Primer application is an important step that is frequently missed when starting a painting project. Primers are essential for ensuring that paint sticks to the surface correctly and leaves a smooth, long-lasting finish. However, it’s crucial to know how much primer you’ll need for your project in order to get the best results. Depending on the kind of primer applied and the type of surface being painted, this can change.
Applying the proper thickness of primer to a given area is just as important as covering it, in order to achieve the best possible results. Primers will absorb more from porous surfaces—such as freshly installed drywall or bare wood—than from previously painted or sealed surfaces. This means that in order to prevent running out of supplies or wasting money, you’ll need to modify your calculations appropriately.
We’ll guide you through the process of figuring out how much primer is appropriate for your project in this article. To demonstrate how to precisely determine the amounts and usage of various primers per square meter, we’ll offer examples. You can make sure that your painting project gets off to a strong start and results in a more polished and durable finish by being aware of these principles.
Whether you’re a professional painter or a do-it-yourself enthusiast, knowing how much primer to use will save you money, time, and frustration. Let’s examine the main variables that affect primer consumption and learn how to confidently estimate your needs.
What affects the consumption of primer
The following are the primary factors influencing primary consumption:
- The nature of the surface;
- Composition and manufacturing company;
- The presence of dyes, glue, other additional materials in the composition;
- The temperature regime in the room, and outside the window.

These are not the primary variables that can alter the composition of the amount consumed. The methods and instruments used for application have an impact on consumption. When applying composition with a roller, for instance, the consumption is significantly higher than when using a sprayer.
Primer consumption rate per 1 m2
As was previously mentioned, the surface that will be covered affects how much primer is used. There will be distinct consumption for the floor, walls, and ceiling, respectively. The composition and the manufacturer’s business may also contribute to an increase in composition consumption.

The surface structure is what matters most when purchasing a primer. The composition of intense penetration with adhered adhesion characteristics is obtained for a rough surface.
For every square meter, one kilogram of primer is used on average.
The number of primer layers required must be determined in order to determine primer costs.
- For a surface, stubble density and porosity, a universal primer is used.
- To take into account it is also important what the surface will be covered after the primer.
- By comparing all these factors, you can calculate the soil consumption indicator closest to reality.

The average composition consumption for the surface is provided by the manufacturer in the instructions, which is the primary source of information regarding composition expenditure. Details are provided regarding the best surfaces to use, the best methods to employ, and the tools to use for the job.
Standards for surface flow consumption:
- The nature of the surface;
- Surface porosity;
- Manufacturer"s indication;
- Type of finish coating;
- The number of layers of primer.
Varieties of soils, their consumption by 1 m2
On store shelves, there are numerous varieties of soils with various compositions produced by various manufacturers. The brand and composition will alter both the consumption and the usage instructions.

Concrete contact
Primers have a high penetration rate and increased surface adhesion; they are used to prepare concrete surfaces.
Plot concrete contact
This is a crucial factor for concrete surfaces because concrete does not absorb moisture well.
- The primer for concrete is quickly absorbed and dries, which allows us to significantly increase the process of work, and to arise to the coating with the next layer.
- The primer "concrete contact" forms small roughness on the wall surface, forming the best adhesion to the next layer, whether it be paint, glue, etc.D.
- After covering the surface with a primer on it, you can mount a tile, tile and other decor elements.

200 to 500g of primer can be applied per square meter, depending on the application method (roller or sprayer).
A primer of deep penetration
A universal primer is particularly useful for processing porous surfaces and can be used on a wide range of surfaces, including brick, metal, and wood. Because of the composition’s higher hitch, you can coat the surface with a wide range of materials without worrying about them spoiling.
Aquatic Penetration Aquastop
Deep penetration coatings of exceptional quality can be applied to porous surfaces like chipboard, slag block, foam concrete, and fiberboard. The manufacturer provides an average consumption range of 0 to 120g for a single coating layer with a primer.
The manufacturer provides information on the composition of the expenditure per square meter on the package, but you should be aware that this is only an average number and not an accurate indicator. Real consumption varies widely and is influenced by numerous factors.

Acrylic and facade soils
In addition to the powder form that is available for purchase, rich liquid acrylic primers are also an option that need to be combined with soda.
- Acrylic primer has white color, in connection with this it is not recommended to be used on dark surfaces.
- It is used to base before covering the wall with wallpaper, drywall and before putty. The average consumption of the composition may vary from 120 to 150 g.
- Acrylic primer can be used for the base for painting walls with acrylic paint, also for decorating the walls of the facade of the building before putty or other type of finish.
Acrylic primer
The acrylic composition will typically require 150 g for primed walls. About 100g of water-dispersing facade primer will be needed for painting.
| Primer Type | Consumption per 1 m² |
| Acrylic Primer | 0.1-0.2 liters |
| Epoxy Primer | 0.15-0.25 liters |
| Polyurethane Primer | 0.2-0.3 liters |
| Oil-based Primer | 0.1-0.2 liters |
| Shellac Primer | 0.1-0.2 liters |
| Latex Primer | 0.1-0.2 liters |
Comprehending the precise computation of primer consumption per square meter is imperative to guarantee a seamless and effective painting procedure. Understanding the particular requirements of your project will help you make the appropriate primer purchases, preventing both excess and shortages. This contributes to a more ecologically friendly strategy by saving you money and minimizing waste.
The kind of surface you are working on must be understood in order to calculate the appropriate primer dosage. Different materials, like metal, wood, or drywall, absorb primer in different ways. The recommended coverage for each type of primer is typically listed on the product packaging. To obtain an accurate estimate, it is important to refer to these guidelines.
Measuring the area to be covered and then applying the primer’s coverage rate are the first steps in determining the required amount of primer. For example, if a liter of primer covers ten square meters, and your area is fifty square meters, you would need five liters of primer. Always think about doing at least two coats, particularly when working with porous materials or on highly absorbent surfaces.
In actuality, it’s better to slightly overestimate to take uneven surfaces or any unforeseen absorption into account. Having extra primer on hand for touch-ups or future maintenance is also a good idea. With a little bit of preparation and calculation, you can get a professional finish with the least amount of work.
For painting projects, figuring out the right amount of primer is essential to preventing waste and guaranteeing a smooth finish. The type of surface, the primer’s coverage rate, and the number of coats needed should all be taken into account when calculating how much primer you’ll need per square meter. Primers typically come with a coverage rate listed on the packaging, which typically ranges from 8 to 12 square meters per liter. You can calculate the required quantity with accuracy by multiplying the surface area by the number of coats and dividing by the coverage rate of the primer. To help you become proficient with these calculations and make sure you purchase the precise quantity of primer for your project, this guide offers step-by-step examples.
