Selection and application of facade paint on plaster. Facade paints for plaster: types and features of use External plaster painting

Facade paint on plaster for exterior work will help make the surface better. Most often, such finishing requires final processing. This will give the house an aesthetic appearance appearance.

The main advantage of painting is that beneficial features finishes are enhanced. It is noted that the paint has:

1. Moisture resistant. Thanks to this property, the walls get wet much less, which means they can stand for a long time.
2. High resistance to impacts environment.
3. Hygroscopicity. The walls do not accumulate condensation, which is formed as a result of the fact that the temperatures inside and outside are different.

Painting prevents harmful bacteria from penetrating the walls and developing. Paint and varnish materials retain their qualities over a long period of time temperature range, which is especially appreciated in regions whose weather conditions are characterized by frosty winters and hot summers.

The colors differ from each other:

• shelf life;
• maximum humidity levels;
• temperature regimes;
• level of biological security.

If painting is done with an expired product, then this composition becomes inelastic and cannot be applied evenly. There are several types of facade paints for plaster for exterior work, namely:

• acrylic;
• silicate;
• silicone;
• cement;
• limestone.

Acrylic paints

This type is the most economical and versatile. The connecting element is polymer compounds, thanks to which the final product becomes strong and reliable. Acrylic types are resistant to adverse weather conditions. They do not freeze in the cold and can be applied at sub-zero temperatures.

This coating protects the façade from bacteria and rotting and is not exposed to sunlight. It has the following qualities:

• does not fade;
• does not crack;
• does not wear out.

These paints should not be used for plaster with sand and lime bases. Silicone compounds are suitable for such cases.

Silicate materials

Silicate materials are based on glass, which acts as a foaming agent. This fact significantly limits the palette of shades. The composition contains mineral pigments and fillers. The advantages of facades treated with this paint are:

• strength;

• durability;
• passive attitude to ultraviolet rays;
• excellent water resistance;
• resistance to various biological influences.

A facade painted with this composition will be ventilated and breathable throughout its entire service life. This means he has nothing to fear from dampness. The approximate service life is 20 years.

The disadvantages are that they are subject to abrasion, mechanical stress. The paint is not elastic and, as a result, cracks. Such compositions are not endowed with thermal properties.

Silicone compounds

Façade is very popular silicone paint. It is characterized by good elasticity and strength. The price of this solution is much more expensive than others, but it is universal. After application, the facade becomes breathable and does not become damp.

Silicone paint stands out because it adheres well to the surface, in addition, it has the following characteristics:

• is not afraid of heat and frost;
• does not fade when exposed to sunlight;
• does not attract dust.

It combines the best properties of the rest decorative mixtures. It may well decorate the facade.

Thick latex structured paints are available for sale. Plasticizers are added to them. Such textured finish is a good replacement for decorative plasters. According to the application method, it represents the “fur coat” type.

Lime-based and cement-based paints

The basis of the lime material is slaked lime. This type of finish is the simplest, so you need to choose carefully. If you save on purchases, you will need significant financial expenses in the future. The walls will need to be renewed every year, as they will begin to get dirty and washed away by rain. The composition is not practical, but its bactericidal qualities and increased degree of vapor permeability are noted. If the facade is finished correctly, then fungus and mold will not appear on it. The color of lime compositions is limited to white and pastel shades. Sometimes bright pigments are added, although this type is characterized by rapid fading; as a result, the building will lose its beautiful appearance.

Cement materials have similar properties to lime materials. The differences are that they adhere better to the base. This quality allows the painted surface to withstand precipitation more stoically. However, such a façade is not resistant to mold and mildew.

Criteria for choosing paint for plaster

When choosing paints, be sure to pay attention to the fact that they come in glossy and matte. This fact gives them different properties. Glossy ones are characterized by greater brightness; they shine in the sun, so it is often recommended to purchase them. The degree of gloss indicates the resistance of the material to dirt. The more gloss there is, the better the dirt will be washed off.

However, you need to be aware of the disadvantages of these compounds. It lies in the fact that for application it is necessary to have an absolutely flat surface, because they show all sorts of imperfections on the plastered wall. Matte products, on the contrary, can hide existing flaws.

