How to choose latex paint

You need to pay attention to several parameters:

For gloss level.
For the level of moisture resistance and wear resistance;
On the thixotropy index (the number indicates the thickness of the paint).

Gloss can be determined by the following criteria:

90-100 (or SG - completely glossy);
60-89 (marked as G - glossy);
30-59 (semi-gloss - PG);
11-29 (PM – semi-matte paint);
6-10 (matte – M);
0-5 (completely matte - SM).

As for abrasion, this characteristic is also expressed in numbers. Any instruction contains this information - usually the label says something like this: “number of abrasion cycles 3000” (the minimum value for applying paint to walls). Here, the higher the number, the stronger the paint.

Important! Some manufacturers indicate the level of abrasion not by numbers, but by classes. The first class is considered the most durable, and then the higher the number, the less durable the paint in front of you.

Well, moisture resistance is determined even more simply - moisture-resistant paint is simply written on the can or bucket, or it is intended for use in dry rooms. By the way, as a rule, the price for moisture-resistant materials is slightly higher.

An example of a label indicating that the paint is moisture resistant

In general, there is nothing else to pay attention to when choosing paint.

In fact, the review of the material is completed, but finally you can familiarize yourself with an approximate scheme for applying such paint. Such information will not be superfluous, because if you know how to work with it, then you will decide to buy latex paint faster. The material is really wonderful!

Consumption of water-based paint per 1m2

The quality of the prepared surface - insufficient application of putty and primer makes it necessary to use a larger volume of paint to compensate for possible missing binding elements. The use of a standard construction roller in painting can cause some deviation from the consumption rates per 1 m2 declared by the paint manufacturer. In terms of speed of application and convenience, a roller is the most suitable tool, however, it is not the most economical in terms of material consumption. The problem is that today only the “lazy” do not produce water-based emulsion.

The modern market for such products is overcrowded and it would be useful to pay increased attention to the inscriptions on the labels, the contents of which sometimes contain some inconsistencies

acrylic - the most economical;
silicone - occupies the second position in terms of consumption;
silicate – third place in the economy ranking;
polyvinyl acetate – in fourth place;
latex is at the bottom of the list.
promise of consumption of one kilogram of composition per 15 m2;
while most manufacturers voice an average consumption rate of 1 kg per 10 m2.

After the acrylic water-based material dries, a reliable and durable protective layer is obtained, which is not afraid of mechanical stress and high humidity. In most cases, acrylic paints are environmentally friendly and safe for human health

They are suitable for treating walls both indoors and for façade and street work. First of all, it is important to decide what type of paint and varnish material will be used to paint the ceiling or walls. The characteristics of water-based paints and their consumption are determined by the composition of the material

Here is a list of the main types of water-based dyes and their consumption for single-layer and double-layer application: These water-based mixtures are based on silicone, to which other substances are added, so that after painting the surface remains vapor-permeable. Silicone paints can be used not only for walls and ceilings, they can even be applied to the floor, where they will prevent the appearance of mold and mildew. In stores today you can buy polyvinyl acetate water-based paint mixture that contains PVA glue. Polyvinyl acetate dyes have minimal resistance to moisture.

The consumption of this paint is the same as that of mineral dyes. They include any natural minerals, such as cement, slaked lime and others. These coloring mixtures are used only for internal finishing and are used for application to brick and concrete bases.

Typically, the consumption of water-based paint per 1 m2 is approximately 550 grams, and 350 grams for the second application.

Dependence of paint consumption on other factors

All specified consumption rates are considered standard. Under certain circumstances, these figures may change. Therefore, you need 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 will need to be made. Options applied in one or two layers are considered standard. It happens that work may require more time, but each subsequent layer will require less consumption. This largely depends on the surface. Wood and drywall will require more paint than concrete and brick.

The consumption of water-based paint largely depends on the material of the surface to be painted.

The consumption of water-based paint per 1 m2 is affected by the following parameters:

A tool that is used for work. A simple brush is considered the most economical. A roller has more consumption, but a lot depends on its attachment: a long pile almost doubles the amount of material needed. You can work quite quickly with a spray bottle, but calculating the mixture consumption can be very difficult, especially if you lack experience.
Ambient temperature. High rates lead to higher consumption, because rapid evaporation of the water contained in the composition occurs. Low temperatures have the same effect, because the solution simply cannot adhere to the base.
Humidity. It is quite difficult to carry out work in dry rooms; more paint will be required. This happens because the surface absorbs a lot of water.
Correctness of preparatory procedures. The main thing is to apply putty if the surface has significant flaws, and mandatory priming (in several layers).
Application technology. It is this indicator that receives the least attention, although it is no less important.

