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 ow 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 ow and air power are

needed for spraying smaller surface areas, such as

corners, lattice, or spindles.

For this type of project, reduce power, material ow

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 ne

nishing. 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 ow.

• If you feel the material is going on too thick,

decrease the material ow 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.
