Adding primer to your next paint project can greatly improve the quality of the final coat of paint. Not only does primer help paint adhere to the wall, but it can make the paint look better as well.
However, not all primer is created equally. Some brands and formulations are great, and others don’t work as well, leaving you with the feeling that you got ripped off. This risk is much greater when shopping online, as it can be harder to get a feel for the product’s quality.
We want you to be confident when you shop online, which is why we’ve assembled these reviews of some of the best oil-based primers of 2019. We also created a buyer’s guide designed to help you learn about primers so that you know what you want in a primer before you go to buy.

The KILZ 10902 Interior Oil-Based Primer is the standard bearer for interior priming projects. It’s an old brand used by professionals for a long time, and it has continued to get better over the years. In its modern integration, it does a fantastic job of covering stains. If you have wall damage due to leaking water, this primer does a great job of making your final coat of paint look the same on damaged and undamaged wall. But, not only does it look good, but this primer also blocks smells.
Water-damaged materials can smell awful, but this formula also blocks smells from pets and smoking that have seeped into the walls over time. This primer dries to the touch in 30 minutes and is ready to be painted over in as little as an hour, though you get the best result if you let it dry completely, which takes a day or two. It’s also compatible with most wall surfaces, including masonry, brick, and painted metals with which other primers struggle. While it does have strong fumes until it dries, you’re getting the best primer on the market when you buy this brand.
True Value HP208-QT Exterior Oil Based Primer is an excellent oil-based primer that is designed for the rigors of working outdoors. Any paint or paint-like product that you use outdoors is going to be subject to not only potential damage from water, but also must deal with the sun’s damaging rays. And, this brand lives up to those expectations, performing well in all outdoor applications.
This formulation also works well on raw basement floors, which is uncommon among primers. The frequently damp, dirty conditions of basements is no match for this primer’s resistance and durability, even before paint is put down. Plus, it has the added bonus of helping your paint stay a consistent color, which is good for situations where there’s damage, even if that damage wasn’t your fault. However, this brand is very expensive, even among primers, so while it works very well, it’s not going to fit into everyone’s budget, and that’s what drops it out of first place.
The Zinsser 03504 Interior/Exterior primer is some of the best on the market for beginners. First, it’s good for both interior and exterior application, so if you’re not sure where your next project will take you, this formulation is a good choice. It also adds a bit of shine to whatever pain you end up using, so it makes your job have a bit of extra pop, even if you’re new to this kind of project. It also sticks well to most surfaces, even if they’re poorly-sanded, or not sanded at all, which makes them great for beginners.
Even better, it’s reasonably-priced, which in the world of primers is saying a lot. You’re getting really good value with this formulation, so you don’t want to miss out on this opportunity for your next project. The one knock on this primer is that it isn’t mold or mildew-resistant, which means that you’re going to have to use an additive or buy a different brand if you’re in an area where that is a concern. Overall, you can get this primer for a great price, but given how easy it is to use, it’s also the best primer for beginners.
The Rust-Oleum Corporation 03609 has all the features and flaws that you would expect from aerosol-based primer. The good parts include the fact that it comes in a spray can, which means that application is going to be generally easier than using a brush and typically will involve less clean-up, too. If you’re applying primer to in irregular object with a lot of nooks and crannies, then an aerosol spray primer is probably the right direction to go. This brand also comes with a powerful spray mechanism, which means you can spray vertically, which isn’t possible with all brands.
However, you’re getting a limited quantity with a spray can, and you must replace the can each time you run out, which means you’re paying for spraying mechanisms each time that you wouldn’t pay for if you had bought a regular can. There’s also the risk of over-spraying onto things behind or beside what you’re priming, so you need to be careful and cover things you don’t want to be primed. While there are some upsides to a spray primer, it’s not going to be the best choice for most large-scale projects, which sinks it to the bottom of our list.
