Painting plastered walls. Features of painting decorative plaster indoors and outdoors Facade paint for external plaster work

Manufacturers building materials offer a wide range of paint and varnish products for plastering work. The quality and duration of operation of the painted surface depends on the correct choice of products.

How to choose the right paint for plaster and what characteristics of the material you should pay attention to will be discussed in this article.

Peculiarities

The process of painting plaster is quite simple, but includes several important points that significantly affect the final result.

You need to understand that you should start painting only after completing all other procedures with plaster, as well as after the surface has completely dried.

The coating must be puttied with one mixture before painting. Traces that differ in shade when using different putties may not be painted over even after applying several layers of paint. Also, spots may appear after uneven puttying.

To begin with, it is important to take care of the convenience of the upcoming procedure by preparing the tools without which no specialist will begin work. For convenience, it is best to use long-pile rollers, as well as a tray with special spikes.

Purpose

For finishing facades and painting interior walls, paints of different compositions are used, since the requirements for them differ.

Plaster paint is divided into two types - for interior and exterior use.. It is quite possible to apply each of them with your own hands, without resorting to the help of craftsmen, thereby significantly saving your budget.

For interior work

Plaster paint for interior work– an important component of interior design. From the right choice depends on the quality of ceiling and wall coverings. Currently available on the market a large number of compositions, but it’s not easy to navigate them. For materials used indoors, vapor permeability and grain size are important.

These paints and varnishes are considered durable due to the resin contained in the composition. The film that forms after drying protects the pigment.

It is very convenient to apply special non-drip paint to the plastered surface. For example, to paint the ceiling it will be perfect material. A special jelly is added to the paint, making the composition thicker and evenly distributed over the surface.

When choosing a material for interior work, it is important to take into account some factors, such as room humidity, changes temperature conditions, impact ultraviolet rays. For example, for walls in a garage or cellar, it is best to choose silicate or water-based compositions.

For facade

Not every paint is suitable for outdoor use. It must meet the following requirements:

• High strength;
• Wear resistance;
• Impact resistance sun rays;
• Waterproof;
• Moisture resistance;
• Frost resistance;
• Fire resistance;
• Economical material consumption.

The main purpose of the coating is to strengthen performance qualities plaster.

High-quality paint has a thick consistency and, when shaken, gradually becomes liquid. This is necessary for uniform application of the composition.

Before purchasing, you should carefully study the information on the product packaging. Paints differ from each other in terms of temperature, humidity, environmental friendliness and shelf life.

Today, the following façade plaster paints for exterior use are common:

• Silicate;
• Cement based;
• Acrylic;
• Silicone;
• Calcareous.

By surface type facade materials There are glossy and matte. Glossy ones have a bright and rich color, matte ones are discreet, but perfectly hide the imperfections of the plaster.

Varieties

As mentioned above, there are many types of stucco paint. The compositions of the solutions cover the plastered surface with a protective layer, thereby giving the strength of gypsum or cement plaster. Based on certain factors, paint is selected on one basis or another.

Water-based paint

It is considered one of the most popular and has a number of important advantages:

• Affordable price;
• A variety of colors and shades makes it possible to choose perfect option for every interior. For example, you can purchase colorant and paint white and make the composition of the desired shade with your own hands;
• Easy to paint. All painting work can be done independently.

But this material also has some disadvantages:

• Low moisture resistance. In conditions of high humidity, detachments form on the surface;
• The coating cannot be cleaned or washed.

Acrylic washable paint

It contains an acrylic composite, which provides resistance to adverse external factors. The coating is durable and resists deformation. The solution is water-based, so it can be easily washed off hands and tools. It can be used in rooms with high humidity.

The painted surface can be easily washed with a damp sponge, thanks to which the color and cleanliness will be preserved for many years.

Silicate paint

This type of solution has its own number of features:

• Resistance to precipitation;
• Does not deteriorate under the influence of ultraviolet rays, so the facade remains bright for a long time;
• Vapor permeability.

Silicone paint

This type is known for its highest strength and best performance characteristics. The surface painted with silicone paint repels dust and moisture. The facade can be washed an unlimited number of times without worrying about the coating. The only drawback of such solutions is the high price.

Alkyd and oil paints

Dyes on this basis are distinguished by their rich shades, durable layer and durability, but with all their advantages they also have their disadvantages. These include the high cost of the material, bad smell and high consumption.

If there are metal parts on the walls, then you need to select special paints, such as electrically conductive and fire retardant.