Many owners suffer from the fact that the facade of the house loses its appearance after a few months, so they want to purchase facade paint that is highly resistant to dirt and dust. There are no ideal compositions at the moment, but there are those that will help keep building surfaces clean for as long as possible. These facade paints for plaster are capable of forming a hydrophobic shell, which, in turn, has self-cleaning properties. As a result, dirt simply lingers on the surface of the wall, and during the period when it rains, it is washed away.

These properties fully begin to operate 30 days after the coloring is completed. Silicone-based compounds are in first place among hydrophobic products, followed by acrylic and silicate ones.

It is best to use light pastel colors for facade paints for exterior use. In this case, it is easier to choose the color of the roof. The most optimal solution There is an option when the facade of the house is lighter and the roof is dark.

If you are afraid that the house will become expressionless, you can use two shades of the same color. For example, make window and door openings, railings, and footrests lighter. Even a solid and gloomy facade will be enlivened by highlighting some elements.

Using exterior paint in several tones will help emphasize the horizontal division of the wall. In this case, the feeling from the object will completely change. For example, if Bottom part The building is covered with paint that is darker than the top, then the house looks a little longer. The appearance becomes more sophisticated. And when the roof is painted with a dark composition, the building looks more solid. We must not forget that on dark-colored compounds the dust is not as noticeable as on light-colored ones.

To obtain an excellent result, work with facade paint must be carried out in compliance with certain conditions. The temperature outside should be at least 10°C. It is necessary that the surface of the facade is dry. Do not paint after rain or in very hot weather. It is advisable that the surface to be treated should not be exposed to the sun's rays.

Facade paints for plaster have different characteristics and costs, so it is advisable to give preference to trusted manufacturers. To ensure a high-quality and durable coating, experts do not advise saving on this material.

Plasters are the most common and affordable type of cladding for low-rise buildings. They protect walls from moisture, heat loss and minor mechanical damage. The disadvantage of this coating is the lack of aesthetic appeal. Decorate and diversify appearance At home, plaster paints for exterior use help.

The main purpose of the color coating is to complement and enhance performance.

• Waterproof - prevents excessive moisture and destruction of the facade. As a result, the service life of the building increases.
• Vapor permeability – painted walls “breathe” well (allow water vapor to pass through). Therefore, condensation formed due to the difference in temperature outside and inside the house does not accumulate in them.
• Weather tolerance – paints and enamels for exterior use are slightly susceptible to weather conditions. They do not fade under sunlight and retain color saturation for a long time.
• Biological stability - the coating serves as a reliable barrier to the penetration of mold, mildew and other harmful microorganisms into the plaster.
• Heat resistance - the properties of dyes are maintained over a wide temperature range.
• Self-cleaning – they do not hold dust particles well and are easily washed off with streams of slanting rain or water from a hose.

Types of facade paints

1. Acrylic.

The most popular and a budget option. Suitable not only for plaster, but also for almost all types of wall materials. The base contains acrylic polymer, due to which the paints are weakly hygroscopic and highly resistant to abrasion.

Classified by type of base:

• Water-dispersible – have good resistance to high temperatures and the absence of a pungent odor, they are distinguished by a favorable price.
• Organic – suitable for cold weather climatic zones. Recommended for painting worn-out facades with weak plaster. The cost of organic coatings is an order of magnitude higher than water-soluble ones.

The acrylic composition is easily tinted and has a rich color palette. There are no conditions for the growth of microorganisms in the paint, so it is considered completely safe.

2. Silicone.

They are considered the best paint option for the facade of a house. They have multiple advantages:

• Hydrophobicity - rainwater and drops of fog are not absorbed by the painted plaster, but flow down it.
• Vapor permeability - the layer consists of many microscopic pores through which water vapor passes freely.
• Adhesion – high level of adhesion to any type of finish.
• Atmospheric stability - the indicator tends to maximum values. The facade is not afraid of severe frosts and scorching sun.
• Safety – odorless and does not emit toxic substances. Recommended for external decoration of children's and medical institutions.

Most silicone-based paints are water-based. Disadvantages include low wear resistance and elasticity, as well as high cost.

