OPERATION INSTRUCTIONS

PREPARATION   

 B 

Do not use textured wall paints or coatings as 
this wHIblock the nozzle.

To obtain the best results, it is important that you pre-
pare the surface to be sprayed and thin the paint to 
the correct viscosity, before you operate your spray 
gun. Always ensure that the surfaces to be sprayed 
are free from dust, dirt and grease. Make sure that you 
have masked the areas that should not be sprayed, 
using a good quality masking tape. The paint or 

fl

 uid 

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 purchasingy-
our paint.

THINNING

Always rememberto disconnect from the 

mains sup-ply before 

fi

 lling the paint contain-

er 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 thin-
ning the paint when used with a spray gun. The viscos-
ity cup will help you to determine the correct viscosity of 
paint to be used. To determine the correct viscosity, 

fi

 ll 

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 differ-
ent 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

18-22seconds

Enamel paints

18-22seconds

Aluminium paints

22-25 seconds

Carundersealing

25-35 seconds

Wood sealers

28-35 seconds

Wood preservatives

Wood stains

Nothinningrequired

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 viscos-
ity test until the correct thickness is achieved. Some 
sprayable materials contain particles and lumps. These 
materials should be strained before 

fi

 lling the paint con-

tainer.

SPRAYING    

 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 

 until the required volume 

of paint is spraying.

SPRAYING TECHNIQUES    

 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.
