Preparation
Start
Before spraying, the material being used may
need to be thinned with the proper solvent
as specified by the material manufacturer.
never exceed the thinning advice given by the
coating manufacturer.
note: Make sure to consider which spray gun you
are using when determining whether or not to
thin the material. See “Notice”, previous page.
Do not thin with materials that have
a flashpoint below 70°F (21°C). The
material flashpoint should be shown
on the material container.
note: Material to be sprayed should always be
strained to remove any impurities in the paint
which may enter and clog the system. Impurities
in the paint will give poor performance and a
poor finish.
Thinning the material:
1. Stir the spraying material
thoroughly.
4. Unscrew the cup from the spray
gun.
5. After the material has been
properly thinned and strained,
fill the container to the top of the
neck.
6. Carefully screw the cup back
onto the spray gun.
2. Dip the viscosity test
cup completely into the
spraying material.
3. Hold the test cup up and measure the time in
seconds until the liquid empties out. This time is
referred to as Runout Time.
