Understanding the chemical and physical properties of both paint types is the first step in ensuring a long lasting and professional result. You need a product engineered to bond to slick, non porous materials.
How to Choose the Right Latex Primer Over Oil-Based Paint
Furthermore, oil based paints are rigid and crack with temperature fluctuations, while latex is more flexible. This difference in flexibility means that stress from movement or temperature changes can cause the rigid oil layer to transfer stress to the latex topcoat, resulting in cracks.
Lightly sand the oil based surface with fine grit sandpaper to create a matte texture and key for the latex. A standard drywall primer will likely fail on a glossy oil surface.
Choosing the Right Latex Primer for Oil-Based Paint Surfaces
Apply a high quality bonding primer specifically designed for slick surfaces to bridge the old and new paint. High quality 100% acrylic latex paints offer superior adhesion, flexibility, and durability compared to vinyl acrylic blends.
