If you have made a brazier or purchased it in a store, then sooner or later you will face the question of which paint to choose for protection. If the steel structure is operated outdoors, it will be constantly exposed to fire and atmospheric phenomena. If the surface is not protected, it will rust rather quickly.
Composition requirements
Paint must meet certain requirements, it protects the structure when exposed to fluctuations in temperature, humidity and precipitation. It is important to purchase a paint that will have the qualities of fire resistance and will not melt when exposed to fire. Among other things, the composition should not emit harmful substances with regard to the application and operation phase. Heat-resistant mixtures are able to withstand temperatures up to 800 °. The application is quite simple, such paints are usually harmless to he alth, they can be used to paint not only the outer, but also the inner surface of the product.
Varieties of heat-resistant paints
Barbecue paint can be one of several varieties. Having visited the store, you can find enamel coatings that are produced under the markings KO 8101 or KO 8111. On sale you can find heat-resistant paints of the KO / 08 and KO / 815 brands, as well as an organosilicate composition, OS 12/03 can be distinguished among the latter. A fairly popular solution due to economy is heat-resistant varnish KO-85. But it has one drawback, which is expressed in the possible appearance of cracks when exposed to low temperatures. You can also choose a resistant impregnation, which contains different oils that cope well with low temperatures. However, you should be prepared for the fact that such impregnation provides for the need for periodic updates. If you choose a barbecue paint, one of which was described above, then it will be able to withstand temperatures up to 500 °. By composition, such mixtures are resistant to high humidity and protect the metal from destruction.
Acrylic paints
Acrylic heat-resistant paint for barbecues is more popular because it is ready to endure temperatures up to 650 ° C. During operation, the layer can be briefly exposed to temperatures up to 800 °C. In this group of products, aerosol cans are in the lead, the main advantage of which is considered to be quick drying. It is important to remember that such paint should be stored under the recommendedmanufacturer's conditions, otherwise it may take a long time to dry after application.
If you will use acrylic paint for the barbecue, then before applying it, you do not need to prime the surface, but do not forget about the treatment of areas that have been subject to corrosion. The resulting layer will endure the effects of s alts and oils. After reviewing the assortment, you can choose heat-resistant paint for metal for barbecue in different colors. The most popular of them are: black, gray, brown, and also silver.
Overview of features of powder heat-resistant paints
Powder formulations differ in application technology. Dry paint should be sprayed onto the surface and then exposed to high temperatures. At the time of sintering, the composition acquires the required operational qualities, including heat resistance. An example is powder paint brand S54, which is made on the basis of silicone. This composition is specially designed to protect the surfaces of stoves, barbecues and barbecues at home. But in everyday life it will be difficult to use it, since it will require the use of a high-temperature drying chamber.
Classification of heat-resistant paints
If you need paint for barbecue, then you need to understand the classification of these compositions. They are conditionally divided into categories, among them: areas of use, temperature conditions, composition, as well as other factors. For example, for domestic use, compositions are used that are designed to work in a temperature range ranging from 80 to 100 ° C. They can be made on acrylic or alkyd resin. With their help, it will be possible to form a monolithic protective layer. If we are talking about temperature conditions ranging from 100 to 120 ° C, then it is best to prefer paint based on epoxy resin. On sale you can find one-component paints that are intended for operation at temperatures from 200 to 400 ° C. Among the ingredients are ether epoxy resins and ethyl silicate. For a temperature range that reaches 750 ° C, it is best to use the mixture in spray bottles. For conditions where the temperature rises above 700 °C, it is better to use a mixture based on silicone resin.
More about labeling
Heat-resistant paint for barbecue should be marked with an alphanumeric designation. If you saw two letters "KO", then this indicates that you have a paint based on an organosilicon binder. The letter is followed by numbers, the first of which indicates the purpose. Thus, the figure eight speaks of heat resistance. The second and all subsequent digits indicate the catalog number of the development. Before purchasing, it is recommended to familiarize yourself with the purpose of the composition. Thus, KO-811 is used for aluminum, steel, titanium surfaces that need corrosion protection. These enamels are good because their application is allowed at low temperatures. Eventuallyit is possible to obtain a coating that is environmentally friendly, heat and moisture resistant, as well as resistant to alternating heating and sudden cooling. As the temperature rises, the coating becomes even more durable.
KO-813 is a composition that is used for protective painting of metal surfaces exposed to temperatures ranging from 60 to 500 ° C. It is noteworthy that this heat-resistant paint for barbecue has anti-corrosion characteristics, is not at all afraid of high humidity and sudden temperature fluctuations. If it is necessary to protect surfaces that are exposed to temperatures up to 400 °C during operation, then KO-814 should be chosen. The resulting coating has a high resistance to s alt solutions, petroleum products and mineral oils. This composition is universal, as it can also be used for painting steam lines with hot steam. KO-8111 is a mixture that can be used to paint metal structures heated up to 600 °C. It is resistant to aggressive environments.
What do you prefer - enamel or paint
If you still have not decided what paint to paint the brazier, then you can consider the quality of enamels and paints. After applying the first, an opaque hard film forms on the surface, which is able to protect against high humidity, but not from the effects of open flame. When comparing heat-resistant enamels and paints, it should be mentioned that the former are more elastic, have high decorative properties,create a more durable coating, and their application is allowed even at sub-zero temperatures. However, the paint for the barbecue (1000 degrees) will not ignite if it is directly affected by the flame, which cannot be said about enamels.
Conclusion
Metal paint for barbecue should also be selected by the manufacturer. For example, Termika has been manufacturing similar formulations since 2007. The products of this supplier are confirmed by certificates, and the approximate cost will be 142 rubles. per kilo.
You can choose Dufa brand heat-resistant paint for metal for barbecue, which costs more - from 400 rubles, but allows you to smoothly distribute high temperatures over the painted surface, eliminating overheating. The advantage of enamels is the absence of aromatic carbohydrates, which allows the use of the composition indoors.
