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.
