Spray Techniques; Installing Nozzle Retaining Cap - Graco ToughTek F340e Operation, Repair, And Parts

Spray Techniques

1. Test the spray pattern on cardboard. Hold the
applicator 6 – 18 in. (150 – 450 cm) away from the
surface. Use this spraying distance for most
applications.
2. Adjust fluid flow until material flow is adequate.
3. Adjust the applicator air ball valve to achieve a
uniform round spray pattern.
4. Consider the size of aggregate in the material and
the coarseness of the spray pattern. Larger nozzles
allow heavier patterns.
5. Overlap each stroke 50%. A circular overlapping
pattern may give the best results.
When spraying small confined areas use the air ball
valve and air needle position to make fine adjustments
without adjusting the pump.
Higher pressures may cause excessive wear on the
fluid pump. Select a fluid tip large enough to spray at low
pressure. Some materials will pack-out at higher
pressures.
