We recommend you spend some time practicing on cardboard, newspaper or scrap wood to familiarize yourself with how the spray gun
works and the flow rate (i.e. how fast the material will spray ) before starting any work regardless of experience level.
Start with the paint flow dial (4) at its minimum setting so the trigger can not be pulled. Do not forget that the paint flow adjuster controls the quantity
of paint sprayed. The spray gun will allow you to have great control for the spraying.
The gun has 3 spray patterns which can be changed by the external spray pattern adjuster from either a horizontal oval fan pattern, to a round
detailed pattern to a vertical fan pattern. When adjusting through patterns you will notice the oval fan pattern width reduce and increase as it moves
from horizontal to vertical positions. This is useful when you have particular size items you need to spray. The maximum width you can spray is 8”
down to 1” on the round pattern.
Horizontal oval fan pattern – is ideal for spraying up and down and for edges left to right (Fig.2).
Vertical oval fan pattern – is ideal for spraying left to right and for edges top to bottom (Fig.2).
Round Spray – is ideal for detailed areas or small objects (Fig.2).
Spraying with your Spray Station is very intuitive and through a little practice you will very quickly become a good sprayer.
When practicing – adjust the paint flow dial (Fig.4), and spray patterns to see the effect this has.
It is recommended you spend some time practicing on cardboard to familiarize yourself with how the spray gun works and the flow rate of the how
fast the material. When spraying always keep your arm at the same distance from the surface as possible and avoid moving your wrist as this will
help give you an even paint distribution. You should spray a maximum of 10”-12” from a surface, this will give you your maximum spray width.
The most commonly used technique for painting a large surface is the ‘crisscross’ technique, i.e. you spray the paint in a horizontal strip and then cross
over these strips by spraying the paint in vertical strips. When spraying always keep your arm at the same distance from the surface as possible and
avoid moving your wrist as this will help give you an even paint distribution.
BE CAREFUL NOT TO APPLY TOO MUCH PAINT IN THE SAME AREAAS THIS WILL LEAD TO SAGS AND DRIPS – APPLYING LIGHT COATS
IS ALWAYS BETTER UNTIL YOU GAIN CONFIDENCE AS YOU CAN ALWAYS GO BACK OVER WHAT YOU HAVE SPRAYED.
The most commonly used technique for painting a large surface is the ‘crisscross’ technique, i.e. you spray the paint in a horizontal strip and then cross
over these strips by spraying the paint in vertical strips.
1) To achieve a horizontal strip adjust to the horizontal position then pull the trigger and move your arm up and down (Fig.3).
2) When you get to the end of the line, release the trigger for a moment and then spray the product in the opposite direction slightly over lapping the
last strip you have sprayed (Fig.3).
3) Next, to achieve a vertical strip adjust the spray direction plate to the horizontal position then pull the trigger and move your arm up and down over
the horizontal strips you just have sprayed slightly overlapping the last strip you have sprayed (Fig.3).
HINT: HVLP technology produces warm air through the air cap allowing the paint to dry quicker which can enhance the final effect and allow you to
apply additional coats if necessary much sooner although you should follow the paint manufacturers recommended drying/curing times where
possible.
Always test spray onto cardboard to set up the gun as the flow rate will vary dependant on what you are spraying.
Evenly control the speed of movement of the spray gun. A fast speed will give a thin coat and a slow speed will give a heavy coat.
If spraying small areas or objects, keep the paint flow dial low as this will avoid excessive use of paints and will minimize overspray.
Avoid stopping and starting when spraying a surface as this can lead to too much or not enough material on a surface.
To ensure edges are covered, commence spraying just to the side or above/below the area being sprayed.
If using a latex paint regularly wipe the needle/tip to ensure the airflow and paint flow are not restricted.
Do not spray outside when humidity is above 60% or temperature is above 90˚F or below 45˚F.
