The two types of paint are not compatible, and if you try to apply oil paint over a latex base, you can expect issues like cracking and peeling. So, it's best to avoid using oil-based paint over latex. On the other hand, you can use latex paint over oil-based primer, but proper preparation is essential.
Yes, you can use oil based paint over a water based primer. The main worries with mixing solvents are using a water based topcoat over an oil topcoat as it won't adhere (or it will and then will crack and craze over time). Primers are designed such that the finish coat will adhere to to primer.
It's not recommended to use oil paint on unprimed wood as it can cause issues with absorption and durability. Priming the wood ensures better adhesion and longevity. For more painting techniques, visit my Quora Profile.
Not all primers are created equal. To solve common painting problems, choose the best paint primer for the job. If your paint job entails indoors and outdoors, an interior/exterior primer is good to use. Otherwise, use separate primers formulated for indoors or outdoors.
Latex primers are water-based and ideal for prepping unfinished drywall for painting. They are more flexible and fast drying, and are less brittle than oil-based primers, making them less susceptible to peeling and cracking.

You can't just paint directly over oil-based paint. Glossy surfaces will not take a second layer of paint well on their own. They need proper cleaning and priming. You can achieve that with the following steps.
If you put latex paint over oil, you'll end up with that fruit roll-up look all over your house because they just can't adhere. Since they're not compatible, they won't form a good bond.
Yes! But you must follow ONE simple rule to ensure the best possible finish: the underlying finish must be absolutely dry.
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.
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.
Use on interior and exterior surfaces including woodwork, drywall, plaster, paneling, masonry, brick, painted metal and properly prepared glossy surfaces†. Use under or over water-based or oil-based paints. Not recommended on flooring.
Zinsser Cover Stain 1 Gal. Oil Based White Interior/Exterior Primer and Sealer sticks to any surface without sanding and can be used under and over oil and latex topcoats.
Firstly, when painting with oils, it is important to adhere to the three rules of oil painting. These are 'fat over lean', 'thick over thin' and 'slow-drying over fast-drying'. This means that each layer of paint should be progressively more flexible, thicker and slow drying than the one below it.
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.
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.
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.
The general recommendation is to wait 1 to 4 hours before applying a topcoat after primer. However, this can depend on the type of primer used.
Alkyd-based primers are a good choice for both interior and exterior bare wood substrates. They are efficient in penetrating the wood's porous surface, and provide long lasting adhesion. You may also want to go with alkyd products if you have removed wallpaper because it seals the residual adhesive.
KILZ Concrete & Masonry Bonding Primer is specially formulated to optimize the adhesion of masonry coatings. With proper application, this product provides a sound foundation for coatings with excellent resistance to water, alkali and efflorescence.
Original Kilz Primer allowed more seep through when put in two coats to two different walls in the same area, whereas Zinsser provided superior coverage.
The end-goal for painting projects is to produce a very smooth finish: One way to achieve this is to lightly sand between each coat of primer and paint you apply using fine-grit sandpaper. Sanding between each coat of primer and paint is one way to achieve the best finish for any painting project.
Do I have water-based or oil-based paint in my house? The test to determine whether your paint is oil-based or water-based is pretty easy. Simply put some methylated spirits on a rag and wipe at a small section of your wall. If the cloth is stained with the wall colour, it is water-based.
