Paint consumption per square meter. Paint consumption per square meter (1m2) White paint consumption per 1m2

Painting is usually done on square meter surfaces. When purchasing, be sure to pay attention to this indicator, usually written on the label. Knowing the amount of paint required to cover a square meter of surface, it is not difficult to make calculations regarding the required number of cans in a given case. This is convenient, first of all, in terms of saving money. After all, paint has its own expiration date. And the remaining banks may never be useful. Thus, for 1m2 this parameter is very important.

How to do the calculations

First of all, you need to measure the surface that will be processed along the perimeter and calculate the area. This will make it easy to determine exactly how many cans you need to purchase. At the moment, paint is most often sold in 3-liter containers. Thus, for example, to paint a floor with an area of ​​30 m2 at a specified consumption of 0.05 l/1 m2, you will need to purchase 2 cans. But this is only if the surface has previously been painted or well primed. Sometimes another parameter is indicated on the labels - how many meters one liter is enough for. In this case, calculating the number of cans will be even easier.

Dependence of consumption on the type of dye

Of course, painting a square meter of surface takes different quantities different types of helmets. Let us consider this issue in more detail, since when executing repair work it can be quite significant. Thus, water-dispersed acrylic paint is usually used to paint ceilings. For processing wooden and metal surfaces - various types of enamels. Facades are painted using special compounds that are resistant to water and temperature changes. They are considered very effective and easy to apply. So, what is the consumption of paint per 1 m2 when using one or another type of paint?

Acrylic water dispersion paint

Such dyes can be used both for walls and ceilings indoors, and for decorating facades. After application, they form a durable coating that perfectly hides all minor defects of the treated surface. You cannot use the same type of acrylic water-dispersion paint for both walls and ceilings.

The purpose of the composition must be indicated on the label. The fact is that the dye on the walls is subjected to much greater loads than on the ceiling. Consumption per 1m2 is usually 1/8-1/6 liter. That is, to paint 6-8 m2 you will need 1 liter of this product.

Tikkurila paint

Dyes of the Tikkurila brand are now well-deservedly popular. They form an unusually strong film on the treated surfaces that is resistant to abrasion and cracking.

Dyes are produced intended for painting plastered surfaces both in dry rooms (in this case compositions based on acrylic copolymer or latex are usually used) and outdoors. In the first case, paint consumption per 1 m2 (Tikkurila) is 0.1-1/ 8 l. That is, to paint 8-10 m2 you will need to purchase liter jar. When treating surfaces outdoors, a liter of product covers approximately 10-14 m2.

PF paint

Pentaphthalic enamel is another fairly popular dye today. It is used to treat surfaces both indoors and outdoors.

If it is applied to a previously unpainted surface, the consumption will be about 180-200 g. material per 1m2. This is very little. If a surface that has already been painted is treated, or a second layer is applied, the consumption of PF paint per 1 m2 will decrease by approximately 40 g.

When purchasing any dye, including pentaphthalic enamel, you should keep in mind that you usually need to apply at least two layers to obtain a high-quality finish. Therefore, when painting a new surface that has never been treated before, you will have to purchase a product at the rate of approximately 320-350 g. per 1m2.

Powder paint

Powder become in Lately increasingly popular. And no wonder. After all, with their help you can obtain a finish with properties that are completely impossible to achieve using conventional liquid formulations. Films created by such dyes can withstand truly colossal loads. So, what is the rate of paint consumption per 1 m2 when using a powder composition?

The calculation is made based, first of all, on the weight of the product and the thickness of the applied layer. The “lighter” the paint, the less it is needed to obtain a high-quality coating. The thickness of the protective and decorative layer should be at least 100 microns. As practice shows, when using a sprayer for painting, in this case approximately 120-140 grams are used per 1 m2 of surface. facilities.