3. Silicate.

The composition contains liquid glass (silicate glue), mineral pigments and filler. Such components provide reliable resistance to ultraviolet radiation and various precipitation (including acidic). Extends the service life of the external coating to 20 years. Disadvantages include weak abrasion resistance and lack of elasticity, which leads to cracking of the plaster.

4. Calcareous.

The basis is slaked lime, which has good vapor permeability and bactericidal properties. On external walls ah, fungi and mold do not settle even in high humidity.

Disadvantages:

• fragility - easily washed off by rain and become dirty;
• limited color range - the palette consists of white and light pastel colors.

5. Cement.

Plaster paints are mineral-based and consist of white Portland cement with the addition of multi-colored pigments. They have higher resistance to humid environments than limestone analogues. They have an almost complete absence of bactericidal properties and resistance to harmful microorganisms. Without a special external coating, walls quickly become overgrown with mold and mildew. Despite their low cost, they are practically not used in private housing construction.

6. Latex.

Managed to gain popularity due to strength, reliability and excellent performance qualities. The base contains acrylate latex, which provides an elastic consistency. After drying, paint with rubber filler forms a thin film similar to rubber on the facade. It fills all cracks, seams and perfectly levels upper layer plaster.

Before buying paints for exterior use, you should carefully study the composition and instructions for use on the packaging. All brands vary in temperature conditions, maximum humidity parameters, biosecurity level.

You need to pay attention to the date of manufacture. The shelf life of outdoor products does not exceed 2 years. Over time, the paint dries out, loses its elasticity and forms an uneven coating when applied.

The surfaces can be matte or glossy. The latter are distinguished by brightness and color saturation. They shimmer beautifully in the sun, but require a perfectly smooth base, as all the irregularities appear on them. Matte compositions look more restrained, but they perfectly hide all the imperfections of the plaster.

In order to get a unique shade, you can buy a base mixture, a set of pigments and mix them yourself.

Consumption

Before starting painting work on plaster, it is important to correctly calculate the required volume. To do this, you need to perform several mathematical operations:

• Calculate total area for painting - first, the area of ​​each wall is determined using the following formula: (length × height) - the area of ​​​​all windows and doors. If the facade has complex geometric shapes, then they are divided into simple rectangles and the area of ​​each of them is calculated. The results obtained are added up.
• Multiply the facade area by the standard consumption for 1 m2 indicated on the packaging.
• Multiply the total by the number of layers (most often by two).

On average, consumption for typical types looks like this:

• 0.1-0.14 l/m2 – silicone and latex;
• 0.1-0.16 l/m2 – water-dispersed;
• 0.5-0.7 l/m2 – acrylic.

When calculating, it should be taken into account that average rate indicated for primed surfaces. Therefore, if you paint external walls directly over the plaster, the consumption will increase. The rarer the coloring composition, the thinner each layer and the higher the quality and uniformity of the coating.

Instructions for painting external walls

The following tools and equipment will be needed for work: a spray gun (pneumatic or electric), a container, a roller with medium-length pile, a wide brush, a spatula, metal brush, scaffolding, stepladder.

Preparation:

• Remove from work surface old cladding, fill cracks with putty and smooth out unevenness.
• Clean areas affected by fungus or mold with a wire brush.
• Rinse the walls with water and dry.
• Cover the façade with penetrating primer to strengthen the surface and improve adhesion.

According to construction experts, it is best to plan work for late spring or early autumn. Usually at this time the air temperature stabilizes within the required limits, and solar activity decreases and does not harm the painted surfaces when drying.

Coloring:

• Mix the paint with a mixer.
• Cover the wall with a base coat. Apply strokes horizontally, vertically and diagonally, constantly alternating directions, this ensures uniformity.
• Leave the façade to dry.
• After 6-8 hours, apply a fixing layer.

According to the instructions, all mixtures are applied 2 times. The exception is lime-type solutions - they are applied three times.

Cost of facade paints

In the construction and improvement of a house, its appearance plays an important role. In order for the house to look good, it will not be enough just plastering work; it should be painted. To make him look attractive and surprise others, you will have to come up with original design and get everyone necessary tools, as well as solutions different colors. Materials that can be used to paint the outer walls of a house are called plaster paints. exterior finishing.

