The calculation of paint for 1 m² can be done with some basic knowledge and motivation. Then you can independently calculate how much material is required to paint the facade on plaster, this will help save a decent amount of money.

It is very important that the coating protects the facade of the building from precipitation, extremely low temperatures, wind and scorching sun, as well as from the harmful effects of air and rainwater. Not only the appearance of a newly built or renovated house depends on the type of paint, its quality and tone. The characteristics of the coating determine the durability and how the house will look in 10 or even 20 years. Therefore, there is no frugality in buying a cheap paint and varnish material, paint consumption is not calculated at all in order to save money. It is better to afford to buy the best quality paint, in which case the facade will look new for a very long time.

By the type of approach to outdoor work, facade paints are divided into two groups.

1. First group- organic paints that are never applied to fresh plaster. This group includes silicone compounds, acrylic paints and silicone-acrylic coatings.
2. Second group- inorganic (mineral) paints, which can be used to cover fresh, still damp plaster after about a week. Inorganic formulations are less popular than organic formulations. These are silicate paints, lime and cement coatings.

When choosing the type of paint for the facade, two main factors must be taken into account: the color range and the degree of air pollution. This will allow you to find exactly the product that is ideal for a particular building and will give it an attractive appearance.

The choice of paint is often dictated by the type of plaster. When restoring buildings, the most commonly used are: lime, cement or cement-lime paints. In modern construction, as a rule, thin-layer plasters, silicone, acrylic-based compounds and silicate minerals are used, which are components of a well-thought-out insulation system for a house built using modern technologies. The easiest way when buying paint is to apply a simple principle - it must be of the same type as the plaster.

Acrylic paints

Acrylic paint has very good adhesion to the substrate, elasticity, resistance to dirt and rinsing with water. It boasts a low permeability, it is suitable for restoring an old facade, it can also be painted on mineral substrates, placed on previously painted layers of cement and cement-lime plaster. It should not be used on surfaces of silicate and lime plasters.

Acrylic paint consumption - 110-135 g / m².

Silicone paints

Silicone paints and varnishes are a vapor-permeable product that is resistant to sun radiation, which allows the facade to breathe. It protects the walls from water penetration from the outside, does not lend itself to chemical pollution, exhaust gas and acid rain. Silicone paints form a flexible and dirt-repellent film. They can be used on many surfaces, such as old paint-coated walls or the façades of historic buildings.

Paint consumption is about 200 g / m².

Silicone-based facade paints. Peculiarities

Cement paints

It is a mineral material that is sold as dry mixes. It is dissolved in water or in a liquid preparation, which is offered by the manufacturer. Cement paints are characterized by high vapor permeability and water absorption. They are easily contaminated and are therefore very rarely used in residential construction today.

There is a rule that the paint must be adapted to the type of plaster. Cement paint is used for painting cement-lime and cement plaster. And it is probably one of the cheapest. When it comes to color, she has limited choices.

Consumption - 500-700 g / m² (two-layer coating).

Polysilicate and silicate paints

Silicate paints are fairly resistant to moisture compared to lime paints, but have almost identical good vapor permeability. They are highly durable, resist the formation of mold and the harmful effects of atmospheric factors. Silicate paints are very resistant to dirt and the coating is not electrified. There is a fairly limited range of colors on sale.

Polysilicate paints are a modern innovative type of silicate paints, formed by enriching them with various resins. These paints are much easier to apply. They have excellent water resistance, high vapor permeability and, unlike their predecessors, are compatible with organic plaster.

Consumption of polysilicate paint - 140-150 g / m².

Self-calculation

As a rule, manufacturers place a calculator on their websites that allows you to calculate how much paint you need to buy. But the calculation can be done independently.

If the manufacturer indicates the consumption of paint on the packaging, then the exact consumption per 1 m² is very easy to calculate. For example, if the consumption is 10 m² / l, this means that 100 ml of paint will be required to paint 1 m² of the wall.

To calculate how many liters (or kilograms) of material should be purchased to paint the whole house, you need to decide on the number of layers that will be applied. As a rule, the surface of the walls is covered with two layers of paint. Much less often it happens that only one layer is applied. Sometimes painting is done with more coats. If the walls are covered with a primer, the manufacturer may suggest that the consumer be limited to one layer. When calculating for porous or rough surfaces, approximately 20% is added to the consumption indicated by the manufacturer on the packaging. Complex moldings and fittings will require additional paint.

Then, in order to avoid unpleasant surprises during work, the result obtained should be increased by another 10% -20%.

To calculate the surface area of ​​all walls, you need to measure the length of each wall, add all the lengths together, and multiply by the height of the house. But, of course, not everyone has a house that looks like a box of matches. In the figure, we can see that the red square has the same area as the blue triangle. This means that the surface area of ​​a triangular wall is not so difficult to calculate. Of course, you need to remember to measure doors, windows and other areas that are not painted in order to subtract the resulting area from the square footage of the task (this is about 10% of the total surface area of ​​the walls).

Additional factors affecting paint consumption

Manufacturer data

The vast majority of paints are offered by manufacturers in a ready-to-use form. Manufacturers write various data on the packages. In general, this information tells about the necessary precautions, about the benefits, purposes and conditions of use of the product. But a lot of this data affects material consumption. Ultimately, these descriptions will help you choose the most suitable product.