Base type

Manufacturers of paints and varnishes, looking back at trends modern design, began to produce paint with various effects. Thus, it became possible to apply structural drawings on smooth walls and ceiling.

There is a unique type of finishing - Venetian plaster. It is used exclusively indoors. It is made with imitation stone, for example, malachite or granite. There are two types of Venetian plaster - embossed and smooth. Relief contains small granules and therefore the surface becomes textured. Smooth allows you to achieve an original play of light. This visually creates the impression that the wall is made of pure marble.

Venetian plaster can be painted any color. For getting best result You can use a couple of shades at once. An indispensable condition for painting is a perfectly plastered surface.

On sale you can find plaster with a grainy effect. It hides uneven surfaces. This type of plaster can also be colored. To obtain a beautiful effect, after applying one layer of paint to the surface, it is treated with a damp sponge.

Coloring textured plaster has some nuances. In the case when textured and smooth elements are combined on a plastered wall, then work begins with the textured one. Smooth areas are painted after the rest of the surface has dried.

If you do not take this fact into account, then when painting the entire coating, loose parts of the plaster will peel off and stick to smooth elements. When applying a second coat of paint, this rule is not necessary.

To add shine to the surface, beeswax can be applied to painted plaster.

How to calculate the material?

One of the important points when choosing paint for plaster is calculating the material consumption.

To calculate the consumption of facade paint per 1 sq. m, you need to perform simple mathematical calculations. Initially, you need to find out the area of ​​each wall of the house and multiply by their number. Then total area subtract door and window openings from the resulting wall area. The final result is multiplied by the consumption indicated on the packaging with the material. If several layers are applied, the result is multiplied by their number.

How to apply it correctly?

If the base after applying the plaster turns out to be fragile, then it is important to strengthen it with a colorless primer. After this, the process of painting the walls begins. Stir the paint cans well, adding color if necessary. A test stain is carried out on an inconspicuous area to determine whether the resulting color is satisfactory.

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.

An equally important indicator is the painting quality of façade 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 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, characterized by high adhesion to surfaces, allowing you to create reliable protection foundation 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 silico new paint, which is actively used for finishing modern plastered surfaces is Tikkurila.

The main advantages of the material are its relatively affordable price, a wide range of colors and the ability to be used at low temperatures when it is necessary 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. Most budget options- These are paints based on lime and cement with the addition of pigments.

Surface coloring of bark beetles

How to paint the plastered textured facade of a bark beetle type house?

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

Paint for building facades differs in many ways from material for interior work. First of all, it must be as resistant as possible to all external influences.

Moisture, temperature changes, aggressive environments, ultraviolet radiation, mechanical loads - these are the main factors that can quickly destroy a layer of an incorrectly selected coating.

Types of facade paints

Before you decide how to paint the outside of a plastered house, you should learn a little more about what the building materials market offers today.

1. Facade silicate paints. They are based on silicate glue (liquid glass), and the composition is complemented by filler and natural pigments. Plaster painting of external walls will last for at least 20 years. The painted layer is vapor-proof, resistant to ultraviolet radiation and acidic environments.

Note! Disadvantages include poor abrasion resistance and frequent crack formation. The latter occurs due to the zero elasticity of the layer, which is deformed due to thermal expansion. As a result, the owner often observes a network of small cracks on the walls.

1. Compositions based on slaked lime. They perfectly transmit steam coming from inside the room. Fungus will never settle on the walls due to the bactericidal properties of lime. This type of exterior painting of a house over plaster also has disadvantages - it gets dirty easily, is washed off by precipitation, and is poor in color range. White and pale, pastel colors - that’s the whole poor palette.
2. Cement facade paints. The base is made of white Portland cement, with the addition of pigment substances, creating a mixture similar to lime. Moreover, although paints are more resistant to moisture, they are not protected from mold and fungal growths. Therefore, even the low price of the material does not add to it the special popularity that more modern analogues can boast of.
3. Acrylic compounds. Reasonable cost and modern components providing decent performance have placed the material among the leaders. Most varieties are made on the basis of water, but there are analogues using organic solvents.

Before painting the exterior of the plaster, pay attention to its strength. For heavily worn facades, where the plaster is unreliable, solvent-based options are desirable.

The paint is less vapor permeable than silicate paint, but has better abrasion resistance. Durability and the ability to mask minor defects and cracks on the surface add advantages.

1. Silicone paints for exterior use. It is generally accepted that this option– one of the best. The attached instructions justifiably promise whole list benefits.

