How and with what to paint a metal grill? Top 6 best paints

Why paint the grill

Is it necessary to paint at all?

My great friend, Captain Obvious, shared advice when it’s definitely not necessary:

• the kebab maker is welded from stainless steel or cast from cast iron - you will never wait for them to rust;
• the steel has been subjected to oxidation - there is already a protective film on the surface;
• you bought a light roasting pan made of very thin metal - you shouldn’t waste time and paint, which will crumble during the first heating when the walls “lead”.

Heat and weather protection

The walls, as well as the bottom of the brazier, come into contact with an open fire, hot coals and are heated from 650 to 1500 °. In addition, water gets into the brazier, the metal rusts, and the brick is destroyed. Without a protective coating, the metal will burn out within a couple of seasons. And it doesn't look very good. Good paint will protect against these problems and even decorate the barbecue.

Firewood gives a much higher temperature than coal or briquettes

Which manufacturer to choose

Today barbecues are very popular. They are produced not only by specialized companies, but also by professionals at home. The main material for their manufacture is steel sheet. With the help of high-quality fireproof paint, it is possible to extend the life of your barbecue much longer. The grill is exposed to open fire for quite a long time. After the cooking process is completed, the metal begins to cool, and with very frequent thermal exposure, corrosion can form. Today, the construction market offers a huge selection of heat-resistant paints for barbecues from both domestic and foreign manufacturers. We invite you to study the most famous of them.

Company Bosny

Heat-resistant Bosny enamel is made on the basis of modified alkyd resins with the addition of styrene. Also one of the components is microparticles of tempered glass, this provides a very reliable barrier to moisture. The drying time of this paint is short; it can be applied to the surface immediately without opening it with a primer, and it can also be painted on structures with rust without pre-treatment.

DuraCoat Company

DuraHeat 2.0. – is a heat-resistant paint for iron structures. It can withstand heating up to +1 thousand degrees. This paint is made on the basis of modified silicone resin and special pigments that do not lose their properties even under high heat. This enamel perfectly protects the metal surface and at the same time is able to retain its color. This paint can be used to paint not only barbecues and fireplaces, but also heating boilers, boilers and the like.

Thermika company

Heat-resistant paint Termika KO - 8111 is used when painting metal products and other surfaces. Able to withstand heating up to +600 degrees. The universal painting material is produced in a wide range of colors, thanks to which it is possible to choose a shade that suits the interior. This paint can protect the surface not only from overheating. It is oil and acid resistant.

Certa Company

Certa heat-resistant paint is designed to provide anti-corrosion and fire-resistant protection to metal surfaces and other types of materials. Just like the previous paint, it can protect the metal from the influence of chemicals and from overheating. Paint of this type can not only withstand heat up to +900, but also frost down to -60. This painting material is intended for painting concrete and reinforced concrete products, chimneys, engines and the like. When painting with this paint, you get very good protection from flames and rain, but at the same time the vapor permeability of the coating is maintained.

Tikkurila company

Tikkurila heat-resistant paint is available in two options: black and silver. The silver-colored paint is made on the basis of aluminum powder, this makes it possible to withstand heating up to +900 degrees, this paint is designed to protect the metal elements of barbecues and stoves from the effects of the external environment. This paint can be used both inside and outside the building.

Heat-resistant black enamel is designed to process structures that are exposed to temperatures no more than +400 degrees and can be used both inside and outside the building.

Elcon Company

Elcon heat-resistant paint is an anti-corrosion enamel that can withstand temperatures up to +800. And also frost down to -60 degrees. Once the enamel dries, it does not emit toxic substances and can be used inside the building. This paint is very popular when painting barbecues. It can be used to paint concrete structures, brick and many other types of material.

How to paint a barbecue: paints for barbecue

Regular coating fades due to high temperature. The paint coating will have to work in extreme conditions and come into contact with food; the requirements for it are quite strict.

There are quite high requirements for paint for painting barbecues:

• withstand temperatures from 600 °C - do not crack, do not melt, do not burn;
• distribute evenly over the metal, leaving no free areas;
• do not enter into a chemical reaction with metal at normal temperature, as well as heating;
• do not release harmful substances when heated or exposed to water.

