Painting Painting Subtleties for Mangala

    Sooner or later, every mangaal owner faces the need to paint it in order to be able to protect it from adverse weather conditions and extend the life of the product. This issue is especially relevant for homemade, forged structures operated in the open air, or for ferry, with the emerging metal corrosion traces.

    The choice of coloring compositions should be approached with all seriousness, After all, they must ensure not only the protection and durability of the device, but also to meet all human security standards.

    Selecting paint

    In order not to endanger your health, it is better to give preference to special high-temperature compositions.

    They are required to meet certain requirements.

    • Paint should have a high refractority, the ability to withstand temperatures up to 1000 degrees, and at the same time it should not melt. Such a heat-resistant and fire-resistant thermocracy is more reliable.
    • When heated, it is unacceptable for the release of toxic and poisoning substances.

    • Unacceptably the occurrence of any chemical reactions when interacting with any materials used.
    • Reliable metal protection must be provided from any phenomena of a negative nature: a sharp change in temperature or humidity of air, rain drops or snow on a split surface.

    Heat-resistant paint, specially intended for staining ovens, fireplaces or mangals, satisfies all of the above requirements. Having special anti-corrosion components in its composition, it helps to ensure reliable protection of the metal. The composition will not harm the health, therefore it can be used both in external work and for staining the inner surface. Numerous laboratory studies have confirmed the lack of release of toxic substances during the operation of installations painted by such compositions.

    Most often, the owners are painted mangals in black or gray, so that soot and other contaminants are less noticeable. But if you want to do something unusual, bright and individual, the large color palette of the produced heat-resistant paints can help implement any fantasy. The consistency of such coloring compositions can be two types: liquid and dry powder.

    Liquid heat-resistant paints

    When using liquid paint, you must first treat the painted surface with a special primer. As a result, the best grip of paint with metal is ensured. In addition, the quality of the painted surface is improved, which provides greater reliability and durability of the coating.

    It should be borne in mind that the usual primer in this case does not fit. It does not have increased elasticity, which means that will crack in the process of operation.

    Dry powder paints

    The composition of such mixes add heat-resistant glass and some composite materials. Under the proper technology of their application, a resistant coating is created, capable of withstanding temperatures up to +1000 degrees on the Celsius scale.

    Such paints differ from all other ways to apply to the painted surface. Powder is evenly sprayed on the surface of the product, after which it is loaded into a special furnace, where the process of sintering paint under the action of high temperatures. As a result, it acquires special properties, including increased heat resistance. This method is more suitable for industrial staining, as it requires a special high-temperature drying equipment and stoves.

    Types of heat-resistant paintwork

    Currently, the range of heat-resistant paints produced by various manufacturers is small, since only a small amount of substances can protect the surfaces from high temperatures. Depending on the chemical composition, such paints can be divided into several species. The most popular of them are silicone and acrylic compositions.

    Silicon enamel and varnishes

    Designed staining and protection of metal surfaces, which during operation are exposed to temperatures from -60 to +500 degrees on the Celsius scale.

    These paints and varnishes have a number of features.

    • Present a mixture of solvent, dyes, target additives and varnish based on silicon-organic resin.
    • Protect metal from corrosion. Increase moisture resistance, increase resistance to acids, salts, oils and petroleum products that are part of the liquids for rapidly ignition.
    • Suitable for coloring of brick surfaces, concrete, asbestos cement and plaster.
    • Basic colors: black, gray, white, brown and red.

    If you want to improve the appearance of a brickwork of a street furnace or brazier, then the best recommendation will be the use of silicone enamel for this.

    One of the essential deficiencies is a very strong smell of coloring compositions. Therefore, it is best to work with these types of heat-resistant paints outdoors or in well-ventilated rooms with ventilation.

    Acrylic paints

    Special acrylic resin-based compounds are increasingly popular with consumers. This is especially true of the compositions produced in the form of aerosols. They are very easy to use, have increased efficiency, resistance to abrasion and short period of drying.

    Acrylic compounds freely withstand constant working temperatures up to +600 degrees on the Celsius scale and even their short-term increase of up to +800 degrees. It should be borne in mind that enamels acquire heat resistance immediately after the first warming up to temperatures from +180 to 220 degrees, if it lasts for at least 15 minutes. Before that, it is possible a partial shower of the colorful layer.

    Among the features of this type of paint coatings can be distinguished by several.

    • In addition to acrylic resin, there are fillers in the form of glass, mineral or aluminum powder, color dyes and additives with protective properties. As solvents, manufacturers use liquefied gases: propane, butane Light oil fractions. Due to this, the paint dries out for 10-15 minutes.
    • Acrylic paints have excellent grip with surface and black metals surfaces.
    • They are very easy to use, which allows you to do all the work on your own.

    The main minus of all aerosol paints, including high-temperature, is their light flammability and toxicity. Therefore, their use implies the use of protective clothing, gloves and respirator. And the work should be carried out with the strictest observance of all the rules of fire safety.

    Alternative Metal Protection Methods

    Another embodiment of the grill or mangala can be oxidation or moth binding. The technology of this process is to process metal solutions, alkalis and other reagents. As a result of this process, the upper layer of material changes its structure. A protective film appears on it, which not only updates the surface, but also additionally protects against destruction.

    Until recently, a similar method of processing metal products was available mainly using production equipment. Forged or welded brazier and now can be treated in this way only at an industrial enterprise. This process occurs in several stages and requires the use of a large number of chemical solutions and impressive capacities.

    If you are the owner of the collapsible design, it is quite possible to perform oxidation at home. Work is to apply to the metal surface of a special composition, under the action of which the color and properties of the material. The technology is somewhat different from industrial, but the final result will be almost the same.

    All special paints and varnish refractory materials are quite expensive. But the costs of their acquisition justify themselves in the process of operation or long-term storage of mangalls, grills, fireproof and other similar equipment. They help reliably protect the metal from the action of high temperatures, adverse environmental factors and the appearance of rust. The main thing when choosing paint for mangala – make sure that it meets all the requirements for the necessary properties and safety.