Regardless of the type of paint, the more binder, the higher the quality of the product.

Water absorption (absorption) coefficient

This factor should be as low as possible (about 0.05 kg / m²h0.5.). The lower it is, the more resistant the coating is to moisture, and the surface is less prone to contamination.

UV resistant

Excessive exposure to the sun's rays causes discoloration, cracks and swelling of the paintwork. The most resistant to UV radiation are polysilicate, acrylic and silicone-acrylic paints.

Vapor permeability

When a wall is designed so that each of its layers allows steam to pass through, this is considered a good property. Manufacturers usually indicate how many grams of water vapor penetrates the wall. The higher the indicator (more than 100 g / m²), the more breathable the paint is.

Abrasion resistant

It is given in wash cycles, dry or wet. The more cycles (approx. 5000) the better.

Drying time

The description on the label tells you when to apply another layer.

Attention! If the manufacturer gives two values ​​for paint consumption, it should be taken into account that a small indicator is used to explain how much paint goes to a flat surface, and a large one - to a surface with a pronounced texture.

Choice of tools

The paint can be applied by roller, brush and spray, the choice depends on the chemical composition of the coating and the surface to be decorated. It is worth adhering to all the manufacturer's recommendations as closely as possible.

Attention! The use of spraying can significantly reduce paint consumption, but it should be remembered that not all facade coatings are suitable for this method of applying them to the wall surface.

Smooth textured walls are easiest to paint with a brush or roller. The smoother the wall, the shorter the nap of the brush.

Attention! Paint consumption per 1 m² directly depends on compliance with the technology of work. When deciding to paint the walls yourself, you need to take into account that even the smallest nuances can affect the cost of paint and varnish material.

Facade painting instructions

The work must be carried out in good weather conditions specified by the manufacturer (on a sunny day, at an appropriate temperature, preferably in the range of 20-25 ° C, when there is no wind). Under these conditions, primers and paints form the most reliable protective dry film.

Step 1. Surface preparation

Prepare the surface before applying the paint. It is important to make sure that the surface of the wall is clean, free from dirt, peeling paint and cracks.

Prices for mixtures for leveling walls and ceilings

Mixes for leveling walls and ceilings

Step 2. Primer

It is necessary to use a special primer that matches the selected type of paint. The primer improves adhesion and absorbency, preventing the formation of stains caused by uneven paint absorption. Walls covered with a primer are easier to paint, this preliminary surface preparation will significantly reduce material consumption.

Step 3. Painting

If the primed wall is shiny, this means that it must first be painted with diluted paint in a 1: 1 ratio and only then applied at the concentration recommended by the manufacturer. The thicker the paint layer, the better the protection of the facade. Therefore, do not dilute all the finished paint - it is designed to provide the longest lasting protection. And, of course, you need to be careful when choosing a color. Some shades, such as deep blues and reds, will fade faster.

Today, most people choose painting for finishing the ceiling and walls. To purchase the required amount of any paint and varnish material, its consumption per 1 m2 is calculated. In this case, the structure of the material and the specifics of the surfaces to be painted should be taken into account. What are the consumption rates of PF-115 paint per 1 m2 and how to find out the exact indicator?

The abbreviation PF in the name of the enamel means PENTAFTAL. It is easy to decipher - the composition of the paint and varnish material includes alkyd resins and semi-dried oils, which allow the paint to dry quickly.

Where is PF 115 paint applied?

Enamel PF 115 occupies a leading position in the market of paints and varnishes. If you can describe it in one word, then the most appropriate would be "versatility". It is used for painting any kind of surface. The paint can be mixed with other compounds as well as with a primer.

With the help of PF 115, such types of work are carried out as:

• interior painting of premises;
• outdoor finishing work;
• painting on metal, plastic and wood.

The material perfectly tolerates high or low temperatures, atmospheric precipitation (rain, snow), and is resistant to UV rays. When enamel is applied to the surface, a dense, smooth film is formed. You can paint with brushes and rollers. In the presence of a spray gun, it is allowed to spray the composition over the surface.

On the video: types of paints.

Consumption rates per 1m2

All of the above characteristics have a positive effect on enamel consumption. But if the painting takes place in windy or sunny weather, the amount of paint used per m2 will double. Oil paint of light shades is applied in two layers, one will not be enough, as streaks and gaps will be visible. Therefore, choosing white, gray or yellow, enamel must be purchased with a margin.

If the paint needs to be applied in two layers, wait until the previous one dries, and only then get to work. It dries up to about 24 hours.

Prepare your wall or ceiling surface before painting. First, wipe it with a damp cloth to remove dirt and accumulated dust. In order to save paints and varnishes, level the walls with putty and treat with a primer. The primer increases the adhesion (adhesion) and service life of the material.

The surface should be smooth, free from flaws and cracks. It is from the correct preparation of the walls and ceiling that the consumption of PF paint per 1 m2 will depend.

As practice shows, the rate of consumption of the material varies from 100 to 180 g. Professionals also claim that, on average, one kilogram cans are enough to paint 15 m2 of the prepared surface. Also, the consumption of PF 115 directly depends on the selected color pigment.

