The subtleties of the choice of paint for barbecue

Sooner or later, each barbecue owner is faced with 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 particularly relevant for improvised, forged structures used in the open air, or for braziers with the appearance of metal corrosion.

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

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

They must meet certain requirements.

• The paint should have high refractoriness, the ability to withstand temperatures up to 1000 degrees, and at the same time it should not melt. Such a heat-resistant and flame-resistant thermal paint is more reliable.

• When heated, the release of toxic and toxic substances is unacceptable.

• It is unacceptable the occurrence of any chemical reactions when interacting with any materials used.

• A reliable protection of the metal against any negative phenomena such as a sharp change in temperature or humidity, rain or snow on a red-hot surface must be ensured.

Heat-resistant paint specifically designed for painting stoves, fireplaces or barbecues, satisfies all the above requirements. Having special anti-corrosion components in its composition, it helps to ensure reliable protection of a metal product. The composition will not cause harm to health, so it can be used both in exterior works and for painting the inner surface. Numerous laboratory studies have confirmed the absence of toxic substances during the operation of installations stained with such compounds.

Most often, the owners paint the braziers in black or gray, so that soot and other contaminations are less noticeable. But if you want to do something unusual, bright and individual, a large color palette of manufactured heat-resistant paints can help to bring to life any imagination. The consistency of such coloring compositions can be of two types: liquid and dry powder.

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

It must be borne in mind that the usual primer in this case is not suitable. It does not have a high elasticity, and therefore will crack during operation.

Heat-resistant glass and some composite materials are added to the composition of such mixtures. At observance of the correct technology of their application, a resistant coating is created that can withstand temperatures up to +1000 degrees Celsius.

Such paints are different from all other methods of application to the painted surface. The powder is uniformly sprayed over the surface of the product, after which it is loaded into a special furnace, where the sintering process of the paint takes place under the action of high temperatures. As a result, it acquires special properties, including increased heat resistance. This method is more suitable for industrial dyeing, as it requires special high-temperature drying equipment and furnaces.

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

Designed to paint and protect metal surfaces, which during operation are exposed to temperatures ranging from -60 to +500 degrees Celsius.

These paint coatings have a number of features.

• They are a mixture of solvent, dyes, special additives and varnishes based on silicone resin.
• Protect metal from corrosion. Increase moisture resistance, increase resistance to acids, salts, oils and petroleum products that are part of liquids for fast ignition.
• Suitable for painting surfaces of bricks, concrete, asbestos cement and plaster.
• Primary colors: black, gray, white, brown and red.

If you want to improve the appearance of the brickwork of an outdoor stove or a brazier, then the best recommendation would be to use silicone enamel for this purpose.

One of the most significant drawbacks is the very strong smell of coloring compositions. Therefore, it is best to work with these types of heat-resistant paints in the open air or in well ventilated areas with ventilation.

Special compositions based on acrylic resin are gaining increasing popularity among consumers. This is especially true of formulations produced in the form of aerosols. They are very easy to use, have increased efficiency, abrasion resistance and a short period of drying.

Acrylic compounds freely maintain constant working temperatures up to +600 degrees Celsius and even their short-term increase to +800 degrees. It must be borne in mind that enamels acquire heat resistance immediately after the first heating to temperatures from +180 to 220 degrees, if it lasts for at least 15 minutes. Prior to this, a partial shedding of the paint layer is possible.

Among the features of this type of paint coatings there are several.

• In addition to acrylic resin, there are fillers in the form of glass, mineral or aluminum powder, color dyes and additives that have protective properties. Manufacturers use liquefied gases as solvents: propane, butane, light petroleum fractions. Due to this, the applied paint dries within 10-15 minutes.
• Acrylic paints have excellent adhesion to surfaces of non-ferrous and ferrous metals.
• They are very easy to use, which allows you to do all the work yourself.

The main disadvantage of all spray paints, including high-temperature paints, is their flammability and toxicity. Therefore, their use implies the use of protective clothing, gloves and a respirator.And the work should be done with the strictest observance of all fire safety rules.

Another option to protect the grill or grill can be oxidation or burnishing of the metal. The technology of this process consists in processing the metal with solutions of acids, alkalis and other reagents. As a result of this process, the upper layer of the material changes its structure. A protective film appears on it, which not only renews the surface, but additionally protects it from destruction.

Until recently, a similar method of processing metal products was available mainly using production equipment. Forged or welded brazier and now can be processed 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 containers of impressive size.

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

All special paint refractory materials are quite expensive. But the cost of acquiring them justifies itself during the operation or long-term storage of barbecues, grills, broilers, and other similar equipment. They help to reliably protect the metal from the action of high temperatures, adverse environmental factors and the appearance of rust. The main thing when choosing a paint for barbecue is to make sure that it meets all the requirements for the necessary properties and safety.
