Buying Guide


Water-based, oil-based, and shellac-based primers are among the options available to you.

It is possible to use a water-based primer both indoors and out, making it a versatile product. Cleanup is a breeze because of their low VOC content. In terms of dealing with tenacious stains, however, they are no match for oil- or shellac-based primers.

Oil-based, or alkyd, primers, can be used on a wide range of interior and exterior materials, including wood, stone, and metal. Water-based ink stains, in particular, are easily removed using oil-based sealers. They may also be used on porous surfaces like wood, which is why they're so popular.

In the majority of cases, shellac-based primers are used inside. They are the best equipped to deal with fire and smoke damage and odors. Shellac is the primary ingredient in most products we prescribe today. On the other hand, they're pricey and time consuming to maintain.


Use a primer with good adhesion to avoid peeling paint or even the entire wall if necessary. Notably, certain primers stick better to specific surfaces than others.

The best oil-based primer, for example, can help seal the porous surface of bare wood, but drywall is not suggested for their use. Bonding primers are a necessity when working with glossy surfaces. Meanwhile, metal should be primed using an oil-based primer that is resistant to rust. Remember that compared to latex primers, oil-based primers produce higher volatile organic compounds (VOCs).

Stain coverage is one of the most significant considerations when selecting primers and sealers. There are a few things to keep in mind when looking for an effective primer: If the paint is of poor quality, it may be applied too thinly, allowing the stain to show through the layer over time.

Dry Time

In order to avoid having to wait too long before painting over a primer, it should dry quickly. Oil-based primers might take up to three hours to cure before they can be recoated with paint, although latex primers dry quickly. The indicated drying time of 30 minutes to an hour may or may not be accurate for some goods. Drying time for even the best primers might take as long as 40 hours.


What should you anticipate to pay for such a product? Is it a one-time expense or will it come up again?

There are several different ways to get a good deal on an odor-killing primer. Lower cost, superior build quality, or increased durability are all possibilities. Our top options for the most effective odor-killing primer on the market will be discussed in detail in the sections that follow. There is a lot that consumers need to know about odor-killing primers, and we'll cover it all.


Odor killing primer is no exception to the "people get what they pay for" rule. Depending on the materials used in the construction, there can be a significant difference in the durability of the product. Is it really a good deal to save $100 on an odor-killing primer that only lasts a month?

Look at the $50 difference in price between this and an odor-killing primer that fades out in a year or two. Over the long term, most individuals believe that the second alternative is a superior deal. Consider the length of time you intend to use the odor-killing primer before purchasing it. Then read customer reviews to see how long you can anticipate it to last.

Consider Where You Purchase 

People are increasingly purchasing odor-killing primer online rather than visiting a storefront. Many brick-and-mortar stores might be complicated when it comes to their models, price, and types, which is why internet shopping is becoming more popular.

Customers can't have the same hands-on experience with an online odor eliminating primer as they can in a shop, but many brands offer extensive free trials. If you're not satisfied, you can return the odor-killing primer for a full refund.

As a result, many online odor-killing primers are cheaper than their in-store counterparts because they have fewer administrative costs and have eliminated the middlemen. If you're making a purchase on the internet, be careful to ask if shipping costs are included. While many new businesses provide free shipping, this is not always the case.


In order to mask the smells, you consider purchasing primers. But what if the primers themselves smell bad? Most primers on the market have a strong and unpleasant odor, which is a severe issue. Fortunately, low-scent primers are available, but they can be pricey. A well-ventilated space will help the stench dissipate faster.


Does KILZ primer kill odors?

When it comes to sealing out the smell of smoke, fire, food, and pets, KILZ primers perform the same thing as Zinsser. However, you should be aware that KILZ primers have a strong scent.

Which is better, KILZ or Zinsser?

This is a contentious subject with many opposing viewpoints. Some people swear by Zinsser primers, while others swear by KILZ primers for their superior odor-killing abilities. Zinsser primer, on the other hand, provides superior coverage, while Original KILZ enables more bleed-through in a test on the identical two walls. Those who compare these two primers will see the difference.

Is Primer smell harmful?

VOCs are frequently seen in the typical paint vapors. Inhalation of volatile organic compounds (VOCs) can make you queasy and disoriented, while skin exposure might cause irritation. When painting indoors, even if your house has a decent ventilation system, you need to take measures. Stay away from freshly painted rooms if you don't want to endanger your health.


The use of primers and paints goes hand in hand almost without fail. A decent primer is essential if you want a nice finish layer of paint. After reading this guide, you should be able to pick the best odor block primer for your needs. High adhesion, excellent stain coverage, and a quick drying period are required.
