Paints for concrete. Choice, characteristics, prices

Despite the high strength and durability, the concrete surface is prone to chips, chemical attack and mechanical damage. The easiest way to protect it is to color it. Properly selected paint for concrete, in addition, greatly improve the aesthetic appearance of this material.

Protective function of paint

Often, as a result of wear of the concrete surface, characteristic dust appears on it. This is due to the high porosity of the material, and can also be due to its poor quality or a violation of the stacking technology. Special compounds, which are used for painting concrete, will help protect the surface from wear, destruction and exposure to aggressive environments.

In addition, the market offers a wide color palette of such colors, which makes it easy to choose a composition for any interior. Staining the concrete floor makes it more hygienic, facilitates care and hides all kinds of defects on its surface.

Types of paints for concrete

When choosing a paint, you should take into account the peculiarities of the room. In places where surface damage as a result of impact loading is possible, a more reliable coating is required.

Special paints for concrete - wear-resistant, containing solvents and epoxy enamels - will perfectly cope with this task. They are used not only in industrial premises, but also in garages, parking lots, hangars, repair shops, etc.

For interior or exterior walls, mainly acrylic paints (organic and aqueous) are used. Coatings of concrete surfaces with a composition on solvents are particularly strong, resistant to various aggressive environmental influences. Paints for water-based concrete are less durable, but in private houses, where there is not such a high load on facades, as in industrial zones, they are widely used by many owners of private buildings.

Acrylic paints

This is an aqueous composition based on acrylic resin with the inclusion of organic and inorganic pigments. The paint forms a fairly strong coating and is suitable for the treatment of concrete surfaces in garages, basements, utility rooms and production premises, on balconies. The polymer film it creates is a serious obstacle to various chemical and mechanical effects, protecting the concrete from corrosion.

Acrylic paints for concrete are highly environmentally friendly. They dries quickly and do not have a strong smell. In addition, they are resistant to moisture and high temperatures. Apply them with a brush, roller or with a paint sprayer, usually one layer is enough. Do not just apply acrylic compounds to the old epoxy or polyurethane coating. A great advantage is a wide range of colors, including matt, semi-matt and glossy colors. The cost is on the average 100-150 rubles per 1 kg.

Epoxy paints

The main advantages of these formulations are their ability to provide high strength and long service life of the coating. Such paint can withstand significant loads and is not afraid of the effects of acids, alkali, salt solutions and fuels and lubricants. The composition is well set with a concrete surface, does not turn yellow with time and does not abrade, so it can be used in places with high traffic.

Due to its resistance to various atmospheric phenomena, it can be used not only for interior surfaces, but also as exterior paint (outdoors, parking lots).

The disadvantages can be attributed to the fact that the two-component composition of this paint requires the obligatory mixing of it before application. And also it is rather difficult in the future to change the color of the coating, so you need to immediately determine the choice of the most suitable.

The price per 1 kg of epoxy paint for concrete is from 250 to 500 r per 1 kg.

Polyurethane enamel

A great advantage of this paint is its ability to create a perfectly smooth glossy coating. Suitable for both indoor and outdoor work. Despite the fact that its composition is two-component, it has excellent quality. Along with such properties as resistance to various damages, to atmospheric influences and environmental friendliness, polyurethane paint for concrete is very economical in application, has a high covering power.

The paint is applied at an air temperature of at least 5 ° C, and the relative humidity should not exceed 75%. Painting of the concrete surface is carried out in 2 stages. The second application is made no later than 24 hours after the first. The coating is completely mechanically stable after 7 days. Prices largely depend on the manufacturer and brand. On average, the acquisition of 10 kg of enamel costs 2800-3000 rubles. Polyurethane paint for concrete is considered an advantageous and very economical material for finishing.

Facade paints

As a rule, very high requirements are imposed on materials for facade decoration. In addition to providing an attractive appearance to the building, they must withstand the effects of all kinds of chemicals and temperature changes, have resistance against precipitation, ultraviolet radiation, fungus and mold, and have a sufficient level of vapor permeability.

In order to paint the material more qualitatively, a special facade paint for concrete is used, which has all of the above characteristics. It can be both polyurethane, and acrylic compositions on a water basis or on organic solvents.

The life time of the facade paint depends largely on the quality of the adhesion, so when choosing the finishing materials, special attention should be paid to those in which acrylic and vinyl resins, potassium glass, lime or cement are the binding agent.

Rubber paints

The product of the new generation is called this universal finishing material. This paint is suitable for processing both dry and moist surfaces. Due to its elastic structure, such a coating will never crack and will not peel off, has a very pleasant to the touch texture. Absolutely harmless to the human body composition have rubber paints for concrete. Caring for such a coating is very simple, just wash it with soap. Creating a film that does not burn out in the sun, the paint protects the concrete surface from the negative impact of the environment, while allowing it to breathe.

One of the advantages of these compounds is that the surface treated by them has anti-slip properties, which is very important for concrete floors. Thanks to the wide color palette, which distinguishes rubber paints for concrete, they not only fulfill the role of a quality coating, but also are suitable for solving any design idea. The price of one kilogram of paint from 120 p and above.
