Kebabs are sacred. Without them, a picnic can hardly be considered successful, and a trip to the camp site will be boring, and evenings at the dacha will turn out to be empty. And no one will refuse to just have a good time. And in order not to lose the innocent barbecue pleasure, at a certain stage you should take care of how to paint the barbecue. Otherwise, pretty soon you will be forced to go to the store for a new one.
To paint or not?
Often, people believe that the brazier is strong enough to do without additional processing. However, do not forget that it is operated in rather harsh conditions - air, temperature, humidity … And if, moreover, it is never cleaned at least in an unheated room, the question of how to paint the brazier so as not to rust becomes especially relevant: rains and snows in a year will bring the "bonfire" to dust. However, even if you take the barbecue with you every time,it is unlikely that you store it in civilized conditions. Most likely, while it is not needed, it is lying on the balcony (it's good if it's glazed) or in the trunk.
If the hearth is made with your skillful hands, then you need to think about how to paint the brazier so that it does not burn and corrode, even at the stage of creating a drawing. Factory copies receive at least some protection during production, its manufacturer should take care of the homemade one.
How to paint the brazier: composition requirements
Guide to the selection of paint includes only three items:
- Anti-corrosion properties: when moisture gets on the surface, it should not get into the thickness of the sheet. Moreover, rust resistance should be complemented by the ability to withstand aggressive environments, primarily hot fat.
- Heat resistance. Moreover, it must be strengthened by resistance to temperature changes: often prefabricated barbecues are cooled with a bucket of water to speed up the process. The temperature index of the paint must be at least +500 Celsius, and it is better to exceed it.
- Sustainability. Do not forget that our hearth is intended for cooking. And the harmful substances released from the paint can in no way be considered seasonings.
Some beginners, having chosen what paint to paint the metal barbecue, carry out processing inside it. This is a pointless waste of materials and time - the working temperature in the "brazier" is so high that the protective layer will burn out anyway.
Varieties of colors
The list of how to paint a metal barbecue is quite long. Most popular with home craftsmen:
- Silicone enamels and paints.
- Varnishes with high heat resistance (codes KO/08 and KO 815).
- Temperature and moisture resistant enamel coatings named KO 8101 or KO 811.
- Silicate-organic compositions, of which OS 12/03 is a prominent representative.
The minimum temperature threshold for all of them is +500, the protective properties are very high, the compositions are suitable not only for metals.
Coloring with liquid compositions
How can I paint the brazier? Consistency compositions also vary. So far, liquid ones are most often used. The algorithm for their application is simple and has long been familiar to everyone. But if we are talking about a brazier that has already been in use, some clarifications will be needed.
First of all, the surface is carefully cleaned. Not only dirt, debris and dust are removed, but also clots of soot, and old paint, if present. It is most convenient to do this with a drill with a special nozzle, but you can use a metal brush or coarse sandpaper. Rust is also cleaned, if necessary, you can use its converter.
The next step will be washing with any detergent and drying, and the last preparatory step is degreasing with a solvent. Immediately before painting, the surfaces are treated with a primer purchased for a specific paint. Most often inhardware stores sell them in pairs. After complete drying, you can paint - with a brush, roller, remote control, or immerse in a bowl with the composition, if the hearth is collapsible or small.
Powder options
The construction industry also offers dry paint for the intended purposes. To paint the brazier with it, many consider it the best idea: the coating is as strong as possible and extremely fire resistant. S54 silicone-based powder paint received wide approval. When using it, soil is not needed, the dry mixture is sprayed over the surface, and the hearth is placed in a drying chamber or oven. This is the only difficulty when using dry paints: at home, they are only suitable for small or collapsible foci. But in production, this is the main way to create a protective layer on the grill.
Painting with acrylics
From the list of what to paint the brazier, acrylic paints have recently become more and more in demand. Firstly, they can withstand a temperature of +650 for a long time; does not harm the coating and a short-term rise to +800. Secondly, they do not require priming, which reduces time costs. Thirdly, it is convenient to work with them: aerosols are sprayed evenly and dry very quickly. The only minor inconvenience can be considered the need for protective clothing - gloves and a respirator. Moreover, if gloves can be neglected, then a respirator is not needed, inhalation of acrylic paint vapors is definitely not useful forhe alth.
When buying aerosols, pay close attention to the date of their release: if it is too old, the paint simply will not set. The same applies to the spray can you found in the garage or shed. It stood for a long time, and even open - throw it away without a doubt, otherwise you will provide yourself with work to remove the applied composition.
Preparatory work will be cleaning, including rust, followed by degreasing. The can is vigorously shaken for a minute, its contents are sprayed from a distance of 20 centimeters. The paint is applied in two layers, especially diligent people can put three, observing the drying time. Different manufacturers take from one and a half to three hours for this process.
Bluing as an alternative
If none of the options for how to paint the brazier appealed to you, you can go the hard way. Chemical oxidation is considered the most reliable protection against corrosion and burnout. True, you will need skills in working with hazardous substances and a well-ventilated area. Just in case, it’s better to work in the air.
The brazier is carefully cleaned; a container of sufficient size and chemically passive is sought. Sulfuric acid is diluted to a five percent concentration, the focus is immersed in it for five minutes. While it is aged there, a solution of laundry soap is made and boiled; the brazier removed from the acid bath is placed in it for ten minutes. The last stage will be an hour and a half boiling brazier in a solution of caustic soda. extreme caution, protectivegloves with goggles and a respirator!
Stationary barbecue
In country houses and dachas, a hearth is often built of stone or bricks. Despite the fact that the material is usually refractory, such a furnace also needs protection. The stone frame is covered with a heat-resistant varnish, which increases not only the refractory performance, but also the resistance to other negative influences. If you want to make it easier for yourself to care for the barbecue in the future, take acrylic waterproof varnishes. Their most democratic representative is KO-85, but keep in mind that it often cracks in severe frosts.
If you do not consider it necessary to increase the heat resistance of your hearth, at least take care of its durability. Brick and stone do not resist biological attacks and moisture very well. In order to help in this fight, use a silicone-based water repellent. The brazier fungus will not be terrible, the outer surfaces will acquire water-repellent properties, in addition, the masonry will be protected from penetration of splashing fat.
