Measuring the viscosity:
Using the viscosity measuring cup
1. Thoroughly stir the coating material before starting measurement.
2. Immerse the viscosity measuring cup
(contents 100cm3) completely in the
coating material below rim level and
allow to fill.
3. Lift the viscosity measuring cup and
measure the time in seconds until the
flow of coating material stops.
4. This run-out time is called DIN
seconds (DIN-s).
Viscosity table:
Paint is “thinned” by adding the substance upon which the paint is based.
If it is water-based paint then water is added; if oil based then mineral spirit
or manufacturer’s recommended thinner is added. If the paint requires
thinning, start with a 10% dilution of the paint. To do this, partially fill a
container with one quart of paint. The viscosity cup supplied with the unit
holds 1/10 of a quart. Block the hole in the viscosity cup with your finger
and fill up with the required thinner. Add the thinner to the paint and stir,
and re-measure the viscosity. If the paint requires additional thinning, repeat
this step by adding 5% (5% will be equal to half a viscosity cup) with the
required thinner until desired viscosity is achieved.
