If we consider the composition of the gypsum solution, then it is based on plaster, as well as modifying and natural components. It is thanks to additional ingredients, it is possible to get a quality product that will serve for a long time.

Very often, people ask such a question: is it possible to get a gypsum composition at home? Sure you may. But to achieve universal qualitative characteristics In this case, it will not learn, because the factory is used innovative technologies. In addition, there is an accurate definition of proportions and a mixture is obtained, the consistency of which is optimally suitable for applying.

Gypsum plaster is a universal building material, thanks to which you can get a perfectly smooth surface and at the same time spend the minimum of effort and time. By purchasing this product, you need to carefully study its technological characteristics. It is important to buy a product that is ideal for your operating conditions.

In fact, the consumption of plaster plaster on 1M 2 is indicated on the packaging by the manufacturer, but there, as a rule, we are talking about a layer of 10 mm, which is never impossible in practice. However, it is possible to produce calculations, but for this we need certain data on the value of the treated surface of the surface.

Below we will talk about the most simple methods Calculations of the required amount of putty, how to save it, as well as let's see the thematic video in this article as a supplement.

Material consumption is better to know in advance

Note. For calculations of the spectal consumption, the draft base is of paramount importance, which will be shuffled.
Parameters as the amount of chosel and the depth of the plane drops are taken into account.

Miscellaneous Surface - Different Consumption


  • If you want to produce home repair with your own hands, I will definitely have a need for an independent calculation of the number of necessary for this building materials, among which there are plaster plaster. Such a putty is used exclusively for internal work and serves to level the ceilings, walls, as well as door and window slopes.
  • The smallest amount of the mixture goes to the processing of surfaces, where plasterboard sheets are served as a rough basis - the thickness of the layer there reaches only 1-1.5 mm. For GLCs, cement-sand light-colored plaster is followed - there is not so smooth surface, so you can add an extra millimeter to the thickness. Brick and stone walls, as well as concrete floors have docking seams and slots, which additionally leaves the solution, as well as drops along the plane.
  • Perhaps the greatest amount of solution on M 2 is required for slopes of windows and doors, especially after they are replaced during the repair of the room. When they dismantle the old construction, sometimes it happens that the huge pieces of old plaster fall out or even bricks. But even if the windows or doors were removed carefully - it's all the same when cleaning the surface of large differences is not to avoid.

Learning to consider

So, as we have already seen above, the rate of consumption of gypsum plaster is indicated on the packaging by the manufacturer and most often 8.5 kg / m 2 with a thickness of 10 mm.

As you understand, the uniform layer is possible except on the drywall, and only on one sheet, and then (along the edges), the recesses and joints begin there.

Let's see for clarity trying to calculate the amount that is necessary for the alignment of the brick wall is 2.6m high and 5 M width. Imagine that we will use for tightening a half-meter rule, therefore, the distance between the May profiles should be 10-15 cm less. In this case, we need 5 profiles for a five-meter wall located approximately 120 cm from each other.


Now we need to determine the average layer thickness indicators for each profile separately, and then we can get a total amount - this is necessary in order for our calculations to be more accurate. So, on each of the installed beacons we find two indicators for the remoteness of the profile profile from the draft base - one of them should be the biggest, and the other is the smallest throughout the entire length.

For example, the deepest point we will have 60 mm, and the smallest is 10 mm, it means (60 + 10) / 2 \u003d 35 mm - this is the average.

Now imagine that on other lighthouses, we have 2.5 cm, 3 cm, 4 cm and 5 cm, then (2.5 + 3 + 3.5 + 4 + 5) / 5 \u003d 3.6 cm or 36 mm / m 2. Now we need the overall area of \u200b\u200bthe whole wall and it will be 2.6 * 5 \u003d 13 m 2. But we lack another indicator, this is tolerance of the mixture of the mixture on the seams in brick masonry - Let's add 4 mm layer for this, then we will have 36 + 4 \u003d 40 mm / m 2.

Now we have the opportunity to learn the total number of putty, which we have to spend on this wall and after that, of course, the price of the material required for repair will be understood. If the thickness of the layer we have 40 mm, and by 10 mm for a square meter, 8.5 kg of spitels are needed, it means that in this case, 8.5 * 4 \u003d 34 kg / m 2 will be required. Considering the fact that the whole wall has 13 m 2, we will have to spend 13 * 34 \u003d 442 kg, that is, 15 thirty-tilogram bags of putty.