This type of paint is not only used to decorate and create designs for the exterior of a home, but it can also be used to paint walls as a protection for plaster. This mixture does not clog the pores in the plaster layer, due to which it promotes correct process moisture removal. In addition, facade paint on plaster protects the walls of the house from external influences, from temperature changes, precipitation, humidity, and from the appearance of fungus and mold.

There are also varieties of facade paints that protect walls and colors from fading in the sun. All facade paints are divided into several types and subtypes, each with a different composition and characteristics. It is best to select high-quality paints with economical consumption per 1 m2. Having overpaid once, you will be completely confident that the paint will last a long time and will not become heavily soiled or peel off.

What tasks should façade paint perform?

The main question when choosing paint for facade works is: why you should choose paint specifically for exterior decoration and why it is placed in a separate category. The answer to this question is quite simple: facade paint for exterior use, due to its properties, is suitable for more complex work and operating conditions. Such a mixture must be resistant to external influences, weather conditions and aggressive environments. That is why this type of paint has its own separate category and unique composition.

Paint for finishing the external facades of houses must not be subject to:

• To various mechanical stress, cracks, chips and rapid abrasion.
• It is protected from the appearance of harmful fungi, mold, various microorganisms on the walls of the house, and also necessarily contains antiseptic components.
• To ensure that the walls of your house retain an acceptable appearance for as long as possible, without changing their color or fading, you should choose paints with protection from UV filters.
• Also, façade mortar for a home must be resistant to various chemicals and alkalis.
• Required with fire protection.
• The elastic structure of the paint is very important; it will help paint the walls evenly. If the solution lies on the walls correctly and evenly, and is well distributed, then such paint will not peel off in the event of temperature changes or shrinkage.
• With all its positive properties, it should have economical consumption per 1 m2. And suitable for this type of work.
• As you know, the facade of buildings very well collects all the dust and dirt. That is why it is worth choosing paints with an antistatic effect. It should repel all the dust and dirt that usually settles on other types of paint.
• The coating should lie fairly tightly and not show through, so that by painting the facade in two layers, you get a good and reliable decorative coating.

Characteristics of paint during operation

According to operational characteristics, paints can be of two types - these are special weather-resistant paints and those with limited resistance.

If your house has a plastered facade, then in this case You should opt for weather-resistant paints.

These are the paints that are most resistant to any weather conditions, precipitation, temperature changes and will provide excellent protection for your walls and will last a long time and with high quality.

Atmospheric paints are economical in consumption and also have a vapor permeability function, which is an excellent option for working on plastered walls. Thanks to this ability, all condensation that accumulates on the surface of the facade quickly and easily evaporates into the air and does not accumulate under the paint coating. If it is not weather-resistant, then all the condensation tightly sealed under the paint will cause the appearance of bulges and bubbles on the surface, and subsequently damage to the walls.

One more important characteristic for exterior paint is its adhesion.

Thanks to the good adhesion of paint to plaster, it will lay down in a dense layer on every 1 m2, thereby preventing the appearance of paint swelling. This paint is great for applying to walls that have an uneven surface that is completely unprepared for painting.

The main characteristic can also be called the water-repellent properties of the coating. It is very important that the walls do not absorb excess moisture, as this leads to the appearance of fungi, mold, moss and various harmful bacteria. It is also worth paying attention to the resistance of the coating to any kind of mechanical stress. It should not be scratched or crumble at the slightest accidental contact.

Water-repellent paint

What types of paints are there for exterior plastering?

The modern paint and varnish market offers a wide range of paints for any purpose, with any composition and characteristics. It is very important, before making a choice, to decide what goals you are pursuing and what you expect from the paint you need. Everything will depend directly on its composition and characteristics. First, let's figure out what types of paints exist for exterior decoration of houses, and what their composition may be.

Silicate based paints

This type contains a special silicate glue made from liquid glass. The solution is diluted with special minerals and various pigments as a filler. Thanks to this composition, you can be completely confident in the durability of the coating, its strength and resistance to fading, chemicals, humidity and temperature changes.

Silicate based paint

This type of coating can maintain an attractive appearance for more than 20 years; the facade of your home will breathe and push out accumulated condensation. They have economical consumption. The walls will not become damp and will be protected from fungus, mold, etc.

But this paint also has its drawbacks:

• Unresistant to mechanical stress and damage.
• May wear out quickly.
• An inelastic structure leads to cracks and chips.

