A standard drywall primer will likely fail on a glossy oil surface. Apply a high quality bonding primer specifically designed for slick surfaces to bridge the old and new paint.
How to Prepare Oil Surfaces for Latex Paint Application
High quality 100% acrylic latex paints offer superior adhesion, flexibility, and durability compared to vinyl acrylic blends. Oil based paints are typically cured by solvents that evaporate slowly, creating a dense network of polymers.
The goal is to either create a rough surface for the latex to grip onto or to completely remove the old oil finish. Applying latex over oil based paint is a common scenario in both residential and commercial projects, yet it presents specific challenges that require careful preparation.
How to Prepare Oil Surfaces for Latex Paint Bonding and Adhesion
These primers often contain specific resins that chemically grip the oil molecules while providing a porous surface for the latex topcoat to adhere to. Without the correct preparation, the new latex layer can crack, peel, or blister, leading to an uneven finish that fails prematurely.
