Which wood paint for outdoor work is better: the main types of compositions. Facade paint for wood: which one to choose for outdoor work Types of facade paints
Wood is in demand for a reason in the process of building buildings and parallel structures, such as baths, gazebos and fences. This building material, in addition to looking elegant, is also very valuable because of its features. The wood is usually covered with varnish or paint. The latter will be discussed. This article presents the rating the best paints wood for outdoor work for 2019.
The house has been built on the site, now it will protect you from the cold and bad weather. But in order for him to be able to protect you, it is necessary to protect, first of all, himself. Wood is a strong material, but very susceptible to destruction. Rain, frost, temperature changes will quickly turn even boards and rounded logs into a cracked, crumbling mass. In addition, the house must have its own color.
When you see a building, the first thing you remember is its color. And only then - how many windows, doors, floors. Painting for the home is clothing: it decorates and protects. But other wooden structures also need painting. Especially if they are located in the open air: playground structures, wooden bridges, garages, warehouses, bathhouses, etc.
Ordinary coloring compositions will not work here. We need specialized ones that must meet the following requirements:
- Durability. Who needs to repaint a building every year these days?
- Protection of wood against corrosion. The composition must preserve the wood in its original form, preventing cracks, swelling, shedding.
- The ability to keep color for a long time (usually achieved by the presence of a UV filter). Can you imagine the disappointment of the owner who bought a bright purple paint for his house and after a year saw that the color had become pale and barely noticeable under the influence of the sun and rain?
Modern facade paints contain, among other things, antiseptics, flame retardants and water-repellent substances. Oddly enough, anti-corrosion facade coatings were invented quite a long time ago - back in Ancient Rus'. Modern scientists have only improved the technology, but almost did not change it. The long history of facade coloring mixtures is explained by the fact that in Rus' wood was the main building material due to its abundance in this territory. Plus many years of experience in shipbuilding: wooden ships most of all needed external processing.
Types of paints for wood
Not all compounds exhibit the properties declared by the manufacturer. Much depends on the climate of the region, weather conditions and mechanical impact on the surface to be painted. Therefore, you should not blindly trust advertising, you need to try everything from personal experience or learn from the experience of those who have checked it all themselves. You can also see the rating of wood paints for outdoor work in 2019.
Protective and decorative coloring mixtures for wood for outdoor use are divided into:
- Water-based acrylic
Such paint forms a thin layer after drying. protective film over its entire surface. This film is very elastic, does not crack, does not collapse, while "breathing", i.e. skips steam. Resistant to temperature extremes. Widely used for facades wooden houses, fellings, lining, block houses.
- Water-based latex
Such paints are very resistant to mechanical abrasion, almost do not fade and form a very elastic coating. Acrylic resins are added to the composition of such paints, which provides even greater strength and elasticity. The addition of synthetic latex significantly improves appearance colors, making them bright and visually silky. Great for wooden house facades, window frames, doors, fences and wood.
- Alkyd mixtures
Paints based on alkyd resins, which, after drying, form a dense protective glossy film that protects against temperature extremes and moisture. The disadvantage of such compositions is their rather rapid fading. If you buy such paints, then colorless or obviously pale tones. Frames are painted with such compositions, wooden doors and any surface where protection is more important than a beautiful lasting color.
- Oil paints
One of the first paints used for wood, although they are ineffective for wood: they do not hold low temperatures, lose color and quickly become unusable. They are bought only in cases of total shortage of funds for more expensive formulations. In general, oil-based coloring compositions are best left for painting fences, fences and flagpoles.
The best manufacturers of facade paints for wood
Usually, all manufacturers talk about the presence of the above qualities in the compositions they produce. But in practice, the rapid loss of parameters in the actual environment of use is noticeable. Below are the highest quality coatings from leading manufacturers, as well as carefully analyzed the characteristics of each composition.
10th place: Yaroslavl colors
Yaroslavl paint and varnish plant specializes in the production of various coating compositions for surfaces: varnishes, antiseptics, primers. One of the most popular products is Tekotex paint. Rather, a protective-toning mixture for wood. The composition based on alkyd varnish, solvent and fungicides forms a completely reliable protection of wood from external influences and gives it a lasting color.

