I have a Graco HVLP CX-9 Turbine and an .020 tip in the gun. I can't spray latex enamel successfully. All paints have gone to latex over linseed oil base where I could thin with product. Does anyone have any suggestions?
From contributor J:
Latex requires at least a .061-.072 tip and probably different air cap as well.
1. Bigger nozzle/needle.
2. Thin your latex with water until you get it to match the rated viscosity of your needle/nozzle.
3. Increase your fluid pressure if you are using a remote pot.
Adding water to water-base finishes is always iffy. But since it is latex paint that you are spraying, in all likelihood all you are doing by adding water is decreasing the paint's ability to cover/hide with color. Every few minutes you will need to clean off the paint from the tip of your nozzle. Use an acid brush and dip it in acetone to do this. Then, wipe with a rag and continue spraying.