Lime type

Such paints consist of slaked lime and are the most affordable option for purchase, have economical consumption per 1m2. But, when choosing paint for exterior decoration, you should not skimp. This solution requires constant updating; every year you will have to reapply several layers. It quickly wears out, fades and collects all the dust and dirt. But this coating also has advantages: thanks to its high bactericidal properties, it protects walls from bacteria, fungi and mold.

Cement based

Cement paints are completely similar in composition to lime paints. To diversify the palette, different colors are added to this solution. But this paint, unlike lime paint, has high atmospheric resistance, but minimal bactericidal properties. It is in demand solely because of its low cost, but it is not advisable to use it in the decoration of external facades.

Acrylic paint

The acrylic type of coating is the most popular. This falls exactly into the price-quality category. Acrylic paint has all the necessary characteristics for long service life and retains its appearance long years and has economical consumption. But, like any material, it also has disadvantages - poor vapor permeability.

But despite this, acrylic paint has numerous advantages that outweigh this minor drawback. Their composition may differ, they have paints on water based and organic solvent, which are used for complex work, including external walls with a lot of wear. Consumption 0.6 l. per 1m2.

Silicone based

The best and highest quality are silicone types of coating for exterior finishing. They have a high level of hydrophobicity, are moisture resistant, vapor permeable, and protect your walls from dampness. In addition, they do not fade in the sun, are not afraid of temperature changes and completely repel dust and dirt. In terms of their characteristics and properties they are in no way inferior to acrylic ones. Consumption 0.2-0.16 l. per 1m2.

Facade paint is used for exterior work. It has many advantages, however, buying paint is a thorough undertaking. Let's consider all the nuances of choice, which will allow you to buy high-quality paint and varnish material.

Peculiarities

Facade paint performs two main functions: it improves the appearance of the building and protects the plaster from aggressive environmental influences. Color palette façade paints are varied. Resistance to fading depends on UV resistance. Depending on the type of texture, paint can be:

• matte;
• glossy;
• semi-gloss.

High-quality paint has a lot of advantages, due to which it prolongs the safety of the finished surface of the facade. Let's consider the main advantages.

• Moisture resistance. It is able to retain moisture and prevent it from entering the wall. Due to this, the supporting structures do not become damp or destroyed, and the overall service life of the entire structure is extended.
• Vapor permeability. The property of paint is to allow air to pass through the finished surface. This allows moisture trapped in the wall to evaporate, the oxygen mixture freely penetrates into the building, which has a positive effect on the freshness of the air in the house.
• Resistance to natural phenomena. Important property, which determines the durability of the finish, its ability not to collapse under the influence of rain, snow, wind, and hail. This way the attractiveness of the facade is preserved for a long time. This paint is resistant to temperature fluctuations, its upper and lower limits. This is especially true for regions with hot summers and cold winters.
• Biological inertness and antisepticity. This material eliminates the formation of an environment for the proliferation of microorganisms; the components of the paint are components that are destructive to fungus and mold.

Kinds

On the modern market of finishing materials for facades, there are many coloring compositions. Conventionally, they can be divided into several varieties. Division is carried out according to the main component of the solution, which acts as a binder. Subspecies are differentiated based on additional additives. The following types of facade paint can be distinguished:

• acrylic;
• silicone;
• silicate;
• cement;
• limestone;
• oil;
• perchlorovinyl;
• structural.

Let's take a closer look at each variety.

Acrylic

This paint is a widespread type of facade paint on polymer based. It is divided into two main subspecies:

• water-dispersion (water-emulsion);
• Organic based composition.

The characteristic qualities of acrylic paint are the following:

• it is applied to almost any type of surface (except for lime and silicate, although silicate is allowed for use in rare cases);
• it is characterized by strong adhesion (the strength of the connection with the surface material at the molecular level);
• it sets quickly and has a short drying interval;
• Water can be used as a diluent;
• such compositions are resistant to mechanical loads;
• this paint is elastic; when hardened, it does not shrink or crack;
• it is resistant to ultraviolet radiation and aggressive weather conditions;

Acrylic paint has vapor permeability and high waterproofing properties. It is resistant to alkalis and hypoallergenic (does not contain toxic components, so it does not cause allergies). She has no bad smell. She:

• biologically inert (it is an unsuitable environment for the proliferation of microorganisms);
• easy to clean with detergent and water;
• allows modification of the color shade to the desired one;
• economically beneficial (features a reasonable price).