Thus, before calculating the required amount of water-based composition, it is necessary to take into account many components. And of course, performing work taking into account the tools and conditions used will require a certain concentration.

Comparison of materials from Dulux, Tikkuril and other popular manufacturers

We paint the walls
Each manufacturer improves the technical characteristics of the material with its specific additives. As a result, the hiding power of similar compositions varies from company to company. The table shows white matte paint for the ceiling.

Firm	The basis	Coverage rates 1 liter, per m2
Dulux	latex	9 — 13
Dulux	water-soluble	7
Marshal VD	water-dispersed	7 — 9
Tikkurila Fincolor	water-dispersed	7 — 9
Tex	water-soluble	4 — 6
Tex	based on latex and acrylic	9 — 12
Beckers	latex	8 — 12
Beckers	water-based	7 — 10

When buying paint, add to the estimated quantity the cost of losses of 5 - 7%, depending on experience and the location of the surface. The smallest for the floor, since there is nowhere for liquid to drip and drain. For walls, consider the tool:

spray gun – 3%;
roller with medium pile 4 - 5%;
brush up to 7%.

The largest amount of the composition is absorbed when applying the first layer. High-quality soil and materials from one manufacturer save their costs and drying time.

Application of PF 115

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

It is possible to combine enamel with other coating agents, such as primer. After application, the coating is not subject to spreading or smearing.

It forms a dense film with a smooth coating.

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

This type of paint is used for work:

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

This type of enamel can withstand high atmospheric loads, such as snow, rain and 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 if a special apparatus is available.

The substance contains the following components:

Pentaphthals, which experts classify as polymer substances.
Resins produced by various, including modified, methods. They allow you to speed up the drying process of the surface.
Semi-dried oils and resins with special composite mixtures in small quantities.

Manufacturers

Below is a list of the best manufacturers of paint and varnish products:

Dufa Superweiss – durable and pure color

Paint is used in small rooms and allows you to visually increase the volume of space.

Caparol CapaSilan - the manufacturer focuses on silicone coating for ceilings. The paint has the ability to cover small cracks up to 2 mm.

Dulux is the best option when painting ceilings

Country of origin: Great Britain.

"Oreol Discount" is a ceiling paint that dries 1.5 - 2 times faster than paints from other manufacturers.

Tikkurila Euro 7 is a very expensive option with excellent product quality. The paint is resistant to ultraviolet rays.
Ceresit CT 54 – paint and varnish products for facade work. The product is endowed with antifungal properties.
SNIEZKA EKO – suitable for use on any type of surface. However, the consumption rate is quite high, which is a significant drawback.
“Expert” – paint from the manufacturer DEKART. The only drawback of the product is its excessive thickness. This can be solved, but this problem is not indicated in the instructions on the package.
“Tex Pro” is a fairly budget-friendly paint option, characterized by the absence of a strong odor.

How to calculate area

To calculate the total amount of material needed for repairs, you need to calculate the area of the surface to be painted. To find the desired value, it is worth remembering the school mathematics course. When painting a ceiling, it is enough to measure its length and width and multiply the resulting values (in meters).

To determine the total area of the walls you will have to make more complex calculations:

An example of calculating the area of a wall with a doorway.

For rooms, multiply the perimeter of the floor by the height of the walls; for facades, multiply the perimeter of the house by its height.
Find the area of all windows and doorways.
If you need to additionally paint niches, ledges, columns or half-columns, calculate the size of their surfaces.
Determine the total area for painting - subtract the second from the first result and add the square footage of additional architectural elements to the resulting value.

After all the calculations, you can begin to determine the consumption of acrylic paint.

Calculation depending on the type of material

The most important parameter that must be taken into account when calculating the required paint composition for facade work is the type of paint. The paint and varnish material is selected depending on the characteristics of your facade. In this case, the consumption for each type will be individual.

Water-based paint

The basis for water-based paint is water, which contains an insoluble emulsion in the form of pigment. After applying such a composition to any surface, the water evaporates and only the pigment base remains in the form of a colored layer.

If you decide to purchase a composition of this type, then you should know that for facade work it is applied in two layers. The time interval between painting two layers should be more than one and a half hours.

Advantages:

resistance to frost;
low water permeability;
lack of response to exposure to ultraviolet rays;
acceptable cost.

