Understanding the Chemistry of Oil and Latex The fundamental difference between these two finishes boils down to their drying process and composition. After sanding, a thorough cleaning with a degreaser is necessary to remove sanding dust and residual oils that could block adhesion.
Essential Preparation for Latex Over Oil Paint Surfaces
Essential Preparation Steps To guarantee a durable bond, you must treat the existing oil surface rather than applying paint directly on top. The finish will typically resemble that of standard latex paint—a smooth, matte, eggshell, or satin finish depending on your choice.
