Why Oil Paint Takes Time to Dry?

The drying phenomenon of oil paints is an exciting aspect to understand. They have a minimal quantity of water due to which no evaporation occurs.

On the other hand, regular paints like acrylic, water and gouache paint dry up in no time. The Oil-mediums are quite different from other colors as they dry through a chemical reaction known as Oxidation. In this process, the oil paints gradually react with oxygen and polymerize.

The time required for the oil paints to get wholly cured and hard is called the drying time. The science behind the oil paints is that its drying time depends on several factors such as;

  • Environment
  • Brand of the paint you use
  • Quality of the pigment

Quick Tips to Make Oil Paints Dry Faster

Here are some easy to implement but effective tips by which you can make oil paints dry faster-

1. Choose the Environment Carefully

Painting in a ventilated area can help a lot. Ensure that you open the windows, fans or any source of air for speeding up the drying time. Exposure to natural light also helps to increase the evaporation process of volatile solvents.

Bonus tip: You can also use hair dryers but make sure to adjust it on cool setting as a lot of heat can damage the painting’s shine. Also, blow the hairdryers at the back of canvas to ensure a debris-free painting.

2. Fat Over Lean Concept

Don’t feel puzzled by the flashy phrase. It is a theory that explains the artists to combine the drying mediums or thinners with their oils. Here is a trick for you:

When applying the initial layers, use more drying medium and less oil paint. This will help the initial layers to dry faster. And then, you can apply the finishing layers that can have more oil paint and less drying medium. However, you must know which drying medium works best for you.

Bonus tip: You can use turpentine to thin your oil paint before applying the base layer

Bonus tip: Do not use acrylic paints on oil paints as this would cause the colors to mix up.

5. Apply Thin Layers when you Start
