Proper Spraying Technique
If spraying with an HVLP spray system is new or
unfamiliar to you, it is advisable to practice on a
piece of scrap wood or cardboard before beginning
on your intended workpiece.
Surface Preparation
All objects to be sprayed should be thoroughly
cleaned before spraying material on them. Areas
not to be sprayed may, in certain cases, need to be
masked or covered.

Spray Area Preparation -
The spray area must be clean and free of dust in
order to avoid blowing dust onto your freshly
sprayed surface.
How to Spray Properly
Partially pulling the trigger will start
the turbine, but no material will spray
STOP
until the trigger is pulled fully. It is
recommended that the trigger first be
pulled partially in order to start the
turbine before a spray pass is made.
• Position the spray gun perpendicular to and
one (1) or more inches from the spray surface,
depending upon the spray pattern size desired.
• Spray parallel to the surface with smooth passes
at a consistent speed as illustrated below.
Doing this will help avoid irregularities in the
finish (i. e. runs and sags).
• Always apply a thin coat of material on the first
pass and allow to dry before applying a second,
slightly heavier coat.
• The closer your sprayer is to the object being
sprayed the lower the overspray.
Even coat throughout
Keep stroke smooth and at an even speed
• When spraying, always trigger the spray gun
after spray pass has begun and release trigger
before stopping the pass. Always keep the
gun pointed squarely at the spray surface and
overlap passes slightly to obtain the most
consistent and professional finish possible.
