An essential first step in any wall finishing project is priming the drywall. Although it may appear like an extra task, ignoring it now could cause issues later on. Priming guarantees that the surface is prepared to receive the final finish, giving you a smoother, more durable result whether you intend to paint or apply wallpaper.
You get control over the caliber of your work and can save costs by priming drywall yourself. With a little perseverance and the appropriate supplies, anyone can complete the simple process without the need for any specialized skills. By sealing the drywall’s porous surface with a high-quality primer, you can stop paint or adhesive from absorbing unevenly.
This tutorial will take you step-by-step through the process of priming drywall, from choosing the appropriate primer to correctly applying it. You’ll be well on your way to having a finish that looks professional and lasts if you heed these tips.
Step | Description |
1. Surface Cleaning | Remove dust, dirt, and debris from the drywall surface before priming. |
2. Apply Primer | Use a roller or brush to evenly apply a coat of primer over the drywall. |
3. Dry Time | Allow the primer to dry completely before proceeding with painting or wallpapering. |
Prior to painting or applying finishes, priming drywall is an essential step that guarantees a smooth, long-lasting, and polished outcome. Applying a primer properly not only improves the surface for paint adhesion but also helps to seal the drywall, averting uneven finishes and moisture damage. With just a little effort and this guide, anyone can easily achieve excellent results when priming drywall on their own.
Why prime drywall
Generally speaking, a plasterboard sheet is not a finishing finish. As a result, it’s typically painted (see How to paint drywall), whitewashed, covered in adhesive wallpaper, or even covered in tiles.
It goes without saying that any surface should be prepared before applying the finishing coat in order to strengthen the final finishing materials applied on top, improve their adherence to the surface, and shield the surface from harmful elements. Plasterboard priming is carried out for this purpose.

Advantages of primer
Frequently, inexperienced interior decorators inquire as to whether priming plasterboard is required prior to painting or wallpapering (see. Can wallpaper be glued to plasterboard without the need for putty?
Priming plasterboard is obviously essential because it gives you the following benefits:
- Strengthen the joints of drywall sheets, thereby protecting their inner surface from moisture, dampness, microorganisms and other destructive factors;
- Strengthen the surface of the entire wall made of plasterboard sheets;
- Increase the adhesive properties of the plasterboard surface and increase its adhesion to subsequent finishing materials;
- Increase the moisture resistance of plasterboard, which is very important in the kitchen, shower, bathroom, toilet and other rooms with high humidity;
- Prevent the process of peeling wallpaper, paint and tile peeling after finishing due to poor interaction of glue / mortar with the surface of the wall made of plasterboard sheets;
- Reduce the consumption of finishing materials, improve the quality of their application and service life.
Primer functions
It is important to consider the multitude of beneficial purposes that priming agents serve when attempting to determine if plasterboard can be primed.
The plasterboard surface gains the following characteristics from the primer treatment:
- Water-repellent;
- Adhesive;
- Penetrating;
- Bioprotective;
- Firefighters;
- Antiseptic.
Of course, drywall primer compounds that are currently available on the market are capable of performing multiple tasks simultaneously or all of them at once. As such, careful consideration should be given to the primer selection.
The best soil mixtures for drywall are acrylic, phenolic, and alkyd mixtures out of all the modifications that are available today. The rest are used for exterior work and are not appropriate for interior decoration.
By using drywall primer that is properly chosen, you can prevent unpleasant situations like paint that is redundant into the material or unevenly applied to the surface, which greatly diminishes the finish’s aesthetic indicators.
Furthermore, wallpaper glue can oversaturate the drywall sheet’s material if it is applied directly to the drywall without first priming it, which will cause the sheet to break apart when the wallpaper peels off. This will necessitate replacing the drywall, which is the foundation of the finish, in addition to the wallpaper.

- Universal;
- Harmless;
- Suitable for any type of material and surface, dries in just a couple of hours;
- Applied both before and after puttying.
It should be considered that during priming work, the phenol in its composition may be toxic to those present in the room.
Which primer to give preference to
When asked which primer is best for priming drywall, we can advise you to consider the characteristics of the finishing material specifically.
- For light wallpaper and painting, a surface penetration primer mixture with low or medium adhesive properties is suitable;
- To fix heavy wallpaper or tiles, it is better to use a primer with maximum deep penetration, which increases the adhesive properties of the plasterboard.
- For rooms with high humidity, a moisture-resistant primer is suitable, creating water-repellent qualities of the surface.
Kindly take note! Standard plasterboard is typically primed with a universal acrylic primer mixture. It maintains the room’s microclimatic characteristics by having a high penetration rate into the material’s pores, producing excellent adhesive properties, not containing any toxic materials, drying quickly, and good air passage.
Even glossy surfaces can benefit from the application of such a primer.

Now that the drywall interior decoration is complete, the only thing left to do is learn how to prime drywall. It’s very simple to perform this procedure with your hands. To achieve the best results, you will need to buy certain tools in addition to the primer mixture itself.
Every aspect of choosing and applying the primer mixture is demonstrated in detail in the drywall priming video.
Tools and materials
The following working inventory and supplies are needed for drywall primer before painting, applying wallpaper, putty, or installing tiles:
- Roller. A common tool used in painting, but with an average pile length. The threads of the latter, by the way, should not come out if they are pulled with force. For convenience and speed of processing, it is better to use a roller on a long handle.
- Brush. It is better to take two types of brushes – a fly brush and a hand brush. The first can be used to process a large surface area, the second is designed for applying the mixture in hard-to-reach places.
- Container. A tank, bucket and other container of suitable volume for placing the priming solution in it.
- Tray with a ribbed bottom. Specially for priming works, special trays are sold that have a ribbed bottom surface – for better squeezing of the roller.
- Primer. The amount of mixture is selected based on the area of the surface to be treated. Usually, the instructions on the packaging contain this information.
- Personal protective equipment (glasses, mask, gloves).

Stages of applying primer to drywall
Primer should always be applied before puttying, whether painting drywall, tiles, or wallpaper. However, for improved fixation, you may choose to apply a coat of primer after the puttying is finished.
Kindly take note! Thoroughly cleaning the drywall of construction and household dust or dirt is necessary before you begin priming it. Additionally, you must confirm that all fasteners are fitted and secured.
The following steps can be used to illustrate the process of priming drywall:
- Dilution and preparation of the mixture in a container of suitable volume according to the instructions;
- Transfer of the finished solution to a special tray;
- Dipping the roller and applying the first layer to the drywall. It is necessary to monitor the uniformity of the solution application. The entire surface of the drywall must be treated;
- Drying the surface;
- Puttying (see. DIY drywall puttying);
- Grouting and leveling the dried putty;
- Removing dust and dirt;
- Finishing priming over putty.
The priming of drywall is a crucial stage that must be considered if you want a seamless and long-lasting finish. It guarantees a consistent color, improves paint adhesion, and may even extend the life of your walls. Making the effort to apply primer correctly will have a big impact on the outcome.
You obtain control over the work’s quality and can save money by doing it yourself. Without hiring a contractor, you can accomplish professional-looking results with a few basic tools and a little perseverance.
Recall that the most important thing is to apply the primer evenly and let it completely dry before painting. Although it may seem like an extra step, doing this will ensure that your walls continue to look fantastic for many years to come.
