Latex paint, being water-based, requires a surface with a certain level of porosity or "tooth" to mechanically bond as it dries. Lightly sand the dried oil primer with fine-grit sandpaper to create a matte finish.
Maximizing Bond Strength: Using Water-Based Paint Over Oil Primer
Clean the surface thoroughly with a degreaser to remove any oils or residues. Wipe away all dust with a damp cloth and allow the surface to dry completely.
Applying a fresh coat of paint over a previously finished surface requires understanding the chemistry of the materials involved. Without the proper preparation, the slick nature of the oil primer can cause the latex topcoat to peel or chip away over time.

These products modify the surface tension of the oil primer, allowing the water in the latex mixture to evaporate while the resin component forms a strong mechanical bond with the underlying layer. When considering whether can you use latex paint over oil based primer , the short answer is yes, but success depends on proper preparation and the specific conditions of the project.
