Viscosity is the thickness of any fluid and in paint, high
viscosity or viscos paint, comes straight out of the tube. In fact, it has the consistency
of toothpaste as you can see. One way to decrease the viscosity of paint is to add linseed oil to it. Another way to decrease the
viscosity of oil paint is to add solvent and in
this case, turpentine. And another way to use
low viscosity paint, is to simply paint with an enamel paint, which in the can is already prepared with a very low viscosity.