The calculation in this case should be based on the fact that about 300 grams of the composition are usually consumed per 1 m2 of the surface of the facade walls. That is, if you need to paint 10 m2 of facade, you will need to purchase at least 3 liters of paint and varnish material.

Acrylic paint

Facade acrylic paint retains color well over time

Acrylic-based paints and varnishes are an ideal option for facade work. Advantages of acrylic painting:

duration of preservation of the bright color and protective properties of the coating;
resistance to aggressive atmospheric factors such as high humidity, wind or direct sunlight;
ease of maintenance, for which ordinary detergents are sufficient;
fire safety;
absolute safety for human health;
versatility that allows you to process any façade surface, from brick or concrete to solid wood.

As a rule, the consumption of acrylic paint is less than water-based paint. Typically it ranges from 150 to 200 grams per 1 m2. A more accurate consumption of façade paint per 1 m2 depends on how bright you want the painted coating to be. You can finally decide only by directly applying the composition to the surface.

If you get the required shade in one or two layers, then per 1 m2 you will need approximately 130-170 grams. If you need to obtain a more saturated color, you will have to count on 200 grams per 1 m2.

Oil-based paints and varnishes

Oil paint consumption depends on the desired color brightness

The oil composition consists of drying oil, color pigments and various fillers. At the same time, fillers can be sold both as part of the paint and in the form of separate solutions. If you are dealing with thickly grated oil compositions, you will have to dilute them a little before applying.

Calculating the consumption of oil paint, like acrylic paint, also depends on the desired brightness of the color. For example, if you apply a small amount of red composition to the surface of façade walls, it will look pink. The standard consumption for painting on plaster is usually 150 grams per 1 m2 and can vary depending on the required color.

Alkyd paint

Alkyd paint and varnish material is based on alkyd resins, which are used in production. Its peculiarity is that for facade work the composition must be diluted with turpentine, kerosene or drying oil. When diluted, each of these components will have an individual consumption of material per 1 m2 of surface to be painted. Therefore, in order to more accurately calculate consumption, you should take into account the number of additional mixtures that are used to obtain a brighter shade.

Traditionally, the consumption of façade paint per 1 m2 of wall surface is small and amounts to about 100 grams. That is, for 10 m2 you will need to spend only a liter of paint. A distinctive feature of the alkyd composition is the creation of a stylish and original appearance. In addition, such paint will protect the facade surface from the appearance of fungi and mold.

Thus, now you know the approximate consumption for each type of paint. At the same time, when choosing a composition for facade work, you need to take into account a number of nuances related to its consumption. This way you will save time and will not have to buy the missing paint. In this case, you will not be left with an excess amount of paint and varnish composition.

Composition and structure of the material

There is nothing difficult to understand here. Because this paint consists of several components - water, pigments and a binder, which is made from pure natural substance - latex .

Typically, this paint is sold in large buckets and is pure white. The interesting thing here is that you can easily create the desired color yourself - for this you buy a color scheme. Kohler is a dye; it is usually sold either in jars or tubes. The more tubes of the same color you add to the paint, the richer it will turn out.

Tubes with color

It is very convenient that thanks to the assortment of colors there is room for imagination - you can experiment with shades and as a result achieve some truly unique effect.

Advice: try to purchase colors and paints from the same manufacturer. Only with this approach can you obtain a color that best matches the sample.

By the way, keep in mind that paint with a latex base cannot be stored in cold rooms due to the specifics of its composition. And especially in those places where the temperature is sub-zero. Therefore, we do not recommend purchasing it in advance, before the start of the winter season, for example.

The composition is more or less clear, now let's look at all the practical properties of this paint.

Recommendations for calculation

Calculating the consumption of paints and varnishes per m2 must begin with determining the actual area, that is, by measuring the perimeter of the room and the height of the walls along their entire length. Amendments are introduced for any:

niche;
column and half-column;
protrusion;
bay window.

The area of all openings allocated for doors and windows is subtracted from the wall surfaces to be covered. As a rule, expensive compounds are applied more thinly than conventional ones, so in the long run they turn out to be even more economical

It is important to understand that the actual amount of paint consumed is always higher than what is written on the label

The only exception would be the case of painting perfectly smooth and well-polished plaster, which was covered with two layers of primer

The density of the surface to be painted, its curvature, the level of roughness, and the quality of the initial preparation must be taken into account. In addition, by painting the surface with different tools, you can achieve very different results.

