A building’s external paint job can significantly improve both its look and value. The quantity of paint you’ll need is an important factor to take into account before beginning your project. Planning and budgeting require an understanding of how much paint is used per square meter for facade plaster.
The type of plaster, the surface’s texture, and the application technique are some of the variables that affect paint consumption. For example, more paint will be needed on rough or highly absorbent surfaces than on smooth, non-porous ones. Furthermore, the coverage rates of various paint types, such as oil-based and water-based, may differ.
By accurately estimating your paint needs, you can make sure you buy enough paint to finish the job without having to make repeated trips to the store or run out of paint. Because color batches can differ slightly, this not only ensures a uniform finish but also saves time and money. The paint manufacturer’s guidelines, which usually indicate coverage per liter or gallon on the packaging, can be a good source for accurate estimates.
You can determine the exact amount of paint required for your facade plaster project by knowing these factors and paying attention to professional advice. This will enable you to complete the task on schedule, within budget, and with a polished appearance.
| Type of Paint | Consumption per 1 m² |
|---|---|
| Acrylic Paint | 0.3-0.4 liters |
| Silicone Paint | 0.2-0.3 liters |
| Silicate Paint | 0.15-0.2 liters |
| Mineral Paint | 0.25-0.35 liters |

Prior to figuring out how much 1 m2 of the chosen facade paint will cost, you should be aware that every material has unique qualities. The first consideration is application method: freshly plastered surfaces cannot be painted with silicone or acrylic paints. Silicate paint, for instance, can be applied for roughly seven days. Next, the computation for each type of paint will be done independently.
Acrylic
There is a good range of colors available in this facade paint, and it has good stability against pollution. It is important to consider that this type of material is not suitable for use on silicate plaster or lime. Between 110 and 135 g of acrylic paint will be used per square meter, roughly.
The distinction between inexpensive and costly acrylic paint is shown in the video.
Silicone
You can be certain that the material will permit the facade to breathe if silicone paint is chosen. It also possesses characteristics that make it resistant to pollution and water. Approximately 200g will be consumed for every 1 m².
Walls with an old paint layer cannot be painted.
Cement
The owners of such paint will always be surrounded by pollution. The material’s low cost is its only benefit, but that advantage seems questionable considering that painted walls in residential buildings eventually lose their color and that the material’s original appearance on the facade fades over time. The consumption per m² is expected to range between 500g and 700g.
Silicate, polyilicate
These hues are renowned for having excellent qualities (like Pufas production). They completely reject water, do not easily become contaminated, and are unaffected by weather. Facade paint will be consumed at a rate of between 140 and 150 grams per square meter.
Water -based
Among the benefits is a reasonable cost. Furthermore, water-based paint does not pass water, does not burn in the sun, and is resistant to low temperatures. Three hundred grams of the mixture will be used approximately per meter.
One layer of coating with such a material is insufficient; apply two layers to the painted surface.
Alkyd
It could be argued that this is the most versatile coating available for painting concrete, brick, and wood. Because of its superior qualities, it should be well-liked by customers. It is unaffected by weather after application and keeps its original appearance for an extended period of time. This kind of coating is very simple to maintain.
Applying one or two layers of such facade paint on a square meter will require between 130g and 170g per square meter. The number of layers in this instance will vary depending on the required level of color richness. One square meter will require roughly 200g if two layers are insufficient.
Oil
Additionally, a high-quality coating that is fairly universal. The only thing to remember is that multiple layers can be applied to achieve a rich color. The approximate cost, if this is the first application, will be 150g per square meter.

Planning any painting project requires knowing how much paint is required per square meter for facade plaster. Precise computations prevent waste and guarantee a continuous, efficient workflow. Depending on the type of paint, the plaster’s state, and the application technique, different amounts of paint may be needed.
Smoother surfaces usually require less paint than rough or textured surfaces because the latter have to cover a larger area because of their unevenness. The use of primers is also important. Because a well-applied primer creates a more uniform surface and improves paint adhesion, less topcoat paint is required.
On their paint cans, manufacturers typically offer coverage estimates that are stated in square meters per liter. Since real-world conditions frequently differ from ideal ones, it is imperative that you abide by these guidelines and think about conducting a small test area to determine actual consumption. Temperature and humidity levels can have an impact on drying times and coverage effectiveness.
You can guarantee a successful and economical painting job by considering these aspects and precisely estimating your paint requirements. In addition to improving the facade’s appearance, proper preparation and attention to detail will extend the paint job’s lifespan and offer long-lasting protection and visual appeal.
