds try the PP if possible at over 10psi.

How did it look when it went on?

What is wrong that you say it did not work?

Wife and I are in Denver visiting the granddaughters. I'll respond as time allows.

I have a pps cup and attachment you can borrow.

How could that help?  The only thing possible with that is to pressurize the cup before it enters the gun but I'm unsure if does make any change which I do myself on my Gxpc.

It could be possible to pressurize a PPS cup or any cup as a matter of fact with an external source(compressor) with the proper fittings.  The people at 3M said that the check valve on a HO PPS cup opens at 15psi so in theory, one could go that high without becoming the color of the day! [eek]