Silicone

• they fit well on rocks and minerals, plaster;
• they can be applied to a work surface coated with mineral, acrylic or silicate paint, provided that it is intact;
• they are characterized by strong adhesion (it is recommended to carry out work in protective clothing)
• a specific operating condition is an air temperature of more than +2C;
• they are resistant to high and low temperatures (perfect option for regions with extreme temperatures);

In addition, silicone facade paints are distinguished by:

• good waterproofing;
• high elasticity;
• strengthening the strength of the facade;
• resistance to ultraviolet rays;
• long service life;
• good vapor permeability;
• resistance to alkaline compounds;
• dust-repellent surface (self-cleaning due to rainwater and wind);
• biological inertia;
• compatibility with acrylic paint for preparing a solution;
• resistance to shock and vibration;
• matte surface type;
• pleasant aesthetic appearance;
• relatively low consumption;
• average price range.

However, these paints are not very resistant to abrasion. A subtype of silicone-modified acrylic-based paints has enhanced characteristics.

Silicate

This group includes facade paints with a liquid glass base and hardener additives. These paints adhere well to lime, brick, foam and gas block surfaces. They are characterized by weak adhesion to organic coatings and surfaces already finished with silicone or acrylic dyes. They are problematic to remove from the surface, even after a long period of time. These varieties:

• resistant to weather conditions;
• have high vapor permeability;
• fireproof;
• durable;
• have low strength against mechanical loads;
• fade and fade over time;
• inelastic;
• have a narrow range of colors;
• characterized by minimal consumption;
• relatively inexpensive.

Cement

This group includes paints with a Portland cement base. They are well suited for painting on plaster; they lie smoothly on cement-lime and cement-sand plaster. They are distinguished by easy application and high moisture resistance. They:

• resistant to aggressive environmental influences;
• have good vapor permeability;
• allow color changes through coloring additives;
• prone to the appearance of fungus and mold;
• differ high flow rate and relatively low cost.

Limestone

These compositions are façade dyes using slaked lime as a binder. They are produced in the form of a dry mixture, ready-made solutions (paste). Their range of colors is limited to pastel shades; it can be modified with tinting additives, but bright colors quickly fade.

They are easily washed off with water (after the rainy season, the coating will need to be renewed).

The features of such paints include:

• high vapor permeability;
• strong antiseptic properties;
• easily soiled surface (erased when touched);
• high painting costs;
• relatively low cost.

Oily

The category includes coloring solutions based on natural or synthetic drying oil with the addition of a coloring pigment. They do not need dilution and fit perfectly on wooden type surfaces, however they cannot be used to paint alkaline substrates. Their characteristic qualities are:

• high moisture resistance;
• low vapor permeability;
• long drying period;
• vulnerability to ultraviolet radiation;
• short service period;
• relatively low cost;
• wide range of colors;
• excellent appearance;

The cost of painting depends on the darkness of the tone: with its saturation, the number of required layers and consumption increases.

Perchlorovinyl

Structural mixtures

Such Decoration Materials by its nature it is closer to decorative plaster than to paint. The features of such compositions include:

• Ease of use;
• high plasticity;
• elasticity;
• nice appearance and the ability to create 3D effects;
• small variation in color schemes;
• short period of operation;
• high cost;
• possibility of strengthening with acrylic additives.

Consumption

When choosing paint and making all the calculations, it is important to take into account the amount of material that will be needed to cover the entire area finishing works. First, you should calculate the area of ​​the working surface. The area of ​​the wall is calculated by multiplying the length and height. The total amount is obtained by adding the areas of all the walls expected to be finished. The sizes of windows and doors are subtracted from the total amount.

If the walls have a complex shape (with various bends and partitions), it is worth taking measurements with a tape measure.