Factors affecting paint consumption

Paint consumption per 1 m2 depends not only on its properties, but also on what surface it will be applied to. This factor often becomes decisive in the calculation. By indicating certain consumption rates on the label, the manufacturer usually means that the paint will be applied to a surface that is not too porous. In practice, it often happens that the wall being treated, for example, absorbs the product very strongly. As a result, it takes a little more. Usually in such cases it is necessary to paint the surface in several layers. This applies, for example, to materials such as wood and concrete. When painting metal and plastic surfaces Of course, less money will be spent.

Thus, paint consumption per 1 m2 depends, first of all, on the type of composition itself, as well as the type of surface being treated. In addition, this indicator is significantly influenced by which tools will be used during the work process. So, when painting with a brush or roller, paint is consumed somewhat more than when using a sprayer. Much in this regard depends on the skill of the person performing this work.

When choosing paint, you need to consider following parameters: hiding power, gloss level, density, thixotropy, solids, consumption, etc. For example, if you have to work on a smooth surface, then a glossy finish will be suitable, which will increase the reliability and durability of the coating. But if the surface has roughness, it is better to choose matte paint. The paint consumption is affected by its color: up to 10 square meters can be covered with white. m. surface (dark), and black - up to 20 sq.m.

Thixotropy is a measure of paint viscosity. The higher it is, the less smudges are formed during work. But thixotropy is not always indicated on the packaging. It is also important to pay attention to density. If it is high enough, it means there are a lot of solid particles in the composition, and the consumption of materials will be high. Paint having a small area allows you to save money by applying a thin layer to the surface.

Hiding power shows the ability to hide the natural color of the surface. There are several classes: 1 (requires painting in 1 layer), 2 (2 layers), etc. The banks indicate values ​​expressed in g/km. m., which indicate covering the area with dried film.

It is important to pay attention to the indicated paint consumption per 1m2 (the calculator will help you calculate the approximate amount). It is measured in kg/sq. m and additionally the number of layers that need to be applied to paint the base can be indicated. Consumption is sometimes indicated instead of coverage.

Simplified calculation method

Taking into account all the listed characteristics of paints, it is possible to determine the exact consumption of materials for finishing works. Best choice there will be a paint whose markings indicate all necessary properties. Material performance is usually ignored only if the paint is of very low cost. But then it’s worth thinking about quality.

Let's look at an example of calculating paint consumption. Let's take a room with an area of ​​30 square meters. m. (including openings). Let's say you've already chosen enamel, which is sold in 1-liter jars. You need to calculate how many containers will be needed so that there is enough for the finishing work of the room and there are no extra costs.

To do this, first of all we study the information on the packaging. Let's say the hiding power of this paint is 130 g/sq. m, dry residue – 65%. Taking these indicators into account, we will use the formula: (hiding power / dry residue) x 100 = consumption. It turns out: (130 / 65) x 100 = 200 g/sq.m. This amount of paint will be needed for 1 square. m. walls. We determine how much paint will be needed for the entire area: 200x30=6000 g (6 kg).

Now we pay attention to the density value: 1.4 g/cu. cm. To find out the volume, divide the mass by the density: 6/1.4 = 4.29 liters. This means that for the work you will need 5 cans of 1 liter of paint. If one coat is enough, you will still have about 0.5 liters of enamel left. An easier way to calculate is to use our paint calculator. Enter the necessary parameters and get the result in a matter of seconds.

What determines paint consumption and ways to save

Paint consumption depends on many factors: type, method of use, surface material and others. For example, if you need to paint a wall made of concrete or brick, you will need 15% more paint than for a metal or primed surface. It is also important to know that applying the second layer will take less paint than the first. So, if you need to paint rough coating, then pentaphthalic enamel will require about 200 ml per 1 sq. m., and the second coating will take 40 ml less.

One of the influencing factors is environment. Consumption will be different indoors and outdoors. For example, consumption water-dispersion paint inside – 150 g/sq.m. m. But for exterior finishing 200 g/sq.m. will be required. m.

Consumption will increase if a brush is used during work. To avoid this, it is recommended to apply the paint with a roller, or even better, use a sprayer if the type of enamel allows it.

