Preparing the house for painting facade paint. Painting facades mdf. Painting the house with textured paints

Reading time ≈ 3 minutes

Works related to the external painting of the house perform an aesthetic and protective function. High-quality painting of the facade of a private house can change the appearance of the building, give it a stylish and modern look. And on the other hand, it is the facade that takes the blow external environment: moisture, wind, rain and snow. In principle, painting the facade of a building is not much more difficult than painting the walls from the inside. Just required special paint for external work, a slightly different preparation of the base and installation of scaffolding.

scaffolding installation

Particular attention should be paid to the installation of scaffolding. They can be rented and gradually rearranged from wall to wall or made independently. Mobile scaffolding is quite convenient.

Scaffolding must be stable - this is a guarantee of the safety of the work being carried out. If the house is one-story, instead of scaffolding, you can use the so-called. scaffolding or do without them altogether, and paint with a roller on a high handle. However, in this case there is a risk of poorly painting over the upper parts of the facade.

Preparatory work

Before starting work, the base is dedusted and cleaned. Cracks, chips, pits, depressions are plastered.

The base must be primed depending on the material: primer or impregnation to improve adhesion and to reduce the consumption of painting material.

The primer can be applied with a brush, roller or spray gun.

Do-it-yourself facade painting

Facade paint, as a rule, is distinguished by high weather resistance, wear resistance, and resistance to ultraviolet rays. Famous manufacturers of paint and varnish products, entire systems for cleaning, priming and painting facades have been developed. It is better and more convenient for work to select a primer and paint from the same manufacturer. Universal option for any bases - acrylic paints. They also carry out painting of the facade on plaster.

Facade wall painting technology

Before carrying out work, the paint must be opened and thoroughly mixed until smooth. First you need to paint around the perimeter of door and window openings, complex architectural areas.

Such staining is more convenient to produce with a brush.

Flat large surfaces are more convenient to paint with a soft roller.

Painting the facade with a roller is done from top to bottom. Don't Forget the Funds personal protection. It is necessary to work with gloves, if staining is done with paint with a pungent odor, you need to wear a respirator.

Depending on the quality of the paint and the degree of porosity of the surface, it may be necessary to apply several layers of paint, each of which is applied only after the previous one has completely dried.

At the end, very carefully with a flat brush, paint window slopes. They are usually dyed White color, because it reflects the color of the sun and makes the rooms much lighter and brighter. However, you can choose a different window frame, depending on the architectural concept of the style.

Quality exterior finish houses are visually determined only by assessing the level of wall painting.

It does not matter whether a complete layer-by-layer processing was carried out, the whole complex of works was done from scratch, or only cosmetic painting of the walls was done - outwardly everything looks exactly the same and for most means the same thing - repairs have been made.

This is the main property of facade paint - the creation of a decorative outer layer that makes the appearance of the building new and elegant. Sometimes a simple repainting of the walls in a different color looks like a complete change in the appearance of the house, affecting all elements of the architecture, although there were no constructive additions or other interventions.

At the same time, painting the walls of a summer residence affects much more important operational issues, not limited to external effects. In this article we will talk about how to color a private house with your own hands (+ photo) and how to properly care for the surface.

Facade painting - this is the application of an external decorative and protective layer of the outer coating. In addition to purely visual changes, the ink layer creates a strong protective film, cutting off the material of the wall from the penetration of water from outside, from temperature influences, excludes the appearance of mold, fungus or algae.

Besides, an important ability of facade coatings is vapor permeability, i.e. the ability to remove moisture from the inside at the capillary level without the possibility of absorption from the outside.

Paints that do not have high vapor permeability are unsuitable for outdoor use, since the steam, which does not have an outlet to the outside, begins to accumulate inside the walls, causes them to get wet, eventually the moisture freezes, expands and tears the walls apart from the inside.

Therefore, very important point, the durability of the service life of materials and structures depends on it, the possibility correct operation wall cake, and only in the last place - the decorative qualities of the finish.