Table of approximate consumption of PF-115 enamel (depending on the selected color)

Colour	What area is enough for 1 kg of paint	Paint consumption per 1m2, g
White	7-10 m2	100-140 g
Yellow	5-10 m2	100-180 g
Green	11-14 m2	70-90 g
Blue	12-17 m2	60–84 g
Brown	13-16 m2	63–76 g
Black	17-20 m2	50-60 g

You can reduce the amount of the coloring composition if you choose a silicone-based roller to apply it.

A spray gun is also suitable, thanks to a fine scattering jet, the enamel is applied evenly. Brushes absorb a lot of paint, which is why they increase the consumption of material several times.

When calculating the rates of enamel consumption, add to the total amount the percentage of loss from the location of the surface. If the floor is painted, the paint will not drip and drip, but for the walls and ceiling you will have to purchase material with a margin (about + 7%).

Do not forget that when painting a wooden surface, the paint will have to be applied in several layers, since wood, due to its uneven structure, absorbs a large amount of material. Consequently, paint consumption will increase. When covering metal surfaces, it is necessary to treat them from rust and dirt, and only then paint with the desired shade. In some cases, one layer is sufficient. Plastic is less whimsical.

If you buy more paint than you need, you can return it to the store within two weeks. To do this, the banks must not be printed, take a receipt for the goods and your passport with you.

Online calculator to help

There is another optimal way, thanks to which you can accurately determine the required amount of PF-115 paint. The consumption per m2, as well as the total amount of material required, is calculated using an online calculator. It will help you complete the necessary calculations in a matter of seconds. On our site you can use such a calculator.

In order for the calculation to be more accurate, you will have to indicate the necessary indicators in the table.

For painting walls:

• type of paint;
• the length of the room;
• the width of the room;
• the height of the walls;
• window area;
• door area;
• number of windows;
• Number of doors.

For painting floors:

• type of paint;
• the length of the room;
• the width of the room.

The calculator calculates the consumption for 1m2 and the total amount of the required material automatically.

If you are planning to paint the walls or ceiling in your apartment, do not write off inviting workers. To calculate the consumption of PF-115 enamel, use one of the above methods. Choose the shade of interest for the material in the hardware store or in the market. The staining process itself will not take much time, so you can do it yourself, thereby significantly saving your family budget.

Enamel PF-115 from different manufacturers (20 photos)

PF 115 consumption per 1 m2. Each paint has its own specific consumption and it depends on the specifics of the material itself and the surface that will be painted. I, like any master, are very interested in these values, because for high-quality preparation and for the purchase of the required amount of paint, you need to know all the nuances.

Consumption rates of paintwork materials

I must say that all norms depend directly on the factors under which oil paints are applied. And by the way, in different situations, these values ​​can be completely different. Let's immediately take a look at what are the consumption standards that are used by the majority, both generalists and inexperienced beginners.

On average, it takes about 110-130 grams of the dye mixture to apply one layer. Various factors that you will manipulate can both decrease and increase these indicators. To calculate the average consumption of oil paints per square meter, consider the following points:

1. What is the viscosity of paintwork materials
2. What is the condition of the surface for painting
3. With the help of what tools the material is applied - it can be brushes, rollers and a spray gun
4. What kind of work is being done, internal or external

The increase in the consumption of oil paints is due to the fact that there are losses associated with external factors. For a little comparison, I will tell you that when painting a surface inside a house for 1 m2, you can use more paint than when painting outside, if the weather is calm and dry. But if the weather outside changes dramatically, then the consumption of material may even double. Acrylic-based water-dispersion paints, oil paints and water-based paints have different costs. Today I will talk about the PF 115 oil mixture and the consumption rates of such paint per square meter.

Enamel waste rates

LKM PF 115 is used in both external and internal processes. This is, by definition, paint-enamel, which is mainly used for metal objects. If you read the description for the material, you will notice that it has a number of excellent properties:

• Not afraid of negative atmospheric influences
• Moisture resistant
• UV protected
• Not afraid of the wind

But there is a small nuance for these properties, the paint receives all excellent characteristics only after application and complete drying of the surface. But when applied, it is subject to all of the above influences and, of course, in order to avoid incidents, it should be protected as much as possible. Enamel for metal PF 115 will be consumed per m2 in greater quantities if the application will take place in windy and sunny weather.

The enamel consumption for metal depends on the color you choose, and therefore I decided to draw up a small and understandable plate:

If painting is carried out in bright sun, then be prepared for the fact that the consumption per 1m2 will greatly increase due to the evaporation of the enamel. I don't want to talk about specifics, as there are cases when the indicators literally double. Therefore, if you do not want to spend money on purchasing paint, then adjust to the weather. If you look at the table, then simply divide all the m2 data by two and get the area that will be painted in bad weather conditions.

Painted surfaces

Enamel PF 115 for metal, can be used for galvanized iron, as well as ferrous or non-ferrous metals. It is from the surface to be painted that what the consumption per m2 will be depends on. Typically, the rate ranges from 100 to 150 g / m2. When carrying out work, make sure that the surface is qualitatively prepared, it must be perfectly flat, since the enamel will show all the flaws.

In order to save a little paintwork, it is worth using primers for adhesion and putty to eliminate wall defects. Pay attention to the color of the metal that will be painted later. The consumption of PF 115 can depend on it, since the intensity of the original color depends on the number of layers applied.

