Durable paint for concrete for the exterior and its application

The text discussed in detail this type of fabric as durable paint for exterior concrete work: existing types of formulations, their functionality and properties, characteristics, advantages and limitations. In this article you can find information to help you select and properly use the coatings for concrete surfaces exposed to outdoor conditions.

Durable paint for concrete for the exterior and the feasibility of its use

Concrete - a very durable and reliable material, endowed with many useful features. Therefore, it is widely used in the construction of the country for the construction of houses and refining sites. Concrete constructions, which are operated in outdoor environments exposed to negative effects of weather and climate.

Negative factors include the impact of:

• ultraviolet radiation;
• seasonal freezing and thawing;
• precipitation;
• mechanical load properties.

Additionally, concrete different hygroscopic, so its structure absorbs large amounts of land and water. For this reason, the material needs to be an effective and reliable protection that can reduce the negative impact of these factors. Since most of the finishing materials badly reacts to moisture, for this purpose it is recommended to buy paint for concrete for the exterior, with the appropriate operating conditions characteristics.

The use of such paint would improve the decorative properties of the concrete, to prolong its life, to hide fine unevenness and defects on the surface and also provide protection against moisture and biological factors influence.

Criteria for selection of frost-resistant paint for concrete for the exterior

Primarily quality coating must exhibit resistance to the influence of moisture. Because of this, the walls of the room will remain dry. High fire safety and resistance to combustion in the event of a catastrophic fire - another important criterion, which should pay attention.

Adhesive properties reflect how well the dye is fixed on the surface. The higher the number, the longer preserved paint layer on the substrate. If the composition has a low adhesion, finish very quickly begin to peel and flake. High resistance to direct sunlight is also important. If the coating does not resist UV, the surface quickly lose color and will burn out.

Useful advice! If the building is in a region with difficult climatic conditions, it is better to choose the most expensive and high-quality color. Budget paint option can not provide the necessary protection and adaptation painting works for the concrete will be much more expensive than buying a good composition.

Since the concrete structures are operated outdoors, it is necessary to pay attention to such criteria as the operating temperature range. The sharp change in weather conditions may affect the durability and the outer cover form, so it is recommended use paint for concrete on the street, which is able to withstand the heat and cold without loss of performance properties. Minimum required interval in the range from -40 to + 40 ° C.

This property of the dye as a water vapor transmission rate, provides access of oxygen to the surface, thereby eliminating the likelihood of the accumulation of condensation on the walls. Most high-quality formulations also are resistant to mechanical stress, which increases the life of the coating.

How to choose a facade paint for the exterior: the main types of dyes

Finishing materials for facades perform two functions: a decorative and protective. Qualitative coating is capable of retaining its properties and characteristics at very low and high temperatures. Some finishes perfectly operated at a temperature ranging from -60 to + 800 ° C.

In facade paints on concrete for exterior broad scope of application:

• basement structure;
• concrete walls;
• chimneys;
• system of internal and external pipelines.

Middle of the concrete surface dye flow is 250-650 g / m². This rate depends on the type of composition. The variety of finishing material dependent and other moments. For example, epoxy coatings group has the highest resistance to mechanical stresses. Using silicone, polysilicon, silicate or acrylic paints for exterior concrete requires careful preparation of the substrate, it should be clean and dry.

Coating materials for finishing the facade of the building increases the electrical performance a base, as well as provide protection against the effect of water, corrosive alkaline environment and oxidation processes. Quality coating not inclined to accumulate dirt and can be operated for at least 7 years.

Useful advice!If there is a need for eco-friendly and fire-resistant coating, experts recommend using water-based dyes. These compounds are diluted with water and do not react to an alkaline environment.

Classification of exterior paints for concrete according to the method of dissolution

As a method for dissolving dyes for facades are divided into two groups:

1. Water-soluble.
2. Formulations which are used for diluting solvents.

Water-soluble dyes are made of synthetic resins. Also, the composition contains further additives, pigments, fillers. Finishing materials are water soluble, have high throughput. They are resistant to ultraviolet radiation, temperature changes and mechanical stresses character. The average service life of this coating is 10 years.

Formulations which are diluted using organic solvents, can be applied to the surface practically at any temperature. Even high humidity is not an obstacle. As the solvent commonly used xylene, solvent or mineral spirits. Such coatings are not without drawbacks. These dyes contain toxic substances and are easily ignited. For this reason, compositions for diluting solvents are used which are less popular.

