To combat this, you must physically roughen the surface using fine-grit sandpaper or a sanding block. Conversely, latex paint dries through water evaporation, creating a flexible film that requires a mechanical or chemical grip to adhere to that slick surface.
Oil Paint Surface Testing For Latex: Ensuring Adhesion and Compatibility
Wiping the surface with a tack cloth or a mixture of denatured alcohol ensures that the oily film does not interfere with the bonding agents. Applying a heavy layer of latex over oil can trap solvents that cause the underlying layer to wrinkle or bubble.
This process, known as de-glossing, creates microscopic scratches that provide the necessary grip for the latex to lock into. Applying a fresh coat of color over an existing surface is a common goal in both DIY projects and professional finishing, yet the interaction between different paint chemistries is often misunderstood.
