HANDLING THE
SPRAY GUN
Hold the gun about 15 to 20cm from the
work (about the span of your hand)
If the gun is held to close excessive paint is deposited
and the gun must be moved faster to prevent sags and
runs. Holding the gun too far away causes a dry spray
giving a rough sandy effect.
Trigger the gun ON at the beginning of
each stroke and OFF at the end
Always use this method to avoid any build up of paint at
the end of the stroke due to the gun standing still. Begin
the stroke, then pull the trigger as soon as you pass the far
edge of the panel. The speed of the stroke should be
constant.
Move the gun parallel to the work
and at right angles to the surface
Tilting the gun up and down or moving in a curve results
in an uneven paint deposit.
Overlap each preceding pass by about one third
This ensures an even coating. The spray pattern is
specially designed with an oval shape so that when the
narrow ends of the pattern are overlapped, a uniform
coat results.
Spraying long work
You can spray a long panel or wall with either vertical or
horizontal strokes.
The horizontal stroke is usually easier as it is a more
natural action. Spray in sections up to one metre long,
triggering off at the end of each stroke to avoid build up
of paint. (see above).
Each new section should overlap the previous one
slightly to make an invisible join.
Spraying a horizontal surface
Make sure the paint tube is pointing towards the front of
the container when spraying from above (eg. table top)
and pointing towards the rear of the container when
spraying overhead (eg. ceilings).
Hold the gun nearly at right angles to the work*. Start
at the far edge and commence stroking from left to
right working towards you.
When finished, return the paint tube to the normal front
position.
* Note:
When spraying down on to a horizontal surface
hold the gun at less than right angles to the work to
avoid paint running up into the head of the gun from
the container.
