Paint consumption per square meter. Paint consumption per square meter Consumption rates of polyvinyl acetate paint per 1m2

Calculation of paint per 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 cheap paintwork 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.

According to 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 that can be applied to fresh, still damp plaster in about a week. Inorganic compounds are less popular than organic ones. 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 gives it an attractive appearance.

The choice of paint is often determined 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 compositions and silicate minerals are used, which are components of a well-designed insulation system for a house built with modern technologies. The easiest way to apply a simple principle when buying paint is that it must be the same type as the plaster.

Acrylic paints

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

Consumption of acrylic paint - 110-135 g / m².

silicone paints

Silicone coating materials are a vapour-permeable product, resistant to solar radiation, which allows the facade to breathe. It protects the walls from the penetration of water from the outside, is not affected by 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 on walls or the facades of historic buildings.

Paint consumption - about 200 g / m².

cement paints

This is a mineral material that is sold in the form of 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, so they are now very rarely used in residential construction.

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 plasters. And it is probably one of the cheapest. In terms of color, she has limited choices.

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

Polysilicate and silicate paints

Silicate paints are quite resistant to moisture compared to lime paints, but have almost identical good vapor permeability. They are highly durable, resistant to mold and the harmful effects of atmospheric factors. Silicate paints are characterized by very high resistance to pollution, the coating is not electrified. A rather limited range of colors is 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 paint consumption on the packaging, then the exact consumption per 1 m² is very easy to calculate. For example, if a consumption of 10 m² / l is indicated, this means that 100 ml of paint will be required to paint 1 m² of wall.

To calculate how many liters (or kilograms) of material you need to purchase 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 carried out with the application of more layers. If the walls are coated with a primer, the manufacturer may suggest that the consumer limit himself to one layer. For calculations made for porous or rough surfaces, approximately 20% more is added to the consumption indicated by the manufacturer on the packaging. Complex moldings and fittings will require additional painting.

Then, to avoid unpleasant surprises during work, the result 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 see that the red square has the same area as the blue triangle. This means that the surface area of ​​a triangular-shaped wall is not so difficult to calculate. Of course, don't forget to measure doors, windows, and other areas that aren't being painted, to subtract the resulting area from the square footage of the job (that's about 10% of the total wall surface area).

Additional factors affecting paint consumption

Manufacturer data

The vast majority of paints are offered by manufacturers in a ready-to-use form. Manufacturers write different data on the packages. In general, this information tells about the necessary precautions, about the benefits, purposes and conditions for using the product. But many of these data affect 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 resistance

Excessive exposure to the rays of the sun causes fading, cracks and swelling of the paintwork. Polysilicate, acrylic and silicone-acrylic paints are the most resistant to UV radiation.

Vapor permeability

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

Abrasion resistance

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 you can apply another layer.

Attention! If a 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 on a flat surface, and a large one - on a surface with a pronounced texture.

Tool selection

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 finished. It is important to follow the manufacturer's recommendations as closely as possible.

Attention! The use of spraying will help to 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 bristle 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 the paintwork material.

Instructions for painting the facade

Work must be carried out under 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

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

Mixtures for leveling walls and ceilings

Step 2. Primer

It is necessary to apply a special primer that matches the selected type of paint. The primer improves adhesion and absorbency, preventing staining caused by uneven paint absorption. Walls coated with a primer are easier to paint, such pre-treatment of surfaces will significantly reduce material consumption.

Step 3. Painting

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

The consumption rates of any water-based paint per 1 m2 need to be known to everyone who is going to use this composition for decorating various surfaces. This will help to correctly calculate the required amount of material and avoid unnecessary financial costs. It is a mistake to assume that everything can be prepared "by eye". This leads to the fact that the quality of work is reduced, and the time spent affects the overall mood.

Before you go to the hardware store, you need to decide what type of material will be used. After all, the specific properties of water-based paint and its consumption largely depend on the composition.

Acrylic resin emulsion

Currently, this variety is considered the most popular. As the name implies, the main component is acrylic resin. Additionally, various additives are added that are responsible for acquiring the composition of the desired properties.

The resulting coating has excellent performance, is not afraid of mechanical stress and moisture. Therefore, it is an excellent way to process the facade of the building.