Of course, the cost of putty is a considerable and if the wall is very uneven, then you may have to find ways to save materials and there are. You understand that the cement-sand solution is much cheaper than plaster plaster, therefore, the aligning layer can make a mixture of sand and cement, as you see it in the photo above. After you, it remains to apply a layer of start-up (under the wallpaper) or the finish (under painting) of the plaster mixture, the thickness of which will be no more than 2-3 mm.

In addition, you can use drywall as a rough base, then saving funds on the plaster surface will be even more. It is very convenient to use GCC for alignment and mounting curly ceilings.

Council. If you need to apply a thin layer of putty, then its thickness can be adjusted by the slope of the spatula (mines).
So, the smaller the slope (the angle between the tool and the surface increases), the thinner you will have a plaster layer.

Conclusion

As you can see, calculate the total consumption of the material is not so difficult, especially since the instructions for use on the package determines the costs of square meter With a certain thickness. But when working and calculations, it should be borne in mind that a manufacturer determines the permissible thickness of the layer, which can be set in a mixture and neglect this should not be specified.

Repair is a good and necessary, requiring certain skills and knowledge. This case is never late to learn. And well thought out and the calculated repair is doubly good! It does not matter if you will repair or resort to the help of specialists, calculate the volume of the material and determine the cash costs will have to be independently.

So, you decided to start repairs from the walls of the walls by plaster. Subsequently, the 1st question arises - how to find out the consumption of plaster on 1m2 for compiled estimates? Let's first decide on which the material consumption depends.

Allocate 2 main factors affecting their number:

  1. Irregularity or curvature. Deviation vertically or horizontally plane itself and is curvature. The smaller this deviation, the smaller the material is required for alignment. The owners of old apartments will have to spend more material for finishing than residents of new homes, where deviation can range from 20 to 25 mm.
  2. Type of mixes itselfwhich will be used. From this indicator and will depend on the amount of consumption of materials.

So, the type of walls were determined, you can move to the next step.

Consumption of plaster per 1 m2 walls.

To calculate the consumption of plaster, you need to calculate the required layer thickness. For this:

  • We free the surface from dust, old wallpapers, former layers pcs.
  • Measure and exhibit lighthouses by level.
    (Lighthouse is a flat profile, with a V-shaped protrusion, which is a guide in holding plastering).
  • We note in several places of the point for which we will define the curvature. To make the result as accurate as possible, mark more points.
  • We measure the deviation from the plane, summarize and divide by the number of points marked.

An example of calculating the thickness of the layer:

You facilitate the task to align the wall with a size of 10 m2, in which the maximum curvature is 5 cm, that is, at different points there may be different values, and the maximum of rolled - 5 cm.

  1. We check the walls at three points in which the deviation is 1 cm, 3 cm and 5 cm.
  2. Values \u200b\u200bWe summarize: 1 cm + 3 cm + 5 cm \u003d 9 cm.

The number of points for the example was taken 3, therefore the amount 9 divide by 3, it turns out 3 cm. So it means to evenly align this wall, you must apply a layer of 3 cm.

Now it is necessary to calculate the flow of dry mixture per 1 m2 plaster. It is very simple to do this, even to the one who first encountered this task.

We take the basis of the example considered by us above. Typically, manufacturers on the package indicate the flow of dry mixture per 1 m2 for applying the pcs of 1 cm. Select an arbitrary mixture, for example KNAUF ROTBANT.

Dry mixture consumption.

8.5 kg (manufacturer's norm) * 3 cm (average curvature thickness) \u003d 25.5 kg.

Since we need to align 10 m2, we take our 10 m2. We multiply by 25.5 kg, it turns out 255 kg of a dry mixture for plastering the wall of 10 m2.

Also need to be considered required amount bags, because to buy or order you will be precisely bags, and not for the weight. The resulting amount (255 kg) is divided by 30 kg (manufacturer packing) \u003d 8.5. Round up to a whole bag in the most side, as in practice it turns out that the flow is obtained more than when counting, we obtain 9 bags.

Consumption of the main types of plaster and its characteristics.

Cement mortar

In its parameters, it is used mainly for roughing, is always applied with a thick layer. A thin cement coating quickly cracks, its minimum thickness must be 3 cm.

