Apply a high-quality bonding primer to achieve a solid bond between the old oil-based paint and the new water-based paint. Use two coats of durable water-based (latex, acrylic-latex, or 100% acrylic) paint for a smooth, long-lasting finish.
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.
Oil-based paints cure to a hard, slick finish. Latex (water-based) paints cannot properly adhere to this surface without deglossing and a bonding primer. As a result, the latex layer peels in sheets under stress from moisture, cleaning, or expansion/contraction.
Get a lint free rag and apply the oil bond to the trim. Once everything you plan to paint is wiped down let it sit for 60 minutes. After 60 minutes add 16oz to a gallon of whichever paint you're planning to use, mix it up and paint away. On the second coat do not add the oil bond just top coat with the paint as normal.
Black, blue, and green: Darker shades like navy blue and hunter green feature intense pigments that can resist coverage, particularly by lighter colors. (If you've ever tried adding white paint over dark paint, you know how many coats you need for a solid finish!)
Oil base. Kilz is a good option. Clean well, sand eith 220 and use a solvent wash like liquid sand paper to soften the oil base original finish. Oil base Kilz is a go to primer when using latex topcoats.!
Fortunately, this common misconception is just not the case. So yes! You can (and should) successfully paint latex over oil-based paint. Just know that proper preparation is essential to ensure strong adhesion and a lasting finish.
Don't try everything you see on Tic-Toc Baking soda will thicken acrylic paint— but it's not acrylic friendly and will crack and fall apart in a short time. Here's a more detailed explanation: Interference with Binding: Acrylic paint relies on binders to hold the pigment and create a cohesive film.
Latex paints will not stick to oil based paints. The exception is that an oil based primer may accept any kind of top coat paint. For that reason, an oil based primer is recommended to be applied over any oil based top coat, then a water based paint may be used as a top coat.

Oil-based paint produces a very hard, slick surface which isn't good for a latex top-coat to adhere to. So if it's oil, you'll need to go on to step #2. Second, you'll want to use a good primer before putting the latex paint over the oil.
You can put acrylic/acrylic-latex/latex over oil, but only with proper prep. You have to either de-gloss the oil (with, what else, a de-glosser, basically a chemical cocktail, or by sanding), or you have to use, as you did, a bonding primer such as BIN or Kilz, or one available at various paint stores.
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.
Yes, you can apply water-based paint over oil-based paint, but proper surface preparation is essential for good adhesion and a durable finish. This involves cleaning, sanding, and priming before applying the water-based paint. For interior projects, these steps are generally straightforward and effective.
❤️ NEVER paint latex paint over oil based paint without using a good 'BONDING' primer, then the letting primer cure according to directions. 5-7 days.
Paint blistering occurs when the paint film lifts from the surface below, forming visible blisters or bubbles in the paint. This is usually caused by heat, moisture, or both, and can eventually lead to peeling if left untreated.
Professional artists use both acrylic paint and oil paint depending on their style and the demands of their projects. Many artists who work in realism or portraiture prefer oil paints for their blending capabilities and depth of color.
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.
Can You Paint Over Oil-Based Paint Without Sanding? While sanding is generally recommended for strong adhesion, there are cases where you can skip it—particularly if the existing finish is smooth, intact, and not high-gloss.
It is fine to use latex paint over oil-based paint, but you must use an oil-based primer before you do. This is such an important DIY note that I am going to repeat it in bold and italicized text: Before you cover an oil-based paint with latex paint, you MUST use an oil-based primer.
