Rating of facade paints for outdoor use. Facade paint for outdoor use: how to choose? Types of facade paints: technical specifications. Foundation preparation process

To give your home a unique look, to make it bright and expressive - every developer dreams of this. Therefore, the work of builders always completes the painting of the facade. Despite the apparent simplicity of this process, its result directly depends on the correct choice of paint.

For each wall material and finish, there are certain types of coloring compositions, the error in choosing which is expensive.

Peeling, uneven distribution of color, cracks in the tinting coating - all these problems are corrected by the laborious cleaning of the facade from paint and applying a new one.

We will talk about what coloring compositions are designed to work with stone surfaces (plaster, concrete, brick), what are their features and performance characteristics in this article.

Classification and properties of facade paints

Before answering the question of how to choose a facade paint for outdoor work, you need to consider the classification of tinting mixtures.

The first level of gradation is the type of solvent used:

• Water;
• Organic liquids (solvent, white spirit, xylene).

Water-soluble facade paints are more popular with developers. Their range is much richer than that of tinting mixtures dissolved in organic liquids. The main motivations for the choice are the lower price and minimal toxicity of water-based paints.

The second, no less important classification factor is the type of binder that forms a protective film. The service life of the decorative coating depends on its mechanical strength, adhesion (strength of adhesion to the base), elasticity, resistance to frost and the sun.

There are several types of binders used for facade paints:

• Cement.
• Lime.
• Liquid glass (silicate).
• Acrylic.
• Latex (rubber).
• Silicone.
• Siloxane.

All types of facade paints have common criteria for assessing operational and technical properties:

Water absorption (absorption capacity)

Facade paint should not absorb a lot of moisture. Otherwise, the walls will get wet, creating conditions for the development of mold and mildew. In addition, on a damp wall, the process of salt release from the solution (efflorescence) is activated and the plaster does not hold well.

The degree of absorption capacity of facade paint is indicated by the water absorption coefficient, denoted by the Latin letter W. Manufacturers indicate its value in digital form (kg / h / m 2 hour 0.5). For high-quality tinting compositions, this parameter should not exceed 0.05-0.1 kg / kg / h / m 2 hour 0.5.

Vapor permeability

This indicator is of great importance for the comfort of living in the house. The paint should not block the exit from the premises to the street for water vapor.

To assess vapor permeability, three equivalent quantities are used:

• The mass of water vapor (grams) passing through 1m2 of a painted wall during the day.
• Vapor permeability coefficient, denoted by the symbol Sd.
• Diffusion resistance coefficient (µ).

High-quality facade paints pass from 110 to 140 grams of water vapor through 1m2 per day.

The second vapor permeability parameter Sd is calculated using complex formulas. For us, only its numerical expression, indicated in the technical description of the paint, matters (optimum 0.3-0.05).

If you are guided by the third criterion, then a coloring composition is considered good, in which the coefficient µ is in the range from 1400 to 1500.

If the facade paint does not pass steam well, then the plaster will become damp and fall off.

Resistance to solar ultraviolet

It depends on it how quickly and intensively the coloring composition burns out under the influence of sunlight. This parameter has no numeric value. Laboratory tests can be considered the only objective criterion. According to their data, silicate (polysilicon), acrylic and acrylic silicone facade paints are the most resistant to the sun.

For frost resistance, manufacturers have not come up with a digital equivalent. This indicator can be indirectly judged by the declared service life of the painted coating.

Consumption

When deciding what paint to paint the facade of the house, you should pay attention to consumption. This is the main economic parameter. It depends not only on the quality of the paint, but also on the surface texture of the wall and the absorption capacity of its material. In this regard, the consumption of facade paint varies in a wide range from 0.18 to 0.7 l/m2. Manufacturers indicate the average consumption on a smooth, primed surface (application in 1 layer).

The amount of paint consumed per 1 m2 of the facade should not be confused with another indicator - hiding power. It shows the amount of decorating composition required for a continuous and uniform coloring of 1 m2. This effect is achieved only when applying paint in 2 layers.

Drying time

With multi-layer staining, the drying time (in hours) is important. Its manufacturers are designated by two numbers. The first indicates the time after which the next layer can be applied (2-5 hours). The second digit determines the time required to achieve operational readiness (at least 24 hours at an air temperature of + 20 - + 23C).

