The most obvious purpose of paint or plaster when applying them to the walls of the house is to give the surface a more attractive, renewed appearance. However, this is not the sole task of the finishing material. It is equally important to protect the base material and the occupants from the adverse effects of the environment. For example, noise can be protected with noise insulation paint and plaster. Other types of insulation materials are protected from humidity and electric current. This article will deal with the types and features of the use of insulating materials.

    Insulating materials can be used to protect buildings of different types - not only residential but also for technical purposes. Insulation can protect the room from excessive humidity, electric current and noise.

    Protection against moisture

    The issue of waterproofing is one of those problems that can be solved with the help of paint and varnish. It should be noted that most of the paints, one way or another, has waterproofing properties. However, if you need a really serious defense, you can not do without a special paintwork. After coating with such a composition, the surface will withstand even the direct action of water for a long time.

    The waterproofing paintwork material should have certain qualities:

    1. The paint should be used for interior work and for finishing the facade, because two-sided painting provides more reliable protection.
    2. It is desirable that, in addition to moisture resistance, the paintwork material is resistant to ultraviolet rays and temperature changes.
    3. The composition should include anti-salt additives and antifungal agents. Antiseptic qualities are very important for good waterproofing, because moistened material is an ideal place for the development of mold and fungus.

    Please note! The quality of the paintwork is influenced not only by the expiration date, but also by the storage conditions. The paint should not be in very cold rooms( at minus temperature) or too hot. Information on the terms and conditions of storage can be found on the product packaging.

    Sound insulation

    The increased level of sound insulation can be achieved by painting the surface with a special paint. Noise-inhibiting coatings have a number of characteristic features:

    1. As a basis for this type of paints is a bitumen or acrylic composite element. Both substances have a number of features: acrylic is better suited for internal work, since it is practically devoid of odor( water base), and bitumen is much more effective in the street, but it is not suitable for premises, because it smells unpleasant. At the same time, bitumen varnishes are much cheaper than acrylic paints, which is important when painting large areas.
    2. The maximum level of noise insulation can be obtained if the composition is applied in a thick layer. As a working tool, it is recommended to use a brush or a roller. Dissolves the paint in a synthetic composition.
    3. For isolation of moving elements( for example, machine parts or car parts), the paint based on bitumen is best suited. This group of paints can absorb not only sounds, but also vibrations.

    Electrical insulation compounds

    For protection against current, special paints with electrical insulation properties are produced. The cost of such paint is quite high, but the value of electrical insulation is great, because the safety of tenants depends on this. The main qualities of electrical insulating paints( besides the main one - protection against current) are the durability and resistance to other negative environmental influences( ultraviolet, moisture, temperature differences, etc.).

    There are different brands of electrical insulating compounds on the market, the most common of them are:

    1. EP-969 is designed for painting metal pipelines. The enamel is heat resistant and can withstand temperatures up to 150 degrees above zero.
    2. EP-919 is used for processing a variety of metal surfaces. A characteristic feature of EP-919 is its high anti-corrosion properties.
    3. GF-92 and EP-9111 are most often used for painting windings on electrical equipment.

    Please note! The application of an electrically insulating coating is a very important task, so that without the experience it is possible to carry it out with your own hands. It is better to assign such work to specialists.

    Other types of insulating paints

    Among other varieties of paint and varnish insulators, it is necessary to isolate thermal insulation and thermal insulation compositions.

    Thermal insulating coatings can withstand heating to high temperatures without losing their qualities. Such paints are used for painting highly heated surfaces( fireplaces, stoves, etc.).

    Thermal insulating coatings are used to reflect heat from the surface. Due to the formation of a special film, a screening coating arises, so that the room will not be as hot as it could be.

    Soundproof plaster

    You can provide noise insulation not only through the use of paintwork materials, but also due to noise insulation plaster. The composition of the plaster includes special components, the presence of which provides isolation from sound effects. It's about fillers in the form of small 5-millimeter granules. Claydite or pumice is the most commonly used material for granules. In this case, the granules are of low weight, since they have a hollow structure.

    Aluminum powder can also be added to the soundproofing composition. When such a powder passes through a drying step, gas is released from it, thereby ensuring the porosity of the material. The loose structure allows to delay the propagation of sound, since waves repel from very small particles.

    Please note! There is an incorrect opinion about the inability of plaster to act as a soundproofing. In fact, the plastered surface can extinguish a significant part of the sound wave, but only if the composition was applied in compliance with the technology.

    It is not recommended to paint the plastered wall with dense paint and varnish materials, such as enamel, since such actions result in the loss of a significant part of the soundproofing properties. The fact is that thick compositions fill the small pores of the plaster, which negates all the advantages of the porous material. In addition, do not cover the plaster with wallpaper, as the glue( viscous substance) also clogs the pores.

    Plaster is environmentally friendly material, therefore it can be used even in children's rooms. In addition, the relief plastered walls look very decorative, so they are pleasing to the eye and can, besides the utilitarian function( noise protection), play the role of decorating the interior.

    Application of plaster

    Before applying acoustic plaster, it is necessary to thoroughly prepare the surface. To do this, the wall needs to be leveled, remove dirt and dust from it, and apply a primer.

    Please note! The primer will better grasp the wall, if you add a ten percent lime paste.

    When the primed surface dries, plaster can be applied. It is important that the surface after plastering remained flat, and the layer of material did not exceed 2-3 centimeters.

    If it is likely that the working day will end faster than the entire surface covered with acoustic plaster, it is recommended to make a layer 1/3 thinner than necessary. In this case, the work will continue with the application of a new overlap layer. If you immediately make a uniform layer and do not complete the work, then in the future there will remain noticeable ugly joints.

    When plaster is applied, it is not recommended to do the grouting of the layer. Instead, it is better to treat the surface with a half-hammer. If there are walls painting in the plans, it is recommended to use only water-dispersion paintwork: although the application of paint is undesirable at all, but water-based paints are least harmful to the soundproofing qualities of the material.

    Noise isolation paint or plaster alone can not completely protect the premises from noise, as in this case a set of measures is required where a number of materials are used. However, as an additional measure, the noise insulation composition, of course, will improve the sound insulation performance.
