What paint to choose for the facade on plaster. Facade paint for plaster for exterior work

Exterior finishing is an important component of construction, and every owner wants to get a beautiful and tidy house, but at the same time save money on finishing materials. Painting the facade over plaster is the cheapest and easiest way to improve the exterior of a building. Even a person inexperienced in painting science can cope with such work, and in today’s article you will learn how to choose façade paint and apply it to the walls.

Not just any paint is suitable for painting facades. Before deciding on the color and cost of the material, you need to understand that there is construction paint for internal and external works. In our case, we need compounds for external use, since any others are not able to withstand specific operating conditions: temperature and humidity changes, exposure to ultraviolet radiation, etc. Regular paint will simply peel off after the first rain or crack when frost sets in, and the work will have to start all over again.

So, we need paint for exterior use, but there are some nuances here too. For example, different formulations may differ in their range of temperature stability. So, if you live in the south, where summers are very dry and hot, it is better to choose a paint that can withstand high temperatures and not fade in direct sunlight. If we're talking about about a house in the northern region, you need frost-resistant paint.

You should also make a choice based on the wall material. For example, to paint the facade of a house made of foam blocks without plaster, you will need good moisture-resistant paint that can mask unevenness and minor cracks on the surface. For concrete walls I need another paint. Usually professional builders follow one simple rule– like plaster, like paint. This means that if the plaster is based on silicone, then silicone paint is also needed for it, and if acrylic plaster was used for the facade, then acrylic paint must be used. Otherwise, materials that are different in nature may conflict, leading to premature failure of the building.

To better understand the specifics of choosing paints for facade plaster, we suggest considering the properties of various compositions:

Most often, builders choose acrylic-based facade paint for plaster because it is inexpensive, wear-resistant and easy to use.

Calculation of the amount of paint

So, if you have decided on the type of paint for plaster, it’s time to calculate how much it will be needed for the entire facade. To do this, pay attention to the packaging of the selected paint - it always indicates the consumption in liters per square meter of surface in one layer. In some cases, it may be written the other way around - how many square meters of surface can be covered with a liter of this paint.

Manufacturers often write the consumption of the composition in a certain range, such as 0.1-0.25 l/m². A smaller consumption figure here means painting smooth surfaces, and a larger one means rough or unprimed walls.

To save your time, you can go to the website of the manufacturer of the selected paint and search there online calculator to calculate the number of cans depending on the area of ​​the facade. Usually there you need to enter data about the type of surface and its quadrature, after which the calculator will automatically calculate the volume of paint.

To find out the amount of paint yourself, you need to multiply the area of ​​the surface to be painted by square meters by paint consumption, then multiply the resulting number by 2, since you need to apply two layers and add a safety factor of 1.1. When purchasing any building materials, you need to take a little more than the calculated quantity, just in case.

It is clear that painting wooden facades, brick or concrete walls will take a lot of time, and therefore the paint needs to be stored somewhere. To do this, choose a shaded and dry place. Packages should not be exposed to direct sunlight, they should be protected from frost (temperatures can vary from +5C to +27C, detailed conditions storage, see packaging). If you opened new jar and you see that the paint has separated, that is, there is a transparent liquid on the surface, and the pigment has settled a little lower, mix it thoroughly with a stick or construction mixer. This is a completely normal phenomenon and well-mixed paint will fully comply with the stated characteristics.

Applying paint

The durability and quality of exterior finishing is directly affected by the thorough preparation of the base before painting. The façade plaster for painting must match the pigment used and vice versa. This will ensure better adhesion and wear resistance. Any plaster should be pre-primed. The primer in this case will serve as additional protection against dampness and will compact the base.

If you are working on an old wall, check the condition of its plaster layer. Severely cracked plaster should be removed and cleaned. This can be done using strong water pressure or manually with a stiff wire brush and spatula. If you notice places where moss or mold has accumulated, clean them and treat them with an antiseptic. If you don't do this and simply paint the wall with fresh paint, after a while the mold or moss will grow again and destroy the finish from the inside. All cracks, holes and chips in the wall should be repaired with putty. The same goes for areas with peeling plaster.

