What is Drywall Primer?
Primer is necessary to ensure you have an even surface for painting onto your new drywall. Most consider the best drywall primer to be Polyvinyl Acetate (PVA) primer. This primer is made up of the same ingredients that you would find in wood glue. This kind of primer is perfect to be used as a drywall sealer as it performs well on porous surfaces and assists in covering up and nail heads or seams. The primer ensures the surface is even and ready to be painted on. This drywall primer has been formulated to adhere better to the surface than paint adheres.
If you thought you could just apply several coats of paint and that would be sufficient, then think again. Firstly, a lot of paint will go to waste. Secondly, the final layer of paint will be uneven, and your selected sheen will look different over non-taped and taped areas. This will probably occur with each layer you apply, and the results will not last long.
To stop the paint from being absorbed all primer for new drywall will be required. The primer seals the drywall. This will decrease the growth of mold in rooms like the kitchen or the bathroom where there is excessive moisture.

As previously mentioned, one option is to use a PVA drywall primer. This is thanks to it being well-priced and formulated specifically to act as a sealer on drywall.
You can also purchase a primer-and-paint option, which also contains thickening agents. These are referred to as self-priming paints. These products contain PVA and the consistency is much thicker than standard paint, which means it is not necessary to apply many layers. With only two coats you should be able to achieve an even surface.

- Tinted Primer: by adding paint to a high-build primer you can create your tinted primer. The layer will not be the same color as your top layer but will be as close to a match as possible. This means you will only require one layer to achieve an even finish.
- Bonding Primer: this primer offers a very strong bond on both smooth and porous surfaces. You will receive a strong bond and thick coat when applying this primer.
- Acrylic Primer: this is a pricey option, but the expense is worth it. The primer can seal and cover up any cracks and will offer you a smooth, even coat.

Pros and Cons of Drywall Primer
We will be focusing on the drywall sealers and primers which are more commonly used. You have two options to choose from, being a water-based or oil-based product. It is possible to tint a drywall primer so that it can match the paint you have selected to use. Certain paint stores may even offer the service to tint your primer at an added cost.
Purchasing a Drywall Primer
If you know what you need, it is really easy to purchase a drywall primer. So, what should you be looking for? It can all seem a little overwhelming as there are so many different options to choose from. We have put together a list of aspects you should take into consideration when selecting a drywall primer.
Understanding the Purpose
You need to have a clear understanding of what you require the drywall primer to do, to select the correct product. The question you need to ask is, what purpose does the product serve, and is it required? Your requirements might mean that you need to purchase a top-end specialized primer.
Moisture and Stain Resistance
Certain primers offer resistance to moisture and stains – you do not want your work to be ruined because you did not consider this feature. If you are working in a room such as a kitchen or a bathroom, where there is a lot of moisture, you will require moisture resistance.
Water-based primers give off hardly any odor in comparison to oil-based primers. That said you will always need to consult the label, as you can find oil-based primer-sealers which give off no odor and can be used both outdoors and indoors.
The Condition of the Wall
If the wall is very uneven, or has a lot of holes, or may have nails sticking out of it, you will need to look at purchasing a high-build drywall primer. This type of primer covers most flaws thanks to it being much thicker. It offers a more even surface ideal for the application of paint. However, if you have perfectly smooth drywall, you could then use a standard primer. Regardless, it is best to use a good-quality drywall primer.
How big is there an area you will need to cover? Once you have answered this question, you will then have an idea of the volume of primer you will require. We suggest you purchase more primer than you think you will need. You should also look at the size of the product you are buying, as the primer is available in different quantities, from quart- to gallon-sized containers.
If you are working with a budget you might think of purchasing a cheaper primer. Sadly, these products might be of poor quality or unreliable. Rather select a more well-known brand that has received positive reviews. You can save money and time by going with an affordable option.
All-Purpose Primer vs. Specialized Primer
Certain primers have been designed to work on the majority of surfaces, while others can only be used on certain types of surfaces. Consider buying the all-purpose option, as you want to have any go to waste, as leftovers can be used on other projects.

How to Apply Drywall Primer
When it is time to apply a primer for new drywall, it is not necessary to purchase the most expensive option. New walls are normally pristine, with no cracks or holes, or stains and odors. On the other hand, if you are working on existing walls when renovating and the walls are damaged or have stains, it will be necessary to apply a drywall primer. Ideally, you want to use a drywall primer that has stain-blocker features.
Either way, there are some basic steps you need to follow when painting your drywall surface.
The first thing you will have to do is inspect the drywall. Look over the drywall surface carefully and make note of any cracks or holes. You will need to use drywall mud to fill these, and you will then have to use a pole sander to sand the wall to ensure you have a smooth and even surface.
When you have finished sanding ensure that any dust is cleaned away. Vacuum the dust and then using a clean, dry cloth, gently wipe down the walls. Alternatively, you can use a product called Swiffer Sweeper instead. You will be able to use a sweeper for other purposes throughout the home.
Now it’s time to deal with how to prime drywall. Certain people suggest using flat paint as the primer; however, if you choose to do this you will not achieve a long-lasting and smooth finish. You can use a product that is a combined paint and primer but only uses this option if the wall is in pristine condition or new. If you are unsure, rather use a high-quality drywall primer and sealer, as it has been created specifically for this purpose.
Cover the whole wall in primer. You can paint the primer using a brush, which will be able to manage the corners and precision work. To cover the larger area, you can start using a paint roller.
Another option is to spray the primer on, but rather call in the professionals to do this when working with drywall.
It will take between three hours, or as quick as 30 minutes, for the primer to dry. Make sure that you consult the product label for the drying time, as the type of primer and even the humidity can impact the drying time. When the initial coat has dried, you can apply the second coat. Once this coat has also dried you will be able to apply the topcoat.
