You should check if your material is of the correct viscosity (before pouring it into
the material container)
by performing the flow cup test.
To work out the DIN/s rating of your coating material:
HOW TO THIN COATING MATERIAL
If your chosen coating material took longer than 100 seconds to pass the flow cup
test, you will need to thin it using water or paint thinner.
To dilute your coating material:
v
Pour into a fresh container.
v
Add 1/2 a cup of water for every 3.8 litres of paint. (If using paint thinner,
add small amounts at a time, mix and check. A good ratio to use is 4:1
paint to thinner.)
v
Slowly mix using a wooden stick or spoon.
Place your finger over the hole of the
included flow cup and fill it to the brim
with your chosen material. At the same
time, release your finger from the hole,
and start the timer. Stop the clock when
the flow cup has completely drained of
paint.
If you find that your coating material has
a viscosity rate of, or above, 100 DIN/s
(meaning it takes longer than 100 sec-
onds for material to pass through the
flow cup), then it is too thick and will
need to be thinned.
