Stain & finish mixes for HVLP sprayers

You'd be much better served by testing and adjusting viscosity and air/needle/nozzle settings for whatever it is you are about to spray.

What with viscosity difference in materials from maker to maker and all the various guns out there you have a lot smaller then a 50/50 chance that what someone else may use is actually applicable to your particular requirements will be from job to job.

I'm not sure I follow your question. I spray straight Enduro water borne polys, or I add a bit of flow enhancer. Certainly nothing to write down or keep track of... I also spray shellac and latex once in a blue moon. I thin the latex with water and add Floetrol. No secret recipe; just mfgr's guidelines.

Also keep in mind that viscosisty changes with changes in temperature. Finish material temperatures below 55-60 F will spray very differently than finish temperatures in the 75-80 F degree range. A little testing and a viscosisty flow cup, and some addatives will go a long way toware solving your spraying problems. Test can easily be done on scrap pieces of cardboard sheets salvaged from shipping boxes.
