5. Price – bin primer vs kilz

At the same time, Zinsser’s prices can get as high as $10 per quart. In general, Zinsser is pricier, but it can also depend on the particular primer.
6. Rust-Inhibition – Zinsser 123 vs kilz
Zinsser is the right choice if you plan to apply primer on a metal surface before painting it. Zinsser Bulls Eye 1-2-3 contains a rust-inhibitor for metal surfaces, making it a great bonder for both clean and heavily rusted metal surfaces.
7. Variety – kilz vs zinsser
Both Zinsser and Kilz have a large variety of products, and they are pretty much at the same level in this regard. They will both bring generic primers to the table, and they also have bare wood primers, as well as indoor and outdoor primers.
Besides, what’s even better is that both brands come with different types of primers, such as water and oil-based ones.
8. Consistency – Zinsser vs kilz primer
Consistency is very important when choosing a primer. Depending on your project, sometimes you need thinner consistency, and other times, you need a thicker one.
So, if you want to choose between Kilz and Zinsser, here are some things to consider in terms of consistency.
Kilz is the better choice if you want something thinner and easier to stir. This is why the product is considered a good choice for beginners.
Besides being easy to stir, it is also easy to spread.
Moreover, Kilz comes with a better bleed through, which is something that can be bad or good, depending on what you want to achieve. And while thinner consistency is good for stirring and spreading, Kilz is said to not have the best coverage.
Proper coverage is important, and because of that, many DIY fans do not prefer Kilz because of its thin consistency.
Meanwhile, Zinsser is the one with a thicker consistency across the board, something that DIY fans love. Due to its thickness, the primer coat will also be very durable, and the paint will adhere much better.
This is one of the reasons why many people choose this brand.
Also, since the product is thicker, you won’t have to apply too many coats. In fact, some projects will only require one layer of the Zinsser product.
Overall, Zinsser is a better product in terms of consistency. It also gets extra points for the fact that it has no bleed-through.
How to Choose Your Primer Type
Zinsser and Kilz are two brands that feature different types of primers, and you should choose them based on the surface you want to paint.
Latex primers, for instance, are great to use for multiple projects, and the cool thing is that you can use them both outdoors and indoors.
What’s even better is they make it possible for the underlying material to breathe since they are vapor permeable.
Some latex primers you can use in this regard include Zinsser Bulls Eye and Kilz Premium.
Shellac-based primers are also great, mostly because they can be used to cover very stubborn and bad odors and stains. But they work only for interior surfaces, and they also tend to be pretty expensive.
Then, you have oil-based primers for wood that can be used both inside and outside. They offer amazing coverage, and they can also seal the surface properly.
So, they are great for exterior wood since this is often exposed to moisture and different weather conditions.
Unfortunately, there are also some cons, such as the fact that they don’t allow breathability, making them a bad option for drywall or plaster. Moreover, they don’t adhere to galvanized metal.
You will have to pick a primer depending on the type of project you are working on. Zinsser and Kilz both have products made for challenging surfaces like masonry and bare metal.
Zinsser features a great Metal Primer if you need to paint rusty or clean surfaces. Then, Kilz comes with a Concrete & Masonry Bonding Primer.
People tend to pick Zinsser primers in general out of the two brands. Still, you need to do your research and choose the one that you think will work best for you.

Which Paint Primer Brand Should You Choose?
Both brands are amazing, but overall, Zinsser is considered the best out of the two. Thus, Kilz will have to make some improvements if they want to achieve the same level of quality.
Zinsser is known and loved for the thick and durable coatings, which will lead to less prep work. It also requires fewer coats. This makes it amazing to use on tougher surfaces as it has better adhesion. So, Zinsser is the more trustworthy brand overall.
You can use Kilz if you are working on a surface that needs thinner primer layers or if you don’t mind some additional prep work. Zinsser offers more versatility. Either way, it’s better to apply any primer than no primer at all.
Thus, Kilz would be alright if you cannot get Zinsser.
Zinsser 123 Primer vs. Kilz FAQs
Here are a few common questions when comparing Kilz 2 vs Zinsser 123.
What Type of Kilz Primer Should I Use?
In order to decide what Kilz primer you should use, you must see what surface you are painting. For instance, you may want to look into KILZ 1 Standard Interior Primer or KILZ PVA Drywall Primer if you need to paint a new drywall.
How Many Coats of Kilz Primer Should I Use?

This will also help hide any flaws in the wall. You can learn more about how many coats of primer are needed on wood for painting.