Abrasion resistance only matters for those areas of the painted surface on which people walk. This parameter is measured in friction cycles that a layer of paint can withstand until the moment of complete abrasion.

Our advice: If you are going to paint a cement screed at the entrance to the house, then choose a paint composition with at least 4-5 thousand abrasion cycles.

Facade paint application technology

There are a few simple rules here:

• The surface to be painted must be smooth, sound, clean and dry. Therefore, the first stage of preparation is the removal of old paint, peeling plaster, repairing irregularities and cracks, cleaning the walls from dust and other contaminants, washing the surface with water and drying it.
• The quality of adhesion of the paint composition to the facade material (adhesion) directly depends on the use of impregnation that holds the surface layer together. Therefore, the obligatory procedure is the treatment of the walls with an impregnating composition suitable for the paint used (in 2 layers with an interval of 6 to 8 hours).
• Painting starts from the upper sections of the walls, moving down. For better hiding power, the applied strips of paint should cross.
• It is desirable to do the work without interruptions in order to avoid the appearance of color transitions.
• Optimum quality is achieved when applying paint in 2-3 layers.

Well-known manufacturers, approximate prices and consumption

The market does not experience a shortage of facade paint manufacturers. Store shelves are full of labels and brand names. The leading positions here belong to companies whose products have earned a reputation for consistently high quality among buyers.

The products of the Russian company Lakra Synthesis, which produces the popular line of facade paints Parade and the domestic paint and varnish brand Tex, look worthy against the background of eminent Western competitors.

The estimated price of high-quality silicone paint (1 liter) starts at 300 rubles. Siloxane most often costs more than 350-500 rubles / l. The cost of silicate (polysilicon) paint - from 240 rubles.

Lime coloring compositions produced by well-known brands are not cheap. Their average price is 260 rubles per liter. For comparison, let's say that the same amount of good acrylic paint can be purchased for 200 rubles.

Dry cement and cement-lime paint for facades can be bought for 140 rubles.

In general, it can be noted that the prices for paints of the same type may differ significantly depending on the manufacturer and the region of sale. In addition, the volume of purchases plays an important role, here, as a rule, the more you take, the cheaper.

The average consumption of a facade coloring composition on a primed non-porous surface, according to manufacturers, is from 0.18 to 0.25 liters per 1 m2.

The choice of facade paint

For ease of choice, we have summarized in one table different types of facade surfaces and coloring compositions that are optimally suited to them.

To give the surface an original appearance, so-called structural facade paints are used. They differ from standard ones in higher viscosity, which allows using a spatula, brush or sprayer to decorate walls with various patterns and textures.

When determining which facade paint is best, you will come across such obscure labels as water-based, water-dispersion, perchlorovinyl, latex or rubber paint.

You don’t have to worry about the terms water-based and water-based. This name indicates the state of aggregation of the binder in water (“liquid in liquid” and “solid in liquid”), which does not affect the performance of paints.

Perchlorovinyl paint refers to solvent-based compositions. Simply put, it is not diluted with water, but with xylene or solvent. Its main advantage over water formulations is the possibility of application in the cold season (from -20 to + 4C). Solvent-based paints should not be used at higher temperatures, as the quick drying of the solvent will cause stains on the façade.

Latex and rubber paints are twins. For their manufacture, the same acrylic latex (artificial rubber) is used. It gives the dried paint layer high elasticity, adhesion, resistance to cracking and vapor permeability.

If in the decoration of the facade of your house you have already finally opted for facade paints, then the only thing left is to decide on the option of a specific paint for a practical and high-quality finish. Particular care in the choice of paints for outdoor repair work is dictated by high requirements for it. After all, such paint must withstand temperature changes, precipitation, and even mechanical impact, such as hail.

Facade paints: what is it and what are the types

By and large, in their composition, facade paints contain binders with suspensions of pigments, fillers and solvents, which give the paints auxiliary performance and characteristics. Like others, this type of paint is divided into groups. These are primarily two main groups:

The first group of paints contains such low-toxic and toxic substances that have a dissolving function: white spirit, solvent or xylene. These substances, in addition to toxicity, are also weakly resistant to fire. Among other things, such paints may contain thermoplastic acrylic resin, which is excellent for film formation, which is a very important factor for exterior-painted house walls. Due to their toxicity, such paints are bought less often than those belonging to the second group.