To determine how strong the wall of the house is, and whether it needs strengthening and new plastering, stick a piece of ordinary transparent tape on the surface, smooth it well and tear it off with a sharp movement. If there are pieces of the wall left on the adhesive tape, then the base is weak and needs to be strengthened - remove the old plaster and apply new one. If the tape remains relatively clean, you can begin priming and painting.

The technology for painting facade plaster comes down to the following:

1. A freshly plastered facade should be left for 30-60 days to dry (the period depends on weather conditions, the thickness of the plaster layer and the characteristics of the plaster itself).
2. Apply primer. If you are working with an unplastered house made of sand-lime brick, its walls can be coated with a colorless protective primer and only then painted. However, regardless of whether there is plaster on the facade or not, it must be primed.
3. Facade painting.

The only material that is better not to paint is facing ceramic bricks. But this is not because the paint will not stick to it - it’s just that such a material in itself is quite beautiful and self-sufficient. If you are working with a new house made of baked bricks, it is better to plaster and paint the facade as quickly as possible so that the surface brick wall no efflorescence appeared.

Priming the wall

Many people do not understand or underestimate the importance of priming before painting a wall. The primer composition works as follows: it penetrates several centimeters deep into the wall and hardens there, filling microcracks and forming on the surface protective film. Thus, the wall material becomes denser, stronger and adheres better to paint. Because all the cracks and pores wall material filled with primer, the surface becomes smoother and absorbs less moisture. Moisture is present in any paint, and if the base is too porous, it will quickly be absorbed, and you will need several times more paint.

The primer significantly reduces the consumption of facade paint by clogging pores and cracks in the plaster and wall. Its cost is much lower than that of the cheapest facade paint. The choice of primer should depend on the paint composition used. Usually this information is indicated on the packaging. Ideally, you should use primer and paint from the same manufacturer.

Helpful tip: To improve the quality of your painting, use a primer in the same tone as the color of the exterior paint. In some cases, instead of a primer, you can use the exterior paint itself, diluted with water in a 1:1 ratio.

After priming the surface, leave it to dry for 1-2 days.

Selecting Tools

As you understand, painting the facade is a very labor-intensive undertaking, and the narrow paint brush this is clearly not enough. However, the choice of tool for applying primer and paint depends on the consistency (degree of viscosity) of the composition, as well as the characteristics of the surface texture and your skills in this area.

The most common tools are brushes and a roller. If you are working with fairly smooth walls, choose short-haired tools. A roller is much more convenient in this regard and will allow you to finish the job faster with less paint consumption. A brush may be needed for painting hard-to-reach places, for example, near doorways, behind pipes, at the windowsill, etc. If you are working with textured plaster, use a wide paint brush with long bristles.

A few words about spray guns. These devices allow you to quickly cover large areas with paint, but the dye consumption increases significantly. Spray guns are convenient to work on textured surfaces, but this will require a little practice. There is nothing complicated in the work, it is only important to understand how to control air pressure and learn how to handle the tool. This will take an hour of your time and some paint. Here it is important to choose the right paint viscosity and sprayer nozzle diameter - if the paint is too thick and the nozzle is too small, it will simply clog.

Painting technology

When you have prepared the plaster paint for the facade of the house, primer and tools, you can get to work. If you're painting the walls of a low-rise home, you'll need a stepladder. However, constantly rearranging the stairs is very inconvenient and tiring, so ideally it is necessary to build scaffolding (made from boards or rented from a specialized company). For houses with 3 floors and above, equipment for high-altitude work is already required. This is associated with a certain risk, and therefore it makes sense to entrust the work to specialists. Alternatively, you can paint the first two floors yourself and entrust the work at height to a hired worker.

Painting technology:

1. The day before work, check the weather forecast - on the day of painting and a couple of days after it, the weather should be dry and moderately warm. If there is wind, the temperature will drop to +5C or lower. Rain or fog exterior finishing It's better to postpone it.
2. Remove dust and dirt from the surface with a wire brush.
3. Apply primer and let it dry completely.
4. Cover all parts of the facade that should not be painted (windows, slopes, blind areas, etc.) with polyethylene or masking tape.
5. Apply the first coat of paint to the wall, being careful not to take long breaks from working. Here it is better to work with several hands so that there is no difference in color shades and stains.
6. Apply the second coat of paint after the first has completely dried. Drying time depends on the composition of the paint and is indicated by the manufacturer on the packaging.