On average, using 1 liter of universal type paint NTs-132, you can give the desired color:

14 - 16 sq. m. smooth metal wall;
6 - 10 sq. m. rough metal;
4 - 6 m2 of high-quality concrete;
16 sq. m. fresh plaster;
10 sq. m. textured wallpaper.

As for wood, it is somewhat more difficult to calculate the consumption of paint and varnish material - there is no uniform calculation standard. So, when painting a cross-cut, you will need to use the same amount of dye as for concrete. When paint and varnish is applied along the grain, 1 kg of the mixture is enough for 8-10 m2, and if you take hardwood, then for 15-16 sq. m. m. The use of sprayers that create relatively thin layers of paint helps to save money, especially if you add a thinner to the composition. When working with a brush, they spend up to 5% of the paint additionally.

Oil paint consumption per 1m2

Before giving specific numbers, I would like to say that the calculation of oil paint consumption will largely depend on the conditions of its application. Moreover, this difference can be very significant. That is why, to begin with, I will give an approximate figure for the general case, when there are not a large number of factors that strongly influence both the increase and decrease in consumption. On average, to paint a surface in one layer, from 110 to 130 grams of paint per 1 square meter are spent. And then I will tell you in more detail what conditions are needed to reduce consumption, and which ones can lead to its increase.

The consumption of oil paint per 1m2 has its own norms. When calculating the average consumption rate, it is necessary to take into account such factors as: paint viscosity, surface quality and even its original color, paint application method (spray gun, roller or brush), as well as the location of the work (room, street, weather conditions).

Oil-based paint on metal is consumed the fastest due to losses associated with environmental conditions. For example, more paint is used per 1 m2 indoors than in dry, warm weather outside. But at the same time, if the weather deteriorates, the loss of paint on the street increases many times over. In strong winds, rain, and fog, paint is consumed faster than indoors.

As an example, we will look at PF 115 paint.

Paint PF 115: characteristics and consumption

PF 115 paint is used for both external and internal work. This is an enamel paint intended primarily for metal work. The paint box states that it is weather resistant, resistant to wind, moisture and solar radiation. But is it? Partially yes. The fact is that the paint acquires such properties only after application and complete drying. During the application process, paint is influenced by all environmental conditions and its consumption increases most of all in strong winds and bright sun.

For this type of paint, the consumption will be different. Depending on the color of the enamel, 1 liter of paint can be used to paint:

black: from 17 to 20 m2
blue: from 12 to 17 m2
brown: from 13 to 16 m2
green: from 11 to 14 m2
white: from 7 to 10 m2
yellow: from 5 to 10 m2

This type of paint, which has not yet dried, literally evaporates in the sun. And consumption can increase significantly.

In specific figures, these will be very large figures; you may need twice as much paint as when working indoors, or, say, in calm cloudy weather. A smooth, glossy, uniform coating is formed only when the paint is completely dry. At the same time, if you apply too much paint in the sun, the coating will be sloppy and rough, and may subsequently begin to peel off.

This enamel paint is best suited for painting galvanized iron and ferrous metals. But it can also be successfully used for non-ferrous metals. True, in the latter case, paint consumption increases.

Painting tool

A lot depends on what kind of material the paint is applied to the surface. A paint brush, whether natural or artificial, uses more paint than a roller. This is easily explained - the brush is literally saturated with paint. A roller, especially a silicone-based one, on the contrary, is an ideal material for painting metal surfaces.

If you have followed all the recommendations, and the paint consumption still exceeds all imaginable and inconceivable standards, think about it: maybe it’s the paint itself? This sometimes happens with cheap, low-quality paint. The manufacturer sets a lower price in the expectation that the consumption of this paint will be colossal, and ultimately benefits from this. Therefore, make sure that the paint is really high quality, and only then start painting.

Factors affecting paint consumption

The surface on which the use of water-based paints is permissible can be different - from concrete and brick to wallpaper for painting. Depending on the surface on which the coating will be applied, the consumption of the material used also changes. It should be remembered that paint consumption is calculated in kilograms and not in liters, since it is easier for manufacturers to indicate the weight of products than their volume. Construction estimates are also prepared in kilograms, so this measurement method is generally accepted.

Before calculating the required material, it is worth paying attention to the factors influencing the change in paint consumption per 1 m²:

The application method used during the work process. The most expensive is the use of a paint brush. In addition to increasing paint consumption, paint brushes quickly break down due to abrasion, which entails additional costs. Using a roller will significantly reduce consumption and help with more even distribution. The roller coat is selected for the specific material of the surface to be painted to obtain an optimal result.