Paints belonging to the second group are more popular, and their range is wider than solvent-based paints. Subgroups of water-soluble paints are divided according to the effective substances contained in them, which each perform their own function when working with such paints. These are the following subgroups of water-soluble facade paints:

Some of them are more in demand, some less. It all depends on the disadvantages and advantages of a particular paint, as well as on their performance characteristics and the desired result of painting and wear resistance of facade paint.

Advantages and disadvantages of facade paint

Organic

Advantages: high quality weather resistant coating, applied at low temperatures (down to -20 degrees Celsius);

Disadvantages: highly toxic and flammable, also much more expensive than water-based paints.

Acrylic

Advantages: resistant to temperature extremes, rain, hail, etc., economical and practical to use;

Disadvantages: There are no particular shortcomings, except for one - they practically do not lie on the concrete surface.

Siloxane

Advantages: thanks to emulsified resins, the coating painted with such paint does not let vapors and water through at all, does not create surface tension during painting of the plastered surface;

disadvantages: the high cost of the cost of such paints.

silicate

Advantages: great for painting houses where there is water or moisture nearby, because they are maximally vapor-permeable, allowing moisture to pass through, allow walls or other surfaces to breathe, resistant to the development of fungi and mold, easily applied to concrete, brick, lime and plastered surfaces;

Disadvantages: do not have elasticity, and therefore do not fill cracks in the plaster.

Lime

Advantages: environmentally friendly, well associated with lime plaster, so that the coating becomes durable;

Disadvantages: time-consuming to prepare, limited coatings and substrates, good only for lime plasters, which are rarely used today.

The best paint for the facade is the one that emphasizes the features of the structure and will keep its color for a long time. Such facade paint can be used both for outdoor work and for interior work too. This is especially true for unheated rooms, because according to the characteristics, it perfectly tolerates high humidity and temperature changes. How to choose facade paint and apply it correctly, we will consider today.

A variety of dyes can be used to paint a building. This is decorative facade paint, and others. When choosing, you need to look at the characteristics of the coating, this is reflected in the instructions and, after choosing, apply it qualitatively.

After all, its durability will depend on it. And now what kind of paint is better for the facade, let's take a look at examples and choose a material from what is presented on the retail market.

Types of paints

Before starting repair work, the question arises of the materials that will need to be purchased.

Consider some types and properties of paints:

• Which paint is resistant to facades directly depends on the composition of the dye. The most important element in the composition of other paints and varnishes is a binder or film-forming material. He is responsible for the quality of such coverage. Thanks to this component, when covering hard places, after complete drying and evaporation, a hard film is formed, which creates adhesion to the substrate, or, in other words, good adhesion of the paint and the surface.
• Paints are distinguished by the solvent used and are distinguished by organic and water-soluble.

Water-dispersion dyes

This water-based façade paint contains binder fine particles that are dispersed, in other words suspended in water. Materials of this kind for facades are produced on the basis of water dispersions.

So:

• In manufacturing technology, synthetic polymers or copolymers, silicone resin emulsions are used.
• The main privilege of such paints is the absence of toxins. In addition, they are perfectly diluted with water, which allows you to get the desired consistency. And the drying time of such paints does not last long at all.

mineral paints

As mentioned earlier, mineral paints do not harm humans. Coloring with mineral-based facade paint has a lot of advantages in relation to other dyes. But here you need to understand that the composition of the facade paint of this material is different and is divided into several subspecies.

lime paints

The main element in the composition is slaked lime.

So:

• The high wear resistance is achieved by the carbonization of the lime, which is created in contact with air. Lime paints are marketed as ready-made pigmented mixtures or pastes.
• Then, before the start of the repair work itself, pigments are added to them, which have good resistance to alkaline substances. For this reason, the presence of a variety of colors of such paints is impossible.
• In terms of cost, lime paints are among the most inexpensive. This is due to the fact that the strength is relatively low. Because of this, they are not often used, but in some situations there is a need to use them.

silicate paints

Let's take a closer look at this.