Apply each layer with a roller or brush, and if you need to paint in 2 or more layers, you will have to wait for the previous one to dry. Usually one layer dries up in a day. By the way, if you paint with a brush, the consumption of the material automatically increases, since the tool literally absorbs the mixture. In the case of a roller, everything is much simpler, so think about purchasing this particular tool. But if, taking into account all the factors, the consumption of paint is still very large, then pay attention to the paintwork itself. Perhaps you are using a low-quality and cheap composition. Pay attention to the manufacturer, the instructions and the expiration date of the product.

Buy enamel in specialized stores, look at the quality certificate and never give preference to paints with a low cost. Usually, it is precisely such mixtures that lack the quality and properties necessary for the correct painting.

There are special consumption rates for PF 115 enamel, as well as for other types of paint applied to the surface.

But, in the process of working with the surface, various factors arise that affect the amount of material required for painting.

How not to get out of budget and calculate correctly consumption of enamel PF 115 per 1 m2, we will understand further in the article.

Application of PF 115

The main advantage enamel PF 115 in its versatility. Experts refer this substance to paint and varnish for use on all surfaces. That is why it has earned particular popularity in the building materials market.

It is allowed to combine the enamel with other coating agents, for example, with a primer. After application, the coating is not subject to spreading or smudging.

It forms a dense film with a smooth finish.

The name of the enamel begins with the abbreviation PF, which stands for pentaphthal or alkyd-based resins.

This kind used in work:

• outdoor type with finishing;
• for covering various types of surfaces: metal, wood or plastic;
• for work in the interior of the room.

This kind of enamel withstands high atmospheric loads such as snow, rain and the effects of low and high temperatures. That is why it is widely used both in home painting and in external work.

The application of enamel to the surface to be coated can be done using an ordinary brush, dipping or pouring. Spraying is also allowed in the presence of a special apparatus.

As part of the substance contains such components as:

1. Pentaphtali, which experts refer to as polymeric substances.
2. Resins, produced in various ways, including modified ones. They allow you to speed up the drying process of the surface.
3. Semi-dry and resins with special composite mixtures in a small amount.

Material consumption rates per 1 square meter

PF 115 is able to lie flat both in and in external surfaces. It is often used for work on metal.

If you carefully study the properties inherent in this particular enamel, you can find out that it has such advantages as:

Substance consumption in one layer per sq. a meter of surface varies from one hundred to one hundred and eighty grams.

It is noticed that when the product is coated in two layers and with a thickness of 30-40 microns, it will be about 90-130 grams per square meter.

A can with a weight equal to one kilogram can be consumed for seven or ten square meters. surface. From this calculation, you need to purchase material.

Factors affecting consumption

When buying a PF 115, it is important to remember that consumption per square meter is taken into account with the participation of several factors:

• feature of the viscosity of the product;
• the estimated number of layers to be applied to the surface;
• painting conditions, which mean the place where the enamel application process will be carried out;
• the color chosen to be applied to the product also affects the consumption. The least economical option is white enamel, and one of the lowest consumed colors is black.

All of the above characteristics really give the coated surface advantages, but it should be noted that they do not work if the enamel is not dry.

It is important to take care of the surface that has not completely completed the drying process.

If the master applies the application on a windy or hot day, then consumption of consumed material will increase significantly... This will happen due to the strongest evaporation of the enamel.

If the temperature reaches too high values, then the flow rate can be almost doubled. Therefore, it is important to choose a day for enamel with cloudy or cool weather.

Temperature, acceptable for carrying out such work, should be in the range from +5 to +35 degrees Celsius.

The use of either a regular brush in the work will imply the least consumption of funds. If the master uses airless spraying, this will significantly affect the amount of composition spent.

With pneumatic spraying paint consumption can be doubled.

For metal surfaces apply the ratio: a layer of soil mixture and enamel coating on top of it. Brick and concrete products must be coated at least three times for complete impregnation.

Calculation example

Suppose that one wall is eight meters long and the other is six meters, while the ceiling height in the room is two and a half meters.

When making calculations, it is important to indicate what type of surface is supposed to be coated. In our example, this is a plaster wall.

It turns out that consumption for walls is 7.8 liters... One square meter - 0.1 liter.

One of the most popular paints and varnishes on the market for construction materials is PF-115 enamel. The properties and technical characteristics of this composition have increased indicators, due to which the paint marked PF-115 (characteristics correspond to GOST 6465-76) differs from similar products in its resistance to abrasion and moisture. Also, this type of enamel is able to increase the operational life of the treated surface due to the high-quality mixtures introduced in the production. At the same time, the high level of quality of such products in general and the low price are perfectly combined, providing the product with demand and leading positions in the sale. For what exactly such a composition can be used, which means the abbreviation of the PF-115 marking, what can be the consumption of 1 kg of the mixture for 1 m2 of different surfaces and what is its composition according to GOST 6465-76 - we will tell about these and other main points in this article.

Basic terms and concepts

Before talking about the technical characteristics, the compliance of the composition with the GOST standards and about the consumption per 1 m2 of area, it is worth paying attention to the abbreviation. PF-115 enamel marking contains five elements, each of which is a carrier of a certain value:

· Name of the type of material - in this case, it is paint;

· PF means that the binder of the mixture is pentafle varnish (alkyd resin);

· 115 - digital designation indicates that the composition is three-component. The ratio of these elements conceals the development number, which is considered insignificant for the use of enamel at the household level.