We hope that our reviews have given you some starting ideas about what you ought to be looking for when you go to shop for primer. If you still have questions, that’s okay. This buyers’ guide is designed to give you the lowdown on primer, so if even if you’ve never used primer before you can know everything to consider before you go to buy. Or, if you’re an experienced painter, this guide should serve as a good refresher course so that you make sure you haven’t forgotten anything important.
One of the best features that you can find in modern primer is the ability to cover up stains in the base material. In theory, paint is supposed to cover up stains, but paint, and especially cheap paint tends to look different when put on different materials. Sometimes the stains “show through,” since the spots where they look less glossy or have a slightly different color than the rest of the wall. Consequently, finding a primer that does a good job of covering up stains by providing a consistent base for the paint you use is important.
You should also keep in mind that some stains should be removed instead of covered up. Primer can do a lot of things well, but it can’t repair structural damage. If your drywall is still wet, covering it up with primer and paint can lock in the moisture and lead to further damage. And, water coming from behind will cause your paint to seal and run, so make sure that you take care of severe problems before starting your paint job.
Smell is another important factor that you should consider before embarking on your paint job. Some primers can lock in smells that have accumulated in your walls, especially if those walls are drywall. If you’re in a house that used to have smokers or pets in it, then smell-fighting primer can be a lifesaver. In these instances, you must make sure that the smell is coming from the walls. If it’s locked into the carpet, then painting the walls isn’t going to do much good.
You also must consider the smell of the primer itself. Painting or using primer is a smelly task in most instances. If you’re especially sensitive to smell, you may consider purchasing a low-smell formulation. That may cost you more, but it can be worth it. In some instances, outdoor primer would work just as well indoors, but it’s labeled as outdoor because its fumes are overwhelming in an enclosed space.
You also want to make sure that the area in which you’re working is properly ventilated. Opening windows while painting inside, or moving portable projects outside can be a great way to reduce the amount of fumes that you breathe in.
How long your primer takes to dry is an important consideration. Different brands have different drying times, which means that the brand you buy should be somewhat dependent on the amount of time that you have to finish the project. Some companies make primer that they claim dries in as little as 30 minutes or an hour. This is only partially true. You can add a layer of paint after just 30 minutes or an hour, as the primer will be dry to the touch and also dry enough to hold paint.
However, even with quick-drying primer, it’s generally better to wait 24 to 48 hours after you apply the primer to let it dry completely throughout. That extra time generally results in a better bond between the paint and the primer and the primer and the wall, and also generally makes the whole project look a tad better.
Every primer has a slightly different effect on the paint you later apply. While all primers are designed to keep your paint firmly bonded to the wall or other surfaces, some can change how it looks as well. Some primers make the final paint you apply look glossier or more matte, so it’s important that you take the time to research what effects specific primers have on paint.
You’ll also want to keep in mind the fact that some primers do a better job than others at covering up stains. If you’re dealing with stains, make sure that you get a primer that is meant for stain-covering. Otherwise, you’re probably going to have to paint over everything again shortly.
There are a lot of brands of primer on the market, and a lot of people make the mistake of buying the cheapest variety they can find. However, not all primers are created equally, and there’s a chance that you’re cheating yourself out of a good deal by being cheap. Remember that you have to look at your walls every day, and if your primer doesn’t live up to your expectations, you’re going to be constantly reminded of that fact. Make sure that you get a primer that covers your needs, even if it costs a bit more.
The KILZ 10902 Interior Oil-Based Primer is one of the best primers on the market and rises to the top of our list due to its smell-blocking properties and compatibility with most wall surfaces. True Value HP208-QT Exterior Oil Based Primer comes in second because of how well it works but is kept out of first by its very high price. The Zinsser 03504 Interior/Exterior primer provides the best value and is also the best for beginners due to its low price and versatility. The Rust-Oleum Corporation 03609 is a good spray primer but falls short of the value that you can get from traditional primers.
Hopefully, our reviews and buyer’s guide have helped you learn about primer and what you should be looking for when you buy. You’re now ready to find the perfect primer for your next big project.