Types of facade paints

Facade paints have approximately the same structural composition:

• Base (film former).
• Fillers.
• Pigments.
• Solvent.

According to the type of base paint are:

• Mineral. The basis - derivatives of cement and lime, are inexpensive materials.
• . Produced on the basis of liquid glass with additives. They have low water repellency.
• . Expensive paints based on silicone resins. They have an excellent set of properties - high vapor permeability, completely impervious to water, very elastic. The reason for the rare use is the high cost of the material.
• . One of the most common paint groups, has good qualities and relatively low price.

Solvent type:

• On organic solvents (white spirit, etc.).

The choice of one or another type of paint is determined by the material of the walls and the features of operation, climatic and weather conditions of the region.

Water based paints

— emulsion of fine particles of the working mixture in water. When applied, water is partially absorbed into the base, partially evaporates, leaving a coating film, which, after drying, does not react at all to water.

T which composition has important advantages:

• No smell. This is the main advantage of materials on water based, which often determines the choice of users.
• No strong shine. The surface has either a deep matte finish or a soft silky sheen. Visually matte planes look more even, do not glare and create a noble and stylish look of a house or cottage.
• The presence of excellent working qualities of the coating. Almost all water-dispersed paints have a complete set of properties that allow them to successfully perform their functions.
• Can be tinted to any color. All water-based formulations are available in the form of two or three types - bases. Usually the first one is white and can be used as self paint or tinted in some light shade. The second and third are transparent, intended for tinting into denser and brighter colors.
• Low consumption. Most water-based formulations have high hiding power and low (relatively) density, allowing coverage large area than other types of paints.
• Fast drying. Unlike other types, water mixtures dry within a few hours, allowing you to work as quickly as possible.
• The diluent used is ordinary water, which greatly facilitates (and reduces the cost of) the work, helps to keep the working tool in order and clean.

The disadvantages of water-based paints are:

• Contraindications for use on metal substrates.
• Weather restrictions, do not apply in rainy weather.
• The spots that appear are poorly erased, and repeated washing of the walls spoils the appearance of the coating.

The disadvantages of water-dispersed facade paints are not critical, the popularity of such compositions is steadily growing.

Organic paints

Organic based materials are more traditional as they have been in use for a long time. Many users prefer them for this very reason, not trusting the apparent fragility of water formulations.

Organic-based paints have a lot of advantages:

• Coating strength.
• Elasticity, the ability to compensate for minor movements during shrinkage.
• Water resistance.
• Frost resistance.
• Vapor permeability.
• Compatible with most surfaces excellent adhesion to metals.
• Tolerance of sharp temperature fluctuations.
• Durability.
• Possibility of painting low temperatures or high humidity.

The disadvantages include:

• Strong smell upon application and some time after drying.
• It takes one coat to dry long time- two days, for the subsequent drying time increases.
• The need to use solvents, which increases costs.

Paints based on organic solvents have a strong gloss. This property causes a different attitude - for some it is highly desirable, others consider it a disadvantage.

NOTE!

Besides, a significant drawback of paints on organic solvents is a strong smell, which is very poorly tolerated and can cause feeling unwell some people.

This circumstance reduces the competitiveness of such paints compared to water-based ones, although the other qualities of the material are quite successful and allow you to create a durable and durable coating.

How to choose facade paint for a certain surface?

• First of all, for right choice outer coating should take into account the base material. Most facade coatings have a specialization (including after), and of various composition. At the same time, water-based paints are not always suitable for and are completely unsuitable for application to metal (steel) bases, which is the main difference from paints based on organic solvents, which serve as reliable protection for such bases.
• The second selection factor is the quality of the surface. The presence of gloss, the color of the walls directly depend on the composition of the paint used for exterior finish. Water mixtures have more bright hues and a predominantly matte surface, while organic-based materials allow hard gloss coatings in dense tones, and the choice of color and its tonality is much wider than with water-based paints.
• Wherein, Don't forget about building conditions.- in areas with a high level of atmospheric pollution by various industrial or other substances, dustiness or the presence of a large amount of exhaust gases (industrial or close to large highways) paints with high water repellency should be used, allowing you to painlessly endure periodic cleaning of the walls. For regions with frequent rains, this choice is also relevant, since the penetration of rainwater into the material of the walls threatens to destroy them.