If you live in a region with a mild climate, you can safely buy paintwork data. The product is not recommended for residents of the northern regions.
It is worth noting that the manufacturer is more popular with a range of compositions for preparing wood. For example, cleaning mixtures are in demand by many buyers involved in construction own house, as well as among firms in the field of construction. One way or another, the compositions for wood that are on domestic market are not inferior in quality to foreign products, but at a cost much cheaper than similar paints.
NEOMID exterior wood paint
Advantages:
- Very low price with pretty good quality.

Many years of experience and Finnish quality of this brand have long been known on Russian market. The company is a true specialist in the production of coloring compositions of a very wide range. Very strong and at the same time elastic film after drying. Since Finland is a northern country, the developers initially calculated and tested the compositions in conditions of severe frosts and severe precipitation, therefore this paint was initially perfectly adapted for Russia. Choice of 120 shades.
The compositions of this company show themselves perfectly on any wood surface. One of the key buying criteria for paint is its saturation. In the situation with this manufacturer, consumers receive the marginal coefficient of this criterion, which, moreover, meets 100% of the strict European standards.

Criterias of choice
To choose high-quality paint, experts advise to be based on the following characteristics:
- Manufacturer. It is better to choose trusted companies with an impeccable reputation. The compositions of two popular brands from Finland, which are in this rating, showed themselves well.
- Shelf life. This characteristic should be checked without fail, because after a while the paint loses its properties.
- Price. High cost is not always an indicator of quality, but you do not need to choose too cheap paints.
- Building specifics. It makes sense to take into account the characteristics of the material used for cladding in the case when the house was not built of wood.
- Preparation. For any composition there are specialized primers and impregnations.

The exterior design of the house should be approached as seriously as the interior. After all, the facade distinguishes the house from others, and is also an indicator of hospitality. There are a huge number of paints for the facade on the market, which differ in composition, properties and functional purpose. In this article, we will consider what paint to paint the facade, and how to choose the right paint for various types facade.
General concept of facade paint
The best paint for the facade has the following properties:
- resistance to temperature difference;
- resistance to ultraviolet radiation;
- water resistance;
- antiseptic properties;
- improvement of the decorative qualities of the facade surface;
- protection of the facade from chemical pollution.
The facade paints are based on synthetic resins, depending on this, acrylic, silicone or vinyl-based paints are distinguished.
The cost of paint is affected by the quantity and quality of binders and fillers.
Varieties of paints for the facade
1. Vinyl paints are losing popularity because of acrylic paints, as they have low vapor permeability and contain a large amount of water, do not have high resistance to chemical pollution, are not very durable and lose color over time.
2. Reactive facade paints consist of resins and hardeners. Such paint has a short shelf life. Therefore, the application of reactive paint is very fast.
3. Alkyd paints are composed of vegetable acid, alcohol and anhydride. Such paints are very elastic, but the higher the elasticity, the more time paint drying.
4. Acrylic paint has a high degree of protection facade walls from the sun, temperature changes and moisture. Such paints have a huge color scheme. Best for coloring concrete surfaces. They do not have high vapor permeability. There are three types of acrylic paints: water-based, solvent-based and latex acrylic paints.
5. Silicone - combine acrylic and silicate. Such paints are characterized by low water absorption. The level of vapor permeability of silicone paints is very low, and the degree of protection from the sun and temperature difference is high. They are resistant to mechanical stress. Silicone paints are produced in a diverse color palette.
6. Oil paints are losing popularity due to significant drawbacks. Oil paint takes a long time to dry. When applied to the surface, such paints are not very convenient. Over time, oil paints lose color and fade.
7. Acrylic-silicone - combine the properties of acrylic and silicone paints. They have a fairly high vapor permeability and low moisture absorption. Such paints have resistance to abrasion and self-cleaning properties.
8. Silicate paints the best way suitable for lime surfaces. Do not use this paint on gypsum or organic facades. The main binding element of silicate paint is liquid potassium glass, which has a high vapor permeability.
9. Polysilicon paints differ from silicone paints by the addition of acrylic resin. These paints are easier to work with, have high water resistance, and good vapor permeability.
10. Cement paints are produced in dry form. As a thinner for cement paints, water or special preparations are used. Such paints have high vapor permeability, but are very susceptible to moisture, which leads to the formation of streaks and stains.
