On the other hand, you can use latex paint over oil-based primer, but proper preparation is essential. Before applying latex paint over oil-based primer, make sure to sand and clean the surface thoroughly.
Yes, latex over oil base is fine as long as the oil base paint is 'dull' enough to allow good adhesion. Oil base over latex is not so good since latex paint is soft and will flex and oil base is hard and will crack.
Oil based primer is about as universal a product as exists. Latex, acrylic and alkyd regardless of sheen are all fine on top of it.

After priming, allow to dry 4 hours, test a small area for bleeding by applying the topcoat before painting the entire project. If the stain bleeds through, apply a second coat of primer and allow to dry overnight and retest before topcoating. Use Multi-Purpose Latex Primer over solvent sensitive stains.
On the other hand, you can use latex paint over oil-based primer, but proper preparation is essential. Before applying latex paint over oil-based primer, make sure to sand and clean the surface thoroughly. This will create a suitable surface for the latex paint to adhere to.
If the paint does NOT come off, it is oil-based paint and you will need to prime the surface with a bonding primer before applying latex paint. The primer can be latex, but it has to be a product that is made to prepare the surface and help with adhesion and that says “bonding” on the label.
May be used under and over any oil or latex architectural paint. The dried film is mold and mildew resistant.
They are Sherwin Williams Extreme Bond Primer, and Behr Bonding Primer. These top two primers were the very best at bonding in both the 24 hour test and the 38 day test.
When the oil-based primer is completely dry, the surface may still have a few small imperfections. This is typical even if you are a pro. The surface may feel chalky or even slightly rough. Using a Sanding Sponge, lightly sand the entire surface.
Both can work, but acrylic paint's elasticity and resistance to wear and tear make it better for high-touch areas and furniture. Latex paint works well for larger indoor projects where low toxicity and easy cleanup with a brush are priorities.
You can paint acrylic over oil paint pretty easily actually. All you have to do is follow the 7-step process in this blog post!
In addition, water-based paint is preferred when covering an oil-based product because it has a faster drying time and resists fading in the sunlight for exterior applications.
The glossy surface of oil-based paint makes it difficult for any other paint to bond. If you apply water-based paint directly over oil-based paint, it will flake and crack as the water-based paint pulls away.
Water based primer is usually used for walls and ceilings where there is new work and preparation is required, and oil based primer is primarily used for doors, windows, metal or woodwork. Enamel is hardier so surfaces that require heavy traffic or exposure to the elements are usually painted in enamel.
A premium-quality bonding primer can be top coated with almost any type of coating: alkyd, acrylic, latex, urethane, epoxy, lacquer and even hot solvent-based coatings.
Diving into a cabinet repainting project without priming often leads to frustrations down the road, such as peeling paint and visible stains that bleed through, diminishing the beauty of your hard work.
Extreme Bond® Primer is a high quality, waterborne, urethane modified acrylic primer. Designed for coating hard, slick, glossy surfaces with minimal surface preparation. Because of the exceptional adhesion of this product, sanding may not be necessary for most clean, paintable surfaces.
The glossy surface of oil-based paints makes it so difficult for any other paint to bond. That's why, if you apply water-based paint straight to oil-based, it will flake and crack as the water-based paint pulls away. So, to get oil-based ready to paint over, you need to take away a lot of that gloss.
It's ready to brush, roll or spray and can be topcoated after one hour with latex or oil-based paint. Use KILZ STANDARD Primer on almost all interior surfaces including wood, drywall, plaster, brick, masonry and more. Not recommended for flooring, glossy surfaces, mold and mildew prone surfaces or for stainblocking.
Placing Latex Over the Oil Primer
Oil-based primers take at least eight hours to dry. You may have to lightly sand the primer over smooth wood surfaces with 180-grit sandpaper to provide an easier bonding surface. Be sure to wash away any dust caused by the sanding and allow the area to dry before adding your paint.
If you must apply high-quality latex paint over oil paint, it's best to do so with a latex primer designed for use with both latex paint and oil paint. Using a paint primer can help ensure that latex and oil paint adhere to each other properly and create a lasting, durable finish.
If you have various stains, shellac Bonding primer is the ideal choice. It can be used to cover rough surfaces and old varnish as well as metal and ceramic.
High Exposure to Sunlight. Exposure to intense sunlight makes oil-based paints vulnerable to cracking. Elastic and latex paints tend to contract and expand when exposed to direct sunlight, which weakens their adhesive bonds.
