Spraying Technique
The spraying result depends considerably on now smooth and clean the surface is
before spraying is begun. For this reason the surface should be carefully prepared and
kept free of dust. Surfaces and parts not to be sprayed should be masked by covering
with sticky tape and newspaper. It is advisable to carry out a trial spraying onto
cardboard or a similar surface to find the most suitable spray gun adjustments.
Note:
Start spraying outside the surface to be sprayed and avoid stopping in the middle
of the surface being sprayed.
Always hold the spray gun at an even distance from the
object to be sprayed. The distance will very with the type
of paint being sprayed, 20cm is suggested to start with
and adjust if necessary. Move the spray gun evenly across
or up and down, depending on the adjusted spraying
effect (Fig. 9).
The movement of the spray gun should be by the arm rather
than the wrist to ensure that the space between the spray gun
and surface remains the same throughout the operation.
Uneven movement of the spray gun will give a uneven
surface quality (Fig.10). A even movement of the spray gun
will give a uniform surface quality.
