masking tape. The paint or fluid to be sprayed
should be thoroughly mixed and free from lumps
or other particles. Many substances can be
sprayed with your spray gun, but always check
the manufacturers recommendations before
purchasing your paint.
Thinning
Always remember to disconnect from the
mains supply before filling the paint
container with sprayable material.
Most paints are supplied ready for brush
application and will need to be thinned before
they are suitable to be sprayed. Follow the
manufacturers advice on thinning the paint when
used with a spray gun. The viscosity cup will help
you to determine the correct viscosity of paint to
be used. To determine the correct viscosity, fill
the cup to the brim with the paint. Measure the
amount of time it takes for the cup to empty back
into the can.
The table below shows recommended times for
different types of material.

This tool is not suitable for spraying dispersions
and latex paint, caustic solutions, acidic coating
materials, coating materials with granules
or solids as well as spray and drip-impeding
materials.

Adjusting the jet settings

A. Horizontal flat jet. This setting is used for
horizontal surfaces
B. Vertical flat jet. This setting is used for vertical
surfaces
C. Circular jet. This setting is used for corners,
edges and hard to reach surfaces.
If the paint takes longer than the recommended
time to empty, then further thinning is required.
Mix in a small quantity of the appropriate thinner
and use the viscosity test until the correct
thickness is achieved. Some sprayable materials
contain particles and lumps. These materials
should be strained before filling the paint
container.
Spraying
Fig. C
Fill the paint container with the correctly thinned
and strained paint. Connect the spray gun to
the mains supply. Aim the spray gun at a piece
of scrap material and operate the trigger switch
until paint is spraying. Adjust the output control
(2) until the required volume of paint is spraying.
Turn the output control in a clockwise direction
(B) to reduce the flow and anti­clockwise (A) to
increase the flow. Adjustment of the output control
will affect the spray pattern. A poor spray pattern
will concentrate the paint in the centre of the spray
and give a blotchy finish. A good spray pattern
will give even distribution of paint throughout the
pattern.

Spraying techniques

Fig. D
To obtain the best results, keep your spray gun level
and parallel to the surface at all times. Keep the
nozzle 25 ­ 30 cm from the surface and spray evenly
from side to side or up and down. Do not spray at an
angle as this will lead to paint runs on the surface.
Use smooth and even strokes. When spraying large
areas, use a criss­cross pattern as shown.
Fig. E
Never start or stop the spray gun while it is aimed
at the surface to be sprayed. Evenly control the
speed of movement of the spray gun. A fast speed
of movement over the surface will give a thin coat
