Default HVLP question spraying water-based poly

Ahhh my HF gun comes with a 1.4 tip... and as I am just now learning
that may make it come out to thin though I'm not sure I understand the
mechanics of it. So perhaps that is part of the problem...


Nope - the tip does not make it come out thinner - smaller tips require
thinner material. For a 1.4mm tip you would want quite a thin material, or
it will not spray it well. Start adding more reducer (water for water bases
materials) and test shoot until you get a good pattern. Increment the
amount of reducer by 10% or so until you get t good, shootable mixture.
Keep note of how much reducer you are adding so that when you get to the
point where it's spraying well, you can reproduce that ratio of reducer to
material later on.
