It’s critical to know how much paint you’ll need when painting a room. You can save time, money, and effort by estimating the appropriate quantity of water-based paint per square meter. Purchasing excessively results in resource waste. You may need to make a last-minute trip to the store if you don’t buy enough supplies for your project.
Paints with a water base are widely used because they are simple to apply and dry quickly. However, a number of variables, including the color of the paint, the texture of your walls, and the number of coats you intend to apply, will affect how much you need to know. The amount of paint that goes a liter depends on all these factors.
We’ll dissect the variables affecting paint consumption in this post. Regardless of the size of the area you’re painting, this information will assist you in determining how much water-based paint you’ll need for the job.
Type of Surface | Paint Consumption per 1 m² |
Plastered Surface | 200-250 ml |
Drywall | 180-220 ml |
Concrete Surface | 250-300 ml |
Wooden Surface | 150-200 ml |
Previously Painted Surface | 100-150 ml |

Different types of material and their consumption
Choose the kind of material that will be used before visiting a hardware store. After all, the composition has a major influence on the characteristics of water-based paint and how much of it is used.
To find out how much paint is needed to paint a wall or ceiling quickly, use a paint consumption calculator.
Emulsion based on acrylic resin
This variety is thought to be the most common right now. Acrylic resin is the primary ingredient, as the name implies. Additional additions of various additives are what give the composition its desired qualities.
The resultant coating performs admirably and is impervious to moisture and mechanical impact. As a result, it is an excellent method for handling the building’s facade.
The typical amount of acrylic emulsion used on a square meter is 180 to 250 g for the first layer and 150 g for the second. It is dependent upon the technology of use and the foundational material.
Silicone -based emulsion
Silicone is this paint’s primary ingredient. This variety is unique in that it produces a surface with outstanding vapor permeability.
You can use this type of paint on the floor because it prevents the growth of mold and fungus. This is also an excellent remedy for walls that have multiple cracks that are no larger than two millimeters. This type is a good choice for internal work, unlike the previous one.
For 1 m2, 300 grams of silicone emulsion will be needed for the first layer. Just 150 g for two layers with the same specifications.
Emulsions with the addition of silicates
There is liquid glass in the material. This explains why the surface is so resilient to different kinds of pressure.
However, the composition is not fond of high humidity, even with a long service life (tens of years). This restricts how widely it can be used.
You will need 400 g for the first layer and 300–350 g for the second layer per square meter of surface.
Mineral-based solution
Such a product’s ingredients include cement or slaked lime. This material has shown to be very useful for indoor projects with brick or concrete surfaces.
For the first and second layers, the typical usage rate of such water-based paint per square meter is 550 grams and 350 grams, respectively.
They also sell a polyvinyl acetate emulsion that contains PVA glue. This kind of composition is very sensitive to any signs of moisture. It will be almost as much for one square meter as a mixture based on minerals.
Be aware that paint spray cans are currently available. Their uniqueness lies in how difficult it is to predict how much they will eat—even after taking the manufacturer’s suggested guidelines into consideration. These compositions have a pronounced chemical odor as well.
For any painting project, knowing how much water-based paint is used per square meter is crucial to planning and budgeting. You can prevent waste, save money, and guarantee a smooth, even finish on your walls by estimating how much paint you’ll need. This article deconstructs the variables that affect paint consumption, like surface roughness and painting technique, so you can determine the precise amount of paint you’ll need for your project.
It’s important to calculate the precise amount of water-based paint required when organizing your painting project. By being aware of the consumption rate per square meter, you can prevent paint waste and runouts during the job. The amount of paint you use depends on a number of factors, including the quality of the paint, the number of coats, and surface texture.
Paint is usually needed less on smooth surfaces than on textured or rough ones. Furthermore, using more paint will inevitably result from applying more coats. Always consult the manufacturer’s instructions found on the paint can for the most precise estimate. They offer a suggested coverage rate that accounts for the particular paint composition.
Never forget that buying a little extra paint is preferable to running out. You can use this excess money for touch-ups at a later time. Accurately estimating your paint requirements will save you money and effort while guaranteeing a smooth wall finish.