What facade paint is the best?

The optimally selected material should correspond as much as possible to all existing conditions - operational, climatic. In addition, the decorative qualities of the coating are important, since they are the first to be evaluated when looking at a freshly painted house.

Recently, user preferences are increasingly given to water-dispersed compositions., which can be explained by their properties. The most important of these is the lack of odor.

Also important is the ability to remove paint stains with ordinary water - an important plus, since solvents can also remove the necessary substances, which will lead to damage to objects accidentally stained with paint.

Preparing the wall surface for painting

Painting requires a clean, dry wall surface.

For preparation you will need:

• Detach All hinged structures - brackets, awnings, lights, air conditioners, etc.
• Remove trim from windows or doorways.
• Inspect the walls, determine the degree of wear of plaster or other materials.
• Detected flaws are puttied, with large quantities peeling or shedding, it is recommended to apply a leveling plaster layer.
• Some types of facade paints require preliminary priming.

Facade painting technology

Painting work is carried out in dry calm weather.

The air temperature should be:

• For water-based paints — from +5° to +30°.
• For compositions on organic solvents, the temperature range expands downwards (there are brands of paints that can be used up to -20 °), but due to the strong smell, application in hot weather is difficult.

The paint is applied either mechanically — spray gun, air or airless spray, or manually using a roller or brushes.

Before applying paint, be sure to carefully read the method of application and additional terms work to avoid potential errors.

Depending on the type of paint, the entire surface must be covered at one time (in general, such conditions apply to water-based coatings, since the joints different layers they are very noticeable), or interruptions in work are possible (paints on organic solvents).

Most often, the surface is painted in two layers, the interval between applying the second layer of paint is usually 16-24 hours.

Facade maintenance is minimal. No action is required other than occasional hosing with water to remove dust.

Applying any protective compounds or other actions aimed at improving the condition of the coating is not applied, since the quality and properties of the coating fully comply with all requirements and do not need additional measures.

Facade paints, with all the breadth of the range and variety of types, perform the same task. Since they are created specifically for this purpose, the difference in properties is not critical and consists only in some positions.

Water-based paints and materials based on organic solvents are able to fully satisfy all requests and provide high-quality protection of walls from external destructive factors, as well as decorate the house and create a stylish and neat appearance.

In contact with

The painting of the facade is done in a certain sequence. In doing so, all necessary processes, including and careful preparation walls. The work does not require special high qualifications, so the facade of the house can be painted with your own hands.
The most difficult issue is the choice of facade paint. It is desirable to entrust its decision to specialists. It is necessary to correctly choose the main color of the facade, the combination of accent and decor colors, as well as determine other necessary properties of the facade paint.

The main stages of work on painting the facade

• The condition of the walls of the house, the methods of their preparation are determined. Removal of delaminations, dedusting, leveling of a surface is carried out.
• The walls of the house are primed.
• All structures that should not get paint - openings, glass, attachments, plinth, blind area, roof overhang, gutters, gas pipes ..., - are protected with polyethylene, pasted over with masking tape. The boundaries of the application of paint are determined by pasted adhesive tape.
• Facade paint is usually applied in two layers. The first layer must dry for the time specified by the manufacturer, after which the second layer is applied.

Important notes on facade painting

• One layer of paint on one wall is applied in one day without long breaks. If you take a break, then the border of applying paint will remain noticeable.
• Ensures the safety of working at heights. Be sure to erect scaffolding, wide scaffolding. Painting from a stepladder is not convenient, it is dangerous.

Choice of time and weather

Before painting the facade, you need to familiarize yourself with the weather forecast. Work is performed if:
- no rain, the wall of the house is not soaked;
— there is no strong wind, dust is not applied, the paint layer is not blown off;
- air temperature is +5 degrees and higher, but for faster and better drying and better adhesion, a temperature of more than +10 degrees is desirable. WITH.

