I use hundreds of gallons this product < ppg breakthrough .... it has 43% solids by weight, and about 32% by volume .. usually anything much over that is considered hi volume solids and are in epoxy or mastic finishes. you will need the higher 85 cfm and up air capacity turbine and use the correct tip and air cap to do this...there are many good [guns] out there. this is a complete setup that want let you down. one funny thing is , when they first came out with accuspray hvlp units, they claimed you could spray latex wall paints! that was bs. they do have them now that are pretty good with latex paints. this is a data sheet on it. it actually uses an automotive resin and is water borne. https://buyat.ppg.com/rep_pafpainttools_files/Pghpaints/TDB/V51-410.pdf