On the packaging there is an indicator of dye consumption per 1 sq. m. It is multiplied by the total area. If the finish involves a multi-layer coating, the resulting volume is multiplied by the number of layers. To reduce the consumption of facade paint, you need to use a spray gun. Expenses coloring solution depend on the consistency: the thicker it is, the higher the consumption. The standard consumption is indicated for primed walls, the porosity of which is reduced by impregnation. If priming was not carried out, the consumption will be significantly higher.

Approximate consumption various types paint (the numbers are not tied to a specific brand) looks like this:

• acrylic – 140-150 ml. /sq. m.;
• silicone – 130-140 ml. /sq. m.;
• silicate – 100-110 ml. /sq. m.;
• cement – ​​170-200 ml. /sq. m.;
• limestone – 170-180 ml. /sq. m.;
• oil – 100-130 ml. /sq. m. or 1 l/9 sq. m.

To choose a suitable façade paint, it is worth considering a number of factors, starting from the type of work the dye is intended for. If you mistakenly choose paint for interior work, such a coating will quickly become unusable due to the lack of powerful protective properties. The compatibility of the type of facade paint and the type of coating directly determines the durability of the finishing work. For example, acrylic varieties fit well on concrete, brick and wooden surfaces.

Important to consider operational features dye.

• If there is no ductility, cracking over the entire surface is likely to occur during hardening and shrinkage.
• The paint should not contain toxic components that can cause an allergic reaction.
• It is worth paying attention to the drying time, temperature and humidity requirements when performing finishing work.
• The storage conditions of façade paint and its shelf life are important.

When choosing a composition, you should pay attention to the protective properties. It is necessary to take into account the environmental factors that characterize the region, as well as resistance to mechanical stress (impact, abrasion, vibration) and the level of moisture resistance. If the coating does not allow air to pass through, the walls will accumulate moisture and become damp, becoming unusable (the house will be stuffy and a specific smell will appear). The biological inertness of the composition is relevant for areas with high humidity.

In addition, it is worth paying attention to other aspects.

• Resistance to ultraviolet rays (especially important parameter for southern sunny regions, affects color fading and the integrity of the painted surface).
• Resistance to extremes, minimum and maximum temperatures.
• Resistance to aggressive weather conditions (rain, snow, hail, frost, strong wind).
• Fire safety of the composition.
• Resistance to various chemical compounds used for facade cleaning or present in the atmosphere due to emissions from a particular enterprise.
• The presence of antistatic properties (especially important for houses near roads, where dust from passing cars is a constant occurrence).

It is worth paying attention to the aesthetic qualities of facade paint and the warranty period. Whatever the properties of facade paint, if it is designed for 10 years of service, like enamel paint, it will not be suitable for repairs designed for 20 years.

To learn how to choose façade paint, watch the following video.

Facade paint is a universal design solution that allows you to give the exterior walls of your home an attractive look. At the same time, it is also a very practical coating that can protect walls from atmospheric influences and hide defects when plastering walls. The durability of the plaster depends on how correctly the material for painting the facade is chosen. In this article we will talk about what types of facade paints there are, give recommendations for choosing and consider the technology of painting on plaster.

Exterior paint requirements

When choosing paint for plastered external walls, you need to pay attention to the following characteristics: operational, technological and decorative.

Performance properties:

Technological requirements include:

Decorative qualities include:

• Possibilities for tinting;
• Reflectivity (matte, semi-gloss and gloss);

Types of facade paints and their features

The choice does not depend on personal preferences or desires, but on the material of the surface to be painted. A plastered wall, for example, is alkaline in nature, so it will not be compatible with all types of facade paints. By the way, they have several types depending on the binders used in them. Let's consider those that are better suited for exterior plastering work.

Acrylic and latex

Although their names are different, the binder for both is acrylate material. Marble and chalk are used as white filler. Suitable for many surfaces, including concrete, brick and mineral plaster. You can add color using universal water colors and pastes. Due to their low viscosity, acrylates cover the texture of decorative plasters well, such as bark beetle, fur coat, etc. Let's consider the advantages of acrylic and latex paints:

• easy to apply, diluted with water;
• resistance to alkali corrosion makes it suitable for coating plaster;
• bright colors;
• non-aggressive to use;
• water-repellent film, while allowing air to pass through;
• weatherproof and wear-resistant.

