Always remember to disconnect from the mains supply before filling the paint container
with spray able material.
Most paints are supplied ready for brush application and will need to be thinned before they
are suitable to be sprayed. Follow the manufacturer’s 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.
Plastic & latex paint 24 - 28 seconds
Water based paint 20 - 25 seconds
Primers 24 - 28 seconds
Varnishes 20 - 25 seconds
Oil based paints 18 - 22 seconds
Enamel paints 18 - 22 seconds
Aluminum paints 22 - 25 seconds
Car undersealing 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 spray able 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 to reduce
the flow and anti-clockwise 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, using a criss-cross pattern as shown.
