What are the ideal conditions temperature wise ect for airbrushing?
The other day was 35degrees celcius (hot) and i was getting a rough, gritty finish no matter how thin I made the paint. Im only new but will it be better if it was cooler? What about other weather factors?
Im on a mission to get the smoothest paint finish possible. Ive just found out to start and finish the brush away from the work. Any other tips like temp etc will be helpful.
Thanks…
Ideal conditions would be 20°C and 40 to 50 percent relative humidity.
You are spraying in an oven.
If you can’t reduce the temperature, try using a slower evaporating solvent.
The other factor to consider is with that high of a temperature is the humidity level. Do you use a moisture trap?

I had the opposite problem… AB at close to 40-50oF (low teens oC) and my thinned enamel paint had the “dotted/spider” pattern out of the AB. Air was just too cold ( I think)! Depressing to think I cant AB for a quarter of the year 
Rough, gritty finishes indicate that your paint is drying in the airstream before it hits the model’s surface. You probably don’t have a lot of control over the weather. When I have experienced that problem, it was due to me painting too far away from the model. Experiment with your air pressure and needle position. If you can adjust things such that you are able to paint effectively at a distance of two inches, give or take, from the model, the paint will probably stay liquid by the time it hits the surface, giving you a nice finish.
Abarne - thanks for the tip and info! Actually, I did end up AB very close to the model, but then had some “flooding” probs. For sure it was too cold to AB, will have to simple have some patience and wait for Spring
