Primer: Everything You Need To Know
by Krista York
Primer is a key product in any paint project. Priming helps prep, seal, and protect the surface, which results in a better-looking interior and/or exterior project. Primers work well to seal in stains, create a smoother, more leveled finish, and will assure higher adhesion between the top coat and the surface.
If you’re like most homeowners you do not want to use your time priming, and I can’t blame you. From an outside perspective, primer may just seem like another layer of paint. However, priming and prep work is essential to creating a beautiful finish. Now, let’s look at when priming is necessary and when it is not.

Why You Might Need A Primer
Priming before painting is often necessary when dealing with problem surfaces that will not handle paint well. You should use a primer in the following scenarios:
- Raw unfinished wood
- Raw drywall
- Masonry
- All bare surfaces that are not porous
- Uncoated metal or plastic
- Water stains and other types of stains
You may also want to prime if you’re concerned about a darker color bleeding through, glossy areas, grease, or any areas that make paint difficult to adhere to the surface.
When Priming Isn’t Necessary
If the area being painted is a clean, dry, low porous surface that’s in good condition then priming isn’t necessary. Typical spaces that do not need priming would be a dining room or a bedroom. You can skip priming if:
- There are no stains or marks on the walls
- The current and new colors closely match
- Painting over previously painted surfaces
Don’t Trust Paint and Primer Combos

Paint manufacturers like to brand their products a “paint and primer in one” product, but don’t buy into the myth. Simply put, this is just a fancy marketing tool to make a product stand out. Sadly, the average consumer is led to believe that these two-in-one products are the same as priming PLUS painting. Most of the time, the only thing that has changed is the label. This is a clever move as most DIYers want to save steps and keep the project as simple as possible.
The best analogy is 2-in-1 shampoo and conditioner. Yes, a 2-in-1 will clean your hair, but shampoo and conditioner functionally do different things to your hair. While you might be satisfied with a 2-in-1 solution, you will have better results with a separate shampoo and conditioner. The same is true of paint and primer.
In reality, most of these products don’t even contain any primer. They usually just add a higher concentration of solids to make the paint thicker, so it’s more likely to hide the previous color of paint. Don’t fall prey to this myth. Call a professional painting company that uses high-quality products to help you complete your job so that it looks beautiful and is long-lasting.
