Because the oil layer remains chemically resistant and non-porous even when dry, the water-based latex struggles to form a mechanical grip. Consequences of Ignoring the Mismatch Ignoring the physical properties of these paints leads to immediate and visible problems.
Latex Paint Over Oil Drying: Understanding Adhesion Challenges
The Core Issue: Adhesion and the Nature of the Bond The primary reason this combination is generally inadvisable lies in the science of how these materials bond. You cannot simply cover the oil with a new material; you must create a compatible interface.
As mentioned in the previous section, the absolute requirement is a correctly prepared surface. Before attempting any layering, understanding the science behind adhesion and drying times is absolutely critical to prevent future failure.
Understanding Latex Paint Adhesion on Oil-Dried Surfaces
Applying a flexible, synthetic coating over a rigid, slow-drying film is a recipe for disaster in the visual arts. This results in a bond that is more like a layer of dust sitting on top rather than a fused union.