11. Lime paints are produced in pasty form. The paste is diluted with water and dyes. Such paints have a high level of water absorption and do not protect the building from moisture and dirt. Lime paints have good antiseptic properties and protect walls from fungus and mold, and also have high vapor permeability.
12. Textured paints will give the facade originality and uniqueness. When applying such paint, a thick layer is formed. polymer film, which has a specific texture. Textured paints are quite resistant and durable.
1. The composition of the paint should contain a large amount of binders that ensure the adhesion of the paint to the facade.
2. Choose a paint with a minimum amount of fillers that do not affect beneficial features paints, but significantly increase the volume.
3. Find out information about the absorption coefficient of facade paint. The lower the water absorption of the paint, the more reliable protection houses from water, mold, fungi and even cracks. The best option is 50 g / m².
4. Pay attention to UV resistance. Under the influence of sunlight, the paint burns out and loses its presentable appearance. In this case, preference should be given to acrylic, acrylic-silicone or polykremlin facade paint.
5. As part of the paint, determine the vapor permeability. The optimal value of the vapor permeability coefficient is 120 g/m² per day.
6. Abrasion resistance is another important point when choosing paint for the facade. This value is measured in cycles. Exterior paint with a wear rate of 5000 cycles is a great option.
7. Exterior paint consumption is calculated by multiplying the area of the territory to be painted by the paint consumption specified in the instructions. Average consumption facade paint is 9 l/m².
8. When choosing the color of the facade, consider the color of the roof, windows, doors, stairs or porch. All this should be harmoniously combined.
9. If the house is located in the sun, it is better to choose a matte surface, as a glossy one will shine a lot. For a house located in the shade, a glossy sheen of facade paint is perfect.
10. In order to correctly evaluate the color of the paint, you need to go outside with the paint and see how the paint looks in the sun.
11. When in doubt about the choice of color, it is better to buy one can of paint, and try painting less accessible walls.
12. When calculating the amount of paint, it is better to use a special program that will accurately determine the amount and type of paint.
13. For right choice colors pay attention to neighboring houses and environment in order to maintain the overall color gamut.
15. Light colors will make the building bigger and brighter. White color Perfectly harmonizes with the dark roof.
16. For warm regions, it is preferable to choose bright hues in home painting that will repel heat. In the north or in colder climates, dark and warm colors are suitable, which attract heat and provide additional heating to the room.
Facade options:
- a good option is to combine shades of the same color used in the decoration of the roof and facade;
- better use natural colors in wall decoration;
- the variety of colors negatively affects the appearance of the house, the maximum number of colors is three, four;
- if the roof is bright color, in the decoration of the facade, use calm shades;
- using only one color to decorate the entire house is a bad option.
A variety of paint bases for the facade
The quality of the base for paint also has great importance. Based on the quality, choose the appropriate type of paint.
For a facade with a cement-lime or cement-plaster base, the most the best option will be vinyl, acrylic, silicone, polysilicon or cement paint.
For silicate plaster silicate, polysilicon, cement or lime paints are suitable.
All types of paints are suitable for lime coating, except for silicone, which do not pass carbon dioxide well.
The best option for an organic plaster surface would be acrylic, silicone or polysilicon paint.
For painting concrete surfaces, paints with a high content of acrylic are most often used.
For walls made of ceramic bricks, all paints are suitable, except for polykremlin and silicate. These paints are suitable for walls made of silicate bricks.
For a metal facade, paints that have good anti-corrosion properties are suitable.
Paint for the facade of a wooden house: acrylic-based primer, acrylic or alkyd enamel, colorless varnishes.

How to paint the facade
1. Remove old paint, replace damaged parts.
2. Repair the surface and repair small cracks.
3. Dry the surface well and apply two coats of primer.
4. Swipe final alignment and prime the facade again to increase the adhesion between the paint and the wall.
Start painting the facade from the corners and hard-to-reach places. The last thing to paint is the basement of the building. Apply at least two coats of paint. The time between applying layers is two, three hours, depending on the type of paint.
Plaster surfaces are painted at least two weeks after plastering. Paint for wooden facades is applied after the wood has been treated with an antiseptic and a fireproof solution.