Checking the condition of the wall and preparing it for painting

Do not apply paint to the facade until it is dry, firmly-dense and primed.

Walls for painting can be old and new, their preparation varies significantly.

Old walls must be cleaned of all fragile layers, and their surface leveled. There can be quite a lot of work here.
More often than not, the workflow is like this.

• The wall is washed from dust from the hose using a stiff brush, separating loose plaster along the way.
• Potholes, cracking plaster close up durable plaster composition, level the surface.
• After the solution has dried, the wall is primed abundantly, the primer is allowed to dry for at least a day.

But other options are possible. If the facade has old paint, then you need to check its strength. Scotch tape is glued onto the old paint and jerked off. If the paint comes off with the tape, then it needs to be removed. If not, then you can paint over it again. For removing old paint a sandblaster is required from the wall.

Also on old wall possible growth of mold and moss. Such surfaces are carefully cleaned with a spatula, after which they must be treated with a bioprotective compound, otherwise re-growth will occur through the new paint.



New walls are usually level and free of dust. But they have a lot of building moisture. It is not recommended to prime and paint new walls earlier than 2 months after the completion of other wet building processes on the walls (masonry, plasters, including inside). For normal drying of the walls, it is necessary to provide high-quality ventilation inside the building.

Facade paint paints not only plastered surfaces, but also masonry without plaster from ordinary (not clinker and front) ceramic and silicate brick, from aerated concrete blocks.
It is possible to use paints that hide small cracks and even chips.
Important to choose suitable paint to this façade.
The question of choosing a paint is complicated, it is advisable to get the recommendations of a specialist in selecting colors for the facade -, - read on the topic.



Wall primer

The primer of the walls before painting is mandatory, it allows you to compact and strengthen the base, close the pores in it, reduce the absorption of liquid, and greatly reduce paint consumption.

Experienced finishers paint the primer in a color close to the paint, which helps to obtain a more stable and deeper color of the entire facade.
The primer is applied with a roller or brush. After that, the wall is allowed to dry before painting for at least a day.

One acceptable primer is 1/1 water-thinned paint.



What and how paint is applied to the facade

The use of an airbrush is the lot of professionals, since there are many nuances in the preparation and management of this tool. With the help of a brush or roller with your own hands, you can paint the facade just as well.


• On flat smooth surfaces it is more advisable to use a roller - the work will go faster, and the paint layer will be more even.
• For textured, rough surfaces, for brick it is more expedient to use a wide brush with a long pile.
• Paints that they create textured surface, viscous with a granular filler, are applied with a spatula, like plaster.

When applying, it is important to distribute the paint evenly over the facade - it is applied in alternating movements in different directions, - vertically, horizontally and diagonally.



How much facade paint do you need

Paint consumption is directly related to the condition of the facade.
Smooth and primed wall surfaces require the least amount of paint. And rough, fissured, porous - 2 - 3 times more.

In accordance with this, manufacturers normalize paint consumption with a spread of values ​​\u200b\u200bby 2–3 times, for example, it is indicated that paint consumption for a facade is 0.1–0.25 liters per square meter of surface.

It is not difficult to calculate on your own how much paint is needed for exterior wall painting, if you know its specific consumption.
It is necessary to multiply the area to be painted by the estimated consumption, and then multiply by the number of layers (2 layers are applied). It is advisable to take another 10% of the stock so that it is not enough.

How paint is stored

Facade paints during storage deteriorate rapidly if not observed temperature regime. Paint during storage should not be frozen and should not be heated under the sun. Typically, manufacturers recommend a temperature for storing paint - +5 - +25 degrees.
If you put the paint in storage immediately in the appropriate place, then it will be stored reliably.
Even if the expiration date has passed, then the paint that has been stored normally, as a rule, remains usable. It remains only to stir it with a mixer, since most paints delaminate.