The improved composition of PF-115 enamel, corresponding to GOST 6465-76, is considered universal. Such paint will be relevant, both as an independent coating when processing various surfaces, and in combination with primers. Enamels marked PF-115 can be used for exterior and roof painting, and for interior decoration. The composition is intended for the treatment of surfaces of wooden surfaces and metal structures (the consumption of the composition per 1 m2 will differ).

From the point of view of chemistry, PF-115 paint is a suspension of solvents, fillers, pigments, desiccant and rutile titanium dioxide mixed in pentafle varnish.

Paint composition

Produced in large and small containers (barrels, cans), the price of which is set depending on the mass of enamel in it, PF-115 paint can be white, gray, blue. The composition and percentage of the components will depend on what shade of the mixture is set.

For each of the enamels, the approximate composition may be as follows:

· White paint - pentafle varnish 28%, titanium dioxide 62%, white spirit 10%;

· Gray - pentafle varnish 20%, titanium dioxide 75%, white spirit 4.5%, carbon black 0.5%;

· Blue - pentafle varnish 26%, titanium dioxide 60%, white spirit 4%, azure 4%, zinc white 6%.

This composition of PF-115 enamel complies with the standards of GOST 6465-76. Before the products are released for sale, these and other indicators, technical characteristics of the dye mixture are checked.

Paint properties

The composition of PF-115 enamel determines its technical characteristics. The practical properties of the mixture depend on them. According to GOST 6465-76 for alkyd enamel PF-115, the technical characteristics are as follows:

1. The viscosity of the mixture, measured by viscometers, varies within 60-120;

2. Water resistance;

3. Resistant to fading;

4. Resistance to other external factors (temperature drops, atmospheric influences, etc.);

5. Resistance to industrial compounds, oils, detergents;

6. Film gloss (from 50% and more);

7. High coverage rates;

8. Consumption for 1 m2 of area - from 0.1 kg to 0.18 kg;

9. Drying time - 24 hours (at an ambient temperature of about 20 º).

Taking into account the composition of PF-115 enamel, corresponding to GOST 6465-76, its technical characteristics are distinguished by fire hazard and toxicity. Therefore, when using a mixture with this marking for finishing work, it is worth remembering about safety measures.

Purpose and application

Pentafl enamels, including paint marked PF-115, are intended for finishing surfaces made of wood, metal, as well as concrete structures and bricks. It is suitable for both interior decoration and exterior treatment of structures and buildings.

Manufacturers of such paints and varnishes, the consumption of which per 1 m2 is determined by the type of material, offer a varied color palette of PF-115 enamels. About 20 shades of enamel coating are offered by GOST standards by number 6465-76. Also, paint PF-115 is produced according to the RAL catalog, which provide uniform standards for shades and in which each color is assigned its own number. It should be noted that the price for 1 kg of enamel from this catalog is higher than the cost of standard shades in accordance with GOST 6465-76.

The enamel coating under the PF-115 marking has been widely used due to the fact that its technical characteristics meet high quality standards. Alkyd enamel PF-115 is used, the consumption of which for 1m2 is determined taking into account the type of surface and color of the mixture, for interior decoration, when it is necessary to paint windows, doors or heating pipes. For the treatment of external surfaces, paint is used, if you want to paint the roof, the basement of the building, the facade.

How to work with paint correctly

Before starting to apply enamel to the surface, it is necessary to determine the consumption of the composition for 1 m2 of area. The consumption of paint is influenced not only by the type of material to be painted, but also by the color of the mixture, as well as the method of application.

So, for example, 1 kg of enamel of the standard color according to GOST 6465-76 is able to paint over:

· 7-10 m2 if it is white paint;

17-20 m2 - black paint;

11-14 m2 - blue / light blue;

13-16 m2 - brown;

5-10 m2 - red.

Weather conditions play an important role in the consumption of the composition when painting surfaces with PF-115 enamel. When calculating the approximate consumption of an alkyd coating for painting metal, it should be borne in mind that in warm, dry weather, painting a building outside will require less mixture for 1m2 than for interior decoration. At the same time, in unfavorable conditions for coloring (strong wind, rain) the consumption of the mixture will be higher.

For processing wooden, concrete surfaces, bricks or plaster, you will need to apply PF-115 alkyd enamel in two layers with an interval between painting procedures of 24 hours to dry the first layer. In this case, the approximate consumption will vary between 0.13-0.15 kg of paint for an area of ​​1 m2 for one layer of coating.

The method of applying the mixture also affects the amount of enamel used when painting. Depending on the color of the alkyd composition and the tool used during the finishing, the consumption will be approximately as follows:

· About 0.13kg / m2 - if painting is done with white enamel, roller or brush with a maximum permissible thickness of a two-layer coating of 40 microns;

· About 0.08kg / m2 - if the surface is painted with black paint with a roller or brush with a maximum permissible thickness of a two-layer coating of 30 microns;

· About 0.110kg / m2 - when green paint is applied with a roller or brush at a maximum permissible thickness of a two-layer coating of 36 microns.

