Facade paint for concrete for exterior work: the pros and cons

Repair and decoration of the facade of any building can take a lot of time. First of all, it is necessary to determine the choice of material, because in the market there are many varieties of products from various manufacturers. Make a purchase must be balanced, taking into account the features of coverage. If we are talking about a concrete facade, then there are several options for it, while it is important to pay attention to the features of the surface, and then the purchase will be repaid.

Special features

The first requirement that is put forward to any finishing material is endurance to external influences and mechanical damage. The outer lining is always exposed to temperature changes, direct sunlight and high humidity in a particular season.Therefore, it is important to choose a paint that will not only keep the surface presentable for many years, but will also be durable, reliable and will not collapse. The main indicator of facing materials is adhesiveness.

The task of covering the facade is to protect the surface from moisture, fungi and other unpleasant consequences of the influence of weather conditions. At the time of purchase, pay attention to the characteristics of the material.

The facade of concrete has several advantages, but you need to pay attention to some features that affect the choice of cladding. The base, as is known, is porous and rough, and therefore has the ability to absorb moisture and store it in the upper layer. Thus, covering the facade with paint, you protect it from the harmful effects of water and improve the appearance of the object.

Specialists who are engaged in outdoor work, know how demanding and capricious concrete walls. The paint that you are going to buy for finishing should have a high penetrating power for strong adhesion to the main surface material.

It is recommended to apply priming before applying the agent in order to increase moisture resistance.One of the important indicators of paint is abrasion, so the material must be durable.

Most of the facing materials on the market copes with pollution, as they do not absorb dust, so it is easy to care for a covered facade. To speed up the drying time, you need to consider the type of paint you have chosen. Work is recommended to carry out in a dry time.

Species

In the hardware store you can offer several options for the material. Dyes differ in a set of characteristics and advantages that are recommended to be studied before purchase in order to compare all the pros and cons. The classification of the material depends on its composition.

Acrylic paints include polyacrylates and polymers, among which latex linings can be found. Such products cope with high humidity, is resistant to abrasion, but The main advantage is the absence of harmful impurities. In the paint there are substances that increase its elasticity. As for the disadvantages, it is poor frost resistance, therefore it is not recommended to use it in certain regions.

The next type of coating - water-epoxy material, which is considered to be universal, as it is suitable for different types of surface, in addition to concrete. The moisture resistance of this product is high, but it is not able to maintain brightness with prolonged exposure to sunlight. Polymer paints have good wear resistance performance and they cope with temperature changes. Such a composition dries out for a long time and is somewhat more expensive, which is not such a big disadvantage with other advantages.

To cover the concrete facade will be enough one layer, if you use vinyl material. It is offered in a wide range of colors, and also has high wear resistance. If we talk about resistance to the sun, then acrylic-silicone materials are most in demand. They are suitable not only for exterior but also for interior work.

Paints that can be dissolved with water are suitable for covering the facades of the building, and they should contain synthetic resins. There are options on the market with flammable substances that need to be diluted with an organic solvent. Such materials for facing are not so popular.When choosing products for finishing the facade, you must select materials that have a smooth or textured structure. You can choose matte or gloss paints, depending on what effect you want to get as a result.

Color consumption

Concrete requires the use of a large amount of cladding material, as it is porous. It all depends on the characteristics of the paint and its saturation, since the more it is, the less money you will need. Consumption per 1 m2 depends on what is included in the composition of the coating agent that you have chosen. It is recommended to be guided by the following indicators for one square of area:

  • acrylic composition: 0.4 kg;
  • polymer composition: 0.35-0.4 kg;
  • oil composition: 150 g;
  • water-epoxy composition: 0.25 kg;
  • vinyl composition: 0.2-0.25 kg;
  • acrylic-silicone composition: 0.1-0.3 kg.

The first two layers should go thick consistency of the source material. If the paint is liquid, it will disperse faster and more, so when buying, consider this point.

Since it is necessary to veneer a concrete facade, up to seven liters of material may be needed per square meter.As for the last layer, it all depends on the type of paint.

How to choose?

Before buying exterior paint for exterior work, pay attention to the following tips:

  • When buying, consider the ability of the finishing material to provide vapor-tightness. Experts say that this is one of those indicators that you need to pay attention in the first place.
  • Of great importance is the consistency and density of the coloring composition.
  • Of course, we must not forget about moisture resistance, strength and duration of fading.
  • Be guided by a small but important piece of advice — choose a paint that reflects light well, since fading will be minimized in this case.

The time it takes to dry the surface depends on the type of paint you purchased. It should be noted that the facade works take place in several stages, since two and sometimes three layers of finishing will be required to be applied to the surface. But it is necessary to wait each time until the previous one is completely dry. The inner layers are ready for re-painting in 2-5 hours, and the topcoat dries in 24 hours.

For buildings that are located in a region where there are difficult climatic conditions, it is better to use expensive formulations. Otherwise, soon the lining will have to be updated, and these are additional expenses. The cost of high-quality paint for facing the facade can be quite high. But it must be remembered that it is not only about the appearance of the surface, but also about the protection of the materialas concrete has a tendency to crack and crumble due to temperature and weather conditions.

It is important to purchase a high-quality painting composition that will cope with its task and prolong the life of the facade. The paintwork must have a protective function against water, mechanical stress and fire.

Before buying, you can consult with qualified professionals who work in the construction industry and can give useful recommendations.

External works require not only professionalism and experience, but also the right material that will make the surface beautiful and protected. Therefore, use the above information to make a profitable and practical purchase, and the result will surely meet your expectations.Successes!