Building a house is always finished finishing work along the facade.

One of the options to carry out such work is its painting, which is done after plastering the walls.

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

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

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

Performance characteristics

For immediate stamina paintwork answers this characteristic.

In this dependence, materials are divided into two types:

• weatherproof;
• limited stability.

Only the first option is suitable for painting the facade, because only with its help it is possible to achieve the desired result regarding the protection of the surface of the house.

Weatherproof paints are characterized by vapor permeability for walls that are treated with plaster. Due to this property, after the appearance of condensate on the surface of the facade, it evaporates after a while and does not accumulate under the coating. After all, the accumulation of condensate promises the appearance of bulges on the walls and further 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 in the composition of the paintwork.

In addition to vapor permeability, a very important indicator - resistance to UV rays, which most of all subject the layer to destruction. In addition, the resistance to sunlight ensures long-term preservation of the color and the appearance of the paint is always as freshly applied.

Facade painting

Do not neglect the adhesion characteristic, it provides reliable bonding of the paint structure and plaster on the facade. If the paint has a high adhesion index, then it is able to prevent the appearance of blisters and bulges. However, not only the properties of the material itself provide good adhesion, but also the correct process of preparing the surface of the walls 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 soaking into the surface of the wall.

Last operational 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 carrying paintwork is an important factor V this process . The technology of painting the facade on plaster requires the thinnest possible layer when applying the material.

This is due to the fact that a thick layer of paint is chipped off very quickly.

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

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

NOTE!

Given that all the protective properties of paint coatings acquire after complete drying, it should have high speed drying out. This property allows painting under any weather conditions, even in the late autumn period.

decorative characteristics

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

Properly selected paint should not change its color when applied, as well as after some time.

Regarding the texture of paints, they are:

• matte;
• glossy;
• semi-gloss.

Variety of colors

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

Is coloring necessary?

Many people wonder about the need to paint the plastered surface. You can answer this question if you consider in more detail the benefits that such an event provides.

The first and most important property that facade painting provides is a protective function.

Plaster is a rather vulnerable coating that is capable of passing moisture and accumulating condensate, is destroyed by mechanical stress or after prolonged exposure to sunlight.

If mechanical damage or any other destruction is quite simply restored, then the lack of such properties as transmissibility and water repellency can cause significant damage to the walls of the house. The accumulation of condensate provokes not only the formation of mold and fungus, but also the destruction and decay of materials that are in the "pie" of the wall.

If paint is applied to the surface of the facade, corresponding to a high level of these characteristics, then many problems can be avoided. An added advantage application of paint is the possibility of creating 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 decoration:

1. Silicate. The paint is based on liquid glass, which otherwise called silicate glue, as well as various mineral pigments and silicate type filler. Such a composition is able to provide durability, complete resistance to precipitation, even acid type and is by far the best option. On average, this type of paint can last more than 20 years. It 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 the thermal expansion of the plastered surface, traces remain on the paint.
2. Lime. For the basis of the production of this type of paint used slaked lime . Such paint is washed off by precipitation and gets very dirty. Its merits include high level vapor permeability and resistance to the appearance of fungus. With regards to the variety of colors to choose from, it is very limited and is represented only by pastel colors.
3. cement. The cement variety of paint has all the features inherent in the lime variety, but have more high level of resistance to moisture and precipitation. In addition, it does not have a bactericidal effect, which allows the formation of fungi.
4. Acrylic. The basis of the composition of this type of paint are acrylic resins. It has a sufficient level of vapor permeability, but it is significantly lower than that of the silicate variety. She is characterized low hygroscopicity but high abrasion resistance.
5. Silicone. This type of paintwork is considered the most worthy option for painting a plastered facade. Thanks to it, the facade acquires hydrophobic properties., any precipitation and condensate flow down the walls without accumulating on the surface. Silicone variety provides free diffusion. Adheres well to any type of surface, resistant to prolonged exposure to sunlight and various adverse weather conditions. The paint surface is incapable of electrifying, which ensures the repulsion of dust and the surface of the facade does not get dirty so quickly.