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 subject to alkaline corrosion - degradation of the binder, which causes discoloration and even destruction 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 paints are currently used (from sunflower oil), combined (using volatile solvents), oxidized (“oxol”) and artificial (also solvent-containing) drying oils, 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. For facade works two types of these materials are most suitable: 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 included in their composition are dispersed in the form of tiny particles in water, and are not 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 bred on the water and combine best properties Acrylic and silicate paints: their vapor permeability is almost as high as that of silicate paints (therefore, they are also suitable for buildings with poor waterproofing of foundations), and in addition they do not support the development of microorganisms. Silicone resin, which is a binder, after drying the paint looks like 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 protection from UV rays. Very resistant to oxidizing agents contained in atmospheric air while maintaining 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.
The appearance of the facade of the building significantly affects its perception. The easiest way to give a new look to an old house or complete a new building is to paint the facade. High-quality paint plays not only a decorative role, it protects the wall treated with it from external influences. Facade paints are made just for exterior cladding, so you can be sure of their durability and resistance.
The shade of the dye plays significant role in the exterior of the building. It is equally important that it be evenly applied to the surface. The choice of composition according to the degree of gloss - matte or glossy - also matters.
Now on sale there are compositions for facades of a wide variety of colors. In addition, they differ from each other in terms of service life and the type of surface on which they can be applied. However, from the point of view of chemistry, they are not much different, so both have the same components:
- a binder component called the base;
- coloring pigment;
- mineral type additives, other fillers.
Among the huge variety of facade paints, the main ones can be distinguished:
- silicate,
- made on the basis of potash glass,
- silicone, including varieties such as:
- silicone-acrylic
- silicone emulsion,
- calcareous (mineral),
- latex,
- polysilicon.
Almost all paints for facades are sold in PVC buckets, which is very convenient. In many cases they are suitable for use immediately, sometimes you have to dilute them a little. The consistency of the paint can be changed and, depending on the layer, make it thicker or more liquid.
Facade dyes according to the type of material being painted can be used for:
- plastic,
- tree,
- metal,
- brick,
- concrete,
According to the composition of the components, as well as the type of solvent, these paint and varnish coatings also have a classification. For example, water-soluble formulations can be water-dispersed (with the addition of a polymer) or mineral.
Dyes, which are based on organic solvents, are diluted with volatile chemical compounds, for example, white spirit or xylene. They have a number of advantages, for example, they can be applied even when high humidity and at temperatures below zero. However, there are also serious disadvantages, such as toxicity and flammability. When working with this type of paint and varnish products, you must be careful and observe safety precautions.
Coloring compositions for water based have a number of positive features. They are the safest and most environmentally friendly, despite the fact that binders, color are added to them, and synthetic type fillers are present. These compounds are non-toxic and non-flammable, which is ideal for facades. wooden type. They resist moisture and are very durable. Such paint can be safely applied in several layers. However, there is no escape from the shortcomings. In frost, water-based compounds behave poorly and harden already at zero temperature.
There are also textured paints made for facades by Tikkurila. They form a resistant film on the surface to be coated and, due to their special structure, significantly change the appearance of the building.
There are several other popular types of paints, for example, oil or alkyd. They are intended for outdoor work, but are not suitable for processing facades.
There are paints for outdoor work on metal or special ones, for MDF facades but they are much less frequently used. To work with them, you must first cover the surface with a specialized primer, which is not very convenient and time-consuming.
When buying facade paint, you should not first of all pay attention to color. First of all, it should suit you according to the type of surface to be treated and the purpose. With the help of the catalog, you can easily select the desired shade. Take the choice of dye seriously, as choosing it correctly, you can enjoy the new look of the house for 10-20 years, in accordance with the expiration date.
