28. Disengage trigger lock and trigger gun into a
grounded metal pail. Use a metal pail lid with a hole
to dispense through to avoid splashing.

29. Adjust metering pump air regulator (CD) to 30 psi
(0.21 MPa, 2.1 bar).
30. Dispense until clean, well-mixed epoxy flows from
the gun.

32. Perform the Mix and Integration Tests on page 53.
When necessary, engage trigger lock (1) then install
the tip (2) on gun.

NOTE: While spraying, it is best to continuously hold the
trigger. Do not release the trigger unless necessary.
This maximizes the material temperature consistency
and minimizes fiber buildup.
33. Adjust metering pump air regulator (CD) to the
necessary spraying pressure and trigger gun to
spray material on a test panel. Look at ratio screen
to ensure it is reading the correct ratio. Continue
spraying on the test panel until the desired pattern
results then begin spraying the production surface.

34. Follow Flush Mixed Material on page 44 when you
are finished spraying if the potlife of the mixed
materials in the system could expire before you
spray again.
NOTE: Pot life of the mixed materials in the system is
much shorter than the dry time of dispensed epoxy
because mixed material potlife or working time
decreases with increased temperature.