You can buy enamel under the PF-115 marking, corresponding to GOST 6465-76, in small containers (cans with packaging 0.8 kg, 1 kg, 2.3 kg) or large (barrel, drum).

Anyone who performs painting work on their own should know and be able to do one square meter.

Therefore, in this article we will tell you in detail about the consumption of paint, the conditions that affect the consumption rate.
And so, since there are many varieties of paints, in this article we will analyze only three main types: water-dispersion, oil and water-based.

Consumption of oil paint per 1 square meter

Few people know, but one of the main components of oil paint is drying oil. In this paint linseed oil serves to be a binder. And at the moment when we apply oil paint to the painted surface, the process of the so-called drying oil polymerization takes place. As a rule, PF-115 pentaphthalic enamel is used.

After applying this enamel, a film is formed, which has several features. It has a homogeneous structure and has the ability to not delaminate. On a single-layer surface, the average consumption rate will be 110-130 g / m2.

With the help of 1 kg of enamel, based of course on the color of the paint, you can process the surface with an area of: black - 17-20 m2, white - 7-10 m2, green - 11-14 m2, blue (light blue) - 12-17 m2, yellow / red - 5-10 m2, brown - 13-16 m2
Enamel is diluted using white spirit, solvent, or using their mixtures, adhering to a 1: 1 ratio.

The surface to be painted is treated with paint using a roller or brush. The surface to be treated is painted in several layers. The painting time between coats is approximately one day.

Consumption of water-based acrylic paint

Water-based acrylic paint is considered one of the most common paints used for painting indoors, as well as for some facade work. A distinctive feature of this type of paints is the ability to tint with color pastes and a distinctive matte appearance. With the help of water-dispersed paints, you can form a large color palette that will not be afraid of burning out in the sun. The instructions for the use of this paint say that the consumption rate does not exceed 8m2. But in practice, a consumption of 1 liter per 6-7 m2 is obtained. This difference arises because paint manufacturers intend to apply paint to a smooth surface. Moreover, the consumption of paint is affected not only by the surface roughness, but also by the absorbency.
The application method plays an important role in painting with this paint.

When applied using a spray gun, paint consumption will be less than using a roller when painting. But if there is no spray gun, then the choice is better made towards the roller than the brush. But, nevertheless, you need to take into account that the paint consumption will be 5-15% more than what is written on the bank.

To paint the surface with acrylic-based paint, you need to clean the surface and apply the paint in several layers. It should be noted that the better the composition of the paint, the fewer layers of applied paint will be needed. If the composition is of high quality, then two layers are made, if the paint is of lower quality, then three layers are applied. In other words, if you decide to save on paint, you end up overpaying.

I would like to note that when painting concrete, the color of the paint will remain unchanged for five years. But after two or three years, paint peeling may begin. When painting cement, plaster or other surfaces to be painted, remember that this paint can also be used for priming, after diluting the paint with water up to 10%.

Consumption of water-based paint per square meter

To calculate the consumption rates of this type of paints, the main attention should be paid to the consumption based on the consumption specified by the manufacturer per one square meter. On average, this consumption is one liter per 7-11 m2. But there are also such types of paints on sale in which one liter is consumed per 14-18 m2 of the painted surface in one layer. But sometimes the possible cases when the paint consumption given by the manufacturer will be very different from the actual consumption. Here you need to pay attention to a very important point and do not forget about the absorbency of the surface.

In order to reduce paint consumption and at the same time extend the service life, professionals recommend applying a hardening primer to the surface. Do not apply thick layers of water-based paint. As a rule, paint is applied in 2-3 layers. When applying the next one, it takes a break of 1.5-2 hours.

Repair work is impossible without the correct calculation of the consumption of materials. It is especially important to correctly calculate the amount of paint, which will significantly save not only financial resources, but also time.

Acrylic paints are some of the best on the market, but they cost a lot of money. If you buy too much of a substance, there will be excess, but the lack threatens not only to interrupt the work process, but also to break the identity of the shades on the painted surface.

What can affect paint consumption?

Often on paint cans they write how much volume is enough for a certain area. Only blindly using such numbers is not worth it, because all averaged calculations are based on the fact that the walls in the house are perfectly even. In real life, much more paint is needed than is stated in the instruction sheet on the container.

The main factors that affect paint consumption:

• method and methods of applying paint to walls or facades;
• what color was chosen;
• wall texture;
• what type of paint will be used.

Possible methods and means of application

A variety of tools are used to apply acrylic paint. Using a roller with a medium pile of flat relief, you can create a flat relief, and if you want to achieve the effect of a stone wall, it is better to use a short-haired roller... The specifics of rolling in both cases follows the same principle.

If we talk about a spray gun, the result of the work will depend on what kind of tool is chosen, what kind of mechanical pressure will be used during operation.

A wide brush is best used to scuff the wall. Use hard sponges or plastic trowels to blend.

Standard flow calculations

On average, if we are talking about acrylic paint (facade or for interior work), then one square meter takes from 170 to 210 grams. You also need to take into account the factor that for acrylic paint all calculations are made in grams, not milliliters.

It is important to know that average rates are only suitable for perfectly smooth surfaces.

• distance between floor and ceiling;
• the length of each of the walls of the room;
• multiply the length by the width.

Quite often premises are of a complex configuration, so it is important to take into account the complexity of the "relief". It is imperative that during the calculations, you should be guided by the plan-scheme.

