Front plaster consumption per 1 m2
Facade plaster - a building material that is intended for the facade of the building. The product is used to align walls and finish the building. It is important to correctly calculate the consumption of facade plaster per 1 m2, so that the funds are enough until the end of the work and there is no need to arrange a break with the subsequent fitting of materials. Correct calculation also helps to save.

What affects the consumption of material?
Two factors affect the consumption of facade plaster:
- The condition of the building base. Consumption depends on irregularities and defects. The curvature of the walls is calculated using the building level.
- Surface material. The greater the porosity of the building base, the higher the consumption.
- Type of funds. Different types of plaster have their own standard consumption indicators.
To understand how much material is needed for leveling and decorating the walls, the craftsmen figure out how many layers are required.
How do materials affect layer thickness?
Building base materials differ from each other in properties and characteristics. Each type of surface requires a different number of layers, therefore, the consumption of plaster is not the same.
Concrete
This is a relatively flat look. Strong differences and defects rarely occur. For this reason, the thickness of the plaster layer is 2 mm. This is the minimum value. The material in this case is applied to the surface without prior reinforcement. If there are large distortions on the surface or defects are present, then the layer thickness increases. The maximum consumption of facade plaster is 7 mm. If the material is applied in such a layer, it is recommended to pre-reinforce it before processing it with a building foundation, otherwise the plaster will not stick to the surface and will fall off over time.
Aerated concrete
For aerated concrete building base (as in the photo below), the layer thickness is 2-5 mm. If you apply the material with a layer of more than 5 mm, then cracks will form on the surface or the product will peel off and the plaster will fall off together with the finish.
Wood
A wood base usually does not need to be leveled and plaster applied. Finishing is applied directly to the material. Plaster is used in rare cases. Before applying the product to the surface, a metal mesh is fixed. To do this, the surface is treated with plaster. On a crude composition, a metal mesh is fixed. The material is pressed into the putty, and excess composition is distributed on the surface. Next, another layer of the product is applied to the surface and leveled with a spatula. The total thickness of the material is a maximum of 5 mm. The more layers you make, the higher the finish price.
Brick
When laying bricks, the space between the material is filled with cement mortar. Over time, the tool wears out and large defects form. The surface of the brick itself becomes uneven. Because of this, it is necessary to correct defects using plaster, so the material consumption for this type of base will be the largest.
For a flat surface without defects, the material is applied with a thickness of 5 mm. This is the minimum layer size. The maximum value without reinforcing mesh is 2.5 cm. Such a layer is applied if there are defects and minor irregularities on the building base.For large differences, it is recommended to increase the layer thickness to 5 cm, but before applying to the surface, a reinforcing mesh is fixed.
Calculation Methods
The consumption of facade plaster is calculated per square meter of surface. Calculation rules:
- treat the construction base with a grinder, grater or sandpaper with large grains - P 60 or P 80;
- fix the beacons on the walls - this manipulation allows you to find out the degree of differences in the building base;
- identify places where there are more curvatures - there should be several such points;
- measure the size of the differences at all points, add these values and divide the resulting amount by the number of points.
The obtained value is the number of layers that need to be applied per square meter of a building foundation. Based on this information, the required amount of plaster is calculated. Each product is accompanied by instructions that are placed on the package. It indicates how much product is needed per square meter of surface with a layer thickness of 1 mm. Comparing the information, the material is calculated. Professional craftsmen recommend making a stock, since the consumption of plaster may change, depending on the consistency of the product.

When a do-it-yourself master craftsman does it without experience in construction or with minimal skills, he is advised to carefully calculate the consumption of all materials, including plaster. This will save on repairs and perform quality work.
