How to choose a facade paint for concrete?

Concrete is a durable and reliable material, endowed with many useful properties. The material is widely used in construction, it is used for different purposes. Concrete structures in open space are constantly exposed to the negative influence of environmental factors. Therefore, they require special care, which can guarantee only quality coverage.

The use of facade paint on concrete will improve its decorative qualities, increase the service life, hide minor defects and irregularities on the surface. However, many do not know how to choose a facade paint for concrete.

Since concrete systems (especially those that are in open space) are unstable, the requirements for facing solutions for these surfaces should be exaggerated. Consider the main criteria.

• Adhesion. Facade paint should adhere well to the base to be painted and penetrate it.To improve this quality, before applying the coloring composition, experts recommend treating the surface with a deep penetration primer.
• Moisture resistance. Given the fact that the concrete coating absorbs moisture well, manufacturers of coloring materials include additives that repel any liquid in their products.
• Wear resistance. The property characterizing the duration of the service life of the coloring matter. The more negative influences a facade paint can withstand, the better its durability.
• Resistant to UV rays. Ultraviolet radiation has a detrimental effect on the coloring pigment of the facing material. If the indicator of resistance to exposure to sunlight is weak, the paint quickly loses its visual appeal, it will fade, may flake off over time. Therefore, the compositions for facade use must be distinguished by a high degree of resistance to the rays of the sun.

• Vapor permeability Paints for external use must give up moisture accumulated by the concrete structure, otherwise the surface will collapse.
• Resistance to pollution. Coloring solutions of most manufacturers are characterized by good resistance to contamination: they do not absorb dirt, they are easy to clean. If the painted surface is perfectly flat, the dust on it will accumulate less than on a curved coating.
• Drying time The faster the dyeing material dries, the less likely it is that the concrete structure will deteriorate (the facing mortar must dry as quickly as possible).
• Consumption per 1 m2. Since the concrete absorbs any liquid well, the consumption of the coloring composition will be large. In each case, you need to build on the characteristics of the purchased paint.
• Brightness. The saturation index is associated with the cost of the coloring matter: the higher the saturation, the greater the consumption of the facing material.

A wide range of materials is presented on the market of paints and varnishes for concrete. Consider the most popular formulations with customers.

It is a matte solution, has excellent decorative characteristics.The main element is polyacrylates. This paint reliably protects the concrete base from damage by a fungus, it is easy to clean, it does not have a specific chemical smell. It dries quickly, has excellent vapor permeability. Service life is 10 years.

The advantages of this type of coating include strength and environmental friendliness, as there are no toxic substances in its composition. Acrylic retains the brightness of the surface, regardless of the life of the paint. Acrylic paint is used to treat external and internal surfaces. All objects painted with this composition are reliably protected from moisture, they are distinguished by a high degree of wear resistance.

This paint creates a beautiful durable layer, which practically does not get dirty. Apply this compound to the pretreated primer and dried surface.

Polymer paint, unlike other types, is not afraid of lowering the temperature, it can be used even in severe frost.The polymer coating is not afraid of shocks, it resists the negative effects of chemicals. It is convenient to apply this paintwork material not only with a brush, roller, but also with a spray.

Water-epoxy base - a combination of dye and primer. The product is safe for the environment and humans, they can paint the surface in homes and buildings for commercial purposes. The solution repels moisture, it is durable. Before painting the surface with this composition it is necessary to mix the mixture thoroughly and wait 15 minutes until the components begin to interact with each other. After that, you can begin coloring. The process of surface treatment consists of two stages.

• On the first one, the first layer is applied, which should dry well (it will take at least 18 hours).
• Then put the second layer, its drying is much faster (high enough ambient temperature).

Vinyl paint has a high fill factor. It is homogeneous, in terms of decor, the most successful. This paintwork material is not erased with time, it has a characteristic matte texture.This paint can be used to apply on the surface of the facade and interior walls. Before painting the solution is well mixed. Be sure to priming the surface before painting. After that, the tool is evenly distributed on the concrete base with the use of a brush, roller and even a spray bottle.

Paints of this group are applied to the concrete base twice. The first (base) layer dries for about three hours, then a second layer is applied to the surface. Such solutions have advantages over other analogues due to acrylic and silicone, which are part of. These varieties fit well on the surface, have high adhesion and dry quickly. Silicone resin in the paint increases its elasticity and strength, due to which dust and dirt are not attracted to the solution. The only drawback of such paints - poor color palette.

To date, there are different in properties and characteristics of facade paint on concrete, among them there are smooth and textured varieties. The latter are denser and more qualitative: such materials hide minor flaws and flaws in concrete surfaces (for example, cracks,small pits). Decorative features of facing materials are characterized by tinting and the percentage of reflection.

The percentage of reflection is an indicator of how paint reflects solar or artificial light from a surface. For painting concrete structures often buy paint solutions with a dull reflection. Their main difference is higher vapor permeability. Less commonly, semi-gloss paints are used (they are mostly chosen for decorating individual elements of concrete surfaces).

The building materials market is replete with a huge assortment of paints for concrete. This product is produced by many companies, among them is a well-known company known to many consumers. Tikkurila (Finland), due to the high quality of products. In the Russian space, paint products of the brand are in great demand, their quality satisfies every customer. The front paints of the Tikkurila brand can be enjoyed by consumers with different financial capabilities.

The cost of facing products depends on the class of the mixture,There are budget options and premium products. The company's range of products includes paints for facade works. Kivisil (based on the product silicone emulsion), "Novasil" (acrylic lining), as well as other types of coatings. The diluent of such paints in most cases is water.

The dignity of the Tikkurila coating compositions is displayed in their mixing system. In the presence of the client in the cabin with the purchase of produce the necessary color.

Demanded Russian manufacturer of facing solutions is a company Elcom. The quality of products meets all existing European standards. Facade paints are made on a silicone basis, due to which they have high weatherability and vapor permeability. In addition, these materials are resistant to UV radiation, they can be used at sub-zero temperatures.

In the territory of the Russian Federation organizations are engaged in the production of paints for concrete "Olivest", "Neva colors". Popular from the population and the colors of the concern "Palette"especially the coating series "Tury". The quality of the products of the above manufacturers meets all the requirements of modern standards and the wishes of customers. These coatings provide attractive appearance of concrete.
