The best practice is to allow the majority of the oil paint to cure before applying the varnish, according to Natural Pigments. The advice to wait 6 to 12 months for most paintings is based on a misconception of how oil paints work. Oil paints are made up of a mixture of pigments and a solvent. When the solvent evaporates, the pigment particles are left behind.
This is why the paint is called “wet” and not “dry.” The solvent is usually water, but it can also be other solvents such as ethyl alcohol, acetone, methanol, or isopropanol. In the case of water-based paints, it is common practice to add a small amount of glycerin to the water to make it more viscous, which makes it easier to work with.
However, this is not always necessary, and some paints can be worked with just as well without the addition of any additional ingredients. It is also important to note that some oils are more prone to drying out than others.