Helpful advice: To avoid having to wash your brush or roller of paint every time you take breaks from work, wrap them in a plastic bag - this will prevent the paint from drying out.

Painting facades on plaster is not only one of the cheapest and easiest ways to get a beautiful and original house. Properly selected and high-quality applied paint will provide additional protection from moisture and extend the life of the walls of the house.

Any building facade needs not only decorative cladding, but also protection from mechanical, atmospheric and climatic influences. Facade paint can give the house a unique look, set a unified style for the entire yard and at the same time protect the foundation from various biological formations, as well as changes in temperature, humidity, sun rays. There are many varieties, but each has individual characteristics and operational parameters. What will help you choose? Study of the main types and TOP paints for facade work.

Features and types

Facade paint differs from traditional paint in its increased wear resistance, as well as its resistance to temperature changes, frost, and humid or too dry environments. In addition, the composition of such products includes many protective components against the formation of mold, mildew and other biological growths. Thus, the façade of the building will retain its operational properties and attractive appearance for a long time.

The material is found on the market in four interpretations based on the following components:

• lime- used, as a rule, for restoration work, when painting of architectural structures with limestone cladding is required;
• acrylic- acrylic facade paint is applied to a cement-limestone base in the form of plaster on concrete base or brickwork;
• silicone- silicone paint is intended for cladding sand-lime brick or base pre-treated with organic dyes;
• drying oil- oily components are used for painting wood materials, they are able to protect the base from destructive atmospheric and climatic influences.

Separately, it should be noted that silicone facade paint and acrylic can be tinted in any desired color, which is very convenient when creating a single landscape design. To make the right choice in favor of quality products, use the ratings of dyes compiled on the basis of real reviews from consumers and specialists with construction industry.

High-quality facade paint should have an ultraviolet filter, maintain an integral structure during temperature changes and not chip at the edges. On average, the shelf life of the coating is 5-7 years, after which the base needs to be re-coated.

Can be applied to concrete, brick or plaster. Water is used as a diluent. The work uses a brush, roller or a special sprayer. Allow 2 hours to dry between coats. A product weighing 14 kg costs 1,200 rubles.

Facade paint - how to dilute, how to paint

Each dye has an individual composition. Because of this, it needs to be diluted with different solvents - white spirit, acetone or plain water. This information must be indicated on the original packaging of the material.

Most concrete paints for exterior use belong to the water-based category, which allows them to be diluted using regular clean water. Moreover, after hardening, such a dye cannot be washed off upon contact with moisture. The proportions of the consistencies directly depend on how liquid the material should end up being. As a rule, the figure does not exceed 15% of the total volume.

Water-based paint, according to the majority of specialists from the construction industry, is the most suitable option for cladding a building by home craftsmen with little experience in painting work. It is easy to apply and is not subject to abrasion, weathering, or humidity.

A brush, roller or spray gun is used as working tools. The latter device is most convenient for large-scale work. The material is applied in one layer, then the time specified by the manufacturer is waited for “setting” and covered a second time, and if necessary or if the manufacturer allows, the base is coated a third time.

VIDEO: What is the difference between expensive and cheap facade paint

Plastered external walls always look impressive and neat, the problem is that the coating will need additional protection due to exposure to precipitation.

There are a number of requirements for modern finishing of plastered walls. Below are more details about the main ones.

Considering that the facade of a house, regardless of the area in which it is located, is exposed to precipitation, temperature changes, UV irradiation, and wind loads, you should select a paint that can withstand all these tests and protect the walls from destruction.

In addition, it is important to choose materials that can protect the facade of the house from the formation of fungi and mold while maintaining the selected color. Conventionally, the requirements for facade paints for plaster can be divided into decorative, operational and technological.

