Heat-resistant paints for barbecues - types and methods of application

Application of heat-resistant paint

Fireproof barbecue paints and wet painting solutions are suitable for objects exposed to high temperatures:

• barbecues;
• pipelines;
• ovens;
• grills;
• engines;
• boiler facades;
• barbecue and grills;
• steel structures;
• metal fireplaces;
• landing valves;
• hydrants
• chimneys of fireplaces.

Heat-resistant solutions make it easy to spray paint and control the painting process.

Composition of fire-resistant dyes

The main difference between heat-resistant paints for metal and conventional ones is that fire-resistant paints contain pigments based on substances that are resistant to elevated temperatures.

Most of these dyes contain up to 50% titanium dioxide. Which has a melting point of +1855 degrees and, when added to the paint, reliably binds its components into a homogeneous mass, preventing it from igniting.

Ferrous oxide is added to the mixture, which is not subject to decomposition at high temperatures, and, like titanium oxide, allows the components in the composition to be more tightly bound. Heat-resistant paint contains chromium oxide, which increases its viscosity and color stability when exposed to high temperatures.

The listed elements are combined using a liquid base, which may consist of synthetic or organic non-flammable substances. This composition is used to treat metal surfaces that can be heated up to +1000 degrees.

If it is necessary to paint metal products that will not heat above +200 degrees, then in this case it is possible to use high-temperature paints based on epoxy resin.

Scope of application

High-temperature paint for metal is used for painting:

• heating radiators,
• internal combustion engine parts,
• stoves, boilers, fireplaces and various outdoor cooking equipment.

High temperature colors can be used in production. For example, in the production of drying chambers, roofing materials or machine tools, and at home during the independent construction of fireplaces or stoves.

Regardless of the scope of application of high-temperature paint, it is necessary to know exactly what criteria are used to select a high-temperature paint composition.

How to choose the right one

Only correctly selected paint will allow high-quality painting of a metal element that is operated at elevated temperatures.

To paint a solid fuel stove, it is also necessary to use fire-resistant dyes. If you ignore this rule, then with significant heating, ordinary paint will not only lose its aesthetic appearance, but can also cause a fire.

When painting parts of stoves and fireplaces, it is necessary to determine whether they are made of non-ferrous or ferrous metal. What type of surface the paint composition is intended for is usually indicated on the packaging, so you should study it very carefully when purchasing the product.

One-component paints, unlike conventional ones, do not fade, but can withstand heat of + 400 degrees. By adding metal powder to heat-resistant paint, a high level of flame protection and high heat transfer are achieved, which creates a thermal barrier and fire protection.

Heat-resistant paints based on silicone resin have been created for painting metal barbecues. When painting metal with a thickness of 30-100 microns, the normal condition is + 650 ºC.

Variety of paints for painting Source gidpokraske.ru

Fire-resistant silicone paint does not melt at temperatures above 650 degrees and is often used in painting old barbecues.

Peculiarities:

• corrosion resistance;
• excellent adhesive properties;
• fire protection.

Thanks to its unique composition containing composites and heat-resistant glass, heat-resistant paint is resistant to temperature changes. Binder particles, special pigments and fillers determine the temperature range that requires attention to preliminary surface preparation and adherence to painting technology. If it contains zinc powder, the painted surface will withstand + 500 degrees. And if it contains titanium dioxide, then the maximum exposure rate is + 1000 °C.

Selection criteria and varieties

Heat-resistant paint for barbecues must meet a number of requirements, which are described in more detail below:

• The paint should serve as a complete and high-quality protection of the metal surface from rust and corrosion, thereby it will create a special protective barrier in the event that the installation is exposed to rain, snow, or if it gets very hot or cools down sharply;
• The selected composition must have a high level of fire resistance; such a substance, when applied and after drying, must perform well at temperatures reaching 800-900 degrees Celsius. In this case, the coating will not melt, deform, or emit harmful substances or unpleasant odors;
• Fireproof paint for barbecues should not only be non-toxic, but also not interact with other substances and elements.

Fireproof paint for metal for barbecues must withstand temperatures up to 900 degrees Celsius; you can find information about this from the manufacturer’s instructions included in the kit. It should also be noted that this composition is safe for human life and health, thus it can be used to paint both the external and internal surfaces of the barbecue. All toxic substances and elements previously present in the metal, due to the application of such a protective layer, will be completely blocked and will not enter the lungs and food.

If necessary, in the assortment of specialized stores you can buy heat-resistant paint for metal barbecues in both gray and black colors, on which dirt, soot and soot are less noticeable, and in less practical white. The consistency of the coloring composition, which can be powdery or traditional liquid, also plays a major role in the ability of application. The liquid composition is applied only to a pre-primed metal surface, and the powder composition only after it has been hardened in a specialized oven.