Acrylic emulsion has a standard consumption per 1 square meter: when applying the first layer - from 180 to 250 g, the second layer will require 150 g. It depends on the base material and application technology.

Silicone based emulsion

Silicone is the main ingredient in this paint. The peculiarity of this variety is that a surface is created that has excellent vapor permeability.

Such paint can be used for application to the floor, it does not allow the formation of fungus and mold. It is also an excellent solution for walls with numerous cracks, no larger than two millimeters in size. Unlike the previous view, this is a good option for interior work.

The first layer of silicone emulsion will require 300 grams per 1m2. For layer 2 with the same parameters - only 150 g.

Emulsions with the addition of silicates

The composition of the material includes liquid glass. It is due to this that the surface is very resistant to various influences.

But even taking into account the long service life, which can be tens of years, the composition does not like high humidity. This limits the scope of its use.

When applying the first layer, 400 g will be needed, the second - from 300 to 350 g per square meter of surface.

Mineral based solution

The composition of such a product contains slaked lime or cement. This material has proven to be exceptionally suitable for indoor applications that have a concrete or brick surface.

The standard consumption rate of such water-based paint per 1m2 is 550 and 350 grams for the first and second layers, respectively.

A polyvinyl acetate emulsion is also commercially available, which includes PVA glue. Such a composition is characterized by exceptional instability to any manifestations of moisture. For 1 square meter, it will require almost the same amount as a mixture based on minerals.

On a note! Currently, there are paints in spray cans. They differ in that it is quite difficult to predict their consumption, even taking into account the standards specified by the manufacturer. In addition, such compounds have a sharp chemical smell.

Dependence of paint consumption on other factors

All the above consumption rates are considered standard. Under certain circumstances, these figures may change. Therefore, it is necessary to work with water emulsion carefully, taking into account various factors.

Much depends on the hiding power that each type of paint has. This feature affects how many layers you need to do. Standard options are considered to be applied in one or two layers. It happens that the work may require more time, but each subsequent layer will require less consumption. A lot depends on the surface. Wood and drywall will require more paint than concrete and brick.

The following parameters affect the consumption of water-based paint per 1m2:

1. The tool to use for the job. The most economical is a simple brush. The roller has more consumption, but much depends on its nozzle: a long pile increases the amount of material needed by almost 2 times. It is possible to work with a spray gun quite quickly, but it can be very difficult to calculate the flow rate of the mixture, especially in the absence of experience.
2. Ambient temperature. High rates lead to greater consumption, because there is a rapid evaporation of the water contained in the composition. Low temperatures have the same effect, because the solution simply cannot adhere to the base.
3. Humidity. It is quite difficult to carry out work in dry rooms, more paint will be required. This is due to the fact that the surface absorbs a lot of water.
4. The correctness of the preparatory procedures. The main thing is the application of putty, if the surface has significant flaws, and mandatory priming (in several layers).
5. Application technology. It is this indicator that receives the least attention, although it is no less important.

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 money 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 substance, there will be too much, but the lack threatens not only to interrupt the workflow, but also to disrupt the identity of the shades on the painted surface.

What can affect paint consumption?

Often on cans of paint they write how much is enough for a certain area. You should not just blindly use such figures, because all average calculations are based on the fact that the walls in the house are perfectly even. In real life, much more paint is needed than stated in the instructions 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

When applying acrylic paint, a variety of tools are used. With the help of 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 occurs according to the same principle.

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

A wide brush is best used to give the wall a scuffed look. To make shading, use hard sponges or plastic trowels.

Standard Flow Calculations

On average, if we are talking about acrylic paint (facade or for interior work), then it takes from 170 to 210 grams per square meter. 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.

Often the premises are of complex configuration, so it is important to take into account the complexity of the "relief". Be sure to follow the plan-scheme during the calculations.

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

Calculation of the amount of acrylic type paint for wallpaper

Acrylic paint for wallpaper has the following advantages:

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

If you need to apply acrylic paints on 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 per square meter.

Not only the consumption of material, but also the structure of the layer 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 long pile of at least five millimeters is selected. More material is used to cover textured surfaces; for painting such planes, a roller is needed with a pile length of at least 25 mm.

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

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 paint and varnish materials are spent on painting the facade per square meter of coloring matter. If staining is done on decorative plaster, paint consumption increases by at least fifty milliliters for every square meter.