Performance characteristics of materials for finishing plasters

Facade materials from this category for finishing plastered surfaces can be of limited durability and weather resistance.

Facade painting can only be done in cases where both types of materials have the following properties:

1. Vapor permeability– walls treated with the mixture should not lose their ability to “breathe”, meanwhile preventing the penetration of moisture into the base and the beginning of the process of its destruction.
2. UV resistant– exposure of the coating to the sun should not lead to the paint splitting into its components.
3. Lightfastness– this parameter is responsible for protecting the base from premature fading while maintaining a bright and rich color during use.
4. High adhesion rates– the paint must have excellent adhesion to the base of the plaster, not peel off, and not form blisters.
5. Biosecurity– facade paint should not give microorganisms and mold a chance to develop, protecting the facade of the house.
6. Resistant to mechanical damage– the coating must be resistant to impacts, scratches, and not susceptible to chipping.

Technological characteristics of paint for plaster

An important point is the covering power of the material or its consumption per unit area. In many ways, this indicator depends on the composition of the paint, the characteristics of the pigment, and the sizes that make up the particles. The higher the hiding power, the less paint will be used during the finishing process.

No less important indicator– these are the painting qualities of facade paint.

It is important that the mass is as homogeneous as possible, with optimal thickness for applying it without splashes, lumps or smudges.

Drying time is the quality of the material, especially important for people who need to carry out work in short time. In many ways, this indicator depends on the season and weather conditions; this should be kept in mind when choosing a product for finishing.

Decorative characteristics

Facade materials for finishing plastered surfaces must be susceptible to pigmentation. Products must be tinted in different shades.

Also important point- This is the ability to reflect light rays.

Based on this criterion, materials can be divided into matte, glossy and semi-gloss.

The most reliable, forming a dense film, are glossy facade paints that can transform the facade of a house. Surfaces finished with such materials get dirty less and are easy to clean. In the sun, surfaces glare, due to which you can hide minor defects facade. It is better to use matte and semi-matte paints.

Acrylic for plaster cladding - features

Acrylic paint is considered the most suitable option for finishing plastered facades. The binding element in it is polymers, which are responsible for the weather resistance and strength of the base.

Acrylic paint is simply tinted, so it can be painted in any color or shade. Acrylic facade paint will not become a source of bacterial growth, so the material is considered completely safe for health.

Acrylic paint of the first type can be applied to the facade of a house even in winter, especially when low temperatures. Acrylic paint quickly creates a protective layer on the base, even if it has not had time to dry.

Water-dispersed facade paints for finishing plastered facades are completely odorless, have high adhesion to surfaces, and allow you to create reliable protection for base walls.

Painting with such materials is more affordable, so they are used more often than other types.

Silicate and silicone finishing materials for plaster

If painting a plastered facade involves a textured treatment or with a tinting effect, then a good option would be silicate paint, which is based on binders - “ liquid glass"and a number of fillers.

Painting with materials from this category will require preparation of the substrate and care during the application process.

Silicone facade paint is considered the most modern today and has managed to combine the qualities of all the products mentioned above.

Silicone paint is nothing more than a solution of silicone resins, which can be used to create a waterproof film that protects the facade of a house. The material has increased adhesion and can be painted on any type of plaster.

The silicone wall demonstrates excellent hydrophobic properties - after hardening, water simply flows down along it without penetrating inside, while vapor permeability remains at the same level.

The silicone base exhibits excellent elasticity, tightens quickly, lasts a long time, maintaining a rich color. Just like acrylic facade paint, the product is easy to use, but is sold at a high price and this is its main drawback.

A striking example of silicone paint, which is actively used for finishing modern plastered surfaces, is Tikkurila.

The main advantages of the material are relatively affordable price, a wide range of colors and the ability to use at low temperatures when you need to finish the facade of a house.

Tikkurila demonstrates resistance to corrosion, is resistant to mechanical damage, moisture penetration and chemicals.

The disadvantages of the coating include the volatile components included in its composition, which can be instantly ignited with toxic effects.

In addition, it is difficult to call him the longest-lived. On average, Tikkurila will last on the basis of the facade for no more than four years.