• In the composition of such paints, the main element is potassium silicate, another name is liquid glass.
• This type of paint also has a small selection of color palettes. Applying them is quite difficult, so most often they turn to professionals for such work.
• The wall must be prepared, silicate paints are not compatible with other types of paints that have been used to paint the wall before. It is allowed to use such paint only on a layer of the same type and, as an exception, lime-based paint.

The price of this dye is high, but the durability compensates for this disadvantage.

cement paints

Here the main component is Portland cement:

• In this type of paint, pigments are used that are highly resistant to alkalis.
• About 15% lime is added to increase the water-retaining properties. And in order for the property of increased weather resistance to appear, 1% of hydrophobic elements are used.
• The advantage of these paints: weather resistance, vapor permeability and suitability of substrates are the same as for lime materials.
• There are disadvantages of materials - this is the presence of fragility, and as a result, peeling of paint over time.

Pay attention to the location of the house relative to roads with heavy traffic, if there is heavy traffic nearby, it is better to choose a material that is resistant to dirt.

Also, the industrial area will have a bad effect on the color of the paint. Of course, there are no paints on the market that do not get dirty at all. But there are types of paints that are suitable even with a strong influence of the external environment.

So:

• For example, if dirt gets on the wall, it can be easily washed off with water, and it will not change its color. Paints of this type are able to create hydrophobic films, they have self-cleaning properties. As a result, all the dirt will not be absorbed into the wall, and change its shade, but will remain only on the surface. To clean the surface, just wash it off with plain water or it will be washed off by rain, which is very convenient and practical.
• Protection against water and external influences increase with time after painting. This period lasts about a month. Silicone paints have the highest hydrophobicity, followed by acrylic and silicate paints. To understand how high-quality the paint is, you need to know the resin content, because this is the main indicator of the effectiveness of the material, but it is not indicated on the packaging.
• The best option would be tested, for example, by your friends, paint. The term for checking the quality of the paint is about two years. If the facade is not dirty and has retained its color, feel free to purchase the products of this company.

Attention: When choosing a paint, an important property will be the degree of gloss. This is important, because the higher this indicator, the better the resistance to dirt. Rain water will more easily wash dirt off the walls. In dusty areas, choose a dark paint, then it will be less noticeable.

• Almost all packages say that it is vapor permeable. Firms try to attract customers with this inscription, to prove to them that their product is the best fit for your home. Because many people are sure that with such properties their walls will be environmentally friendly and benefit the owners of the house.
• But on the other hand, the significance of this property is quite large. Because the tight shell of the façade on the outside can cause steam to condense underneath it, which will move outward and possibly cause the paint to peel off the base. The possibility of such an accident is increased if a primer base was not used before painting.

Foundation preparation process

The result of painting works and their durability, first of all, depend on the preliminary preparation of the base. This step is necessary for both new and painted facades.

Attention: In any case, the primer will give greater reliability to the result. When choosing a paint, pay attention to what type of primer is suitable for it.

• The primer contains a film former, so it does not have a pronounced shade. The result of priming the substrate will result in uniform water absorption of the surface and increase the adhesion of the paint to the wall. Of course, additional purchases lead to unwanted costs, but you should not save on quality, which will pay off over time. Because in the presence of a primer layer, the consumption of paint for the decorative layer will decrease, and of course this tool will make painting easier and faster in many ways.
• Before priming, check the base; during its inspection, no shedding should be observed. The base to be painted needs to look solid and tight, or you'll have paint peeling in the future. In order to check the condition of the base, it is enough to stick a small part of a simple adhesive tape on the wall and tear it off after a while. The adhesive tape should be free of remnants of wall materials, then the base is strong enough.

Color selection

Shops are very rich in the choice of different paints and colors. In most cases, the selection is carried out by evaluating the provided samples. The choice is usually made from two or three final colors. This method is suitable for absolutely everyone, and it is not necessary to be an expert in this field. There are also color palettes in the stores, which will also facilitate the task of choosing.

Attention: In some stores you can take a free or paid sample, which can be applied to the facade and finally decide which paint is suitable.