Therefore, the consumption of cement on 1 m2 of plaster will be approximately 16-18 kg.

Gypsum composition

consisting of small components, easier. The material is very universal, you can use both internal and outdoor work. Very plastic, quickly freezes, so it must be missed by small portions.

Consumption of plaster powders per 1 m2 walls, a layer of 10 mm - 9 kg.

Decorative

This is a common name for mixtures used for finishing indoor finishing or outside. Of course, they can align the ceiling or walls, but because of their high cost, it is better to use on purpose.

On average, the flow rate of decorative plaster on 1 m2 has 7-8 kg.

Varieties of decorative plaster:

  • Textual mixtures are used to imitate the texture of the stone. Tree, leather. Its consumption ranges from 0.8 to 1.5 kg per 1 m2. It all depends on the inclusions, the grains in the structure itself than they are smaller, the less consumption.


  • Structural plaster. It is manufactured on the basis of acrylic resins, cement or gypsum. Its feature is that after drying, a relief pattern is formed on the surface.


  • Plaster Coroede. This type of plaster won a special popularity with its uniqueness. The consumption of this material is on average from 2.4 to 4 kg per m2. This difference is due to grains different size and the thick layer's thickness. To find out the exact consumption, you need to read the recommendation from the manufacturer. If, for example, to compare the cores of the volatile and the cores of the prospectors, the difference in the recommended amount will be different. The average recommended size is -2.5 - 3 kg / m2.


  • Venetian plaster. This material is very popular among finishing materials. Mimics natural marble, with the same glitter and overflows. This is achieved by applying layers of plaster on the surface perfectly aligned. On 1 m2 walls you need only 200 grams of this plaster.


The correctly calculated amount of material will help you to plan the budget of your future repair, protect you from the need to buy material during the finish, exclude deception by workers. Do not be afraid to start something! Consider read, find out and everything will be sure!

When performing plaster walls, it is very often used cement-sand mixture. It should be prepared correctly - only in this case the surface will be solid and resistant to the effects of negative factors. One of the most basic tasks is to correctly determine the cement consumption per 1 m2 plaster. This can be done with fairly simple calculations.

Immediately note that there are several types of mixtures depending on the mass fraction of the hardener:

Consumption of cement on the plaster walls will depend on the selected type of mixture. Most often normal solutions are used, so the calculations will look at their example.


Types of mixes

Depending on the purpose of using the solution, it can be prepared in different percentage ratio of the components. In total, it is used in practice 3 options.

When the proportion is known, you can proceed to the definition of exact numbers that will be useful in operation. For this, a fairly simple formula is used. Calculations are carried out in several stages.

How to find the right numbers


In order to determine the cement consumption during the plaster on 1 m2, it is initially necessary to understand how the volume of the mixture is spent. Here everything will depend on the thickness of the layer, which can vary in different borders on separately taken areas of the base. If the surface is uneven, it is required to make measurements in several places and determine the average thickness of the layer. For example, if the average indicator is 2 cm or 0.02 m, then it is necessary to read as follows:

  1. we multiply the thickness of the layer on the area (1m2) and we obtain the volume of the necessary solution - it will be 0.02 m3;
  2. we translate into liters and get 20 liters;
  3. we determine the share of cement - it will be 0.005 m3;
  4. the mass part of the sand will be 0.015 m3.
Solution Structure The ratio of components for layer
spray soil apparent
Lime Lime Dough: Sand 1: (2,5 — 4) 1: (2 — 3) 1: (1 -2)
Cement Cement: Sand 1: (2,5 — 4) 1: (2 — 3) 1: (1 -1,5)
Clay Clay: Sand 1: (3 — 5) 1: (3 — 5) 1: (3 — 5)
Cement-limestone Cement: Lime Dough: Sand 1: (0,3 -0,5) : (3 — 5) 1: (0,7 -1) : (2,5 — 4,5) 1: (1 -1,5) : (1,5 — 2)
Lime-gypsum Lime Dough: Gypsum: Sand 1: (0,3 -1) : (2 — 3) 1: (0,5 -1,5) : (1,5 — 2) 1: (1 -1,5) : 0
Lime-clay Lime Dough: Clay: Sand 0,2: 1: (3 — 5) 0,2: 1: (3 — 5) 0,2: 1: (3 — 5)
Cement-clay Cement: Clay: Sand 1: 4: 12 1: 4: 12 1: 4: 12

Now it is easy to understand how much you need a hardener for the preparation of a solution designed to shock the square of the wall. Consumption of cement on plaster will depend on its brand. For example, if the M300 material is used, then one cubic meter There are 1100 kg. Accordingly, for the above formula, we need 5.5 kg of dry material. The higher the brand, the greater the mass, will increase and the calculated share.