Tikkuril paint is not elastic enough, so over time cracks form in the coating.

To make the facade of the house more decorative, it is customary to use structural paints, the difference from ordinary ones is their thick consistency due to the presence of plasticizers in their composition. The material is in many ways similar to decorative plaster, but is distinguishable from it in price.

Having the skills to apply the product to walls using a roller, brush and spatula, you can create a unique surface, and it doesn’t matter whether budget acrylic paint was used or Tikkurila, which is popular today. The most budget options are paints based on lime and cement with the addition of pigments.

Bark beetle surface coloring

How to paint plastered textured facade bark beetle type houses?

The optimal solution would be silicone paints, which, as mentioned above, incorporate best qualities from all types of materials.

You can paint bark beetle walls in the so-called “one pass,” that is, using paint of the same tone. This option is simpler and is considered a classic.

It is more difficult to paint bark beetles in two tones. To do this, apply light paint to the base of the surface, then wait for it to dry completely and apply paint a tone or several shades darker to the protruding surface of the bark beetle.

This way you can paint surfaces with your own hands and this method is called “dry brush”. As an option, it is permissible to paint bark beetles with gold, bronze or silver paints to create an unusual effect.

To soften the color contrasts on the surface of the bark beetle facade, you can additionally rub the paints, for example, using a rubber sponge or a regular mitten.

These same materials can be used to create a relief surface or a “antique” effect.

Painting bark beetle plaster involves a number of specific nuances. Be sure to start painting with textured areas and only then begin with smooth ones.

In this case, you should wait until the textured areas are completely dry. If we ignore this fact that

Facade paint for plaster for exterior and interior use are different compositions, in which the emphasis is placed on certain qualities that meet their scope of application. Thus, painting facades requires a mixture that is resistant to moisture, temperature changes, ultraviolet radiation, etc. For interior spaces, vapor permeability and safety are important.

In this article we will look at both types of paint for plasters. Also here we'll talk about the process of painting walls with their preliminary preparation.

Painting plastered facades

Facade paint for plaster for exterior use, or rather its quality and correct application, has a great influence on the service life of the plaster. Therefore, saving in this case can lead to even greater expenses.

Types of facade paints

• Acrylic-based compositions. Good adhesion to walls and a high degree of protection from external influences. Biostability is quite high. The most common options are water-dispersed. Organic ones are less common acrylic paints. They all tinted very well.
• Based on Portland cement. Moisture-resistant and inexpensive paint, but the level of protection against fungi and mold is low.
• Lime paints for facades on plaster. Vapor permeable, with high biosecurity. Suitable for painting on the damp surface of fresh plaster.
• Silicone paint for plaster for exterior use. An acid-resistant, water-repellent film of silicone resins is created on the surface. The vapor permeability of the walls will be average, the same as if they were covered with silicate compounds, which will be discussed below.

Paint for the facade of a house on plaster: you can buy compositions with any characteristics

• Silicate paint for external plaster work is weather-resistant due to its composition - calcium borate, alkali-resistant additives and liquid glass. It penetrates deeply into the surface, protecting it well from atmospheric influences, and is quite chemical resistant. Vapor permeability is at an average level. The disadvantage of the silicate composition is the impossibility of tinting in bright colors.
• Perchlorvinyl paint. Its main advantages are low price, wide color palette and the possibility of application outdoors even in cold weather. Has high chemical and biological stability. Disadvantages - it is easily flammable, when painting a facade on plaster it emits toxic fumes and has a strong smell.

Painted house facades

How to choose the right composition

When choosing a composition for painting external walls over plaster, you must remember that: exterior coatings are subject to temperature changes and the composition must have sufficient elasticity; the walls take on atmospheric precipitation - the painting of facades on plaster should be hydrophobic if possible; the surfaces of the facades are not protected from sunlight, which means they must be resistant to ultraviolet radiation; the lower part of walls and the space around doors is often subject to mechanical stress.

