well i am painting my floor boards. i'm using a ppg epoxy primer with the correct 2:1 ratio with catalyst. no i just bought a gravity feed hvlp. harbor freight spray gun. i have been messing around with all of the controls and can't seem to get it to apply smooth without spattering. i'm running about 40psi. any tips?

 

well i upped the pressure to 50psi and made a few adjustments. seems to be doing a lot better now.

 

what gun do you have the 4340?

this should help with the set up

 

I also noticed the same thing on that same gun. I found out that the culprit was the end cap if not totally tight was allowing paint to seep around the needle and build up droplets eventually getting carried away by the spray and creating splatter.

 

thanks guys, got all the primer on. paint goes on tom. so i get to adjust it all over again

 

if its the 43430 gun start with the trigger pulled the adjustment on bottom of the gun where the air goes in pull the trigger with the psi at 50 and listen till the noise stays the same and dont touch it again then 3 turns out on the fluid and full out on the fan pressure arround 50psi with the trigger pulled thats where I start then its just maybe a 1/4 turn on the fluid in or out to get the nice cigar shape with nice droplets like the link i sent

 

set you pressure at 25 psi and turn the fluid control valve down. what you were trying to do was send to much paint of the gun wayyyyy to fast

 

do you have some kind of dryer or filter on the compresser you are using? pressure down,fluid needle in

 

all i know about the compressor is it's a new craftsman 17gal. i'm all done with the gun now. but i'm sure the tips will help me later. thanks!
