During the construction of the house, decorative facade plaster is used, which is necessary for leveling the walls before finishing and painting. The choice of such a building mixture must be approached seriously. Regular putty suitable for interior decoration can not be used. For exterior work there is a special type of putty.

The main advantages of the facade putty

The main qualities of the building mixture are not only its protective functions from various external adverse forms of exposure, leading to the destruction of surfaces, but also the creation of a beautiful facade design. External plaster is characterized by the following properties:

  • Strength. Mechanical loads are rarely exposed. If the walls for any reason will experience such loads, the plaster layer will protect against destruction.
  • Water resistance. This type of building mixture under the influence of moisture does not change. Putty is a protective coating that prevents the destruction of walls by water.
  • Vapor permeability External plaster is a breathable building material, that is, it allows oxygen and vapors to pass outside, thereby maintaining the original surface structure of the building wall.
  • Good thermal insulation and sound insulation. Outdoor putty helps to preserve heat in the house and reduce the level of street noise.
  • Resistance to climatic changes and sudden temperature changes. High-quality putty for facades has a high resistance to aggressive sunlight, various precipitations, and even to radiation compounds. Facade plastering is performed under adverse climatic conditions.
  • Easy to use. Plastering surfaces can be carried out independently, if there is little experience in construction.
  • The possibility of using for interior decoration.
  • The embodiment of various design solutions and a large selection of colors. With the help of decorative facade plaster can embody any design ideas. A variety of color palette is obtained by adding colors to the building mixture. You can create different patterns and textures, while correctly, correctly applying layers of material. The choice of color and ornament depends on the design decision and technology of the coating.
  • Cost In comparison with other finishing materials, wall plastering is more profitable. The price per item depends on the structure of the coating and its properties.

These characteristics are available in almost any decorative type of facade putty, but it is worth knowing that the degree of manifestation of certain properties may differ from the type of mixture selected and its components.

Depending on the purpose, the facade putty for exterior work is the following:

  • Starting. This type of putty is used for the bottom finish (base layer) of the surface. The structure of starting mixtures is coarse-grained. The thickness of the application of the starting layer of putty varies from 2-20 mm. These mixtures are very durable, easy to process. Due to these properties it is often used for leveling the surface.
  • Finish This putty is applied at the final stage of facade work, with the help of it the surface becomes even and smooth. The structure of the finishing mixture is fine. The thickness of the layer of putty no more than 4 mm. If necessary, additional painting is carried out. In comparison with the starting finish putty is not as strong.
  • Universal. This type of putty combines the properties of the two previous ones. For finishing the exterior facade such fillers are used extremely rarely.

The technology of applying facade putty

Apply the facade putty only in two ways:

  • mechanical;
  • manual.

In the first case, mortar is applied to the surface with a special device under high pressure. This method has disadvantages: uneven application of layers of plaster and high demands on the finished mixture, so the manual method is more often chosen.

Before applying the putty it is necessary to clean the surface from particles of dust, dirt, greasy stains. To prevent the development of the fungus and the strength of adhesion of the layers, it is necessary to treat the walls with a special solution.

There are always high demands on decorative facade putty. The main criterion for their selection is resistance to various climatic conditions. Selecting the facade putty carefully examine its filler (its fraction) in the material and technical characteristics. From this will depend on the evenness of the processed walls. Layers of plaster will lie more evenly if it is less. Cement hard putties have a large granular fraction, but despite this they are more in demand. Ready-made paste mixtures have the best properties.

High-quality facade putty should meet the following requirements:

  • quick to grab;
  • do not crack;
  • be durable and plastic, that is, for a long time to maintain its "viability";
  • be easy to handle;
  • possibility of combining with used paintwork materials.

For a long time, decorative facade plaster remains a finishing material for residential buildings and houses for various purposes. With its help, you can carry out your ideas by applying different shades and patterns. A wide range of facade putty is on sale, thanks to which everyone will be able to choose the right mixture.