• You can choose the color for the facade using a computer calculation. A photo of your house is inserted, then the colors are replaced and you can clearly see how the final result will look.
• When selecting material from a sample, it is worth choosing a tone lighter, because on a small surface it will look much darker than on a small part of the sample.
• If in the end you did not choose a color, you can purchase two packs of paint in different shades. Apply them on a large plane and evaluate the options. Don't worry about the first coat of paint in a different tone, it will be completely covered by the final color.

Absolutely all people involved in repair work try to choose the right color for the wall of the building. There are some difficulties with the right combination of colors and elements of the house. Of course, for the perfect selection, you can hire a specialist, but when this is not possible, there are some simple and logical rules.

Let's consider a few of them:

• When painting the facade, choose a light paint, in pastel colors. Such shades are harmoniously suitable for a holistic picture, and in this case it will be easier to choose the color of the roof. To avoid monotony in colors, use several shades of the color used.

• Usually the tone of the wall is chosen less light than the color of the roof. You should not choose opposite colors, but if there is such a need, the intervention of a specialist, for example, a designer, is required.

• You can also consider multi-color facades, but in this case you need to choose the right colors and finishes. It is best to choose a harmonious combination with similar components.

• You can transform any facade by highlighting various openings and other elements of the building. But in this approach, keep an eye on the big picture.

• When painting a building, horizontal or vertical surface planes can be distinguished. This will help to express a unique impression of the architecture. For example, if you paint the upper part of the attic of the house in a dark color, then the building will appear more massive, and if it is light, it will give visual height.

Attention: Do not single out the building from the external environment, this will give greater harmony to the entire landscape.

Which facade paint is better, in your case, you will understand from the above. You can apply any of the compositions with your own hands and this will significantly reduce the cost of work. A video and photo will help you choose the right room design.

When choosing a facade paint, it is necessary to start not from your desires, but from the properties of the material of the wall that will be painted. So, when choosing a paint for a mineral surface, it is imperative to take into account the acid-base nature of the materials from which it is made. Concrete walls, for example, have a pronounced alkaline nature. Plastered surfaces can have an even stronger alkalinity due to the lime often added to them. The brick is close to a neutral environment, but the cement mortar that holds it together also has high pH values. Over time, the surface content of alkalis in plaster or concrete decreases (due to the reaction with carbon dioxide in the air), but you won’t wait a year, and the pH of the wall will still not fall to neutral values.

Oil and alkyd paints are susceptible to alkali corrosion - degradation of the binder, which causes discoloration and even destruction of the paintwork.

It is better to use paints with acrylic or silicone binders, which are resistant to alkaline corrosion and as a result are much more suitable for plaster.

Acrylic paints can be applied without a primer or sealer on a surface that has only been plastered a month ago. For earlier painting (as early as after 48 hours), silicone products can be used, which have a higher vapor permeability and will not peel off the wall when the plaster dries.

Oil paints are perhaps the cheapest and most popular type of materials, where drying oils serve as a binder. Initially, paints were made on the basis of natural (drying) drying oils obtained from linseed or hemp oil (drying drying oils). In order to reduce the cost of paint, semi-drying (from sunflower oil), combined (using volatile solvents), oxidized (oxol) and artificial (also containing solvent) drying oils are currently used, which naturally affects the properties of the paint and its environmental friendliness. Such materials form a fairly dense, poorly "breathable" film and are therefore used mainly for painting wood. The slower the paint dries, the denser the film it forms.

Enamels. Two types of these materials are most suitable for facade work: alkyd (solutions of alkyd resins in white spirit) and polyurethane (based on high molecular weight polyurethane resins). Alkyd enamels create a dense, hard, rather durable, but relatively fragile film on the surface. Polyurethane creates a more flexible and smooth (the painted surface looks like it is covered with plastic), but at the same time more durable and resistant to scratches and impacts with a high gloss film.

Acrylic paints on an organic solvent. Basically, these are matte materials based on polyacrylate. Used for painting plaster and concrete. They form a water-repellent film, which, however, has a high vapor transmission coefficient (“breathable”).

Water-soluble paints are classified as follows:

• paints based on aqueous dispersions of various polymers
• mineral paints

Mineral colors. As a rule, they are used for mineral surfaces (for example, mineral plasters) or surfaces previously covered with the same materials. These include lime paints, consisting of lime milk and alkali-resistant pigments. The strength of the coating is achieved due to the carbonization of lime, which occurs in air. Lime paints are the cheapest. They harden slowly. In addition, they are not resistant to sulfur compounds, which in our time can already be contained not only in urban, but also in "country" air. The strength and durability of the coatings obtained with their help are low. These paints are still used for the restoration and repair of old and historical buildings.

