A WORD ABOUT LATEX
Although latex paint was never originally intended to be sprayed, a
professional finish 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
20-30% depending on the brand of
paint.
And to improve the finish 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 Com-
pany in Ohio. In the USA Call 1-800-321-3444 for your nearest
supplier. (In the U.K. 0845-0618899).
The ideal Aircap size setup is either the No. 4 or No. 5 for household
trim, louver doors etc. The Latex paint should be ‘finish-quality’ and
not a cheaper grade.
When spraying Latex, please adjust the Fluid Knob to limit the paint
to a finer spray. This will increase the ratio of air to paint and result
in better atomization and a beautiful finish. (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 improv-
ing the quality of atomization). Also, it is usually helpful to remove
the air control valve so that more air passes through the spraygun.
Finally, adjust the pattern to a maximum size of 8” - 9” (20cm) -
smaller is ok.
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 #6 Aircap 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.
LEAKAGE FROM THE NOZZLE
This occurs when the Needle Packing Nut is
too tight
compressing
the Needle Packing #12 tightly around the Needle.
Half fill the cup with water. Attach the Gun to the Hose and turn on the
Turbine blower. Pull the Trigger and release. Check the Nozzle for
water spurting out.
Using the supplied wrench,
GENTLY
loosen the Nut (1 or 2 degrees
only at a time).
This is a very sensitive adjustment.
Again pull the
Trigger and release. Wipe away the water in between adjustments.
Repeat until no water is seen at the Nozzle Hole.
LEAKAGE FROM THE NEEDLE PACKING NUT
This occurs when the Needle Packing Nut is
too loose
.
Half fill the cup with water. Attach the Gun to the Hose and turn on the
Turbine blower. Using the supplied wrench,
GENTLY
tighten the
Needle Packing Nut 1 or 2 degrees only.
This is a very sensitive
adjustment.
Wipe away the water in between adjustments. Repeat
until no water is seen where the Needle passes through the Needle
Packing Nut.
It is a good idea to apply Light Machine Oil or Vaseline to the Needle
Shaft where it passes through the Needle Packing Nut and work it in
and out by pulling the Trigger back and forth. This will lubricate the
Needle Packing #12.
