How Weather Conditions Affect Oil Paint Drying Time
This fundamental difference explains why patience is not just a virtue but a technical necessity in oil painting. The Science Behind the Wait At its core, oil paint dries through oxidation, a chemical process where the oil binder, typically linseed or walnut oil, reacts with oxygen in the air.

During this phase, the paint is still highly reactive, and pressing too hard with a brush or palette knife can disturb the surface, causing smudging or unintended texture.