Combination of types of plasters with paints

Preparing facades for tinting. Determining the expected consumption of trains

First of all, standard actions are carried out to determine the condition of the plaster itself and eliminate existing defects. The surface should not crumble or become dusty. If necessary, the walls are leveled with putty. Afterwards, a deeply penetrating primer is applied to the walls. You should be very careful with the preparation, as the service life of the new coating depends on it.

To find out the consumption of facade paint per 1 m2 of plaster, you will have to perform simple calculations. We find out the area of ​​each of the external walls of the house and multiply by their number; let's find out total area all door and window openings and subtract it from the area of ​​the walls; multiply the result by the average consumption per 1m2 - you will find this figure on the packaging. If several layers are intended to be applied, then the calculation result is multiplied by their number.

Calculation of area for painting

Technology for painting decorative plaster on facades

First of all, the composition must be mixed - with a mixer or just clean wooden slats. Next, add color if necessary. In cases where the area to be painted is large and several packages need to be tinted, the pigment for each of them is measured exactly by weight or volume so that there are no discrepancies in shade.

When applying the first layer to the plaster, the movements of the brush or roller should be made vertically. The second layer should be applied horizontally, crosswise to the previous one. This way the overlap will be as dense as possible, without stains. You should work quickly, covering as large an area as possible at a time. The day chosen is warm, dry and, if possible, windless.

Painting walls after plastering using a roller

Painting plaster in interior spaces

Paint for interior work plastering is most often used on ceilings in living rooms and general purpose premises. Walls are usually treated in this way in the hallway and kitchen. However, there are exceptions to everything.

Types of plaster paints for interior work

• Water-based paints. Widely used for plastering work. They are easy to work with and there will be no problems with coloring either. Non-toxic, fireproof, no pungent odor, vapor permeable. Resistance to moisture and abrasion is average. Not suitable for use in showers and bathrooms.
• Latex paint for decorative plaster. Thanks to the polymer components, the finished coating is resistant to mechanical and deformation stress. Walls covered with latex paint can be washed using a sponge and various chemicals.
• Acrylic compositions for plaster work. Like latex, acrylic mixtures withstand deformation and mechanical stress well - due to the composite included in their composition. They are tinted well and are easy to apply with both a brush and a spray gun.

Interior paints

• Silicone based paints. Form antistatic, water durable coating with average vapor permeability. Forms good adhesion to any type of plaster and can be cleaned with sponges and brushes. Perfect for showers and bathrooms.
• Oil paints. Provides a washable, matte or glossy surface. Works well on almost all types of paints. The downside is the strong smell during application. The consumption of oil paint per 1m2 of plaster is quite high.

Colored plaster in the interior

Selection criteria and calculation of the amount of paint for plaster inside a house or apartment

Of great importance operating load the room in which you are going to paint the walls using decorative plaster. Thus, compositions for use in the hallway and kitchen must have high resistance to moisture, household chemicals and physical influences. The last two parameters are not important for ceiling treatment. Coloring mixtures for plaster in children's rooms should not only be washable, but also safe.

The higher the vapor permeability of interior paint, the better. In favor of this quality, you can even sacrifice some other parameters when choosing. The use of “breathable” mixtures provides a good microclimate in residential areas. This is especially true for bedrooms and children's rooms.

Green color

The amount of paint and varnish materials is calculated in the same way as for facade work; We calculate the total area of ​​the room, subtract from it the area of ​​window and door openings; multiply the resulting number by the consumption figure/m 2 indicated on the packaging.

Do-it-yourself preparation and painting of decorative plaster

Work to be done:

• Aligning walls vertically and horizontally, if necessary.
• Cleaning and filling of small defects in plaster walls for painting.
• Sanding surfaces first with coarse and then fine sandpaper.
• Dust removal of leveled and sanded surfaces.
• Single or double treatment with a primer, depending on the requirements specified on the paint package.

Applying the composition using a roller

Further work is carried out in the usual manner - with crosswise movements, using paint brush or roller. The softness and length of the pile of the latter is determined based on the quality of the plaster - suitable for smooth coatings foam roller, for embossed ones - with a brushed fur coat.

The construction of a house always ends finishing works along the facade.

One of the options for carrying out such work is painting it, which is done after plastering the walls.

