A drywall primer is a layer of product that is applied to the wall just like paint. It is applied directly to raw drywall to seal it and create a smooth surface on which you can then apply finishing layers of paint. You can also apply it to older drywall when you want to change the color of the wall and improve the finish.

When to Use Drywall Primer
Drywall primers can be used for a number of reasons. It is designed to seal the surface of the drywall and create a base that paint can go directly on top of. As drywall has a porous quality, if you were to paint directly onto it, then the new drywall would absorb the paint, meaning you would need a lot of layers of paint to get a reasonable depth of color. Getting a smooth finish on the paint would also be unlikely due to the texture of the drywall.
A drywall primer will seal the tiny holes in the new drywall and create a film over the whole surface. This allows the paint to cover much more easily and will make for a much better finish. It will also seal tape joints on new drywall and give a seamless look. Drywall primer can also be used on older drywall that has suffered from stains, such as water damage stains, mold stains, or stains caused by marker pens. A stain-blocking drywall primer will prevent the stains from showing through and make the drywall look new again. When thinking about when you should use drywall primer, the simple answer is every time you use drywall! Drywall primer is an essential purchase for drywall projects, which will give you the best finish and save time and money.
Benefits of Drywall Primer
Professional Smooth Finish
If you have installed new drywall, then using a primer is the best way to get a professional finish. Drywall primer will ensure a smooth surface that is non-porous to allow your paint to glide right onto.
Use Less Paint
If you don’t use a drywall primer on new drywall, then you’ll find that your paint absorbs into the drywall, and you’ll need a lot of coats to achieve the color and finish you want. This not only takes up a lot more time, but it also means spending more money on a larger quantity of paint. A drywall primer will seal the drywall and create a neutral-colored surface which is an ideal base for paint. Most good quality paints will only need one or two coats on top of the primer, and in many cases, you can opt for a more budget-friendly paint because the primer is doing most of the work when it comes to the finish.
Some drywall primers have a stain-blocking ability, which is great if your drywall is stained and you want to bring it back to its former glory. Anyone who has tried to cover stains with paint will know that over time the stain will show right through. Using a drywall primer intended for stain blocking will prevent this issue and ensure a clean, stain-free surface.
Improves Paint Adhesion
Drywall primer improves paint adhesion, so that even lower quality paints will stick well to the primed drywall and cover more easily. This means that painting becomes a breeze, and you won’t have the annoying issue of more paint sticking to the roller than the wall.
Seals Joins and Surfaces
The drywall primer seals the surface of the drywall, as well as any taped joins. This creates a smooth surface for the paint to be applied on top of.
How to Choose the Right Drywall Primer
To find the right primer for your project, you’ll need to consider the following points.
State of Drywall
The condition of your drywall can dictate which primer you need. Some primers are designed specifically for new drywall, while others can be used on any type of drywall.
If you are using a paint sprayer to apply your primer, then you’ll need to choose a water-based formula. This is because it cleans up more easily if you aim off target and also because oil-based primers are too thick to work well in a sprayer. If you intend to use a roller or paintbrush, then you can use any type of drywall primer.
The type of paint you intend to use to finish your walls can affect your choice of primer. Latex or oil-based paints work best with latex primers. Some people even choose to use their primer as both a base and final coat if the primer has a nice finish, which is typically achieved with latex primers that have a very slight sheen.
Water-Based vs. Oil-based
Water-based drywall primer is generally more preferable to oil-based primer for interior applications because it has a low odor and dries quickly. Water-based primer is also easier to clean up, so it won’t ruin your paintbrushes or paint rollers if you don’t have any paint thinners handy to wash them with.