The coating will become hydrophobic, which means that precipitation and condensation from fog will not be absorbed into the walls, but will flow down. At the same time, vapor permeability will be maintained, which is very important for the microclimate in the house. Micropores formed in the painted layer will not create an obstacle to diffusion.

Adhesion to almost all types of plasters can be called ideal. Ultraviolet radiation and temperature differences do not affect the paint in any way. Dust will not be attracted due to the inability of the façade to become electrified.

The disadvantages include the highest cost compared to previous types, and slightly less elasticity than acrylic paints.

How to calculate paint consumption

To purchase the exact amount of paint required, it doesn’t hurt to do some simple arithmetic.

Therefore, before painting the outside of a plastered house, it is worth calculating the surface area of ​​the façade walls.

1. It is calculated by multiplying the length by the height, then the results are summed up.
2. The sum of the areas of door and window openings is subtracted from the result.
3. For a façade that has a complex shape, all piers and protrusions are measured separately and then added together.
4. The result obtained is multiplied by the average paint consumption per square meter indicated on the packaging.
5. If you plan to cover the walls in two/three layers, multiply the resulting number by the number of layers.

Note! The thinner the consistency of the paint, the thinner the layer will be, which means the material consumption will be more economical. Another nuance is that the manufacturer indicates the average consumption for primed walls. Paint applied directly to the plastered surface will take much more.

Painting works

If you want a surface that won't crumble or fade, inspect the walls before painting the outside of your stucco home. If there is any on the plaster old paint, you will have to find out its type.

Some rules for surface preparation

1. In the case of an identical previous coating, it is permissible to apply a new one without prior preparation. For example, water-based acrylic composition fits perfectly on the same one. If the old paint is a similar color, you won't have to prime it.
2. Oil enamel as an old layer requires preparation. It’s easy to clean it with your own hands, using.
3. Carefully evaluate the resulting condition of the walls. Fragments of old plaster should not lag behind and crumble. No traces of dust are allowed on the palm of your hand running along the wall.

1. If you have the slightest doubt about the strength of the rough coating, it should be puttied. Then prime with a deeply penetrating compound. This will make the surface durable and at the same time improve the adhesion of the new paint. In this case, the grip will be maximum.

Note! Don't neglect the preparation stage. Properly done, it will not require restoration for a very long time.

Painting process

You will need a minimum set of tools.

1. Electric or pneumatic spray gun.
2. Wide brush.
3. Roller with medium pile.
4. Scaffolding or a secure ladder.

Note! After opening a can of paint, be sure to stir the contents. If you have a construction mixer, use it. A regular metal rod or piece of slats will also work.

If this is not done, the mixture will be uneven in color and consistency.

1. When painting with a brush or roller, the direction of the first paint layer should be vertical, and the second - horizontal (crosswise). This way you will achieve an evenly painted surface, without spots or gaps.
2. If you are using lime paint, apply it in three coats. Each subsequent one can be placed only after the previous one has completely dried.
3. All other paints can be applied in two layers, this is quite enough for a uniform color and tone.

1. Try to paint in one go, quickly and without pauses. Otherwise, the dried paint may subsequently differ slightly from later areas.
2. Cover the painted wall with film placed at some distance. This way you will protect the still damp surface from the adhesion of dust, as well as from precipitation.
3. Try to choose warm, dry weather for work. Rain or snow will interfere with the painting and drying process.

Alternative types of formulations

For exterior use, paints of various colors are produced, not only in color, but also in decorative effect. For example, you want the walls to have a slight shine, or vice versa, to achieve a matte surface. This idea is easy to implement, you just need to choose the right material.

Moreover, they also produce a special structural paint, with its help you can achieve a 3D effect on the walls. If applied correctly, it will give the plane a relief, which can then, if desired, be tinted with a different color without painting completely.

Conclusion

Only correctly selected paint and a thorough approach to work will give a positive expected result. If the material is compatible not only with your taste, but also with a well-prepared surface, you will not face any quick restoration work ().

The video in this article will show you how to choose the right paint and apply it in practice.

Plaster is an integral part of any facade, and in construction it also remains. However, for all its functional qualities, it looks rather unsightly in appearance, remaining a gray and ugly mass. And painting the facades on plaster will help correct this shortcoming, which will immediately give the entire building a bright and interesting appearance.

All about paints

What’s interesting is that when talking about façade painting materials, one can emphasize not only the color change that they bring to the exterior, but also the positive practical aspects for the walls of any building.

