How to choose frost-resistant facade paint for exterior work?

In assessing the result of the construction or repair of any building, an important aspect is its appearance. Impeccable facade finish adds value to a new house, and the old building returns the former gloss and neat look. Especially important is the choice of shade, in harmony with the overall composition of the site, and the correct facade paint, which will preserve the beauty of the building for a long time, without succumbing to the ravages of the climate.

Almost throughout the territory of Russia in winter there are sub-zero temperatures, and in the northern regions there are severe frosts. Modern technologies allow to produce facade finishing materials with the properties necessary for harsh conditions.

Any outer coating must meet the following requirements:

• to preserve their best qualities in spite of the loads experienced during the operation;
• to have high decorative qualities, to keep the declared shade or texture during the entire period of use;
• do not prevent the escape of steam from the walls, otherwise frozen drops of moisture during the expansion will destroy the building;
• be elastic so as not to crack when the house shrinks;
• protect walls from water penetration;
• be resistant to temperature fluctuations, severe frosts, ultraviolet radiation.

The market of building materials offers a huge range of high quality facade paints. Weatherproof paint not only meets the specified requirements, but also has a lot of undoubted advantages and special properties, including:

1. strength and durability;
2. wide range of working conditions;
3. moisture resistance;
4. incombustibility;
5. resistance to mold, bacteria, fungus;
6. quick drying;
7. low toxicity;
8. ease of application;
9. ease of care and cleaning.

The paint consists of a filler, a pigment and a binder. The more in the composition of the binder, the higher its cost.

Facade paints vary in their composition and scope.

Water-based materials are produced ready for application, they do not need to be diluted, which is very convenient and suitable for owners who do not have special skills and make repairs to the facade with their own hands. They are used for painting concrete, brick and plastered walls. The composition can be applied with a brush or roller, it dries quickly and creates a durable and waterproof coating that is resistant to all weather conditions. Such paints are quite affordable and are very popular among buyers.

The disadvantages of this type of paint a little. It is applied only in good weather. - no rain, cold or heat, which interfere with the normal evaporation of moisture during drying and may affect the technical characteristics of the coating. The composition of water-based requires a preliminary leveling of the surface, as well as its treatment with a primer.

The silicate coatings include antifreeze additives, lead oxide, and chromium oxide; The recipe may contain azure and liquid glass.These paints create a transparent coating and are used to create drawings on the walls of buildings, paint concrete, brick, stone, ceramic walls, as well as for road markings.

Such compositions should not be applied to surfaces pre-painted with glue or vitriol solutions. - it threatens with flaking of silicate paint. The disadvantages include high toxicity and high consumption of material that must be applied in several layers.

Silicone paints are a water emulsion of silicone resins.. It must be diluted with water before use, stirred, then add pigment and hydrophobic liquid. After complete drying, it has a high elasticity, breathes well, and prevents the formation of mold and mildew spots. Frost-resistant silicone paint can be used on stone, concrete, brick walls, as well as plaster.

It creates a matte finish, visually making the surface perfectly smooth. In addition, it has the property of self-cleaning - even a small rain washes away all dust and dirt from the walls.The paint is sold as a white base and tinted before use. In addition, the material has almost no odor.

Acrylic frost-resistant materials are produced on the basis of acrylic acid with the addition of latex, defoamer and other useful ingredients. A layer of such paint forms a high-quality decorative coating of high strength. There are compositions of water-based and organic solvents. Acrylic material dries quickly: the first layer dries from 30 minutes to 2 hours, the second - completely dries in 24 hours. The composition based on acrylic does not fade, transfers shrinkage without deformation, has a high hiding power (it is enough to apply the composition in two layers). The service life of the coating is 7 years.

Among the shortcomings it can be noted perhaps that the relatively high cost, which includes the purchase of color plates. During the work it is necessary to ensure that the container with paint was closed. Despite the price, this type of paint is most in demand among buyers. The composition of oil paints have toxic components that have a pungent smell. Apply such paint in 3-4 layers. The binding component in them is the linseed oil.Apply these compounds for painting metal and wood surfaces. The lack of oil paints can be considered a limited service life, since the winter weather and summer heat still gradually destroy the integrity of the paint layer.

To make repairs on their own or competently monitor the work of the team of dressers, it is necessary to study the main stages and details of the painting process and prepare the following tools:

• putty knife;
• roller, brushes, roller tray;
• spray gun or spray in the case of mechanized method of application.

Before buying it is necessary to calculate the paint consumption per 1 square. m - for different types of coatings, this rate is different. To make the correct calculation, it is necessary to add 10% to the figure indicated on the packaging of the particular paint chosen, since the determination of consumption occurs in laboratory conditions at the enterprise, but in reality a part of the material can be wasted.

First you need to prepare the surface of the walls - clean them from the old layer of paint, seal up all the irregularities, cracks, chips with a putty.If the wall is severely damaged and crumbled, you need to plaster it completely, then remove all dirt and dust. The surface must be dry and clean - then the paint will fall correctly and evenly. After preparation, the walls should be primed.

It is necessary to paint in a dry warm weather without a strong wind. It is necessary to apply a frost-resistant composition in at least two layers depending on the density and hiding power of the type of paint used. The interval between the application of the first and second layer varies from 30 minutes to 2 hours. Complete drying of the surface occurs in a day. This coating no winter is not terrible.

There is a huge competition in the market of finishing materials, therefore manufacturing companies are constantly developing new innovative compositions, expanding the line of their products. Among the brands most famous Dulux, Tikkurila, Pufas, Alpa fasade. Among Russian brands should be noted "Optimist", "Halo", "Admiral".

The leading position in Russia is deservedly held by an international company. Tikkurila. The success story of this manufacturer began more than 150 years ago in Finland. Many significant buildings in Russia are painted with Tikkurila paints: temples, museums, stadiums, architectural monuments and super modern business centers. The richest color palette has 20,000 shades.

The materials of this company have unique formulas that are absolutely safe for human health and the environment. These compounds are hypoallergenic, which allows them to be applied even inside kindergartens, hospitals, and rooms with increased environmental requirements. After complete drying on the painted surface, a strong and durable vapor-permeable coating is created that does not fade in the sun, is easy to clean, protects the wall from dust and dirt, as well as moisture.

With subzero temperatures and other adverse conditions of use, this quality product fully retains all its basic characteristics. The approximate consumption of such facade paint is 150-200 ml per 1 sq. Km. m It is possible to apply structure in any way: roller, brush, spray.

Whatever surprises frosty winter may present, a house covered with weather-resistant exterior paint will look great and neat. It will not change its original color even after many years.