Kinds

Grill paint is the most common choice. Pros: resistant to high and low temperatures, changes, humidity, easy to apply. Enamel is stable in a limited temperature range, but looks more impressive. Suitable for external parts that are not in direct contact with fire. The varnish creates an additional protective coating and enhances its thermal protective properties.

Temperature subtleties

Based on the temperature for which the coating is designed, it is divided into 3 types:

• high-temperature - can withstand temperatures of 200-600°. Will not withstand contact with a heated surface;
• heat-resistant - designed for temperatures of 500-1000°, can withstand rapid and spot heating, but can crack from fire;
• fire-resistant - withstands more than 1000°, contact with flame.

All compositions that can withstand heating above 200° are called by the general term - heat-resistant. The temperature at which heat-resistant barbecue paint retains its properties is indicated on the packaging.

Heat-resistant paint for stoves and fireplaces on metal
Another type of paint coating belongs to the heat-resistant class - fireproof. Unlike fire-resistant, it does not withstand high temperatures, and upon contact with a flame it swells. Its task is to stop a fire if it has started. Therefore, fire-resistant paints are not suitable for barbecues.

Choosing the right consistency

Liquid paint coating is a simple and convenient option. Less common are powder coatings for metal, aerosols. Each has advantages and disadvantages.

How to paint a metal grill and how to choose quality paint

Heat-resistant acrylic and organosilicon compounds are suitable for barbecues. Acrylic is available in liquid and aerosol form, is easy to apply, does not crack, and does not bubble from fire. It works at temperatures up to 800°, but from prolonged contact with open fire it loses its beneficial properties.

Organosilicon paints are only liquid. They provide reliable protection against fire and can withstand temperatures up to 1000° for 3-4 hours. They take a long time to dry and do not produce such a variety of colors as acrylic.

Common colors are black, gray. Soot, dirt, and coal marks are invisible on them.

The color of the coating does not directly affect the thermal protective properties. However, black coatings are produced that can hold temperatures of 600, 800, 1000°, and, for example, pink or red - only up to 500-600°.

Popular brands (Russia, Ukraine, Belarus):

• Kudo;
• Certa;
• Bosny;
• Decorix;
• Veslee;
• Elcon;
• Grog.

These brands offer paints, enamels, and varnishes of any color. The most popular consistency is an aerosol can. It takes two cans of 600 degree aerosol paint to cover a barbecue from a 50-liter gas cylinder.

Despite the higher cost, heat-resistant paint for stoves and fireplaces marked 700 degrees has proven to be much more economical. Half a 350 g jar is enough to cover the body twice. It is also more resistant to fire during prolonged use of the kebab grill.

Protection of brick structure

Nowadays, it is fashionable to make not just metal barbecues, but brick or stone braziers. In addition to the fact that it is made of fire-resistant bricks, heat-resistant impregnation will not harm it, plus it will help protect it from bad weather. The treated surface is easy to clean from soot, grease and soot with your own hands.

A cheap option would be to use KO 85 varnish, but it can crack due to frost. An option that combines price/quality combination would be the use of impregnation for stoves and fireplaces. This composition is not afraid of frost because it contains an oil component. The downside is the need for re-processing every other season.

Another practical composition is a silicone water repellent for ovens. The mixture is endowed with water-repellent and antifungal characteristics and perfectly protects brick walls from grease. Moreover, it retains all available properties even at high temperature loads.

Tools and materials

Tools needed for work:

• brush or sandpaper to clean the surface;
• acetone or any liquid containing it;
• rags for working with acetone;
• primer;
• dye;
• brush, backing;
• gloves;
• respirator.

Surface preparation

Painting begins with surface preparation. This step cannot be skipped: the color will lie unevenly, and corrosion will continue to damage the metal. Work outdoors in warm, dry, windless weather or indoors with good ventilation. The face, hands, clothing, and surrounding objects are protected with cloth, film or paper.

The collapsible grill is completely disassembled. Elements that do not come into contact with the fire - a thermometer, wooden or plastic handles, an additional table - are removed or covered with protective tape.

The next stage is cleaning the metal with a brush or sandpaper. Completely remove dirt, soot, traces of coals, and surface rust. The completely cleaned surface is degreased with acetone. Allow to dry. If a primer is used, it is applied and also allowed to dry.

