To create a successful bond, the oil surface must be treated as a non-porous substrate. This approach is not inherently wrong, but it requires specific preparation and knowledge to ensure the integrity of the final artwork.

Instead, use multiple thin coats, allowing sufficient drying time between applications. A glossy, cured oil surface provides little opportunity for the latex paint to bond mechanically.
Consider using a bonding primer specifically designed for transitioning between different paint chemistries. If the oil layer does not provide a sufficient tooth for the latex to grip, the topcoat can develop cracks, peel, or simply fail to adhere properly, leading to an unstable finish.

Lightly sand with 320 to 400-grit sandpaper to dull the finish. Applying a rigid, water-based layer over a flexible, oil-based layer can create problems as the substrate moves or ages.