Feature popular paint for concrete for the exterior water-based

Water-based dyes are a large group of finishing materials. Epoxy compositions containing curing agents and resins have the highest operational parameters. Staining may be carried out at virtually any temperature. In this finishing material can perform the role of soil composition. Over time, the epoxy paint does not lose color.

The coating does not react with the chemical components and does not transmit moisture. In epoxy dyes has its drawbacks. These enamels are presented in the form of two components that must be carefully before application mix. Recoloration complicated by differences in the facade paint color, which is obtained after mixing and to that already applied to the surface. In addition, finishing emit harmful substances.

acrylic based compositions are applied to the previously prepared surface. To this end, the concrete should be cleaned by dry method or rinse and perform drying. It is recommended to apply the paint for exterior use on plaster, although acrylic compositions have excellent adhesive properties. On the surface coating is formed of high strength, it is not afraid of negative impact of natural phenomena, chemical and biological hazards such as fungi and mold.

Water-based dyes are substantially free of toxic substances. They are formed on the surface of a dense protective coating in film form. Using latex facade paint as a subspecies of water-based materials can give a coating with a water repellent.

Useful advice!Addition coats on the surfaces which are exposed to the influence of high humidity, it is advisable to use a further hydrophobic agent.

Features latex exterior paint on a brick for the exterior

Water-based dyes are easy to use, they are in high demand among buyers.

These compounds have a number of advantages:

• fast drying;
• absence of harmful substances in the composition;
• the smell of the dye quickly disappears;

• to adjust color exterior paint using special color scheme that allow you to virtually any shade;
• mixture is applied is very simple;
• after use, the paint tools are easy to cleaning procedure.

The use of water-based paints has certain limitations. Staining can only be carried out at a temperature above 0 ° C.

By type of water-based dyes bases are divided into the following types of compounds:

1. Silicone - for the manufacture of silicone resins are used. This type of coating is characterized by high steam permeability. In addition, silicone paints do not contribute to the development of the fungus.
2. Mineral - used as a basis of cement or lime. The material is not very resistant, but easy to use.

Characteristics of mineral façade paints, bricks for the exterior

Mineral paint for facades suitable for decoration masonry surfaces. Due to the presence of cement in the composition, the dye has such properties as water resistance and vapor permeability.

One of the biggest advantages of this coating is the ability to recover the paint layer. In the operation of any type of fabric is adversely affected by various factors. The resulting coating loses its novelty, covered with cracks and flakes. Mineral dye restores attractive look finish. For these purposes, a special solution. After the processing in the coating removed damages the original color is restored.

Note!By staining the walls can start only a month after construction. This is enough time to finish all the processes of leaching. And allowed an earlier painting, but only in conjunction with a special primer.

Features of acrylic paints for exterior concrete

Acrylic paint is equally suitable both for concrete and for masonry surfaces. Acrylic resins are used to manufacture these compositions. As a result, staining on the surface of a solid film is formed as a coating. It is capable of providing reliable protection from the influence of negative environmental factors.

The advantages of acrylic-based inks:

• environmental and safety;
• mixture lies well to the surface to be treated;
• excellent ability to take refuge;

• high density of the dye reduces material consumption during the application;
• Floor air permeability, providing ventilation surface;
• moisture repellent properties.

In some cases, a brick is poorly staining. To achieve the desired result using a special application technique. To do this you need to mix acrylic primer with a dye of the same type of brick. The application of this mixture does not cause problems, but the color lasts for 8-10 years.

Average prices of paints for outdoor works from popular manufacturers

On the market a wide range of paints for processing concrete. Among the Russian manufacturers are very popular epoxy paint Quality Technology Professionalism. This type of enamel is characterized by durability and a wide palette of colors. Dye price is about 400 rubles. per 1 kg of the mixture.

Dyes FLUGGER oil based prevent the formation of mold and mildew on a surface. After drying, the coating is easily washed. The average cost of dye - 700 rubles.

English Dulux brand offers an extensive range of materials, including acrylic, organic, water based paints and textured masonry paints. The average price for 1 kg is about 400 rubles.

Tikkurila dyes are very popular among consumers. This popularity is due to the application of a simple system, as well as excellent decorative coating characteristics. Approximate cost of the dye - 700 rubles.

Useful advice!Painting necessarily need to plan, taking into account the weather conditions, such as humidity and temperature, the presence of wind.

