I went out to the garage today to spray my Bachmann Spectrum Dash 8, I filled the compressor up with air and tested the spray on my new Badger Anthem and new bottle of Model Flex Yellow and noticed it splatters at various psi. I tried to figure out whars wrong bit nio luck. I do have a vapor trap thats located before the hose. So can someone maybe tell me how to fix this if they know? humidity was 68 and temp was 83. [:(]
If it is like a Paasche, back the needle off a bit. I just posted on another thread about how I use a white sheet of paper to test on before spraying the “patient”. I have sprayed in the same humidity, but not at those kind of temps. What psi are you painting at?
Also, did you thin the paint at all? If it is too thick, it tends to be messy. I have not worked with Model Flex, so I am not completely familiar with its tendancies.
I have used 25 yo 35 psi and csmith9474 model flex paint is by Badger made specifically for airbrushing.
I am speaking from using a Paasche H, but I spray between 15-25, but usually around 20. 35 lbs would definately cause a bit of splattering. Try around 15 lbs, work your way up from there, and see what happens.
Try thinning the paint more, and increasing the pressure. I’ve noticed that Acrylics tend to require more psi, and definitely should be thinned by at least 30% or even as high as 70%.
I take it the higher pressure makes for a better mist with acrylics? I am about to paint with Alclad, but it is recommended to use a lower psi for that. Of course Alclad is a metal paint that does not need thinning, so I guess there are some other things I need to look at here. 35 lbs still seems awful high to me.
I will truely try all the suggestions you people gave me cause I really need this locomotive done for the cal installation. I dont want to put all my finger prints on the primer.