The grill is painted only on the outside. There is no need to paint the interior surfaces - fire-resistant paint should not come into contact with food. Soot accumulates inside the kebab maker in any case, and the aesthetic effect of painting is minimal.

Painting the barbecue

Painting with heat-resistant paint - aerosol from a spray can:

1. Prepare the barbecue.
2. Shake the can.
3. Spray the product from a distance of 20 cm.
4. Each layer dries in 30 minutes.
5. Apply 2-3 layers.
6. After a day, light it and leave it to burn for 15 minutes.

Painting with liquid paint:

1. Prepare the barbecue.
2. Mix the paint.
3. Apply the composition with a brush.
4. Allow the paint to dry for at least an hour.
5. Apply another layer.
6. Burn.

The layers must be applied in a thin layer to avoid peeling.

Useful tips

For better results, we suggest using some tips. Then the result will please the eye for a long time:

• Paint using an aerosol, preferably in calm weather.
• The grill needs to be painted from the outside.
• After cleaning the surface from dirt, you can wash it and let it dry thoroughly.
• When painting, it is necessary to create such that when drying, dust and foreign particles do not fall on the surface. The result of this coloring may be disappointing.

In conclusion, we can say that the process of painting a barbecue is not as tedious as it seems. But it must be approached carefully. It is necessary to choose a suitable paint that meets all basic requirements. Next, prepare the surface to be treated. Apply several layers, first allowing them to dry thoroughly. That's all! Follow the process technology so that the grill does not deteriorate or rust.

DIY heat-resistant paint for barbecue

Heat-resistant paint based on liquid glass is very easy to make with your own hands. Simply mix the ingredients in a plastic bottle and shake well.

Liquid glass is a heat-resistant material that is used for low-cost metal coating. The simplest composition is 200 g of liquid glass and 10 g of silver powder - serebryanka.

They also paint the outside in 2-3 layers. Each layer dries for 10-15 minutes. The composition must be applied immediately after preparation.

Burnishing the grill

An alternative to painting a metal Dutch oven is bluing. Another name is blackening, chemical oxidation. For work, caustic chemical compounds are used - a combination of caustic soda, sulfuric acid and laundry soap.

Sequencing:

1. The surface is thoroughly cleaned of rust.
2. The parts are immersed in a container with sulfuric acid for 5 minutes.
3. Dissolve the soap in water and bring to a boil. The parts are immersed in the solution for 10 minutes.
4. The caustic soda solution is heated to 140°. The parts are in it for 1.5 hours.
5. Then rinse with running water.

Work only with gloves, respirators, and protective clothing.

The result of blueing a barbecue at home is black metal that does not rust or burn.

Types of mixtures for metal

Since manufacturers produce their products in different forms, everyone can choose their own option for independent use. At the moment I know these types of paints:

• Liquid mixtures that are packaged in containers and are immediately ready for use
• Aerosol cans
• Powder

Thanks to aerosol cans, application to the surface becomes very simple, but remember that they are best used for small painting objects. The price of such mixtures is much higher than other analogues due to the complex manufacturing and components in the composition that allow the paint to dry quickly.

But powder paint is used in industry. It is applied to the part and then baked in an oven, forming a high-quality coating.

While choosing the necessary mixture, I came across the requirements that heat-resistant paint should have:

1. Low electrical conductivity
2. The composition must be resistant to chemical influences. Due to the negative influence of the environment in which the material is used, its properties may decrease
3. Abrasion resistance
4. Should not emit harmful fumes and easily tolerate sudden temperature changes

How to paint a brick grill

The porous structure of the brick absorbs dirt, soot and dust; it is difficult to clean the stove, and over time it loses its appearance. Therefore, the new brick hearth is painted with heat-resistant paint. Outdoors and in the gazebo, the coating protects the barbecue from humidity and temperature changes that destroy the brick.

Organosilicon compounds, acrylic and alkyd paints are used for work. The latter produce bright colors, but are not sufficiently resistant to heat. Only the outer surface is painted: the walls of the firebox and the chimney.

