Spray Techniques

Use a piece of scrap cardboard to practice
spraying techniques before spraying the
work piece.
•
Always spray with the least amount of
pressure required to provide the desired
spray pattern and rate of application.
Spraying at pressures higher than
necessary wastes material and can
result in an orange peel finish.
•
Aim gun straight at surface. Tilting gun to
direct spray angle causes an uneven
finish.
