Not all primers are equal, and a standard latex primer will likely slide off an oil surface. Oil-based paints cure through oxidation, forming a hard, impervious shell that repels water.
The Science of Latex and Oil Paint Adhesion: Why Preparation is Everything
The Strategic Use of Bonding Primers While preparation is vital, the true hero in this scenario is the bonding primer. Applying a heavy layer of latex over oil can trap solvents that cause the underlying layer to wrinkle or bubble.
By applying two or three thin layers, you allow each coat to cure properly, building up strength gradually without overwhelming the bond between the layers. Understanding the Chemistry Behind the Bond The primary reason this specific application fails is the absence of adhesion.

To combat this, you must physically roughen the surface using fine-grit sandpaper or a sanding block. Without proper preparation, the new layer will simply sit on top and detach from the old one.
