Again...we delve into finishing. I hate to beat several dead horses about this...but the choices of finish and the application methods available, provide roughly 128,000 (through repeatable permutations) options for finishing...and I am very confused, especially when it comes to spraying.
I have never sprayed before, but as I have several large pieces nearing completion and ready for finishing, I am thinking of spraying for the first time. I am very confused about the differences between traditional gravity fed/siphon sprayers, and the HVLP systems that I have been seeing people talk so much about. I understand that the traditional systems generally allow for a greater amount of wasted material, due to a much greater amount of overspray. Whereas the HVLP's pressurize the storage container and send the material out at a much slower velocity, providing less overspray with the same amount of material delivery.
I have heard good and bad about both, and read about the same. So here are a couple of questions that I would like to present, and get forum feedback.
Do differences in materials determine when you would use a traditional sprayer vs. an HVLP system?
I have several large compressors with filters...can I use them to power an HVLP system via regulators, or do I have to buy one of the turbine systems?
When spraying material, are there guidelines for the viscosity of the material?
If there are guidelines, where are they and how do you measure materials against these guidelines (please tell me that I don't have to just "get a feel" for it...because that means a lot of messed up wood! :nah: but...practice makes perfect I guess )
I am sure that these questions are rudimentary and simple, but I would really like to hear what others here are doing, because my next questions are regarding hardware recommendations for each type of sprayer. :gar-Bi