Common brands:

• Elcon;
• Decorix;
• Kudo;
• Ecoterra;
• Prestige.

Popular colors are natural brick, red copper, gold, red, white, yellow. An ancient recipe for heat-resistant coating is a mixture of egg yolks and milk in equal parts. The components are mixed until smooth.

Is this really necessary?

There are different models of barbecues. Some of them are permanently installed outdoors, exposed to wind and rain in any weather. Other structures can be disassembled and stored in the utility room. In any case, the grill is subjected to heavy loads from heating and the action of the surrounding air, which often contains a lot of moisture. The advantages of coating metal with heat-resistant paints are obvious and are as follows:

• the layer protects from drops of fat, meat juice, and moisture;
• at high temperatures, the formation of cracks and defects is eliminated;
• The safety of the composition guarantees the absence of harmful fumes.

You can paint the grill at the very beginning, before installation, or subsequently, during a pause between uses. Both solid metal or brick products and collapsible structures can be processed.

Operation results

When properly applied high-quality heat-resistant paint, the metal structure does not burn or rust. The paint lasts 4-5 years. With active use, it lasts for 2-3 seasons, depending on weather conditions. To make a metal kebab maker last longer, it is covered and stored in a dry place.

The exterior brick barbecue is repainted every season. In winter, due to changes in temperature and humidity, the coating cracks. Before applying new paint, the old layer and dust are removed with a brush.

Coloring will definitely extend the life of the kebab maker. And you already know how to paint the grill.

Processing of products with non-metallic components

Combined structures, in which a metal brazier is used in tandem with a brick casing, also require additional protection. Heat-resistant and moisture-resistant varnishes can be used here; the only vulnerability is their inability to withstand low temperatures.

Fat impregnation based on an oily substance exhibits excellent frost-resistant properties. Such a solution is not afraid of temperature changes, but during operation it gradually becomes thinner and needs regular renewal.

Primary requirements

Before deciding how to paint a metal grill, you need to determine the requirements for the composition and type of paint. Here's what to consider:

• The paint should provide good protection against rust, temperature changes and exposure to precipitation.
• The composition should not release harmful substances during heating.
• When using heat-resistant powder paint, the surface is well protected from melting, as it becomes fire-resistant.

Heat-resistant paint ensures complete safety for health. This allows you to paint the structure not only outside, but also inside. Heat-resistant paint is easy to apply to metal surfaces. But with frequent painting on the inside, it is difficult to achieve the desired result.

Metal paint has a dry or liquid consistency. When using a liquid composition, the surface can be pre-treated with a primer. The dry mixture, presented in powder form, requires placement in a special oven. It is used for painting stoves, chimneys, fireplaces, barbecues and barbecues.

A barbecue made of stone or brick can be additionally protected with fire-resistant varnish. It is resistant to precipitation and elevated temperatures. If you plan to wash the surface, give preference to waterproof acrylic varnish.

Results

Paint the grill with heat-resistant paint

I want to say that the process of painting the grill was not difficult at all. Preparation does not take so much time, and the area is not so large that you need to put it off “for later.” The main thing is how the end result will look, because it is much more pleasant to invite friends to barbecue on a beautiful grill, and not on a rusty structure. Choose your paint carefully and read the instructions for its use before you start using the material. Proper preparation of the metal and compliance with the temperature conditions during painting will allow you to not think about updating the appearance of your roaster for many years

Materials and tools for painting

For high-quality painting, you will need to purchase not only paint, but also tools, as well as additional materials. Heat-resistant paint, unlike regular paint, does not require a primer, so you can do without it.

The tools required for application depend on the type of coating. For liquid compositions you will need a brush or roller, an aerosol is sprayed directly from a can, and powder paints require the use of a special sprayer. In addition, you will need newspapers to cover the surface around the grill and protective equipment - gloves and a respirator.

A drill with a special attachment will speed up the process of cleaning metal

When preparing the surface of the fryer, you also use:

• sandpaper;
• a metal brush to clean off the remnants of the old coating and rust (if the welding of the barbecue was completed recently, such treatment will not be required);
• degreasing solvent;
• washing powder dissolved in water.

Let's look at the technology for applying each type of paint, as well as alternative methods for processing a metal barbecue in more detail.
