Fresh drywall is very dry and can soak up expensive paint like a sponge. It can also make it difficult to drag a paint brush or roller across the surface for pro-level painting. However, drywall primers can seal those pores and allow tools to glide across the surface, resulting in a better-looking finished product.
Just as it’s important to prime fresh drywall, it’s also crucial to purchase high-quality primer that will seal and fill small holes and pores, creating a uniform surface for paint. But how would a shopper know what to look for in the best drywall primer? Keep reading to find out.

Types of Primer for Drywall
Primer is primer is primer, right? Not exactly. There are lots of different types of primers, and they’re not all ideal for any job. The following sections include primers that a DIYer could use, with some tips on when they should (or shouldn’t) use certain types.
Oil-Based
Oil-based primers are excellent for covering stains and sealing wood, but they’re not always ideal for drywall. They will seal the surface, but oil-based primers contain high levels of VOCs (volatile organic compounds) and they don’t accept latex paint well. However, they’re a good choice for priming drywall before wallpaper or paneling.
Water-Based and Latex
The terms “water-based” and “latex” describe the same primers. Most drywall primers are water-based products, and there are a lot of benefits to these primers. First, they’re low-VOC, so breathing around them is safer than oil-based primers. Also, they’re inexpensive and spread easily. They seal fresh drywall well, and they’re a great base for latex paints.
Polyvinyl Acetate (PVA)
Polyvinyl acetate (PVA) primer is the best primer for new drywall. This primer seals the pores of drywall surfaces quickly and easily, and it’s also highly sandable, so it is simple to fine-tune the surface with a sanding block or stick after a primer coat. Since PVA primer is water-based, it’s an ideal base coat for latex paints; it also emits low levels of VOCs.
Shellac
For stained drywall, there’s always a shellac-based primer. These primers cover stains well, dry relatively quickly, and leave behind a tacky surface that grabs paint. Shellac primer serves as a solid base for oil and latex paints, but these primers often contain high levels of VOC compared to latex or PVA primers.
What to Consider When Choosing the Best Drywall Primer
Knowing the different types of primer is a good start, but choosing the best drywall primer requires a bit more background. Below are some of the most important considerations to keep in mind when comparing drywall primers. Some shopping considerations will apply more to certain types of primers than to others.
Drying Time
Drywall is a very dry, porous surface and can quickly soak up any coating applied, resulting in faster drying times. However, some drywall primers—or just primers in general—dry at different rates, which could be a factor when shopping. Water-based primers dry relatively quickly, while oil-based primers take much longer.
If the project needs to go from drywall to finish coat in a weekend, go with a fast-drying primer. A good rule is to look for a drywall primer that states that it’s top-coat-ready in 1 hour. This time frame will allow the painter time to coat the room with primer and switch almost immediately to painting, maintaining a speedy workflow.
VOCs and Odor
Paints and primers contain volatile organic compounds, or VOCs, and they’re emitted through noxious gases. These gases contain chemicals that have varying short-term and long-term effects on a person’s health.
Oil-based and shellac primers are typically heavily laden with VOCs, which makes it dangerous to work with them in small rooms with poor ventilation. Should DIYers choose one of these primers, they should open windows and use fans to circulate the air out of the room. They should also wear a respirator mask.
For those who would prefer a potentially less dangerous priming experience, go with latex or water-based primers. These primers contain some VOCs, but at much lower concentrations. Those who are particularly sensitive might still prefer to wear a respirator and open a window.
Moisture and Stain Resistance
In some environments—such as in a bathroom or another damp space—a DIYer might need to protect the drywall by sealing against moisture. When this is the case, shellac and oil-based primers are often the most effective, though some latex primers are suitable for damp applications. Just be sure to check the manufacturer’s label.
Much of the same information applies to hiding stains. Shellac is excellent at hiding existing stains on drywall, and oil-based primers also are suitable for hiding stains. However, certain water-based primers are also up for the task, though basic PVA primers are not. Check the manufacturer’s label to ensure that a specific primer has stain-hiding properties.

How We Chose the Best Drywall Primers
Putting together a list of the best drywall primers was no small task. After all, not all primers are equal in quality or capability, so it’s important not to paint them all with a broad brush.
First, we relied on our own experience with painting projects to consider the things we look for and look out for when choosing primers. Next, we performed extensive product research on drywall primers that met those needs and compared their coverage, dry time, and price. Anything we felt didn’t offer enough value, we tossed aside.
Finally, we took a look at the remaining drywall primers and assessed them for their strengths and weaknesses. By that point, we had a list of the best drywall primers.
Tips for Using Drywall Primers
The following priming tips will help with most drywall projects.
For best results, sweep the drywall surface with a brush to remove any sanding dust that might lay on the surface. While the primer can blend this dust in, the primer won’t flow as far, and some areas can appear thicker than others.
If the weather is humid, primer will take longer to dry. Promote fast drying by turning on a ceiling fan or positioning a box fan in the room to circulate the air.
It’s not necessary to be overly exact while priming, but it does help to cut in along the ceilings and corners. With about 6 inches of painted surface to overlap, the roller won’t bump into the ceiling or adjacent wall and create high spots.
- Brush the drywall surface with a broom to remove sanding dust before priming.
- Turn on a ceiling fan or box fan to promote faster drying in humid weather.
- Cut in along the ceilings and corners to prevent high spots.
FAQs
If your head is still spinning with all that information about the best drywall primers, don’t fret. The following sections include some common questions about drywall primers. Be sure to check for an answer to your question listed below.
Q. Do I need to apply drywall primer before painting?
Yes. If you don’t prime first, the drywall will soak up the paint and result in an uneven, dull finish. Priming the drywall first will leave an even finish and allow the painter to stretch a gallon of paint further.
Q. How long does it take for primer to dry?
Shellac-based primers can dry very quickly, often in just 20 minutes or so. Water-based primers might take 30 to 60 minutes, and oil-based primers can take even longer. Be sure to check the stated drying time and ready time to top coat on the product instructions.
Q. How many coats of drywall primer do I need?
In most cases, one coat of drywall primer is all that is necessary. However, how many coats are actually necessary depends on the condition of the drywall, especially if there are stains and other discolorations.
Q. Can I tint drywall primer?
Most water-based drywall primers are tintable, but it depends on the specific product.
Q. Are there any differences between drywall primer and paint primer?
Drywall primer is specially designed for drywall. It contains the same chemicals as a typical white glue, and it seals the pores without a heavy coat. Paint primer can also seal the pores, but it’s often thicker and more expensive.
Q. Can I use drywall primer on wood?
Standard primers are a better choice for wood. They’ll adhere better and promote a better finish in the long run than a standard PVA primer.
