How to calculate the consumption of putty per 1 m2 of the wall?

Puttying is a fairly common type of finishing work in construction. This is one of the last stages of finishing, carried out immediately before gluing wallpaper or painting the walls. It is used in cases where it is necessary to level the surface of the wall, to get rid of roughness. To obtain the most even surface, it is necessary to take into account many factors, and the most important thing is to know the rate of material consumption.

In the process of carrying out work, the most important principle is gradualness. The essence of alignment is the complete filling and smoothing, first of large, and then of smaller defects.

To carry out the work competently, you should follow the rules:

• The air temperature in the room should remain within +10 - 30 degrees.
• Air humidity should not exceed 50%.

It is also important to properly prepare the solution following the manufacturer's instructions. The quality of the finished mixture is influenced by the purity of the container, the literacy of the mixing process, and the observance of proportions.

In order to calculate the consumption, it is necessary to determine the type of putty mass, since they all have individual characteristics. The type of putty, in turn, depends on the surface material and the degree of its damage, as well as on what needs to be done with the wall further: paint, wallpaper or tile.

The modern construction market is represented by a variety of putty mixtures. There are many different classifications, but the main one is the differentiation of the types of putty according to the degree of readiness for use. According to this parameter, the putty is divided into two types:

This type of putty mixture has a lot of advantages and is a fairly popular solution for finishing work. The price for it is much lower than for the finished putty, it is stored longer and is more convenient to transport. It is not difficult to prepare a dry powder for application, the consumption of the prepared material will be small. However, it is necessary to strictly observe the proportions when preparing the solution, and also knead a new solution every half hour, since the old one will dry out by that time.

Such a putty will cost the buyer a little more, but it will significantly save time when mixing. In addition, when working with a ready-made mixture, there is no need to try to guess the ideal proportions. The disadvantages of this type of mixture are that the consumption of the finished material increases, and the shelf life, on the contrary, becomes shorter.

The types of putty also differ in their interaction with the type of surface to be treated.

In addition to the main varieties, which will be discussed below, mixtures are divided into the following groups:

• Adhesive mixture used for painting work. It is flexible, dries quickly and can last for a very long time. However, it is not suitable for use in outdoor work, it is not resistant to moisture and mechanical damage.
• Latex putty suitable for all types of surfaces. The cost is higher than that of glue, but this is offset by better technical characteristics.Easy to apply, does not crumble under the influence of stress. The disadvantage is low resistance to temperature fluctuations.
• Putty Tex is in high demand due to the possibility of application to almost any surface, as well as a variety of color palette. Possesses high stability, only poorly tolerates sub-zero temperatures.

• Water-dispersion mixture - the most economical type, while having good performance characteristics. The disadvantage is the complexity of storage - it is advisable to do this in an airtight container.
• Facade type of putty used to decorate the outside of the house. This mixture is characterized by high resistance to temperature effects, insensitivity to moisture, low cost. Minus - after finishing, it may begin to crack.

The types of mixtures can also be distinguished from each other depending on the manufacturer. Despite the huge number of different brands, several quality products stand out that can definitely be used in the renovation process:

• Putty "Vetonit" Is a high-quality mixture for plastering walls before finishing. "Vetonit" is used only in dry rooms, for one square meter you will need a little less than one and a half kilograms of the mixture. If the material is laid in a layer 1 mm thick, when using a putty for wallpaper / painting, the consumption will be equal to one and a half kilograms per square meter. meter of surface.

• "Shitrok" - putty mixture, which is characterized by a fairly low flow rate. With a layer thickness of 1 mm, it is equal to 0.5 kg per 1 m2. It is a polymer putty, which can be divided into latex and acrylic solutions. Can be used for gypsum plasterboard walls, does not contain asbestos, sold ready-to-use.

How much putty is needed to complete the repair, what parameters affect its consumption - this is the main question that needs to be resolved before starting work. To avoid getting into an unpleasant situation, when, shortly before the end of the work, it turns out that there is not enough material, it is necessary to calculate the required amount in advance.

Factors affecting consumption:

• the condition of the walls (the degree of roughness, the presence of cracks) and the material from which they are made;
• type of putty (front, decorative, for interior work);
• putty application technology;
• the correct preparation of the mixture;
• the next stage of repair (painting, whitewashing or wallpapering).

But first of all, the type of putty affects the consumption of the putty. Depending on the type of work, the putty is divided into three basic groups:

It is this type that is characterized by the highest consumption. Such a putty is used at the first stage of work, it is used to level the surface, seal cracks and chips. Penetrates deep into the wall, applied on top of the plaster

The second type of putty is consumed in slightly smaller quantities than the starting one. It can serve as a transitional stage from start to finish, or replace both types at once, but only if it is necessary to eliminate very minor flaws.

