How much should I thin paint for pneumatc sprayer?
you did not mention what paint, you did not mention what sprayer.
remember, if you use solvent - opacity of the paint is sacrified, tints are less visible, metallic require more clear coverage.
for water based paints - except airbrush, usually no thinning is required, but you need to first stir it well (at least 3min on manual or 1min 30sec if mechanical stirer is used) strain it, i am using old stockings for that purpose in single layer, works very well for me and if nozzle is above 1.4mm up to 2.8mm there is no problem whatsoever. if this is splatter paint (nozzle 4.5mm or greater) do not even think about thinning it...
for acrylic - if nozzle is between 0.8mm and 2.8mm, procedure as above and you need to add specific thinner, usually up to 20% albeit in some cases up to 40% per volume) so paint will be about like ight cooking oil - water.
for oil paints and enamels - solvent should be not more than 20%, albeit you can increase it up to 40% in rare circumstances, if you are using hvlp gun, you can, if you yousing hp gun - no! it will disperse too much.
for two packs and urethanes - not more than 20% better keep between 5% and 10%
for latex - in rare circumstances you are allowed to use very, VERY specific solvent, and ususally not more than 10%, nozzle usually is 8mm or greater in these paints.
