Some essential qualities in the best odor block primer you should consider are as follows:
There are several types of primers for you to choose from, including water-based, oil-based, and shellac-based.
Water-based primers are all-purpose products that are suitable for both outdoor and indoor applications. They have little to no VOC and are easy to clean. Nonetheless, they cannot compare to oil-based or shellac-based primers regarding the efficiency when dealing with stubborn stains.
Meanwhile, oil-based, also known as alkyd primers, are a good option for a wide array of interior and exterior surfaces. Oil-based sealers work like a charm against odors and stains, especially water-based ink stains. They are also highly recommended for porous surfaces such as wood.
Shellac-based primers are generally applied indoors. They can handle damage and odors from fire, smoke best, etc. Most products we recommend today are shellac-based. But on the negative side, they are expensive and difficult to clean.
We highly advise that you use a prime with high adhesiveness to prevent peeling off the paint or even your walls in worse cases. Note that different primers adhere better to certain surfaces.
For example, oil-based primers can help seal the porous surface of bare wood, but they are not recommended for drywall. With glossy surfaces, bonding primers are a must. Meanwhile, metal should go with a rust-resistant oil-based primer well. Do not forget that oil-based primers tend to produce more volatile organic compounds – VOCs compared to latex primers.
One of the most important features when choosing primers/ sealers is the stain coverage capabilities. Simply put, a good primer must be able to hide the stains well. Cheaply made paints may give a thin application, which let the stain show through the coat after a while.
The best primers should dry fast so that you do not need to wait for too long before painting over them. In general, latex primers are the quickest to dry, whereas oil-based products take up to three hours before they can be recoated with paint. Keep in mind that although some products are advertised with a drying time of 30 minutes to one hour, this is not entirely true. Even excellent primers need up to 40 hours to dry off completely.
You want to buy primers to hide the odors, but what if the primers smell worse? That is a serious problem with most primers on the market since they emit a strong and nasty odor. Fortunately, there are low scent primers that you can consider, but they may be more expensive. Also, make sure your room is well ventilated to let the smell go off more quickly.
Are you searching for an all-around primer that covers everything unwanted to leave your walls spotless? This Zinsser Rust-Oleum shellac-base primer is at your fingertips. It works to block stains as well as kill existing odor from pets and smoke permanently.
The best thing about this primer is probably how flexible it is. To be specific, it can stick and hide stains on virtually all surfaces, from sheetrock to wood. And as mentioned above, it is the best primer for concrete floors. Its coverage is perfect, just one application is all that you need.
Another reason why the Zinsser Rust-Oleum 01008 is widely loved must be the quick drying time. It dries really fast, which takes only 45 minutes before you can recoat.
On the negative side, this primer is designed with a narrow spray. If you are not careful, you may waste much paint, and extra sanding is needed.
This is another odor killing primer by Zinsser. Like the previous product, this primer is synthetic shellac-based. It combines stain-blocking capability, low odor, and fast drying time in a single unit.

There are hardly any complaints on this primer’s performance, except for a few feedback that you need to apply many coats to hide the stains completely. This may depend on how stubborn the stain is.
Coming from the same brand as the Rust-Oleum 01008 and 271009, the 00904 model is also a shellac-based primer and sealer. It adheres well to most surfaces and can hide even the toughest stains.
What sets this pigmented primer apart from the competition is its consistency, much like thick milk. When you apply it on the walls, the paint rolls on smoothly and sticks well.
Since the shellac is suspended in alcohol that evaporates quickly, you can expect the primer to dry fast. The alcohol smell will wear off once the primer dries to the touch.
Most negative feedback is related to the fact that the primers arrived dented and damaged. If you encounter this problem, feel free to contact the manufacturer for a replacement or a refund.

A: Generally, the oil primer will stop smelling after about 3 to 4 days, depending on the ventilation system of your house.