Spraying is considered the most economical and effective way to distribute paint over a surface - it not only increases the speed of work, but also helps reduce consumption. However, to work with a spray gun you need some experience and skill in selecting pressure.

The environment directly affects the work process. Parameters such as humidity and temperature can change the drying rate, thereby making adjustments to the painting process. High temperatures can speed up the thickening process, while low temperatures impair the paint's ability to adhere to the surface, making it more difficult to apply. In turn, humidity also affects the ability of materials to absorb paint. The drier the air in the room where the work is being carried out, the more paint the surface to be painted will absorb, and this will increase its consumption.
A competent approach to preparing the surface for painting. If you plan to paint on a rough surface, such as putty, it is worth applying a primer in several layers in advance. This will significantly reduce the absorbency of the surface and thereby reduce consumption. If you are painting a textured surface, for example, decorative plaster, you should take into account that patterns increase paint consumption by an average of 20%.

Despite the various factors affecting consumption, when painting with a second layer, paint consumption is reduced. In some cases, it is halved, but this depends directly on the type of water-based paint that is used.

Consumption is also affected by the hiding power of different types of emulsions. Hiding power is the ability of paint, when evenly distributed, to cover the color of the original surface. This parameter directly depends on the additives included in the mixture.

Types of paints

Paint consumption rates directly depend on its type. Some formulations can be applied in one layer, others require more. Below we will talk about the consumption of paint for walls, taking into account these factors.

Acrylic compounds

Water-dispersed materials based on acrylic resins are used for finishing internal and external surfaces. Most manufacturers supply white acrylic paint, which must be mixed with the color before application.

So, to find out the consumption of acrylic paint, you must first examine the packaging. Typically, about 1 liter of material per 8 square meters is required. But taking into account the absorbency of the base and the presence of minor defects, we can say that the actual consumption is 1 liter per 6 m2.
Then you need to count the number of layers. If you purchased high-quality branded materials, then it is enough to apply 2 layers. Economy paints require at least 3 layers. For example, there is a wall to be painted with an area of 10 m2. With a consumption of 1 liter per 6 m2, almost two liters of material will be required. If you multiply the resulting number by the number of layers, you get 4 liters of high-quality material and 6 liters of an economy option.
Next, you should consider the tool used. When using a spray gun or roller, the required amount will not change. If you use only brushes, then you need to add another 15%. As a result, the consumption of acrylic paint per 1 m2 is 4.5–7 liters.

One of the advantages of acrylic compositions is that the consumption when working with a roller and spray gun practically does not change.

Water-based

Paint calculation in this case also begins with the manufacturer’s mark. Under ideal conditions, only 1 liter of material will be required to treat 18 m2 of surface. In reality, this figure will be 9–11 m2. Next, you need to take into account the number of layers and the features of the tool. To reduce consumption, it is recommended to use a primer. It costs much less than paint and varnish, so it will save up to 30% of the budget for material. Also, do not apply the paint too thickly, since its hiding power is low and in any case, up to 3 layers will be required.

Water-based compositions have several types, but the most popular is acrylic paint

Powder

Powder compositions based on polymer components have become increasingly popular recently due to their high performance characteristics. To understand how much of this material is needed to paint one square meter, you need to take into account the minimum thickness of the decorative layer - 100 microns. In most cases, when using light powders, the consumption will be 110–130 g.

Powder paints have high performance characteristics and the same high cost, but they are applied only in a factory using special technology

Oily

The main component of this material is drying oil. After application, the substance polymerizes and forms a film. The consumption indicated by the manufacturers varies from 140 to 250 g per m2. When covering an area with one layer, you will need about 130 g of the substance. Also, different amounts of material are required depending on the color:

white – 1 kg/10 m2;
black – 1 kg/20 m2;
yellow and red – 1 kg/9 m2;
green – 1 kg/13 m2;
blue – 1 kg/17 m2.

Facade

For finishing external surfaces, the same materials are used as for internal ones, so the consumption for one layer is approximately the same

But it is important to remember that external walls require more careful painting, since they usually do not have a perfectly smooth coating. Consequently, approximately 30% more paint will be required than in the case of interior decoration

Modern façade paints are highly resistant to damage, but their consumption is higher compared to interior paints

Drying oil

Sometimes only one material is applied to wooden walls - drying oil. It is also used to create a starting coating before painting. To process one square meter of coating, no more than 130 grams of material is required. Moreover, such a small amount of relatively inexpensive material will save up to 20% of paint.

Drying oil is now used as a primer on wood and as a solvent for oil paints.