Specifications

Choose the most suitable option it is possible, taking into account all the nuances in the aggregate, with regards to 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, a silicone type of paint is considered the most suitable, because. it provides complete protection against negative impacts and looks aesthetically pleasing.

Wall preparation stage

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

First of all, intending to paint the facade, it is necessary to choose the right weather . You should choose a day in which rain, strong winds or temperatures below + 5 degrees are not predicted.

The wall preparation process is as follows:

1. First you need to remove the layer of paint, which is present on the facade (in case 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 building hair dryer and a hard spatula. If an acrylic variety was used, then it is allowed to apply acrylic water-based paint on top.
2. Next, it is necessary to assess the condition of the plastered surface. The wall, which is ready for further painting, must be leveled, while not getting dirty, not leaving dust on the hands and not crumbling when in contact with it. It is recommended, in the absence of the above criteria, to putty the facade.
3. Primer application is a good way to give strength to the plastered surface and increase the degree of adhesion of the paint and the wall. The soil for such work is selected penetrating type.

Facade cleaning

Wall priming

Facade painting technology

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

The painting process is as follows (photo below):

1. First of all, the paint is thoroughly mixed with a mixer.
2. The most convenient way to apply paint is with a spray gun. However, if such equipment is not available and a brush or roller is used for staining, then the application of paint is carried out with strokes. It is recommended to apply strokes in different ways: in the vertical direction, horizontally and diagonally. Despite such a peculiar method of staining, it is able to provide the maximum degree of uniformity of the future coating.
3. All types of paints for the facade need a two-layer application. The lime variety is applied in 3 layers.
4. The staining process should not have too long pauses. The paint, after it begins to dry, further creates a visible border between the part of the wall that was painted earlier and, accordingly, later.
5. Application of layers should be carried out only after the previous one is completely dry.
6. After painting, the walls are protected from dust particles and precipitation. To do this, cover them with plastic wrap.

Conclusion

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

In addition to the need to obtain a durable coating that creates protection for the facade, it is very important to carry out the whole process in such a way that the facade also looks attractive.

In contact with

The easiest way to update external walls at home and make them unique is coloring. To do this, you do not even need to hire a professional team, but you can do it yourself.

But here many people have a question, the facade of the house with their own hands? To do this, it is enough to have the necessary equipment, suitable paint (according to the material from which the walls are made) and a small amount of knowledge. And now about everything in order.

In order to qualitatively paint the facade, the following devices are needed:

• brushes different sizes or rollers;
• trough for paint;
• spray gun;
• primer;
• a film with which you need to protect places that are not subject to staining;
• ladder or scaffolding;
• desirable protective clothing and glasses.

Brushes are suitable for painting small details or making a rosary and a beautiful outline. Large-scale painting of the facade of the house with your own hands is faster and better done using a roller or spray gun.

Clothing and goggles will protect against the ingress of coloring solutions on skin or mucous membranes. The film should be well covered with those places where it is not necessary to paint. During the process, material may run or drip from the tool.

We select the coloring material

When choosing a facade paint, you need to remember that poor-quality material will not fit well on the base and after a while you will have to redo everything. Therefore, there are several criteria that such a finishing material for facade:

1. Resistance to sunbeams, high humidity.
2. A high level of vapor permeability, this will allow the walls to breathe and not accumulate moisture inside the house.
3. Good elasticity, helps the layer to stretch if the base is under impact high temperature expands.

In addition to these criteria, one should also pay attention to what the walls of the house are built from. In order for the paint to hold well and for a long time, it must be suitable for this particular material.

Water-based material is well suited for walls made of brick or finished with plaster. This is the most a budget option. But it will not last long, in a couple of years the coating needs to be updated. The oil version is good to lay down on a wooden and plastered surface. Such a surface can last up to 10 years.

If the question arises what paint to paint the concrete facade? Then here great option alkyd materials. They adhere well to the surface and resist negative factors.

