Varnish for concrete. Types of varnish for concrete

Concrete is endowed with many good qualities: strength, durability, high wear resistance and frost resistance, resistance to corrosive environments and temperature differences. Nowadays, this material is used for many construction purposes - for the construction of floors, walls, foundations, etc. But, despite its excellent protective qualities, concrete itself requires protection, and for this purpose, special varnishes on a different basis are used.

Varnish for concrete: application

Lacquer mixture is able to protect concrete surfaces from virtually any impact, and most commonly used:

• As coating for concrete floor;
• On fences and fences using natural stone and concrete;
• On concrete garden paths, sidewalks and other objects, which are constantly exposed to atmospheric influence.

Benefits of using

As practice shows, varnish for concrete and stone not only protects against moisture, corrosion, but also increases the strength of the material. When covering the concrete base, the following results are achieved:

• Increases the service life of the material;
• Concrete becomes more stable and durable;
• Resistance to abrasion increases significantly;
• Frost resistance increases;
• Improves the appearance, the surface becomes glossy (if used as a finishing coat);
• The service life of the processed object increases.

Prices for varnish for concrete depend on the basis on which they are created, and range from 100 to 2000 rubles. For one liter.

Classification

Concrete lacquer is classified according to the following parameters:

• Base composition;
• Color, fire resistance, quantity of anticorrosive additives;
• Light reflection.

As a basis, one of four substances is used: polyurethane, polymer, silicone or acrylic. In this regard, the varnish for concrete can be:

• Polyurethane . It has improved water retention performance, so it is most often used on surfaces that are most susceptible to moisture.
• Polymer . The protective agent does not pass moisture, quickly dries. They easily cover large areas.
• Acrylic . Due to its high cost, it is mainly used as a decorative coating on small surfaces.
• Silicone . In its characteristics, it combines high moisture resistance and good decorative qualities.

Each of the listed species has its own distinctive features and scope.

In addition to the protective property, it is necessary to note the possibility of creating different reflective effects. The varnish happens:

• glossy;
• Semigloss;
• Semi-maturing;
• Matt.

Polyurethane varnish for concrete

Products on a polyurethane base are the most popular and common. They have good penetrating and protective properties. To achieve a greater effect, the impregnation on a polyurethane base is pre-applied.

Polyurethane varnish refers to the average price category. Its cost is 150-300 rubles. For one kilogram.

Among the many proposals experts recommend choosing products of the brand "Tistrom". This protective agent is excellent for coating in shops, car service centers, garages and other similar structures. It has the following advantages:

• Resistance to oil products, oils, gasoline;
• Ease of use;
• Good decorative qualities;
• Does not lose its properties and is not damaged by wet cleaning.

This tool not only provides a durable and wear-resistant coating for the concrete floor, but also imparts additional tensile and compressive strength. Often this varnish is used as a base in industrial premises, ancillary rooms, barns, poultry farms, etc.

Lacquer on a polymer basis

Such protective agents have good wear resistance, strength, water resistance and resistance to aggressive media. They are referred to the category of quick-drying, which reduces the time of work on the opening of floor coverings, especially a large area.

Typically, the basis of these varnishes is styrene, which gives the product and the treated surface additional qualities: chemical resistance and high strength. The cost of polymer varnishes is the most profitable - 15-25 rubles. For one kilogram.

The most common polymer-based agent is Texol.

Lacquers on a silicone-acrylic base

This is the most expensive means. Their price per kilogram is up to 700 rubles. The high cost is justified by the relatively low consumption and the possibility of performing work under the conditions of the current production. After application, the varnish gives the surface a matte color. The most popular products are the brands Element, Wet Stone, Orion.

Water-based varnishes

This category is most often used to cover wooden surfaces and decorative colorless concrete. An example of a water agent for concrete is the two-component varnish of PaliStone FP. It is used for coating concrete, artificial and natural stone, paving slabs and other surfaces.

Recommendations for application

Any varnish for concrete will serve much longer if you adhere to the basic rules of its application:

• Clean the surface, get rid of dust;
• Check humidity (no more than 4%);
• Surface priming;
• Prepare a protective agent: one-component can be used immediately, a two-component varnish is used after mixing its constituent parts.

Application is done with a brush or roller. Drying time is approximately 2 hours. If necessary, a second coat can be applied.

After coating, you can walk on the surface after 5-6 hours.