Features of acrylic paint

Acrylic-based mixtures are widely used in repair work. They are used for interior and exterior work 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;
quick drying;
When used correctly, significant savings can be achieved.

Pros and cons of silicate paint for facades

The main advantage of silicate paint is its extraordinary moisture resistance, because this is a big plus for painting external facades. Thanks to the thin glass protective film, fungus and mold will not form on the painted wall. Surfaces painted with a silicate paint base can be washed and do not fade. The service life of the coating is up to 20 years.

Silicate paints are resistant to all weather conditions, UV filters and fires. A durable surface coated with silicate paint is not damaged by mechanical damage and exposure to chemical acids. After painting the facade with silicate paint, a protective film is formed on the surface - it is this that protects the coating from moisture.

The main disadvantages of paint are:

difficulties when applying to surfaces with microcracks;
insufficient plasticity of the composition;
are incompatible with other types of paints and should not be applied to already painted surfaces;
you cannot paint metal, stone and ceramics with them;
It is not recommended to apply paint inside residential premises - in the kitchen, in bedrooms.
In addition to the above-mentioned disadvantages, silicate paint is difficult to remove from surfaces; sometimes it has to be removed along with a layer of putty.

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 layer 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. The best conditions are air heating from 25 to 50 degrees, dry room, relative humidity of a maximum of 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 are not only more economical than others, but 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.

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 the optimal value, on the contrary, allows you to reduce the consumption of coloring material.

There are several nuances that allow you to reduce paint costs to a reasonable amount:

Do not use a uniform thick layer (thinning with water, adding PVA glue and creating several thin layers is much more practical).
Each subsequent coat of paint is applied approximately 60 minutes after the previous one.
A primer or other strengthening compound helps reduce the absorption of the lowest layer.

Water-based paints are applied not only to smooth walls and other painting compounds; they are often used for wallpaper for painting. The average consumption is 1 liter per 8-11 square meters. m (depending on the specific material and other conditions).

Conclusion

We looked at what latex paint is, and also figured out what this material is actually made of. In addition, we studied the pros and cons and features of this paint in sufficient detail. We hope that after reading this information you will be able to make a truly wise choice in the store. By the way, if you want to learn even more information about latex paint, we recommend watching the video in this article.

Rules for calculating the amount of paint

The first step is to calculate the perimeter of the room; to do this, multiply it by the height of the ceilings. Next, subtract the area of windows, doors, etc. This gives you the number of square meters that need to be painted.

To find out how many liters are needed, you need to multiply the volume of the composition used (the number indicated on the back of the jar instructions) by the area of the walls. Do not forget that this amount is under ideal (or close to ideal) conditions.

Surfaces

When painting the walls in an apartment, this issue may not be so relevant, however, in apartments there are decorative elements made of various materials. In addition, this example shows how much the consumption depends on the roughness of the walls.

Paint consumption per 1 sq.m. surfaces:

70-150g wood;
100-150g metal;
150-250g concrete, plaster.

These data are provided for comparison of materials. Since it all depends on the depth of the unevenness, the base for painting, and the type of paint.

An extra layer of acrylic primer can increase the adhesion of the wall and even out minor defects and irregularities. The consumption of the coloring composition in this case is reduced by 13-18%.

When to paint multiple layers

Painting in two or more layers will be required in the following cases:

when working on a wooden surface being processed for the first time;
if you want to achieve a deep saturation of a matte shade;
with a liquid consistency of the composition;
when using bright colors;
when applying one layer vertically, the other horizontally.

Rules for working with latex paint

Painting should be done in approximately this sequence:

We clean the working plane. That is, we remove debris, dust, dirt, remnants of old paint or peeling putty from it.

Preparing the wall

If the base is concrete or brick, then it must be treated with an acrylic primer. This will increase the adhesion strength of the materials, and will also slightly reduce the level of paint absorption. If the surface is wooden, then instead of primer we apply an antiseptic.
Next, it is advisable to apply the first layer of liquid paint to the wall or ceiling. You already know how to dilute latex paint - add a little water, stir the mixture and apply it to the surface using a brush or paint roller.
We wait until the primer layer is completely dry, and then we apply another, full layer, to which it is no longer necessary to add water.

Painting the wall

And a few words about coloring. This is not difficult to do - a certain number of tubes of dye are added to a bucket of paint, and then mixed with a drill with a mixing attachment. The amount of color is also easy to determine - as a rule, a table is given along with it that shows how many tubes are needed for such and such a color.

That's all!

Let's summarize.