Water-dispersion paints. Their main advantage is that the binders they contain are dispersed as tiny particles in water rather than being dissolved in more expensive, toxic or flammable organic solvents. Water-dispersion materials for facades are produced mainly on the basis of four types of dispersions: polyvinyl acetate (PVA), styrene-butadiene, acrylic, silicone.

Paints based on PVA dispersion are inexpensive, but, unfortunately, they are not waterproof (styrene-butadiene and acrylic paints have much higher water resistance) and therefore simply should not be used as facade paints. True, there are various waterproof PVA copolymers (materials based on them are currently declared as facade), but they are inferior to acrylic dispersions, and their cost is quite high.

Paints based on styrene-butadiene dispersions (they are usually called latex) are inexpensive waterproof materials, but have limited light fastness and therefore should only be used indoors. Nevertheless, on sale you can still find facade paints on this basis, which is unacceptable.

Paints based on acrylic dispersions are more expensive than the previous two, but are the most versatile and therefore especially popular at the present time of all water-soluble paints. To obtain a high-quality finish coating, it is enough to apply two layers to the surface. At the same time, the coating is not only “breathable” (which makes it possible to successfully apply these paints on mineral facades), but also quite elastic. In addition, it has excellent adhesion to the painted surface, resists UV rays well and is durable (up to 15 or even 20 years).

Silicone emulsion paints. They are diluted with water and combine the best properties of acrylic and silicate paints: their vapor permeability is almost as high as that of silicate (hence, they are also suitable for buildings with poor foundation waterproofing), and in addition, they do not support the development of microorganisms. Silicone resin, which is a binder, after drying the paint looks like a natural material - its mineral substructure is related to natural quartz. And at the same time, this beautiful, uniform, matte surface forms a waterproof film.

These materials are suitable for almost all types of mineral surfaces. With their help, you can repaint bases previously covered with both mineral (including silicate) and acrylic paints (by the way, these products themselves can be mixed). Another advantage is high elasticity. Just like acrylic, these paints are non-aggressive - working with them requires the most basic safety precautions. According to experts, silicone paints have optimal decorative and operational properties. Their significant disadvantage is their high cost, which currently limits their distribution.

Silicone-modified acrylic based paints. They also guarantee excellent adhesion and good UV protection. Very resistant to oxidizing agents contained in the atmospheric air, and at the same time retain good vapor permeability. Such a coating dries with less surface tension than even acrylic-based coatings, and therefore does not form microcracks. These paints have positively proven themselves on problematic surfaces (old, weak, repaired using a variety of repair mixtures). They can be applied to almost all substrates available in practice, thanks to which this relatively new product for us is already beginning to gain popularity.

It would be naive to believe that the facade is painted only for aesthetic purposes.

The functionality of paints for facades is much wider than just a decorative coating. They protect the surface of the walls, prevent the appearance of mold and fungi.

The service life of the facade, as well as the costs of maintaining it unchanged, depend on the properties of the composition of the facade paint.

What is needed for

In addition to visible decorative qualities, facade paints have a number of protective properties:

A good paint for facade work creates a reliable barrier against the penetration of moisture from the outside into the walls of the building.

Atmospheric precipitation in the form of snow or rain tends to wash out, crumble small particles of wall material, a binder solution from stone and plastered surfaces, which leads to rapid aging and dilapidation.

Wooden structures from excess moisture begin to rot, warp, deform. But that's not the worst part either.

Freezing water that has entered the thickness of the wall can lead to the formation of deep cracks, chips and shedding of the facade finish.

The painted surface is protected from aggressive chemical attack.

Soil mineral salts, active reagents, which are part of the emissions of industrial enterprises or automobile exhausts, falling on the walls, sharply reduce the strength properties of stone, masonry mortars.

Complex physical and chemical processes in the thickness of the wall can lead to the formation of efflorescence in a short time, and in the future - to a violation of the integrity of the structure, the appearance of karst exfoliations.