During repairs and proposed paintwork, it is important to calculate the required amount of paint. Despite the information indicated on the packages, the amount of composition may depend not only on the type of enamel, but also on the type of surface. Therefore, in order to correctly determine the consumption of acrylic paint per 1 m2, you need to know the general principles of calculation and what types of surfaces and coatings there are.

Can be used for painting different surfaces accordingly. Various types paints For example, when painting ceilings, a water-dispersed acrylic composition is most often used. Wood and metal surfaces are treated with various enamels. For facades, special compounds are used that are resistant to water and temperature changes. Some of the most effective formulations for application are powder-type compositions.

Acrylic-based mixtures are widely used in repair work. Suitable for internal and external works and applied to different types surfaces. Such compositions have antibacterial properties and are suitable for wet cleaning.

Among the advantages it is also worth noting the following indicators:

• safety and non-toxicity;
• high quality material;
• long service life - 5-10 years;
• quick drying;
• at correct use significant savings are achieved.

Area calculation

If we talk about how to calculate paint consumption, first you should find out the surface area for paint in m². To do this, measure the perimeter of the room and the height of the walls from floor to ceiling. The length is then multiplied by the width. All calculations are performed in meters.

When determining the area of ​​the walls, it is important to take into account elements such as niches, projections, semi-columns, etc. The entire surface of the walls that will be painted is calculated, then the area of ​​the door and window openings is subtracted from it.

On each can, the manufacturer indicates the paint consumption per 1 m2 and the area of ​​the surface of the ceiling and walls that will cover 1 liter of material.

You can also use. To do this you need to enter the following information:

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

As a result of the calculations, you will receive an approximate amount of material that will be needed and its cost (use calculators only for approximate calculations!!)

Paint consumption rates

The established rule states that the consumption rate of acrylic paint per 1 m2 is 170-200 grams. Such standards apply when covering a smooth surface with acrylic. This can be a finishing putty or an abrasive cloth. If work is performed on an uneven, rough surface, paint consumption per square meter may be slightly higher.

On video: tips for choosing paint.

How to make a calculation?

Acrylic-based water-dispersion mixtures are widely used for interior and exterior decoration. Such paints give the surface a matte sheen, and you can create the desired tone using acrylic paste. Due to this, such compositions have a fairly large color scheme, do not fade or fade in the sun.

Aerosol acrylic mixtures should be applied to a surface for which primer, varnish and paint from the same manufacturer were previously used. Work can be carried out at temperatures up to +50°.

When choosing, you should pay attention to the recommendations on the packaging. If it is indicated that a liter of paint will be needed for 8 m2, no more, then in reality it will be enough for a maximum of 6-7 square meters. These indicators are influenced by factors such as surface texture, roughness and absorbency.

The method of application also influences how much material is needed. When using a spray gun, the paint consumption per m2 will be less than when painting with a roller. But when using a brush, you have to use 15% more material than indicated on the package.

It is better to apply acrylic mixtures in 2 layers, sometimes 3 are required, depending on the quality of the composition. With a high-quality solution, two layers will be enough.

When applying a coloring product to cement or plaster, the surface to be treated is additionally primed. It is worth remembering that for walls and ceilings you must use different types acrylic solutions. This is explained by the fact that the dye on the walls is subjected to much greater stress than on the ceiling.

Wallpaper paint consumption

When painting non-woven wallpaper, the average amount of paint per 1 square meter will be 200-250 g. For more economical application and to reduce the amount of paint consumed, you need to pay attention to the type of roller used. For example, when painting a smooth surface, the roller should have short pile, up to 5 mm. For uniform and economical painting of a textured surface, it is better to opt for a roller with long pile, 10-25 mm.

Consumption of acrylic composition during facade work

Based on the characteristics of the façade texture, paint consumption per 1 sq. can be 180-200 g per m2 of wall. Using decorative plaster this figure will rise to 220-250 g. For greater savings and high-quality painting, it is important to initially treat the surface and choose the appropriate tool.