This technique allows you to achieve not only the beauty of the facade, but also protect the walls from the effects of various phenomena.

Paint for facade work must meet certain requirements, and the process itself must be carried out correctly.

When purchasing paint for finishing a plastered facade, it is very important to pay attention to its characteristics, which will subsequently provide a sufficient level of resistance to atmospheric influences and at the same time will retain its properties, regardless of the influence of air temperature, wind gusts and humidity levels.

Performance characteristics

This characteristic is responsible for the immediate durability of the paintwork.

In this regard, materials are divided into two types:

• weather-resistant;
• limitedly stable.

For painting the facade, only the first option is suitable, because Only with its help can you achieve the desired result regarding the protection of the surface of the house.

Weather-resistant paints are characterized by vapor permeability for walls that are treated with plaster. Thanks to this property, after condensation appears on the surface of the facade, it evaporates after some time and does not accumulate under the coating. After all, the accumulation of condensation promises the appearance of bulges on the walls and subsequently leads to the destruction of the coating.

This property is checked after applying a layer of paint and is characterized by the sponginess of the material. This parameter depends on the type of binder that is present in the paint coating.

In addition to vapor permeability, a very important indicator is UV resistance, which are the most susceptible to destruction of the layer. In addition, resistance to sun rays ensures long-term color retention and the paint always looks like it was freshly applied.

Facade painting

The adhesion characteristics should not be neglected., it ensures reliable bonding of the paint and plaster structure on the facade. If the paint has a high adhesion index, then it can prevent the appearance of blisters and bulges. However, not only the properties of the material itself provide good adhesion, but also correct process preparing the wall surface before painting.

Another characteristic is water repellency. This property provides protection to the facade from the appearance and development of fungi, moss and bacteria. Such paints and varnishes repel water, preventing it from being absorbed into the wall surface.

The last performance characteristic worth paying attention to is increased resistance to mechanical damage. It lies in the fact that after applying and completely drying the paint, the material is not subject to destruction, for example, it does not scratch or crumble.

Ease of application

Convenience of applying paintwork is an important factor. V this process . The technology of painting facades on plaster requires the thinnest possible layer when applying the material.

This is explained by the fact that a thick layer of paint chips off very quickly.

The paint must have a property that will not allow it to be absorbed into the wall surface when applied.

Also, this characteristic provides significant savings on the process of finishing the house.. Additionally, such paints are convenient during application in that they do not form smudges or drops.

NOTE!

Considering that paint coatings acquire all their protective properties after complete drying, it must have a high drying rate. This property allows painting to be carried out in any weather conditions, even in late autumn.

Decorative characteristics

This characteristic is important, because the painted facade provides beauty to the entire building. There will be no questions with this characteristic if you select paint with the high characteristics described. This is explained by the fact that the color properties of paint directly depend on its durability.

Correctly selected paint should not change its color during application, nor after some time.

Regarding the texture of paints, they are:

• matte;
• glossy;
• semi-gloss.

Variety of colors

The most suitable for painting a plastered facade are matte paints. They are able to hide any defects that are present on the plastered surface.

Is coloring necessary?

Many people wonder about the need to paint a plastered surface. This question can be answered by taking a closer look at the benefits that such an event provides.

The first and most important property that painting facades provides is its protective function.

Plaster is a fairly vulnerable coating that can allow moisture to pass through and accumulate condensation; it is destroyed by mechanical stress or after prolonged exposure to sunlight.

If mechanical damage or any other damage is fairly easily restored, then the lack of properties such as permeability and water repellency can cause significant damage to the walls of the house. The accumulation of condensation provokes not only the formation of mold and mildew, but also the destruction and rotting of the materials that are in the “pie” of the wall.

If you apply paint to the surface of the façade that meets a high level of the specified characteristics, then many problems can be avoided. An additional advantage of using paint is the ability to create any of the design solutions.

