The table below shows recommended times for different types of material.
Plastic & latex paint 24 - 28 seconds
Water based paint 20 - 25 seconds
Primers 24- 29 seconds
Varnishes 25 - 35 seconds
Oil based paints 18 - 22 seconds
Enamel paints 18 - 22 seconds
Aluminum paints 22 - 25 Seconds
Car under sealing 25 - 35 seconds
Wood sealers 28 - 35 seconds
Wood preservatives No thinning required
Wood stains No thinning required
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.
6.3 Nozzle selection
1 mm: general purpose nozzle, suitable for high-viscosity materials such as emulsions, latex
and thicker type paints.
0.8 mm: suitable for oil-based materials, stains, sealers, lacquers, water-proofers and enamels
for small application areas.
0.6 mm: suitable for very low viscosity materials such as wood preservatives, pesticides,
oils,etc.
6.3.1 Adjusting the output amount
Please refill the container when it is almost empty.
If spray output before refilling is not a as you wis
h (spluttering / mist not good …) please re-
adjust by turning the output control knob to the appropriate position.
6.4 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 anti-
clockwise (A) to 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.
6.5 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 criss-cross 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 and a slow speed will give a heavy coat. Apply one coat at a time. If a further coat
is required, make sure you observe the manufacturers drying time recommendations before
applying a second coat. When spraying small areas, keep the output control on a low setting.
This will avoid using too much paint and prevent overspray. Where possible avoid stopping
and starting when spraying an object. This can lead to too much, or not enough paint being
applied. Do not tip the spray gun to more than 45 °C