The mixtures do not crack or fade. To preserve the beautiful appearance the surface needs to be updated once every few years.

Consumption of acrylic-based textured paints

When carrying out repair work using acrylic enamels, paint consumption per 1 m2 may slightly exceed the usual norm. The labels usually indicate a consumption of 1-1.2 kg per m2. However, to obtain a high-quality surface, you will need a reserve of material, approximately 5% more than usual. This difference compensates for the unusual texture.

For interior work and primers, acrylic mixtures for the first layer are recommended to be diluted with a water base to 5%.

Applying the second layer should begin no earlier than 4 hours later. In order to reduce the consumption of acrylic paint per 1 m2, craftsmen advise working at temperature conditions+ 20° and normal air humidity.

In fact, determining how much paint is used per square meter. hmm, pretty easy. It is important to take into account the characteristics of the paint composition and the characteristics of the surface being painted. Everyone should understand how correct calculation of paint consumption per 1 m2 of mixture will facilitate work and help save money. In many cases, the manufacturer provides information and recommendations for use that you need to build on. Then we calculate the necessary parameters and get to work.

Before purchasing paints and varnishes, it is wise to calculate the required volume. Many people believe that they can simply rely on these labels. However, the consumption rate may depend not only on the type of enamel and its hiding power - oil, water-based, acrylic or alkyd enamel - but also on the base material. Let's look at how to correctly calculate the volume.

First, let's talk about general principles calculations, and then we’ll go through the types of coatings and surfaces.

Determining the coverage area

Everyone remembers from school mathematics that to determine the area of ​​a surface, you need to multiply its length by its width. For example, the length of the wall is 5 m, the height is 3 m. We get a wall area of ​​15 sq.m.

Similar calculations need to be made for all rooms and surfaces that you are going to paint - walls, ceilings, floors. For paints different color and the calculation, of course, needs to be done separately. For example, you can add up the areas of all ceilings that will be painted in White color and separately the areas of the walls that will be painted beige.

When implementing design ideas (a combination of a painted surface with wallpaper, etc.), the calculations become more complicated, but the principle remains the same - we calculate the area of ​​only the surface that is to be painted.

Calculating paint consumption

Having received information about working area, look at the label. Branded products usually indicate hiding power and an indicator such as dry residue. Covering power is the ability of a material to cover the color of the base when applied uniformly in a single layer. Dry residue – those substances that will remain on the working surface after the enamel has dried. Usually it allows you to estimate the water and solvent content in the composition of paintwork materials ().

We calculate the approximate volume using the following formula:

(Having power/Dry residue)*100

If you need to paint a wall with an area of ​​15 sq.m., then with a material coverage of 120 g/m2 and a dry residue of 60%, the paint consumption per square meter will be equal to:

(120/60)*100 = 200 g/m2

We get the total consumption: 200*15= 3 kg.

It is also necessary to take into account the density of the composition. For example, the coating density is 1.4 g/cm 3 . To calculate paint consumption per square meter, divide the mass (3 kg) by the density (1.4 g/cm3) and get 2.1 liters. This means that you will need 2 cans of paint, 1 liter each.

Depending on type base surface and the properties of a particular coating, this figure can be +/-20%. For example, to paint a concrete, brick or plaster wall, you will need 10-15% more paint than for wood or metal surfaces. To reduce material consumption, walls can be pre-treated with a primer.

Consumption rates for oil paint per 1 m2

On average, painting a surface in one layer requires 110-130 g. coverage per 1 square meter.

However, the consumption oil paint on wood and metal, as well as other surfaces, may differ significantly. However, the differences can be significant even when in different ways application, and in different climates.

For example, during exterior work, oil paint consumption will be lower in dry weather (than during interior work) and higher in rain and strong wind. In the latter case, the consumption of oil paint per square meter can be twice as high as for interior work.

