The Role of a Bonding Primer Even with a deglossed surface, the risk of adhesion issues remains high without the right intermediary. Because the slick, glossy nature of oil paint does not provide enough grip, the water-based topcoat will not bond correctly and will simply sit on top, ready to chip away.
Deglossing Oil Surfaces For Better Latex Paint Adhesion
Drying times will vary based on humidity and temperature, but it is crucial to allow the first coat to cure fully before applying a second. Latex paint, on the other hand, is a water-based acrylic that forms a flexible, breathable film.
The short answer is yes, you can paint latex paint over oil based paint, but only with the correct preparation. Oil based paints cure through oxidation, creating a hard, non-porous surface that repels water.
Deglossing Oil Surfaces for Strong Latex Paint Adhesion
Understanding the Chemistry Behind the Layers The primary obstacle when covering oil based paint with latex paint is adhesion. A high-quality bonding primer is specifically engineered to stick to slick, non-porous surfaces and provide a key for the latex topcoat to adhere to securely.