The use of facade paints: consumer reviews

Determine the choice of dye will help not only the characteristics of the compositions, but also customer reviews left on the forums:

"When there was a need for the acquisition of exterior paint, I was somewhat puzzled by the variety of materials. Often I heard good reviews about the compositions of the Finnish Tikkurila, but the price I was almost scared off. He decided to try it, trusting the opinion of the people, and not lost. Paint quality is really corresponds to the price. It turned out, if before coloring applied to the surface of soil composition can be reduced dye consumption. "

Eugene Doroshenko, city Moscow

"Tikkurila, of course, is good, but there are other colors, that the quality is not worse than nothing. For example, loofah or Nioksid. As a professional, I have seven years of use Italian and German finishing materials. During this time, I had tried many. Polish paint Snowball also offers good features and is easy to operate, with the price of the material is much lower than that of Tikkurila. Still I can advise Sin. All these colors are reliable and durable, so you can safely take to work. "

Sergei Makovsky, of St. Petersburg

Especially the choice of wear-resistant paint on the concrete floor

Any type of floor covering in need of a protective layer that provides strength and decorativeness. This requirement applies not only to the living rooms, but also the premises of industrial and warehouse premises, where the base is a concrete floor. Dyes for concrete surfaces prevent occurrence of cracks, increase visual appeal, durability and resistance to wear.

Safety floor covering is a mixture consisting of fillers, pigments, special purpose additives and acrylic resins.

Scope of such dyes apply to the following types of objects:

• handling facilities;
• parking lots;
• premises for production purposes;
• construction of ramps;
• coating on the roads.

With the dyeing compositions of the concrete may be treated the entire area, and also to carry out partial dyeing for marking a vertical or horizontal surfaces.

Characteristics of wear-resistant paint for concrete floors

Coatings intended for staining of concrete floors, characterized by high levels of resistance to the influence of atmospheric factors. They are not afraid of the impact of water and salty environment. Depending on the characteristics and the manufacturer's recommendations, staining can be a single layer or double layer. At a temperature of not less than
18 ºC dry composition occurs in a single layer for 30 min.

Note! Colorant for concrete surfaces is allowed to cover the floors in warehouses, where foods are stored. But you can start operating not earlier than the day after staining.

For painting we recommend using a roller or brush. Composition may be applied by spray. The optimum thickness of 6-12 mm layer. Wear-resistant paint can be tinted to any color. When the monolayer staining mixture flow is 250-350 g / m².

The data given in the table are approximate. Universal indicators do not exist, these parameters reflect the average performance, which can be considered optimal for most operating conditions.

The main types of paints on the concrete floor in the garage

Enamels intended for the treatment of concrete surfaces, significantly improve the performance of floors and walls. In addition, they provide protection from aggressive impact of chemicals.

By appointment Concrete dyes are divided into two categories:

1. For places exposed to precipitation.
2. For rooms with special climatic conditions, e.g., low or very high temperatures.

The most frequently used wear-resistant coatings, which are represented in the sale of a wide range of compositions:

• alkyd;
• epoxy;
• oil-based colorants;
• acrylic;
• alkyd-urethane mixture.

The use of acrylic paint for concrete durable coating is formed on the floor surface exhibiting resistance to wear. Paul, treated with a dye, has a high degree of protection against moisture. Acrylic compositions are universal, application of both outside and inside buildings.

Before painting, acrylic paint surface should be thoroughly cleaned of layers of dirt and dust. If the ground is too dirty, it is necessary to rinse with water and dry well. Acrylic dye is not only suitable for garages, but also for manufacturing plants. Strict temperature limits, at which the decoration, there will be implemented. Material reacts equally well both at high and low temperatures.

Note!The optimal composition rate based on acrylic is 650 g / m². If this figure to exceed the increase and the drying time of the coating.

The concrete floor may be processed and water-based dyes. For this purpose, suitable water-dispersible formulations, and mixtures of Latex. These advantages include environmental, fire resistance.

Features durable rubber paint for exterior

Rubber compositions for coloring concrete used to repair or finishing surfaces used indoors and outdoors. This type of material fits well and plaster (Except blanched surface), wood, plaster, asphalt, brick, ceramic tile. Therefore, rubber paint can be called universally applied finish.

Rubber dye can be processed:

• ramps;
• Inputs obliquely;
• walls and floors;
• individual elements of structures;
• The facade of the building;
• parking entrances.

