Yes, Kilz is an excellent and widely trusted primer for drywall. It helps seal porous surfaces, prevents paint from soaking unevenly, and provides a great base for your final paint coats.
KILZ® Drywall Primer & Sealer seals new uncoated drywall which helps achieve a uniform professional quality finish in less coats. It dries fast (ready to paint over in 1 hour), easy to clean-up and ready to apply with standard applicators.
The best primer depends on the condition of your drywall. For fresh, unpainted drywall, a PVA (polyvinyl acetate) primer is the industry standard. If you are painting over repairs, stains, or old surfaces, a high-quality multi-purpose acrylic primer is your best option.
Its thicker high hiding formula hides surface imperfections and prepares the surface better for painting. Use on interior and exterior surfaces including woodwork, drywall, plaster, paneling, masonry, brick, painted metal and properly prepared glossy surfaces. Works with oil and water-based paints.
Skipping primer on bare drywall causes paint to absorb unevenly, resulting in blotchy finishes and flashing (inconsistent shine). It also causes poor adhesion, leading to peeling, and forces you to use significantly more coats of expensive paint.
Some drywall finishers add a small amount of dish soap (like Dawn) to drywall mud as a workability hack. They do this to act as a surfactant, which reduces the surface tension of the mud.
No, you do not need to use a dedicated primer product if you plan to use a paint-and-primer ""All-In-One"" product. However, professional painters looking for a high-grade finish will always use a dedicated primer as the first coat on fresh drywall or raw wood.
So, how many coats of primer will you need to coat your drywall? When you're prepping your drywall, you can generally expect to add a minimum of two coats of latex primer. In some circumstances, two coats of primer might even be insufficient to get a bold, even result from your paint job.
Kilz and Zinsser are the two heavyweight titans of the primer world, but they excel in slightly different applications.
To hide drywall imperfections, use a high-build primer. These primers are thick, high-solids formulas designed to fill minor pinholes, sanding grooves, and texture differences to create a uniform surface. Standard PVA primers will not hide flaws and are only for sealing new drywall.
For new drywall, the most professional and durable method is to spray and back-roll the primer. This means spraying the primer on quickly with an airless paint sprayer, followed immediately by rolling it out (back-rolling) with a 3/4-inch nap roller to push the primer into the pores of the joint compound and paper.
Priming your walls creates a smooth, uniform base, ensuring your topcoat adheres properly and displays its true color. You should always use primer if you are painting new drywall, making a drastic color change, or covering stubborn stains like water or smoke.
As you might guess, a primer that bonds peeling paint is not suited for use on substrates such as glass, glazed brick or Kynar.
Although they are more expensive than PVA primers, drywall primers are better for patches because, in addition to working on bare drywall, they also can be used over previously painted areas. These products contain more pigment than PVA, so they cover better and can be tinted for dark topcoats.
When comparing Kilz vs. primer, it helps to know that Kilz is simply a brand name for a line of high-performance primers. While generic primers prepare standard surfaces for paint, Kilz is highly specialized and generally used to block stubborn stains, seal in heavy odors, and prevent moisture damage.
Though the name itself is misleading, KILZ paint and primers do not actually 'kill' mold. But it will prevent mold. The brand does well to kill a stain's ability to show through the final coat of paint by sealing over the stained surface with an impermeable interior barrier.

The best overall primer for interior walls is KILZ Premium High-Hide Latex or Zinsser Bulls Eye 1-2-3 for general use, providing excellent adhesion and hiding power. For sealing tough stains (water, smoke) or odors, KILZ Original Oil-Based or KILZ Restoration are recommended.
Our most technologically advanced paint and primer in one, KILZ® Tribute® is 100% acrylic, low VOC, and offers both excellent stain-blocking performance and exceptional durability.
Some people add a small amount of dish soap to drywall mud to reduce surface tension, which helps release air bubbles and create a smoother, more even finish, especially when applying the final "skim coat"; however, this practice is not recommended by professionals as it can potentially weaken the adhesion of the mud ...
Skipping primer on bare drywall causes paint to absorb unevenly, resulting in blotchy finishes and flashing (inconsistent shine). It also causes poor adhesion, leading to peeling, and forces you to use significantly more coats of expensive paint.
Two common mistakes made during drywalling are improper joint compound application (such as applying it too thickly or not feathering the edges), and failing to stagger the seams across different studs, which weakens the wall and increases the risk of cracking.
If you paint directly over unfinished drywall, you will get uneven absorption, flashing, visible seams, and a rough finish. Paint is not a substitute for proper drywall finishing. Now let's break down what “unfinished” really means and what happens if you skip steps.
Apply drywall primer: Use a roller for wide areas and a brush for corners and edges. One even coat is usually enough for standard walls. Let it dry fully: Don't rush this part. Check the product label for drying time and make sure the room is well-ventilated.
Painting a wall without primer often leads to poor paint adhesion, uneven color, peeling, and the need for extra coats of paint. Primer acts as a foundational "double-sided tape" and sealer, so skipping it can result in an inconsistent finish and a drastically shorter lifespan for your paint job.