Most a good option- These are acrylic paints with synthetic resin components. You can paint any surface without fear. The applied layer will be elastic and last up to 7 years.

How to calculate the amount of materials

If you are painting the facade with your own hands, then you will have to calculate how much paint you need yourself. Should be counted total area walls that you plan to paint, subtracting window and door openings. With these data we go to the store and select the desired composition.

We carefully study the jar or packaging and find figures that show the consumption of paint per 1 m2. After that, we multiply the area of ​​\u200b\u200bthe walls by the amount indicated on the container and get the result. Do not forget that any paint must be applied in 2 or even 3 layers. This will make the coating thicker and more durable. Therefore, the resulting figure must be multiplied by 2 or three.

To speed up the purchase process with your data, you can contact a consultant.

Preparatory stage

Regardless of what material the carriers are made of, for quality coverage facade paint the base must be well prepared.

1. You need to remove the old layer, if there was one.
2. All contaminants must be removed greasy spots, traces of mold or fungi.
3. All holes and cracks are carefully sealed.
4. Irregularities are polished.
5. The prepared surface is covered with a deep penetration primer.

Only after the primer is completely dry can you begin to apply facade paint to the walls of the house.

brick facade

By applying several layers on a brick, you can easily hide minor defects. But it must be remembered that Brick wall in its original form will last much longer than painted. As mentioned earlier, after a few years the paint needs to be applied again.

Therefore, if there is Alternative option, then it is better to resort to them. But if this is not found, this is also a good option. Apply from the top of the wall using a wide brush. In order to reach the highest points, you should build scaffolding or use a ladder.

The width of the brush should match the width of the brick. A thinner brush should be used for masonry joints, they can be highlighted with a more contrasting paint, thus preserving the pattern of a brick wall.

It is better to apply paint on a brick in two or three layers to make a strong barrier against moisture penetration from the external environment. The seams should be processed after the base layer has completely dried.

plastered walls

Most often in order to prepare the facades of houses.

This helps to insulate and level the walls, making the surface smooth. The paint will adhere well to the plaster if the following rules are followed:

1. Do not start painting on damp surfaces. The applied and sanded layer of plaster should dry completely for 4-5 days.
2. After that, you need to apply several layers of primer, which in turn must also dry. The packaging says exact time complete drying.
3. Now you can apply paint. For a plastered surface, a roller is used. Having dipped the roller into the paint, and its excess is squeezed out on the corrugated surface of the paint trough. You need to move it in different directions (horizontally, vertically, at an angle) so that the paint lays evenly and there are no bald spots.

The coloring composition is applied in several layers, allowing each of them to dry thoroughly.

wooden facade

Owners of wooden buildings often wonder how to properly paint the facade of the house so that the paint lasts as long as possible? There are some nuances here, missing which the result will not be the same.

Coloring wooden walls you have to start with sanding. To do this, use a special machine that removes the old layer of paint or varnish, as well as a small layer of wood, approximately 1mm. This is necessary so that the painted walls have an updated look much longer.

The old finish may swell under the influence of the substances that make up the new dye. Thus, the new coating will also lose its presentable appearance. After sanding, the wood should be coated with a primer solution with antifungal components. Once the primer is dry, you can start painting.

It all starts at the top of the wall. At the joints, it is better to use a beveled brush, it will process the recesses well. A wide brush is suitable for the main surface. When the paint begins to soak, do not apply it with an additional layer in separate areas.

It is better to wait until the first layer dries well and then apply another one to the entire surface. Then the layer will be as uniform and attractive as possible.

Some nuances

You should not start finishing the facade with paint if it is rainy or windy outside. high humidity will not allow the paint to adhere well to the base, and the wind will stick small debris on the newly applied layer.

Too hot weather is also not suitable. In this case, the paint will dry quickly, and small defects may appear. It is better to choose more stable weather conditions.

For faster and even coverage you can use a spray gun. Such a device applies a uniform layer of paint over the entire surface. But it requires the use of only a certain type of paint.
