When priming kitchen cabinets, it is important to use a primer that will adhere well to the surface and provide a good base for the paint to adhere to. Some popular options for priming kitchen cabinets include:
1. Oil-based primer
Oil-based primer is a good choice for kitchen cabinets because it adheres well to wood and provides a smooth surface for paint to adhere to. It also helps to seal the wood and prevent any stains or tannins from bleeding through the paint.

2. Latex primer:
Latex primer is also a good option for kitchen cabinets because it dries quickly and is easy to clean up with water. It is also a good choice for kitchen cabinets that have been previously painted with oil-based paint.
3. Shellac-based primer:

Shellac-based primer: Shellac-based primer is a good choice for kitchen cabinets that have a lot of stain or tannin bleed-through, as it creates a tight seal that prevents it from bleeding through the paint.

It's also important to note that if you're going to paint over an old finish, you need to do a good job of cleaning and deglossing the surface before applying primer.
What to Consider When Choosing the Best Primer for Kitchen Cabinets?
1. Surface type: Make sure the primer is compatible with the type of surface you will be painting (e.g. wood, laminate, metal).
2. Adhesion: Choose a primer that will adhere well to the surface of your cabinets. This will ensure that the paint will adhere well and last longer.
3. Oil-based vs. water-based: Oil-based primers tend to have better adhesion and are better for blocking stains, but they have stronger odor, longer drying time and more cleanup. Water-based primers have less odor, dry faster, are easier to clean up, and are better for the environment.
4. Compatibility with paint: Make sure that the primer is compatible with the type of paint you will be using.
5. Brand reputation and customer reviews: Consider the reputation of the brand and read customer reviews to get an idea of the effectiveness of the primer.
6. Budget: As always, consider the cost of the primer and whether it fits within your budget.