When using textured acrylic paint, 40 percent more coloring material should be prepared.

When repairing and supposed paintwork, it is important to calculate the required amount of paint. Despite the indicated information on the packages, the amount of the 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 are.

Different types of paints can be used for painting different surfaces. For example, when painting ceilings, a water-dispersion acrylic composition is most often used. Wood and metal surfaces are treated with various enamels. For facades, special compositions are used that are resistant to water and temperature extremes. One of the most effective for application are powder-type formulations.

Acrylic-based mixtures are widely used in repair work. They are used for internal and external works and are applied to different types of 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;
• fast drying;
• when used correctly, significant savings can be achieved.

Area calculation

If we talk about how to calculate paint consumption, first you need to 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. Then the length is multiplied by the width. All calculations are made in meters.

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

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

Also you can use. To do this, enter the following information:

• the area to be painted.
• paint type
• 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 for approximate calculation only !!)

Consumption rates of paints

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

On the 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 make the necessary tone with the help of acrylic paste. Due to this, such compositions have a rather large color gamut, do not turn pale and do not fade in the sun.

Aerosol acrylic mixtures should be applied to a surface that has previously been treated with primer, varnish and paint from the same manufacturer. Works can be carried out at temperatures up to +50°.

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

The method of application also affects 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 quality solution, two layers will be enough.

When applying a coloring product to cement or plaster, the treated surface is additionally primed. It is worth remembering that for walls and ceilings it is necessary to use different types of acrylic solutions. This is because the paint 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, in order 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 be with a short pile, up to 5 mm. For uniform and economical coloring of a textured surface, it is better to opt for a roller with a long pile, 10-25 mm.

Consumption of acrylic composition during facade work

Based on the characteristics of the texture of the facade, paint consumption per 1 sq. can be 180-200 g per m2 of wall. When 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 select the appropriate tool.

Mixes do not crack and do not burn out. To maintain a beautiful appearance, the surface needs to be updated once every few years.

Consumption of textured acrylic-based paints

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

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

The application of the second layer should be started no earlier than after 4 hours. In order to reduce the consumption of acrylic paint per 1 m2, craftsmen advise working at a temperature regime of + 20 ° and normal air humidity.

In fact, to determine how much paint goes per sq. m, pretty easy. It is important to take into account the characteristics of the coloring composition and the characteristics of the surface to be painted. Everyone should understand how the correct calculation of paint consumption per 1m2 of the mixture will facilitate work and help save money. In many cases, the manufacturer provides information and recommendations for use from which to build. Then we calculate the necessary parameters and get to work.

The quality of the exterior finish of the house is assessed primarily by what kind of paint the walls are painted - color, gloss level, density and other surface qualities that are visible with one's own eyes and make it possible to get a general impression of the level of work performed.

In addition, an important factor affecting the consumption of facade paint is the type of surface. The smoother it is, the less consumption will be, and a rough surface will require more material.(for example, textured plaster "bark beetle" or "lamb" will increase consumption by almost a third of the expected).

Consumption is indicated on the facade paint packaging, but it cannot be taken as the basis for the calculation– in the factory laboratories, the product is tested under almost ideal conditions for temperature, humidity and on a flat, smooth base. In practice, much more material is used, so the indicated value is predominantly of a comparative value.

For other materials

Exterior paint consumption depends on the absorbency and condition of the surface. Therefore, for other materials - for example, etc. - it can be less or more - it all depends on the specific conditions. At the same time, the difference in consumption is not so great, often it is practically not noticeable.

The main parameters affecting paint consumption are not so much the properties of the base material as the type and consistency of the paint itself.

How to reduce material consumption

To reduce the consumption of the coating, it is necessary to choose its consistency correctly.. Too thick material is deposited in a thick layer, the consumption becomes too high, and the thickness of the application can cause wrinkles, cracks or peeling of the film.

CAREFULLY!

At the same time, a mixture that is too liquid is also not suitable - the permissible percentage of adding water is up to 5% (for most materials).

Excessive dilution deteriorates the properties of the film, reduces water repellency, which is unacceptable.

The amount of material used is an important issue. Its solution largely depends on the competent actions of the painter, who chooses the desired consistency of the material. If the density and viscosity of the paint are chosen correctly, then the consumption can be reduced to optimal values, which means cheaper repairs without loss of quality.