You will learn more about paint consumption per 1m² in the following video.

Calculation of the amount of acrylic-type paint for wallpaper

Acrylic wallpaper paint has the following benefits:

• does not release toxins;
• has a good adhesion coefficient;
• dries quickly;
• is inexpensive;
• resistant to moisture and temperature.

If you need to apply acrylic paints for non-woven wallpaper, the standard consumption will be 210-260 grams per 1 m². In order to make painting as economical as possible, the main thing is to choose the right roller. If paint is applied in 2 layers, the costs will be, respectively, 400-450 grams one square meter.

Not only the material consumption, but also the layer structure will depend on which roller is purchased..

If we are talking about painting wallpaper with an absolutely flat surface, then to save money, a roller with a pile of at least five millimeters is chosen. More material is used to cover textured surfaces; for painting such surfaces, a roller is needed with a pile length of at least 25 mm.

Here you should know when to stop, because too long a pile will absorb a lot of substance, and it will be distributed unevenly.

We consider the consumption of dye for painting the facade

There are options when you can significantly save paint without compromising the quality of the coating. The consumption of the substance will depend on the tool that will have to be used, as well as on the material from which the facade is made and its texture.

At the standard rate, about two hundred grams of paints and varnishes are spent on painting the facade per one square meter of the coloring matter. If staining is performed on decorative plaster, paint consumption increases by at least fifty milliliters for each square meter.

When using textured acrylic paint, you should prepare 40 percent more of the coloring material.

Water-based paints are environmentally friendly materials, with which it is quite simple to work, for which you need to know all the features of their use. The consumption of water-based paint per 1 m2 of surface area is one of the important indicators that is necessary to calculate the amount required for work.

Water-based paint is the most convenient for painting walls and ceilings. it fits optimally on any surface, both outside the house and indoors. The surface on which it is applied can be any: concrete, brick, plastered walls, wallpaper. Paint consumption per 1 m2 depends on the type of surface to be painted and other parameters:

• If you use a primer for walls or solutions intended for strengthening before painting, then the paint will be absorbed less, and you can get by with one layer of paint.
• Before painting, the solution can be diluted with water, PVA glue.
• When painting textured plaster with protruding patterns, a little more consumable is required than for a smooth wall (by 10-20%).
• The hiding power indicator (the amount of emulsion that will be used to paint a dark surface) also affects its consumption. With a high value, it is optimal to apply two layers even with repeated full painting, with a lower value, you will need to overlay 3 or more layers.
• Typically, the second coat requires less paint.
• When using paint brushes, material consumption will also increase, but the sprayer is the ideal tool for working with skillful pressure regulation.
• Most often, rollers are used for painting, which are of several types: with a short-haired coat (for smooth surfaces) and a long-haired coat (used for painting rough walls), with foam rubber. The last 2 types require more finishing material.

Some rules for working with a roller when painting:

• The ink tray is sized so that the roller fits freely in it.
• The emulsion is poured in such an amount that its level is not higher than a fourth of the roller.
• When painting, the roller must be pressed against the wall with equal force to obtain an even coating.
• The roller should not be dipped into the emulsion too often, but rather try to paint with a thin and even layer.
• If the layer is too thick during painting, there will certainly be a large overconsumption of material, and besides, it will crack.
• Drying time for each layer is -1-2 hours.

Consumption rates

The manufacturer indicates the consumption rate on the packaging with the finishing material, but it is designed for the work of a professional and applying paint on a flat surface. The consumption of water-based paint per 1 m2 in many cases depends on its type and polymer composition.

Table of norms for the use of VD-paint per square meter

The consumption of a water-based emulsion also depends on the manufacturer, on air humidity and room temperature. The optimal microclimate for painting works is with warm and dry air at + 25- + 50˚С.

When finishing the facade of a building or other external work, the consumption of water-based paints per 1 m2 will be much higher, because the surface of the building is more humid and moisture evaporates faster. Therefore, the painted layer will dry unevenly, the number of additional layers of paint will increase.

Paint consumption when painting wallpaper is also high, because paper absorbs moisture quickly.

Painting various surfaces

Most often, water-based staining is done on a plastered wall or ceiling. The surface of the plaster can be smooth or textured (decorative). In the second case, more paint is always needed, because the bulges of the drawing will have to be painted carefully.

When painting colored plaster (with added powder dyes), the amount of water emulsion will be less if its tone is the same.

If it is supposed to be painted using a color (tinting), then it is necessary to buy a color scheme. In the store, as a rule, catalogs of companies are presented using a spectrum of colors. At the same time, the rates of consumption of the emulsion are also indicated, depending on the color of the color scheme.

The permissible amount of color for 1 liter of paint is 30 ml, i.e. 10 liters of emulsion will need 300 ml. The average consumption of color for VD-paint is equal to 20% of the total volume of the white composition.

In the video: the amount of color for water-based paint.

How to calculate

Before starting work, you should measure the painted surfaces in length and width, and calculate their area. For this, the perimeter of the room is measured. For example, one wall is 4 meters long and 3 meters wide. In this case, the perimeter will be: P = (3 * 2) + (4 * 2) = 14 meters. The height of the walls from floor to ceiling is also measured. If the height is 2.5 meters, then the area is calculated as follows: S = 2.5 * 14 = 35 square meters. Then the length is multiplied by the width. All calculations are performed in meters.