Facade paints have an antiseptic, antibacterial effect, prevent the appearance and reproduction of mold, moss, fungi and other forms of biological life on the walls.

Fire retardants, which are part of the facade paint, cannot, of course, completely protect a wooden house from fire, but they significantly reduce the likelihood of wall fires from unforeseen external influences.

The combustion process is significantly slowed down, which gives time to organize fire extinguishing or evacuate people and property.

An important indicator of facade paint is its hydrophobicity.

Preventing the external ingress of water into the thickness of the walls, such a coating gives free access to the atmosphere for gases and water vapor, allows the scrap to "breathe", which has a positive effect on the durability of the structure and comfortable indoor conditions.

Most modern facade paints possess these necessary performance qualities.

Types of facade paints

The structural composition of all paints is approximately the same.

This is a base (solvent), a binder with the ability to film-form, pigment additives that determine the shade of the paint, as well as a whole range of fillers, plasticizers and additives that perform additional protective functions provided by the manufacturer.

Depending on the basis, paints are divided into two large groups, which have different technological and operational indicators.

Organic paints

The basis for paints of this type are organic solvents such as white spirit.

Although many believe that the time for such materials has already passed, they, nevertheless, are included in the range of products of the world's leading manufacturers, since in some cases their use is the only possible solution.

Facade paint on an organic solvent - frost-resistant - work on its application can be carried out even at low air temperatures.

In addition, the protective properties and resistance to precipitation begin to appear even on a coating that has not yet been stabilized, not dried. This makes it possible to carry out finishing work without waiting for the warm season.

When choosing such a paint, it is best to pay attention to the offers of leading manufacturers of such products:

Dulux is a well-known British company offering a range of white spirit based paints in both matt and glossy finishes.

The products meet all European quality and environmental requirements. Each customer can choose the colors of the Dulux facade paint on their own.

To do this, tinting machines are installed in company stores, which, on the basis of colorless paint, will create the required shade.

The average cost of Dulux organic facade paint is from 900 rubles per kilogram.

Duparol - facade paint by Caparol, is an excellent solution if you need to get rid of old stains of mold, dampness, soot.

Available in matte and glossy versions, white or as a basic colorless base with subsequent tinting. The price of such paint is about 500 rubles. per kilogram.

Water based paints

Water-soluble paints are subdivided depending on the binder filler - based on acrylic resins - acrylic latex, based on "liquid glass" - silicate, and based on silicone resins - silicone.

This type is probably the most popular due to its versatility and relatively low price.

They are suitable for any external surface - brick, wood, metal, have good adhesive ability with the old coating, that is, they are suitable for repainting.

Most Popular Brands:

Beckers, Sweden – Expo Fasadakrylat paint is distinguished by its versatility and excellent anti-corrosion performance.

Fits well even on aluminum or galvanized steel. The price of Expo Fasadakrylat acrylic facade paint is about 900 rubles per 1 kilogram of paint.

Alpafasade Polyacryl French paint from ALPA has excellent performance. It is used for painting brick, stone, concrete or plaster.

High weather resistance, water resistance, durability - all this is guaranteed by the manufacturer. The cost of such paint is 350 - 400 rubles per kilogram.

From domestic manufacturers, we can safely recommend the products of the Yaroslavl Paints association.

Facade all-weather paint has all the necessary properties, in addition, it has a very attractive price - only about 1000 rubles per 14 kg. packaging.

Silicate facade paint

Silicate paints have a rather limited use due to their physical and chemical characteristics - the content of alkaline and calcareous components in them.

In addition, their color scheme is not sufficiently diverse.

The surface treated with such a material will not succumb to further repainting with polymer-based paints.

As a rule, they are used in restoration work to give old buildings their original appearance, in which a durable silicate coating is created that has high protective properties and good vapor permeability.

In conditions of individual construction, it is rarely used.

Silicone facade paint

This type has absorbed all the positive properties of both silicate and latex coatings. They are much more elastic, do not have thermoplasticity, and have high vapor permeability.

At the same time, they create a surface that is not wetted by water, which contributes to the self-cleaning of the walls during rain.

When using them, it is not necessary to carry out antibacterial priming of the walls, since all the necessary additives are included in their composition.