Table. The choice of facade paint.
| Facade surface material | Type of facade paint |
|---|---|
| Cement and cement-lime plasters | Cement, lime, acrylic, vinyl, silicone, siloxane, acrylic silicone, silicate (polysilicon) |
| silicate plasters | Silicate (polysilicon), lime, cement. After priming, you can use vinyl, acrylic, silicone, siloxane, acrylic silicone |
| Lime plasters | Lime, cement, silicate (polysilicon), silicone (high carbon dioxide permeability). |
| Concrete | Cement, acrylic, silicone, siloxane, silicate (polysilicon) |
| ceramic brick | Acrylic, silicone, siloxane, acrylic-silicone, silicate, lime, cement |
| silicate brick | Silicate (polysilicon), cement |
Characteristics of facade paints
Today, it is especially popular latex paint. Its main advantages are ease of use and versatility. This dye remarkably fights with external influences, does not suffer from temperature extremes and precipitation. The facade, covered with latex paint, does not require special care. Most of the time it doesn't even need to be wiped down. But this dye, like any other, has its drawbacks. For silicate and lime walls it doesn't fit at all. But with concrete and reinforced concrete products, latex paint is combined perfectly.
Silicone acrylic paints
Silicone-acrylic paint has absorbed the advantages of both emulsions of which it consists. This composition is almost universal and can be used on almost all surfaces. Also, this coating is durable and does not require special operating conditions.
Silicone emulsion paints
Silicone emulsion paints also have a number of distinctive features. First of all, it is high vapor permeability. This feature allows you to use paint not only outside the building, but also inside, even if the waterproofing of the foundation leaves much to be desired. Fungi, mold and microorganisms do not develop on such a coating. Connecting element These dyes are formulated with a silicone resin that can form a matt, dense film, making them ideal for wet areas.
mineral paints
Mineral paints contain cement, lime is present, which is very environmentally friendly. In addition, this significantly reduces the cost of this paintwork. Mineral paints can be applied to most surfaces on the outside of a building. They are wonderful at taking in and evaporating water, but suffer from constant rain. It is best to cover brick or concrete with mineral paint, having previously plastered it. with wooden and metal surfaces it is completely incompatible.
Silicate facade paints mostly consist of liquid silicate glass and organic additives. They do not repel water very well, but they have excellent vapor permeability. This type of paint is strong enough, it does not fade in the sun, although after a while it begins to fade. On a pre-prepared surface, it lays down perfectly. Subsequently, it does not suffer from pollution. Primarily, silicate paints were created for application to limestone building blocks.
Silicone modified paints
home distinguishing feature silicone-modified paints - excellent adhesion. They are popular due to their high vapor permeability and UV resistance. They protect the material on which they are applied. With this paint, your facade is not afraid Sun rays and precipitation. It will not lose color, will not begin to collapse, and will not even be covered with microcracks. Due to the ability to keep the surface intact, silicone-modified paints are used for buildings, buildings or problem areas. They enjoy special respect among restorers.
Polysilicon paints
Polysilicon, or, as it is otherwise called, silicate-ash facade paint is a modification of the silicate coating. Its price is much higher than that of other types of paint, but this is justified by the improved characteristics. However, she has one drawback. It's not the most pleasant smell. After painting, it quickly disappears, and when the coating dries, there is not a trace left of it.
When choosing a facade paint, you should pay attention to several factors. But the main one is the compatibility of the selected paintwork with the surface on which it is to be applied.
Dispersion paints
Even for outdoor work, dispersion paint is often used, but it should not be used for facades. She reacts capriciously to weather conditions and is suitable only for covered verandas. Main enemy such paint - humidity. Because of it, not only mold, but even moss can start on the surface.
For facades with complex design, consisting of metal, wood, gypsum, concrete goods and other materials, universal dyes are best suited. To use them, you first need to cover the surface with a specialized type of primer. If necessary, you can mix paints of different composition, but one shade.
Application of facade dyes on different types of surfaces
Very rarely, facade paint can be applied to the surface immediately, without preparation.
You almost always need to do a number of things before doing this, namely:
- clean the surface of the old paint, dirt and dust;
- strengthen the surface layer, if necessary;
- repair cracks, if any;
- plaster (depending on the surface, this may not be necessary);
- cover the surface with a primer;
- paint.
For painting, there are many devices, as a rule, the instructions say which one to use. You may need a roller or a wide brush, spray gun or a special machine for painting.

- All attachments must be checked before use, they must be fully functional, and their parts must be intact.
- Before work, it is required to wear overalls and gloves, to protect the head, eyes and Airways. Shoes must not slip. It is desirable that its sole was thicker.
- When painting a one-story building, a stepladder is required, and for multi-story buildings, you need to use mounting equipment and insurance. It is important to take into account the weather conditions - it is strictly forbidden to work in strong winds.
