Other folks have said they were going to use the low cost blower style
HVLP guns from Harbor Freight. Kurt Wild has my first one, and I think
its fair to say he liked it and has used it despite having a compressor. Please,
let's hear what the other users have to say good or bad....
We have used the Harbor Freight true HVLP/blower type units more than
a few times with good luck and no sign of problems. In fact, I like it better
than the compressor based unit because it delivers material faster and
allows me to build up a nice wet layer on our tiles. This thicker wet
layer seems to be better than multiple thin layers for our purposes. Note
that we spray tiles that are laid out flat.
This blower gun system varies in price from special to special from
about $69.99 to $89.99 and works rather like a gun hooked up to the
exhaust end of a vacuum cleaner. It works, and I think it has some inherent
advantages over compressed air based units which I rather went into
detail on in earlier postings (ie a larger nozzle that can be replaced
inexpensively).
Be aware, however, that there is some re-learning to do because it just
works differently than compressor models (that also like to call them
-selves H)igh V)olume L)ow P)ressure). I liked using ours from farther
away. It may well also require some adjustments to the viscosity of the
material you spray. Included with the kit is a plastic holding device with a
hole in it for indicating if your material needs to be thinned. In our case
I tried using the glaze thicker than the recommended but somewhat thinner
than we would normally use it and it worked just fine. It is entirely
possible some people may find it doesn't work as well even while others
will prefer it. Its largely an individual and subjective thing.
I can remember the days when HVLP first came out and they were very
expensive. Then, I remember, HVLPs being sold on the basis on less waste
and superior finish. I was sold on them as a superior mechanism. Then
came the amazing morph-guns for compressors with lower prices and the
whole quality/waste issue thing became blurred (for me any way).
Perhaps my best reason for thinking it is a potentially superior system to
compressor based guns for glazes is that the nozzle diameter is much
larger (for greater flow of air) thus allowing (also) a greater working
variety of particle sizes in the glaze. Also, anybody giving this a moment of
thought will realize that glazes are extremely abrasive. Having the liquid
go through the nozzle at lower velocity should increase the life of a nozzle.
By the way, the one thing that is Not needed for guns that you will use with
glazes are high prices for wear item replacement parts. I documented the
replacement part costs from Harbor Freight , and they seemed most reasonable
to me. This is not true for some guns....for example our first (US Made)
compressor gun was made by a company that wanted $50 for the replacement needle and
gasket kit. It went in the trash.
That's my 4c worth,

Connie,
for the first time someone asks for something Made in Argentina.This is
exactly like an insecticide sprayer but the nozzle is prepared for glazes.
The bottle works like a compressor because you push and it keeps pressure
inside, thus spraying smooth. When you stop pushing maybe it still has some
pressure inside, so it has a little device close to the nozzle that you can
twist and it liberates the pressure and stops spraying. I dont have one but
I was told that you
get tired if you need to spray a lot.
Its a good tool,nothing superb , and you dont get a cloud of glaze.Hope this
helps
""Axner has a glaze sprayer that doesn't use a compressor,
looks kind of like one of the sprayers you use to spray
insecticide... "Paintec Glaze Sprayer"
Has anyone ever tried it? does it work? I hate the noise
from the air compressor....
thanks,Connie""