If we consider and define accurate values \u200b\u200bof the cement consumption on 1m2 plaster you are not possible, you can purchase a ready-made mixture to perform upcoming work. On the package, the manufacturer indicates which volume of the composition is needed to cover the base and obtaining a layer with a thickness of 1 cm. You will also remain multiplied by the existing figure to the thickness obtained as a result of measurements, output the total material that is required for plastering the base.

Calculator for accurate calculations

There is another way that will help calculate the cement consumption on 1m2 plaster walls. This is a special calculator. You can find it on the site of one of construction companies either on any other specialized resource. You can use the capabilities of the program completely free. You only need to specify the available parameters to see the ready-made answer in a few seconds.


Usually in empty fields prescribe:

  • type of plaster mix;
  • length and height of the walls;
  • the thickness of the layer.

Important! A small error should be taken into account, which will arise due to the difference in the mass of the mass and volume of sand and cement.


There are more detailed calculators, where you additionally need to prescribe a brand of the hardener used, the type of sand, as well as choose the work option - external or internal. Finding such programs is more difficult, but still do it real.

Many to avoid problems with calculations simply measure the amount of material with certain tanks. For example, a bucket. The bucket of the binder accounts for three of the same sand tanks. It is easier and faster. But here may arise errors because of the cement brand.

Due to the fact that the plaster performs two functions - decorative and leveling, calculation of the number of components, including cement, must be made separately in each case. Specialists recommend "post-post" calculation on the so-called "middle thickness of the plastering layer".

Technology for determining the "middle thickness of the plastering layer"

In the entire area of \u200b\u200bthe plastering wall, the so-called "key points" or "lighthouses" are attached, which are exhibited by level. It can be nails, selflessness, screws or special planks. There is a rule here - "the more lighthouses, the more accurate the calculation." In general, "key points" should be at least three placed all over the wall area.

Linear measurements of the depths of the recesses are made, which in one place wall can be 5 cm, in another 2 cm, and in the third 6 cm. Measures of irregularities are summed up, after which they calculate their average value.

An example of calculating the "middle thickness of the plastering layer"

Suppose you have strengthened on the wall of 15 lighthouses and "put them in terms of or plundering. Next, the values \u200b\u200bof irregularities were measured and summed up - they received a number 67 cm. Everything can be determined by the "middle thickness of the plaster layer": 67: 15 \u003d 4.46 cm or 0.0446 m.

Example Calculation of the consumption of plastering solution per 1 m2 walls

In order to find out how much cement will go to 1 m2 plaster, it is necessary to first calculate the consumption of the plastering solution per 1 m2. Calculation of the average thickness: 1mx1mx0.0446m \u003d 0.0446 m3 Thus, for plastering 1 m2, the wall will require 0.0446 m3 of the finished solution.

Example Calculation of cement consumption by 1 m2 plastering wall

As is known, the standard plaster mortar includes "cement (M400 or M500), sand and water. At the same time, for the cement M400, the proportion of binder and sand for the kneading mortar is 1: 4, and for cement M500 - 1: 5. Based on the above proportions and averaged density of cement 1300 kg / m3, it is possible to calculate the number of cement.

For cement brand M400

  • 0.0446: 4 \u003d 0.01115 m3 (cement volume by 1 m2). For the convenience of further calculations, we give m3 to kg;
  • 1: 1300 \u003d 0.000769 m3 (volume occupied by 1 kilogram of cement);
  • 0,01115: 0.000769 \u003d 14.5 kg (number of kilograms of cement M400 required for plastering 1 m2 wall).

For cement brand M500

  • 0.0446: 5 \u003d 0.00892 m3;
  • 0.00892: 0.000769 \u003d 11.6 kg (number of kilograms of cement M500 required for plastering 1 m2 wall).
