I wonder if anyone out there has tried using a high volume low pressure spray
unit (HVLP) for glazing. I just spent half a day spraying glazes watching
volumes of "collateral" spray billow around the spray booth and out the
exhaust system and thought maybe an HVLP unit would reduce waste and be more
environmentally acceptable.
If you've tried this out please share your thoughts. Thanks

In the Maritime provinces where it's wild and wet and the fall colours are
peaking. Open studio this weekend and hope the three day blow only lasts three
days.

Peter,
I used HVLP's in the auto body trade spraying cars. They were developed for
2 main reasons. 1. More paint solids ie. air polutants, go on the car.and 2.
The paint was getting so high tech, it costs about $100+ a gallon, ready to
spray. The transfer rate for HVLP's (with paint) is near 90-95 %. You want
ALL of that $100 finish going on the panel! They work well with glaze also.
Your BIG draw back will be cost. The last HVLP I shot with was $500 plus.
Since then, some lower priced hvlp guns may be available, but my solution
would be a simple gravity feed with a larger spray tip for thicker
material.That's what I use.You could aquire one at your local auto paint
suplier for around $100. They don't take to water very well unless you get
one for water base primers. Hope this helps, email me if you need more info.

Dear Jack,
I've been looking at some hvlp's and found a couple in the Whitney catalog.
If you have the catalog, 92JA, could you look at page 33 and tell me the
difference between the two, other than that one is gravity feed. One says
it has two tips 1.4mm and the other 1.8 for heavier materials. These guns
are $80 and $100. What would I need to look for to tell if a gun is worth
spending money on?I suppose these would have parts that would wear out
easier? Is a guage necessary on the gun. The gun with the optional larger
tip doesn't have one and the other does. Since you are familiar with
these, I would certainly appreciate any education you can impart. I
understand why hvlp's are superior to regular guns, however, deciding which
hvlp is the problem.
Thanks,