Types of paints

How to paint the facade of a private house? There are several types of paints intended for facade finishing:

1. Silicate. The paint is based on liquid glass, which otherwise called silicate glue, as well as various mineral pigments and silicate type filler. This composition can provide durability, complete resistance to precipitation, even acidic types and is by right the best option . On average, this type of paint can last more than 20 years. Has a high level of vapor permeability. Its only disadvantage is the lack of sufficient elasticity, which leads to the formation of cracks, and after thermal expansion of the plastered surface, marks remain on the paint.
2. Lime. For the basis for the production of this type of paint slaked lime was used. This paint is washed off by precipitation and gets very dirty. Its advantages include high level of vapor permeability and resistance to fungus. Regarding the variety of colors to choose from, it is very limited and is represented only by pastel tones.
3. Cement. The cement variety of paint has all the features inherent in the lime variety, but has more high level of resistance to moisture and precipitation. In addition, it lacks a bactericidal effect, which allows fungi to form.
4. Acrylic. The composition of this type of paint is based on acrylic resins. It has a sufficient level of vapor permeability, but it is significantly lower than that of the silicate variety. It is typical for her low hygroscopicity, but high abrasion resistance.
5. Silicone. This type of paint coating is considered the most a worthy option for painting the plastered facade. Thanks to it, the facade acquires hydrophobic properties, any precipitation and condensation flows down the walls without accumulating on the surface. The silicone variety allows for free diffusion. Adheses well to any type of surface, is resistant to prolonged exposure to sunlight and various adverse conditions. weather phenomena. The paint surface is unable to become electrified, which ensures that dust is repelled and the surface of the façade does not become dirty so quickly.

Specifications

Choose the most suitable option it is possible, taking into account all the nuances regarding the climate of the area in which the house is located, the type of plaster and other parameters. But, as mentioned above, for private construction the silicone type of paint is considered the most suitable, because... it provides complete protection against negative impacts and looks aesthetically pleasing.

Wall preparation stage

Painting the facade begins with the process of preparing the surface of the walls. At this stage, further good adhesion of the paint and varnish coating of the wall is ensured.

First of all, intending to paint the facade, you need to choose the right weather conditions for this. You should choose a day on which rain is not forecast, strong wind or temperature less than + 5 degrees.

The process of preparing the walls is as follows:

1. First you need to remove the paint layer, which is present on the facade (if there is one). It all depends on the type of paint and its condition. If oil enamel was used for painting, then it is necessary to clean the entire surface of the wall. The easiest way to do this is with a hair dryer and a hard spatula. If the acrylic variety was used, then it is allowed to apply acrylic water-based paint on top.
2. Next, you need to assess the condition of the plastered surface.. A wall that is ready for further painting must be leveled, but not get dirty, and when in contact with it, do not leave dust on your hands or crumble. It is recommended that in the absence of the above criteria, puttying of the facade is recommended.
3. Applying primer is a good way to add strength to the plastered surface and increase the degree of adhesion of paint and wall. The soil for such work is selected as a penetrating type.

Facade painting technology

To carry out painting, use a pneumatic or electric spray gun, roller (pile middle length) or with a wide brush. Naturally, you will need to build scaffolding to provide access to the top of the house.

The painting process is as follows (photo below):

1. First of all, the paint is thoroughly stirred using a mixer.
2. It is most convenient to apply paint using a spray gun. However, if there is no such equipment and a brush or roller is used for painting, then paint is applied with strokes. It is recommended to apply strokes in different directions: vertically, horizontally and diagonally. Despite this unique method of painting, it is able to ensure the maximum degree of uniformity of the future coating.
3. All types of facade paints require a two-layer application. The lime variety is applied in 3 layers.
4. The dyeing process should not have too long pauses. The paint, after it begins to dry, subsequently creates a visible boundary between the part of the wall that was painted earlier and, accordingly, later.
5. Applying layers should be carried out only after the previous one has completely dried.
6. After painting, the walls are protected from dust particles and precipitation. To do this, cover them with plastic wrap.

Conclusion

Despite the simplicity of the process of painting the facade of a house on a plastered surface, you should not neglect even the smallest nuances. Each feature in such work is important and ensures a high-quality and reliable result.

In addition to the need to obtain a durable coating that protects the facade, it is very important to carry out the entire process so that the facade also looks attractive.
