Proper Spraying Technique
Pattern Examples
Use the images and guidelines below in order to
assist you in achieving the desired spray pattern for
your project. These are meant to be general starting
points - you may have to slightly modify certain
controls on the system in order to get the exact
performance you need.
STOP
During a project, periodically wipe the
nozzle tip with a cloth to remove any
dried paint.
Large Surface Projects
Generally, high material flow and air power are
needed for spraying large surface areas, such as walls
and decks.
The iSpray nozzle is ideal for these applications and
is designed for broad coverage in either horizontal or
vertical spraying.
• The air cap position will determine the
movement direction of the spray gun.
Small Surface Projects
Generally, low material flow and air power are
needed for spraying smaller surface areas, such as
corners, lattice, or spindles.
For this type of project, reduce power, material flow
and switch to a narrow width when using the iSpray
nozzle.
The Detail Finish Nozzle provides an even narrower
pattern for smaller surface projects and fine
finishing. Moving closer to the spray surface
narrows the fan and moving farther away widens it.
• If you feel the material is going on too thin,
increase the material flow.
• If you feel the material is going on too thick,
decrease the material flow even further or move
the spray gun further away from the surface.
note: If after following the guidelines on
these two pages you are still not getting the
spray performance you need, refer to the
‘Troubleshooting’ section on page 16.
Besides adjusting the controls, other factors that
should be considered when spraying:
• Distance from the spray object - if you are too
far from the spraying surface, the material will
go on too thin, and vice versa.
• Material thickness - if the spray pattern runs
and/or is too splotchy, the material may need to
be thinned.
note: Only thin the material if absolutely
necessary to improve spray performance. Optimal
spray performance should be acheived simply by
adjusting the various controls on the unit.
If the material needs to be thinned, dilute the
material in steps of 5% - 10% until the desired
spray pattern is acheived.
• Spray gun movement - moving the gun too
quickly will cause the spray pattern to be too
thin and excess overspray. Moving the gun too
slowly will cause the spray pattern to be too
coarse or thick.
