Lightly sand with 320 to 400-grit sandpaper to dull the finish. Application Techniques for Success How you apply the latex layer significantly impacts its durability on an oil base.
Durable Finish Techniques for Latex Over Oil Paint
Lightly sanding the oil surface with fine-grit sandpaper creates micro-abrasions, or "tooth," that the latex paint can mechanically lock into. This involves a thorough cleaning to remove any dust or grease, followed by abrasion.
Latex, or acrylic, paint, dries quickly through water evaporation, forming a flexible film that can bond well to many surfaces if the substrate is correctly prepared. Oil paint, with its slow drying time and complex polymerisation process, creates a surface that is both flexible and chemically robust.

Instead, use multiple thin coats, allowing sufficient drying time between applications. Surface Preparation is Non-Negotiable Skipping preparation is the most common reason for failure in this process.