Second point. Since wood absorbs more metal, the consumption of oil paint on wood will be greater than on metal. The difference can be up to 2 times.

In addition, the required amount of coating depends on its color. Yes, dark

You will need more enamel (black, brown, blue, green) per 1 m2 than light enamel (white, yellow, blue). In this case, the consumption of oil paint per 1 m 2 for non-ferrous metal will be higher than for galvanized iron or ferrous metal.

Finally, the brush always picks up more material, regardless of whether its bristles are natural or artificial. When using a roller, the oil paint consumption is 1 m2 less. A silicone-based roller is ideal for painting metal surfaces.

Consumption rate of water-based paint per 1 m2

The average value per square meter is 140-160 g. This applies to one layer. With a high coverage rate, it is enough to apply 2 layers. Lower quality paints may require 3 or more coats. So before you buy cheap enamel, you should think about it - you will spend more of it, and the labor costs will be more significant. So is your savings worth it?

The façade consumption per 1 m2 is usually higher than when painting walls and ceilings indoors. Because the this type The coating contains water; on the outside, especially in the wind, it evaporates faster than on the inside, and as a result of uneven drying, additional layers have to be applied.

The consumption of water-based paint for wallpaper will also be higher, since the paper has good absorbent properties.

The required volume may vary depending on the type of water-based paint. Check out the table. It shows the approximate volume.

Acrylic paint consumption rate

The average consumption of acrylic paint for interior work (painting ceilings and walls) is 130-200 g/m2. For painting facades, especially when wet windy weather, more material may be required. On plastered walls, brick and concrete, the consumption of acrylic paint per m2 is greater than on wood or metal.

Alkyd paint consumption rate

The average is 150 g/m2. One liter is usually enough for 10 sq.m. However, these indicators may vary depending on what and in what proportions you dilute the composition - drying oil, kerosene or turpentine. Also, the consumption of alkyd enamel per 1m2 depends largely on the structure and porosity of the base surface. Yes, consumption alkyd paint for metal will be less than for wood or concrete.

The main thing to remember is that it is better to calculate everything in advance than to later run around looking for the right shade or lament about overpaying for extra material.

Water-based paints are used very often because they are relatively inexpensive, environmentally and sanitary safe, and do not produce strong unpleasant odors. They also have a number of other advantages, but even such a perfect and convenient building material costs money. You need to carefully calculate the real need for it, so as not to overpay and not buy it additionally during the repair process.

Peculiarities

The tonality of water-based paint changes quite flexibly, you just need to add color to it. Special additives help avoid peeling, cracking and fading; The applied layer dries very quickly. The emulsion dye easily and comfortably applies to the most different surfaces, even for wallpaper; it is used for painting walls and ceilings.

This type of coating is necessary for both street and interior work. The paint is formed by combining water with specially selected pigments. When the water evaporates, only substances “responsible” for color will remain on the surface. Ease of use, solid protective characteristics, excellent resistance to moisture and ultraviolet radiation - all this speaks in favor of water-based paint. Therefore, it is very important to calculate its quantity and accurately take into account all circumstances and factors.

Great importance when calculating the actual need for paint, the condition of the substrate (previous layer) has. Any manufacturer always writes on the label and on the packaging how much coloring composition needs to be used to cover 1 square meter. m of surface. But all these figures refer only to ideal conditions, and with ordinary renovations in an apartment or house it is rarely possible to achieve the ideal.

Calculation technology

The consumption of water-based emulsion per 1 m2 is also determined by the hiding power of the paint: if this parameter is high, it is sometimes possible to completely cover the darker base with a couple of layers. But there are cases in which you have to paint three times or even more. When applying the first layer, 1 kg of paint can cover 4-5 m2, and when you paint for the second time, you can paint from 6 to 9 square meters with the same amount. m. Remember that rollers with long pile (as well as with any length of pile, made of foam rubber) slightly increase the cost of the paint mixture.

