A WORD ABOUT LATEX
Although Latex Paint was never originally intended to be sprayed, a professional
nish can be achieved by following a few simple rules. (Please do not confuse latex
with the newer water-based coatings). For work such as cabinetry or trim, our
equipment can be used successfully with latex paint. The latex will have to be
thinned with WATER - approximately 10-30% depending on the brand of
paint. And to improve the nish even more, you can use an additive that will slow
down the drying process so that the paint levels out nicely. One product available
is Floetrol from the Flood Company in Ohio. Call 0845-0618899 for further
information.
The recommended air cap size setup is either the 1.5mm or 1.8mm for household
trim, louver doors etc. The latex paint should be ‘nish-quality’ and not a
cheaper grade.
When spraying latex, please adjust the Fluid Knob 10-2093 to limit the paint to a
ner spray. This will increase the ratio of air to paint and result in better
atomization and a beautiful nish. (Factually speaking, it doesn’t increase the ratio
of air to paint but does the opposite - it allows the air atomizing power to work on
less paint thereby improving the quality of atomization). Also, it is usually helpful
to remove the air control valve so that more air passes through the spray gun.
Finally, adjust the pattern to a maximum size of 8” - 9” (20cm) - smaller is ok.
Apply a wet coating (wet like a lake).
Although it is possible to use our equipment for house painting (walls), and many
end users do, we feel that an airless gun or power roller is better suited for that kind
of job. However, if you decide to do this kind of work, you will need the 2.0mm or
2.5mm air cap set.
Remember, when you buy a can of paint, lacquer, polyurethane, varnish etc. over
the counter, it will most likely be formulated for brushing. That means, it will be too
viscous (thick) and will require thinning to spray successfully. This is true even
when spraying is mentioned on the label of the can. Check with the manufacturer
of the coating to obtain advice on thinning their product. Unfortunately, sometimes
you may encounter Technical Sales Personnel that have very little experience or
knowledge about HVLP Turbine spraying.

GENERAL CLEANING
To clean the gun after each use, empty all paint from the cup. Use a solvent-soaked
rag to clean the residue in the cup. Then, spray some clean solvent through the gun
into a clean rag (to avoid lling the room with unnecessary spray) or a bucket.
Repeat until the inside of the uid passages in the gun, metal uid tube etc are
clean. Use the wet rag to wipe off the air cap and tip of the uid nozzle.
The air cap can be soaked in thinner.
If this type of cleaning is done while the paint is still wet in the gun, it should be
all that is necessary to keep the gun clean enough for next time. Do not leave
liquids in the cup overnight or for long periods.
Do not restrict the uid nozzle when cleaning (by putting your nger over the
nozzle orice) - this will drive thinned paint up the pressure tube and into the spray
gun which is undesirable.
PLEASE DO NOT USE A WIRE BRUSH OR ANYTHING METAL TO CLEAN THE
GUN OR CUP AS THIS WILL CAUSE DAMAGE.
DO NOT disassemble the cup assembly - threads in your cup have been sealed
at the factory to prevent leakage under pressure.
The standard 1 quart (1000cc) cup can be used with most coatings (including
water-based). Also available as an accessory is our Teon Coated Cup 10-2008.
CAUTION | Never soak the complete spray gun in solvent as this removes the
grease from the parts and distributes thinned paints throughout the air passages.
It could also damage internal parts such as the spindle valve or valve seals.
It may sometimes be necessary to soak the air cap, nozzle, needle, air diffuser and
air divider. You may soak only the metal parts in solvent and clean with a soft
bristle cleaning brush. To reassemble, first oil or grease all moving and threaded
parts.
CAUTION | Do not lay the gun down on its side with liquid material in it.
When not in use the cup lid should not be clamped down hard as this will
cause the gasket to atten out.