After all, high-quality paint for facade works for plaster allows you to preserve and increase all the positive aspects of the plaster layer, and these include:

• Strengthening the moisture resistance of walls, which always has a positive effect on the longevity of the building.
• Hygroscopicity. The material does not close the pores of the base of the walls of the house, so steam removal from the premises to the outside functions normally.
• The paint coating gives additional durability to the finish and resists weathering.
• Increases the finish’s tolerance to temperature changes, increasing frost resistance.

• Counteracting the spread of fungus and microorganisms on the surface of the façade.

Important! Thanks to a special color manufacturing technology, the colors of façade paint on plaster do not fade in sunlight, and the exterior design long time operation will be presented in bright colors.

Types

All main types of facade paint can be divided into three types:

• Silicone.
• Acrylic.
• Silicate.

Moreover, each type has its own distinctive advantages.

For example, for acrylic and silicone paints the following can be noted:

• Almost complete absence of pungent odors because the material is based on just water.
• Painting can be carried out in already functioning premises, and not only at the time of completion of construction and finishing work.
• Lifetime acrylic paint for outdoor use about 10 years, and silicone 2.5 times longer.

Important! Silicate paint is based on liquid glass, so it is recommended to work with it with greater caution. But the silicate base of the material copes well with the appearance of small cracks on the walls.

From the point of view of appearance, after application the façade paint Bark beetle on plaster looks interesting. It turns out in the form of corroded tree bark, which is where its name comes from, but in practice, the paint material simply contains a small grain, which is responsible for the effect of the bark beetle.

Application

Naturally, the instructions for painting external walls always assume the complete completion of the main construction and installation work on the object. That is, the roof must already be installed, windows and doors installed, slopes and window sills made, and all necessary communications installed.

There are also requirements for weather conditions and they must be met:

• The air temperature should be consistently positive.
• The average daily temperature at the time of work should not be lower than 10 C.
• Do not apply paint during or after rain.
• The wall surface must be completely dry.
• It is not recommended to apply paint in hot weather, especially in direct sunlight.

Preparation

You can start your preparation by counting required quantity material. It is necessary to understand that increasing the consumption of façade paint on plaster can only be prevented by careful handling of the material and correct calculation of the area.

On average, 1 m2 of plaster can take up to 300 grams of paint, respectively, 1 liter is enough for an average of 3-5 square meters. Here we must immediately make an important clarification, we are talking about consumption when applying one layer! Accordingly, with the second or third layer, the consumption will increase.

Naturally, paint is always purchased with a reserve. This increases the price of the entire facade, but the moment of getting the color is important here, because if the paint runs out at the wrong time, then it will be quite difficult to get the color right and it will be too clearly noticeable on the facade.

After calculating the estimate, you can begin preparing the surface. To do this, the plaster is cleaned of dirt and dust. If there are oil stains on the walls, they must be removed without fail. Over time, oil is bound to seep through any finish.

If there are obvious defects, you can correct them yourself. cement mortars or glue, after all, paint will not hide everything.

Once all the primer coats have dried, which takes a few hours, the paint coating can be applied.

Applying paint

The technology for painting facades on plaster involves three options for applying the material to the surface of the walls:

• A simple brush. The method is suitable for small area, plus the presence of scaffolding is necessary if we are talking about a private two-story house.
• With a roller. The most common method.
• Spray bottle. With this method, paint is simply sprayed in a thin layer over the surface.

It cannot be said that there is a best or most suitable method; each method has its own advantages.

In terms of coloring rules, the following can be noted:

• It is recommended to apply all the material at once and without long interruptions.
• Painting proceeds from top to bottom to eliminate drops and streaks on the finished surface.
• Bark beetle paint is applied, and the grains in the material are responsible for the effect of “eaten bark.”

Conclusion

Everything is good about façade paint, from practical use to appearance. A huge plus is the incredible ease of application ().

All positive traits The video in this article will show the material, and along with the qualities, you can also “spy” on the practical use of paint.

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

For immediate endurance paint coating answers this characteristic.

In this regard, materials are divided into two types:

• weatherproof;
• 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 high rate clutch, it can prevent the appearance of swelling 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 everything protective properties paint coatings are acquired 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 paints for painting plastered facades 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, and is destroyed when mechanical influences or after prolonged exposure to sunlight.

If mechanical damage or any other destruction 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 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 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. Possesses sufficient level 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 worthy option for painting a 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 weather conditions. The paint surface is unable to become electrified, which ensures that dust is repelled and the surface of the facade 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.

It is recommended to apply strokes in different directions: vertically, horizontally and diagonally. Despite such a unique method of coloring, it is able to provide maximum degree uniformity of the future coating.