If we look at the tables showing the consumption of water-based paints of various compositions on thoroughly prepared surfaces, we get the following picture (consumption per layers per 1 square meter):

• Silicate varieties - 400 and 350 g.
• Polyvinyl acetate - 550 and 350 g.
• Silicone – 300 and 150 g.
• Acrylic – 250 and 150 g.
• Latex – 600 and 400 g.

But it should be remembered that each manufacturer has its own recipe, technology, and the range of tolerances is also different. And although acrylic paint for interior work is unlikely to be more expensive than latex or polyvinyl acetate, a difference of 10-15% compared to the table values ​​is quite likely.

Helpful Tips:

• The hiding power of water-based paints is closely related to the microclimate in the room. Better conditions– air heating from 25 to 50 degrees, dryness in the room, relative air humidity maximum 80%. Pay attention to the porosity of the surface to be painted: the higher it is, the more paint you will have to use. It is advisable to use a spray gun whenever possible; it allows you to reduce the consumption of the paint mixture by 10% in comparison with a brush or rollers.

• Acrylic paints Not only are they more economical than others, but they also have a longer service life, have an excellent level of protection and are relatively inexpensive. If you do not want to consult with specialists before purchasing paint or decide to check the calculations of consultants and repairmen, online calculators will come to the rescue. They indicate the type of paint mixture, type of surface, number of layers and intended tool.
• When working with a brush, do not make sweeping movements; it is better to spend a little more time, but not to lose valuable material in the form of splashes.

• When painting, press the tool evenly so that all layers are formed of the same thickness. The color consumption rate varies according to the specific tone and specifics of the room. Tinting begins with preparation basic basis, to which the color is added in a few drops. Each time after adding another portion, the composition is stirred until completely homogeneous, otherwise the resulting color may not look as you expect.

• If you have to paint wood, paint consumption should be considered the greatest. IN state standard the nominal value is always mentioned, which is equal to the consumption when painting clean prepared concrete surface. A little more than the nominal amount goes when dyeing plasterboard sheets and designs. It is best to paint metal; this is the most advantageous base material.

• It should be noted that efficiency is not the only important indicator when choosing a painting tool. The brush and roller allow you to achieve relatively High Quality, and if you need to paint narrow ones, hard to reach places, you won't have much of an alternative. The aerosol application method is the most efficient, but the paint costs are very high, and when the slightest mistake the quality of the layer will be unsatisfactory.

Try not to paint in hot weather; the more water evaporates at once, the more material needs to be added to make up for the loss. But air humidity, if it does not exceed optimal value, on the contrary, allows you to reduce the consumption of coloring material.

• Waterproof paint cannot be used at temperatures below zero; attempts to add antifreeze and circumvent this limitation only bring harm. Although the minimum air temperature, according to some manufacturers, may be +3, it would be better not to risk it and work at a minimum of +5. Then you definitely won’t ruin your work and waste paint material in vain.

Remember: even the most trained professionals using water-based paint, deliberately take into account the error in calculations of 5-7% simply because it is impossible to take into account and predict all factors in advance.

• Emulsion paint based on PVA glue is very weakly susceptible to moisture and can reliably protect drywall from it. But if steam is continuously concentrated in some place, the coating inevitably swells and collapses. First of all, such paint and varnish material is used in industrial and other non-residential premises. You can reduce paint consumption by diluting it a little with water. Be careful, excessive dilution will lead to loss of decorative properties.

• To avoid wasting liter after liter, be sure to prime your cement walls, otherwise you will not only waste a lot of paint, but also increase the risk of cracking. Never save on finishing putty; By painting over the starting putty, you will only waste a lot of material. Whenever possible, do not use water-based coloring compounds for treating walls covered with fabrics, unless this is provided for in the design project.

• It is advisable to first prime porous materials (such as polystyrene foam) with a mixture of acrylic primer and water in equal parts, after which diluted polyacrylate paint is applied. This solution guarantees the reproduction of the original structure of the material and a reduction in dye consumption.