Facade latex or acrylic paint can also be used for interior plastering work. The coating is perfect for rooms with high humidity. After drying, the surface becomes matte. Application method: roller, brush or spray.

Silicone

The base is also acrylic resin, but modified copolymer silicone dispersions are added to it. Due to the silicone content, the paint is more resistant to moisture and weathering and can be used for painting plinths and basements of buildings. Overall this is a good choice for exterior plastering work. Peculiarities:

• high vapor permeability rates;
• blocks the development of fungi and mold;
• waterproof;
• high elasticity;
• optimal decorative and operational characteristics;
• applied within two days after plastering;
• high price;
• does not tint into bright, acidic tones.

Silicate

It is produced by mixing liquid silicate glass and organic additives. It has greater strength and wear resistance than others. In terms of performance, this is the best facade paint for plaster. Pros and cons of silicate compounds:

• excellent performance;
• high vapor permeability;
• resistance to mold growth;
• easy application on concrete, brick, cement, lime or gypsum plaster;
• penetrates deeply into the surface;
• low elasticity;
• does not give bright tints, is tinted in pastel colors;
• Not applicable on acrylic plasters and other non-mineral bases.

Oil enamel

Not the most popular paint, with drying oils as a connecting link. It almost does not allow air to pass through and has low elasticity. Therefore, it is used in most cases to work with hard surfaces: wooden, metal. Oil enamel is also used to paint concrete and cement plaster, but the durability of such coatings is low, prone to cracking and peeling. For external plastering work this is far from the best the best choice. Features of oil painting:

• resistance to temperature changes and precipitation;
• poor vapor permeability;
• susceptibility to corrosion, which causes discoloration and destruction;
• toxicity of solvents for oil paints.

Mineral

Limestone. These include, first of all, diluted slaked lime, which is used to paint walls. Simply put, this is whitewashing. Due to its low cost, it gained wide popularity. Its advantages also include its bactericidal effect. Disadvantages of whitewashing: it washes off with water, wears off and gets dirty. Preparing lime dye (whitewash) for plaster is not difficult. . But there are also ready-made paints on sale, for example, Finngard Tikkurila

Cement and cement-lime. Another similar cheap painting option is to use white Portland cement. Although cement paint can be tinted, it will not produce bright colors. To prepare, you just need to dilute the cement with water to a liquid consistency. The advantages include water resistance and quick setting. The disadvantages of this composition are its fragility.

What to paint with?

Summarizing all that has been said, we note that for a beautiful facade made of decorative plaster the choice should be made on one of the water-dispersion (water-based) paints: acrylic, latex, silicone or silicate.

It is difficult to make any rating here. Firstly, manufacturers have different color catalogs, and it’s a matter of taste which paint will be best for you. Secondly, the characteristics of materials vary depending on the additives. Accordingly, the price will also vary.

The cost starts from 180 rubles per 1 liter and up to 600-700 rubles/l. By the way, paints and varnishes may have a high price not only because good quality, but also because they were brought from another country. For example, the popular Tikkurila is produced in Finland. Therefore, to save money you can choose good colors Russian manufacturers, for example Tex, Lakra, etc.

Having chosen what to paint the facade of the house with, let’s look at how to do it

Preparing the walls

Half the battle depends on preparation. Some important steps will allow you to make high-quality painting of plaster.

Checking the reliability of the foundation. The plastered wall is inspected and tapped, chips and potholes are cleaned with a brush. If the plaster has already been painted previously, then check the quality of adhesion of the previous layer. If necessary, it is completely removed. About, how to remove old paint from the facade, you can read it by following the link.

Severe defects are covered with a plaster mixture of the same composition as the entire wall. After drying, the surface is rubbed and primed.

Small irregularities are covered with façade putty.

The finishing putty is rubbed with fine sandpaper until smooth, then primed.

Dry each layer of plastered coating before applying the next one. Before painting, the entire surface of the external walls is primed for better adhesion of materials.

Painting the plastered facade

Painting your house will not be difficult if you follow the recommendations of the paint manufacturers. Plaster on external walls must be completely dry. Air temperature - not lower than 5°C. External work is not carried out when strong wind, rain or fog. Direct sunlight should not fall on the walls to be painted, otherwise their drying will be uneven and this will affect the quality of the coating.

Now look at the order in which they work.
