Flattening agent, need help

D

dbohemian

Just wanting to get some help. I have mixed the flattening agent in Universal as per instructions (actually 3 different ratios) and when spraying out a test panel I keep getting very small white dots (size of a pin-head).

I thought it was because maybe I had the ratio too strong or I had not mixed thoroughly enough. I made a weaker small batch and mixed till I could mix no more. I even tried one with the flattener disolved in the reducer first then mixed but I am still getting this precipitation of white dots.

Any ideas as to what is going wrong. Certainly human error.

Hopefully that helps. I should call it the stardust effect and charge lots of money for it.
 
order some 125 micron strainers for waterborne.. triple or quadruple strain it.. but before that that... put the flattner on a mechanical aggitator and shake the shit out of it.. helps a TON... also get a liquid flatnner.. some are more liquid then paste.
 
Two ply Bounty paper towels if you cant get finer strainers. Pull plys apart and use one layer in your strainer. If anything gets through its time for a new batch. Works great in old basecoat too.
 
Only two things can cause this.
Too much flattener usually over 50%.
Or to high air pressure.

This looks like air pressure, drop it 5 bs.

Barry, your right. I dropped the pressure and it worked really well, no more speckles. But....The magic is in the person spraying and I screwed the pooch. It is uneven where i sprayed a different thickness (different gloss levels) and I got a zit on it and can't buff it out. Uggh...This has a learning curve like everything else and sometimes I just want to do what i know. This particular job has just gone into the negative.

Am I the only one who is currently hating flat paint...:mad:
 
The slower it dries the glossier it will be-those thicker areas dried slower. The trash in these flattened clear jobs are always a nightmare because there's no buffing options. Are you using any reducer in the clear? What activator-fast/normal/slow? You'll have to sand the trash out and put on one perfect coat-sounds easy....