The species with the lowest consumption. It is applied as the last step before finishing finishing and is used to give the wall maximum smoothness. The finishing mixture can also be used as a first coat if only minor surface defects are to be removed.

The correct calculation of the amount of material is an important step necessary before starting finishing work. If the putty is less than required, it will be necessary to prepare a new one, and then try to dock it with the previously applied mixture. If the amount of the mixture exceeds the norm, then it will remain unclaimed, since it will no longer be possible to use it.Any mistake in the calculations delays the finishing process, postpones the completion of the repair.

To calculate the exact amount of material that will be used in the process of repair work, the following should be done:

1. find out the exact area of ​​the room;
2. measure the height and the sum of the lengths of the walls;
3. calculate the thickness of the walls, taking into account all surface defects;
4. determine the thickness and number of putty layers (taking into account surface defects).

It is important to remember that the amount of mixture used also depends on other less important factors. It often happens that a fairly large amount of unclaimed material remains in the process of working on tools, the composition hardens earlier than it is used. It also happens the other way around: you have to redo some areas in the process, which will require an additional mixture. In general, the inevitable losses can reach up to 10% of the total amount of material, so it is worth considering this point when preparing the mixture. In addition, the consumption rates of the putty depend on the basis of the mixture used.

The basis can be:

• cement;
• plaster;
• glue.

Before starting work, you need to figure out how plaster differs from putty.

Both are used in decoration and serve for leveling, but there are important differences between them:

• Plaster, unlike putty, is used in much larger volumes. With the help of putty, as a rule, only small defects are masked, while plaster evens out damaged areas of a larger scale.
• The price of putty is significantly higher than the price of plaster due to differences in composition.

To calculate the required amount of putty for a plastered surface, it is necessary to take into account climatic indicators and carry out work only in the range specified by the manufacturer.

Taking into account all the recommendations given by the manufacturer, per sq. m of area usually requires one and a half kilograms of putty. However, the thickness of the applied layer and the quality of the wall, as well as the area of ​​the filling, should be taken into account.

For walls without significant defects, it is enough to apply a layer of 1 mm (the calculation is equal to a kilogram per 1 m2) of the starting putty and 0.5 mm (0.6 kg / m2) of the finishing coat. Increasing the layer thickness results in a proportional increase in consumption. Do not forget about re-filling, which is better to be included in the calculation even before starting work. Consumption is approximately equal to one kilogram per square meter.

Currently, drywall is one of the most common options for decorating a room. There is an opinion that it is not necessary to putty the coating in the presence of drywall, because it already has a flat surface. However, this opinion is erroneous. You should definitely use a finishing putty to prevent the paint or glue from absorbing into the drywall.

The exact consumption is directly related to the surface area to be treated. There is a little trick that allows you to reduce the amount of the mixture: before filling, drywall sheets must be treated with a primer.

The amount of material for work depends on the composition.

The consumption table looks like this:

• When mixing cement-based putty, the calculation is 1.2 kg per square meter.
• A polymer-based mixture is consumed less than others - only 0.6 kg per 1 m2, but this type of composition is the most expensive.
• Gypsum mix is ​​the most economical option. Consumption is 1 kg per 1 m2.

Drywall is quite simple to work with. If the sheets were initially installed correctly, then careful alignment can be dispensed with. Before the finishing coat, it will be necessary to properly seal the fastening joints and the caps of the self-tapping screws.

When working on other types of surface, the walls should be covered with a layer of primer. In general, the amount of putty on concrete is only slightly at odds with the costs for the above types of surfaces.For a smooth concrete wall, the first layer is required not thicker than 5 mm, and the second - not exceeding 3 mm in thickness. Taking into account the thickness of the layer, the calculation of the consumption per square meter is made.

You can also putty on wooden surfaces. But the layer of the applied material should not exceed 2 mm.

When filling surfaces, the sequence of works and their technology should be carefully observed. When preparing the filler from a dry mix, carefully follow the instructions given by the manufacturer. Use only clean containers, mix thoroughly, add water strictly in the required quantities.

Incorrectly prepared mixture:

• Will increase the consumption of material, which means that it will raise the estimate for repairs;

• Will significantly reduce the quality of work.

It is important to remember the density of the mixture - in order to level out large defects, a thicker consistency of the putty will be needed, which will entail an increase in the consumption of the composition.

Compliance with simple rules eliminates the risk of poor-quality work performance.
