What happens here

To achieve a proper spray with a classic blue Graco nozzle, you typically need to increase the pressure. The video demonstrates moving from an initial pressure of around 90 bar (which caused tailing) up to 190 bar. This significant increase in pressure helps to atomize the paint more effectively, resulting in a cleaner, more uniform spray pattern without the 'cordage' or 'tailing' that was previously observed. The improved spray shows no noticeable excess paint on the edges, indicating proper atomization.

Goal: Adjust the pressure settings on your paint sprayer to achieve a proper, even spray pattern with a classic nozzle, eliminating 'tailing' and improving finish quality.

on the sides. So here we're using a nozzle, a classic blue Graco nozzle, let's say. So, to get a proper spray, we'll have to increase the pressure. I think we're around 90 bar here, and we'll go up to 190 bar to get something decent. Otherwise, to work with slightly lower pressures, I don't use these nozzles anymore. I switch to new low-pressure nozzles, and with these, you can work between 90 and 120 bar, so that reduces the... The overspray, so the ENF mist, there you go. So now we're going to increase the pressure to 180 bar.
