Varnish for concrete: varieties of compositions on

In the modern world, concrete is almost the main material for the construction of capital structures: walls, ceilings, foundations, floors. But, despite all its advantages, he, of course, requires protective measures. And no matter how strange it sounds, there are several options that will help you in this, for example, polyurethane varnish for concrete, but first things first.

Variety of coatings for concrete

To protect the concrete, after pouring and gaining full strength, special lacquers are used, which significantly increase its quality characteristics:

• Durability.
• Strength.
• Moisture resistance.
• Frost resistance

Interesting! There are tools that are applied and rubbed into the still fresh and uncured concrete - topping. A process that requires little skill.

Most often used for coatings on a concrete base varnishes based on:

• Polymer.
• Polyurethane.
• Acrylic.
• Silicone.

Each of them, in turn, has distinctive properties and scope, in more detail you will learn about it from the following sections:

Polyurethane Based Varnish

Полиуретановое средство является, пожалуй, самым популярным видом покрытия. Его отличительной чертой являются прекрасные проникающие и защитные свойства. При использовании в сочетании с предварительным нанесением пропитки на идентичной основе, эффективность полиуретанового состава возрастает в разы (см.также статью «Сетка для бетона – виды и применение»).

Impregnation - soils significantly increase:

• Adhesive surface abilities.
• The degree of hydrophobicity (repulsion of moisture).
• Wear resistance that allows to use this type of a covering for the concrete surfaces which are exposed to rough terrain.

In addition significantly prolong the service life of structures, as they allow to achieve the best operational and technical characteristics.

Polyurethane varnish on concrete for exterior work is used more often than other coatings, although the price for similar compounds is in the range of 150 - 250 rubles per kilogram.

Polymer-based varnish

Varnish for concrete floors and other concrete surfaces on a polymer base, as well as polyurethane forms a coating with excellent characteristics:

• Abrasion resistance.
• Increased strength.
• Higher than polyurethane analogues water resistance and resistance to aggressive media.

Also polymer lacquer belongs to the category of quick-drying, which makes it possible to reduce the time of work. This property is especially important when working with large surfaces.

Note! Polymeric compositions, as a rule, are prepared on the basis of styrene. This is what causes their high strength and chemical resistance.

The cost of polymer varnishes is 15-25 rubles per kilogram, which, you see, can not be called burdensome for the budget.

Varnishes on a silicone and acrylic basis

• The most expensive representatives of the concrete varnish family are silicone and acrylic. Their prices reach 700 rubles per kilogram, and are compensated only by a small consumption of such varnishes per surface unit.
• In addition, the advantage of varnishes based on silicone and acrylic is that the execution of works on the surface coating does not entail a halt in production.

Note! Any and all varnishes for concrete can be selected by color, the presence of inclusions (fillers) and the degree of glossiness.

Concrete coating technology

Fans of doing the work with their own hands should understand and how it is done in practice.

For a start, very important information:

• Concrete surfaces of a large area are divided into maps by temperature seams. For this purpose, the reinforced concrete is cut with diamond circles to the depth specified by the project.
• The seams are filled with a material that easily transfers and absorbs deformations in structures arising from temperature differences and natural movement during shrinkage.

Note! If necessary, diamond drilling of holes in the concrete is also performed prior to coating.

Now directly step-by-step instructions for performing work on the coating of concrete surfaces:

1. Preparatory stage:

• The concrete surface is cleaned.
• Dust free.
• If, on drying out on concrete, efflorescence has appeared, they are cleaned more thoroughly - with grinding equipment.
• Based on

1. Main stage:

• The varnish is applied to the prepared concrete with a brush, roller or sprayer, depending on the nature of the surface.

Tip! Coating of concrete surfaces on the outside is carried out in dry weather and moderate temperatures.

• Drying time "to touch" is from one to two hours.
• If necessary, apply the second and subsequent layers of work resume after two to four hours, you can walk on the painted floors in five hours, and after a day - you can start equipment in the room.

Using similar technology and materials it is possible to arrange coatings not only of concrete, but also of stone, brick.

Conclusion

Надеемся, что вышеописанная информация позволит вам сделать правильный выбор и сэкономить при ремонтных и строительных работах. Что же касается непосредственного нанесения защитных средств, то, как вы уже поняли, любой хозяйственный мужчина способен произвести их самостоятельно (читайте также статью «Усиление железобетонных конструкций: основные методы и их особенности»).