It is not recommended to use this material for the treatment of sex, exposed to serious abrasive loads. Inappropriate This kind of coverage on furniture and doors.

Features and price of wear-resistant rubber paint for exterior

This type of coverage is a relatively new kind of decoration and protection of materials.

As part of the dye is:

• acrylate latex;
• water;
• coalescent (organic solvent);
• pigments;
• special additives with antifreeze and antifungal properties.

Rubber paints are safe for the environment and for people. Moreover, these properties are provided, and at the stage of coloring, and during further operation. Save and other properties of the coating film, such as mechanical resistance. In the dyeing process using a multilayer deposition technique. Rubber finish perfectly inhibits the formation of cracks. When this coating is highly transparent to air, so the composition of the treated surface "breathes".

Mean time "tack-free" drying - 30 minutes. to 1 hour. To fully drying the surface required approximately 12 hours. One liter of dye weighs about 1.1 kg. Protective Film very elastic, the degree of elongation reaches 400%. Due to this coating retains integrity during operation. Operating Temperature Range - -50 to + 60C. On average, the coating can last for about 10 years.

The average cost of rubber dyes:

brand name	L	Flow staining dye at a single layer, g / m	price, rub.
Superdekor	6	250	1120
Tikkurila Novas	2,7	170-250	2035
Thriving	12	225-250	2450
Rezolyuks Universal	7	150-200	2850

Useful advice! When working with rubber paint be sure to periodically stir up, to finish lay thinly and evenly.

How to calculate the consumption of rubber paint for concrete

A preliminary calculation of the flow rate will determine how much dye is required for high-quality staining facility. Due to this, the buyer can avoid unnecessary costs or the need to re-buy additional material. This will require to know what area of ​​the treated surface. The minimum flow rate during the initial application of 250 g / m².

On average, the cost of painting 1 m square is 35 rubles. To learn the necessary amount of dye needed a total area multiplied by consumption. It is desirable to add to the result of spare 10%. Dye consumption affects the quality of the machined surface. The smoother and smoother base, the less staff required for its coloring. If the porous zones apply primer, the number of voids is reduced, and therefore, reduce costs and increase the adhesive properties of the coating.

It will be appreciated that the repeated application of paint (second layer) is accompanied by a smaller flow rate, since all voids and surface defects are already filled. Not recommended for dilution water composition, even if the dye used in the water-based dispersed. Rubber paints is much more economical than some of the compositions. For example, for the treatment of similar area via an oil dye required 2-3 times more composition than is the case with rubber trim.

Useful advice!In order to eliminate unpleasant surprises, before proceeding to staining, it is necessary to put the paint in an inconspicuous place on a small area. This will allow an idea of ​​the density and color density, its shade.

Surface preparation prior to application of the rubber paint for concrete for the exterior

Staining concrete surface rubber compound is carried out in two stages. In a first step a base is prepared, the second - the dye deposition is performed.

To begin the surface is thoroughly cleaned by:

• grease stains;
• particulate chalk;
• dirt and dust;
• waste;
• old coating residues (if present).

If previously the concrete surface was colored dyes alkyd and oil-based, it should be completely clear. Thereafter the walls are washed with sodium phosphate solution. Then, the surface was washed with water and dried. If there are cracks on the walls or irregularities, they need to cover up or lightly sanded. After performing the procedures to get rid of construction dust.

Further Primers applied composition, it is desirable that it is deeply penetrated into the base material. If the object contains metal parts, staining need to carry separately, taking care of the application of anti-corrosion agents. Often used in the construction of cellular and porous concrete brand. In such cases, the surface is painted at least twice.

Concrete staining rubber compound technology and care for coating

The dye should be applied only on a dry surface. Before you get started, the composition should be thoroughly mixed. If the instruction provided to add coloring pigment, the material is mixed after its introduction. It is better if at least 3 layers to be deposited on the walls.

The paper is recommended to use a brush or roller. The first layer should be thin and neat. Repeated application of the composition is carried out only after the first coat of paint dried out. It takes about 1 hour. Between the second and third dye application is recommended to wait at least 2-3 hours.

When the work is finished, you need to immediately rinse with clean water the entire instrument until the dye is not dried up. The coating does not require special care, but the first wet cleaning is not recommended earlier than 7 days after dyeing. Possible to use a soap solution for surface cleaning and antiseptic agents.

Do not skimp when buying a dye, the majority of high-quality formulations for concrete, represented in Sales have a high price, which is justified by the high performance and technical characteristics.