Then you should take into account those places where staining will not be done, and subtract them from the total. As a result, we get the area required for work, which should be multiplied by the flow rate indicated in the table by square meters.

To simplify calculations, you can use... To calculate, you need to enter the following information:

• area to be painted.
• paint type
• surface and number of layers

As a result, you will receive an approximate amount of material that you need and its cost (use calculators for an approximate calculation only !!)

There are special types of emulsions for painting the ceiling. Ceiling paint usually has increased wear resistance. Its consumption is calculated within 1 liter per 10 square meters, sometimes in reality it turns out less.

If you need to paint a concrete wall or untreated wood, then the material consumption will increase. When painting old whitewashed walls, the amount of emulsion used will directly depend on the level of surface contamination: the more dirt, the more layers you need to get a high-quality stain.

Dependence of paint consumption on the manufacturer

Any manufacturer aims to improve all the characteristics of finishing materials, enriching their composition with special additives. Therefore, the parameters of hiding power for different companies differ from the type of material.

For example, here are some of the norms for applying the paint layer from various companies:

And the last nuance: in order to save money, it is not at all necessary to buy cheap material. It is better to compare the emulsion consumption rates indicated by the manufacturers - in some cases it is more profitable to use an expensive paint that has a lower consumption rate.

When repairing an apartment or house on their own, homeowners are trying to save on consumables. It is better not to rely on the advice of consultants, but to be able to calculate the consumption of acrylic paints on your own. This is the only way to save money on the purchase of paints and varnishes, because any seller wants to sell as many goods as possible, and therefore can exaggerate the consumption of paint.

A correctly calculated amount of paint will avoid a shortage of material for work and the need to buy it in the future

To buy exactly the amount of paint and varnish material that you need for repairs, you will have to follow certain rules. In addition, a correctly calculated consumption will avoid a shortage of material for work and the need to buy additional paint in the future.

Normal consumption

Traditionally, the consumption rates of acrylic enamel are from 170 to 200 grams per 1 m2. It should be borne in mind that for acrylic the amount of material is measured in grams, and not in milliliters, as for water-based paint.

The standard only applies to work with smooth surfaces. That is, it can be a ceiling or walls covered with a finishing putty or an abrasive cloth with fine particles. When working on rough, uneven surfaces, the flow rate may be higher than usual.

Calculation of the amount of acrylic paint for wallpaper

If you want to paint non-woven wallpaper with an acrylic agent, then the average cost will be from 200 to 250 grams per 1 m2.

To be more economical, you first need to choose the right roller. Not only the consumption of funds, but also the texture depends on the correct choice of the roller.

For example, if you need to paint the smooth surface of the wallpaper, then it is better to take a roller with a short nap up to 5 mm long. For economical purposes, you should take a roller with a long pile (5-25 mm), which will help to achieve uniform staining.

For economical painting of wallpaper with acrylic paint, you need to choose the right roller

Acrylic consumption when painting the facade

For an economical and at the same time high-quality painting of the facade, you need to choose the right tool and pre-treat the surface. Depending on the texture of the facade, paint consumption can range from 180 to 200 grams per 1 m2. However, it may be more consumable and you will need 220-250 grams of material.

If you want to renovate using textured acrylic enamel, then the costs here can be much higher than usual. On the label, manufacturers indicate consumption rates that range from 1 kg to 1.2 kg per 1 m2.

However, for high-quality painting, one should not blindly rely on the numbers indicated on the bank, since they are calculated taking into account the work with an ideal surface. Therefore, ideally, it is better to purchase material with a certain margin of about 5% more than usual. This is necessary to compensate for the unusual texture.

For interior painting and priming, the acrylic compound for the first coat is best diluted with a water base up to 5%. The time between paint coats should not be less than 4 hours. To reduce consumption, experts recommend painting with an acrylic compound at a temperature of about +20 degrees against a background of normal humidity.

Using high-quality acrylic paint, you can do with two layers of application

Features of the consumption of water-dispersion paint based on acrylic

This type of paint is actively used not only for interior decoration, but also for facade work. Such a product is distinguished by a matte appearance and the presence of color pastes in the composition. The paint has a wide range of colors that does not fade under the influence of bright sunlight.

For water-based acrylic based paints, manufacturers usually indicate a consumption of about 1 liter per 8 m2 of surface.

However, in practice, the consumption is usually about 1 liter per 6-7 m2, that is, about 110 g per 1 m2. This is due to the fact that all rates are usually calculated for a thin layer under ideal conditions.

The method of applying paint also plays an important role. For example, the most economical way is to use a spray gun. However, even so, you need to calculate the amount 5% more than ideal.

In addition, it should be noted that acrylic compounds are always applied to a clean and dry surface in several layers. If you are using high-quality paint and varnish material, then you can get by with two layers. When using cheaper formulations, you will have to paint in 3 layers. So, it is better not to buy cheap paintwork, as it can end up being more expensive.

Conclusion

When applying acrylic paint, it is necessary to clearly know the consumption rates in order to correctly calculate the amount of paint and varnish material. At the same time, the amount of colorant required can be reduced by economical application and the use of the correct tool.
