How to calculate the consumption of plaster on m2?

Planning any building or facade renovation project requires knowing how much plaster will be required in a given area. It guarantees that you buy the appropriate quantity of materials, preventing shortages and waste. This is a simple guide explaining how much plaster is used per square meter (m²).

Measure the entire surface area that you want to plaster before you start. This entails figuring out the height and length of every section of the wall or facade. To find the area in square meters, multiply these measurements by (m^). The area of a wall, for instance, would be 5 * 3 = 15 m² if it were 5 meters long and 3 meters high.

Next, decide how thick you want the plaster layer to be. Plaster typically has a thickness of 10 to 20 millimeters, depending on the desired finish and state of the surface. This thickness can be converted to meters by dividing the millimeter value by 1000. 15 millimeters, for example, equals 0.015 meters.

Next, figure out how much plaster is needed per square meter. Multiply the surface area (measured in m2) by the plaster layer thickness (measured in meters). Using the 15 m³ and 0.015 m thickness from our previous example, we get: 15 m² * 0.015 m = 0.225 cubic meters (m³).

Finally, it’s a good idea to factor in a margin of error, taking into account realistic considerations like waste and variations in application. Generally, to account for these factors, increase your calculated plaster volume by approximately 10–20%. This guarantees that you will not run out of plaster during the project.

By following these steps, you can determine how much plaster you’ll need for your project with accuracy, which will help you stay within your budget and expedite the process of building or renovating a facade.

For builders and homeowners, we provide a step-by-step guide on "How to Calculate Plaster Consumption per Square Meter." Planning and budgeting require an understanding of how much plaster is required for a particular area of the facade of your home. We outline the variables that affect plaster consumption and offer helpful advice on how to calculate the precise amount needed, so your project runs smoothly and stays within your budget.

What factors affect the consumption of a plaster mixture

The plaster type to be used and the curvature of the walls are mainly determined by the plastering mixture consumption. The curvature indicator will be the main factor influencing the amount of material used to level the walls. The curvature indicator for a new building can be as high as 2–2.5 cm.

Manufacturers typically list the amount of mixture used per square meter, but the table below shows an approximation of the cost based on the material.

Secondary factors exist as well, such as the master’s experience or the way the composition is applied. Plaster is applied more economically by machine than by hand.

The specific type of coating that will be applied to the plaster is also crucial. Therefore, if a reinforced mesh is not used, it is not advised to apply a 2 cm thicker coating on a brick.

Brick

Because plaster must be applied correctly, brick is a popular coating.

Spray painting is one of the simplest methods for applying plaster. After dipping the brush into the plaster, it strikes the stick. There is still plaster spray on the facade. Applying the spray over two to three layers of soil followed by a thin layer of cover yields the best results. The following formula is suggested for the plastering facade’s thickness when applied to brick:

• spray 4-5 mm;
• soil (several layers) 5-7 mm;
• Cover 2 mm.

Concrete

The use of a reinforced mesh is also necessary when applying plaster to concrete. The maximum allowable layer is 20-25mm.

Making notches on concrete prior to placing it is highly recommended as it will improve adhesion.

The work differs from brick in that spray needs to be leveled. The primary layer of plaster is thrown onto the concrete; the process begins at the bottom of the wall and works its way around the corner.

Determining the facade’s thickness:

• spray 5 mm;
• The main layer is 10-15 mm;
• Cover 2 mm.

Aerated concrete

Because aerated concrete is a more "capricious" coating, it needs to be primed two or three times before plaster is applied. This will lessen the possibility of a fungus and improve the adherence of plaster and aerated concrete.

For the inside of the wall, the average layer thickness should be 4–8 mm, and for the facade, it should be 7-9 mm. Applying plaster involves throwing it from below up.

Tree

Applying a tree to another tree in the same manner as concrete. One layer of primer is applied first, followed by the top layer. Starting at the top and working down, the wooden surface is plastered.

If two layers of sores are filled in the wall, the plaster will be more likely to remain on the wooden surface. It is necessary to cross the stripes. The fights’ ends are fastened with nails.

The facade’s thickness will be:

• spray 10-15 mm;
• soil 5-7 mm;
• Patch 2 mm.

It is best to give the wall one more wipe after it has dried.

Calculation of facade plaster consumption for 1m2

Manufacturers frequently calculate for mm or cm coating and indicate a square meter on the package. You can either manually count or use a specialized calculator to determine how much of the required material is needed.

There are several types of plaster used for external work; the type used will depend on its composition. These kinds are frequently employed:

• gypsum;
• cement;
• acrylic;
• mineral;
• Silicone.

Furthermore, the majority of construction projects employ the first two kinds. For covering, ornamental plasters are utilized.

First, the wall’s level is examined, and three points with deviations are identified in order to approximate the plaster layer. When more points are ascertained, the outcomes will be more precise. Subsequently, the values are tallied and split according to the total points awarded. This will yield an approximately level plaster layer that needs to be applied.

Subsequently, you can perform the last calculations: multiply the area of the wall that needs plastered by the layer’s thickness and the cost specified by the manufacturer. The amount that emerges will be the total amount of material that is required. All that’s left to do is buy a measured amount and begin fixing.

When building a new home or remodeling an existing one, planning and budgeting require an understanding of plaster consumption per square meter. It makes sure you buy the proper quantity of materials without wasting too much or running out.

Measure the surface area that needs to be plastered first in order to get an accurate estimate of plaster consumption. This entails figuring out how many square meters each wall and ceiling total that need to be plastered. Keep in mind that openings such as doors and windows lessen the overall surface area that requires plastering.

Next, think about the kind and consistency of plaster you want to apply. The amount of coverage that one plaster can provide per millimeter of thickness varies. Although they use more material, thicker applications can offer superior durability and insulation.

Once you have these measurements, refer to the plaster manufacturer’s product specifications. They frequently provide the coverage in square meters or kilograms depending on the thickness of the application. This information aids in more precise estimation of the required plaster quantity.

Plaster consumption is also influenced by elements like application technique and surface preparation. A smoother finish can be achieved and material waste can be reduced with a well-prepared surface and effective application.

In conclusion, you can more effectively manage the budget and resources for your project by carefully calculating the plaster consumption per square meter and taking these factors into account. It guarantees that you buy the appropriate quantity of plaster, stay away from needless expenses, and get a good outcome for the facade of your house.