It also happens that barbecues are made of brick or lined with stone; such surfaces, just like metal ones, need proper and timely protection. In this case, not fireproof paints are used, but special varnish compositions that can withstand sudden temperature changes, strong heat, high humidity, and exposure to atmospheric phenomena. Acrylic varnish compositions, which are characterized by a high degree of moisture resistance, are very popular for painting brick and stone barbecues.

It is important to think about the quality of the varnish composition or paint if your structure is not portable, but stationary; such installations are located in the open air all year round. Thus, in this case, you can give preference to such a varnish composition as KO-85, it has a good level of heat resistance. However, for stationary structures made of brick or stone, it is best to choose paints and varnishes that not only withstand high temperatures and their sudden changes, but also have good frost resistance.

Such frost-resistant paints and varnishes consist of special protective oils, however, despite their high degree of efficiency, such coating must be renewed every 2-3 years.

Before you buy paint for your barbecue, you need to pay attention to the group of silicone varnishes and enamels, which include:

• Enamel coating of various brands, which are called KO-8101 and 8111;
• Heat-resistant varnish marked KO-08 and 815;
• Organo-silicate composite composition marked OS-12/03.

All the varnish compositions and paints described and indicated above tolerate heating temperatures up to 400-600 degrees and are characterized by good frost resistance, while they are intended not only for metal surfaces, but also for stone and brick.

You can also buy paint or varnish based on acrylic; such substances, like the previous ones, tolerate prolonged exposure to temperatures up to 650 degrees and can withstand temperatures reaching about 850 degrees for a short time. For convenience, many heat-resistant acrylic compositions intended for painting barbecues are in the form of a spray can, which allows the composition to be easily and quickly sprayed. However, when working with such forms, it is necessary to use a respirator and protective clothing.

The advantages of paint in a can include the fact that it has a long service life and after closing and there are residues in the can, it does not dry out and after shaking it is ready for use.

Before purchasing acrylic paint in a can, pay attention to the fact that such a composition is fire-resistant, tolerates heating temperatures up to 600 degrees, is intended for painting the required material, and is non-toxic.

It is important to pay special attention to already damaged areas of the grill, where rust or corrosion has already formed; they must be treated in a special way and only then painted. The assortment includes acrylic paint in cans of white, gray, black, silver, gold, crimson and almost any other shade.

Video description

This video shows what materials to gather for painting and how to paint a grill.
Many of these heat-resistant paints emit gases that are designed to minimize the spread of fire to nearby areas and surfaces. And other fire-retardant paints create a protective charred coating that covers the main material of the grill for a limited period of time. The choice of product and paint depends on the required level of safety and the material from which the surface is made.

Factors to consider when choosing fireproof paint

What factors need to be taken into account:

• intended purpose;
• compound;
• metal operating conditions;
• temperature Range;
• color stability;
• application characteristics.

Attention! Application characteristics should be the main factor when choosing heat-resistant paint for a barbecue. These coatings require a relatively thin film to remain intact at high temperatures without cracking.

What paint to paint a metal grill

Many barbecue lovers know that a good grill requires careful care. But at this stage, many people have a question: how to paint it? Which paint should I choose to protect against fire and aggressive environmental influences?

All questions have their own answers. You just need to arm yourself with patience. Read the suggested tips and go create a heat-resistant grill.

How to paint a metal grill - expert advice

Outdoor recreation is necessary for meaningful communication with friends and family.

Not only spend time together, but also cook together - what could be better? In a cozy gazebo you can place a barbecue area on the site of a private house.

Also, a summer kitchen with its fresh air and easy approach to cooking is quite suitable for this purpose.

In any case, no matter what place you choose for barbecue gatherings, the grill is an important part of the landscape for cooking meat and vegetables over a fire or coals.

High temperatures and moisture on overheated metal accelerate corrosion of the material and shorten the service life of the product, but timely painting can prevent this. Of course, not every coating can withstand such conditions, so before you go to the store for paint, you should find out what you can use to paint the grill and how to do it correctly.

Painting a barbecue in 5 stages

The grill can be painted with heat-resistant paint in 1 day in 5 stages:

1. Cleaning from contaminants, wash with water and detergents.
2. Dry and wait until completely dry.
3. Choose the optimal place, protected from rain and wind.
4. Paint the grill using paint on the outside. It is advisable to use an aerosol.
5. Checking the results and correcting errors.

It is necessary to paint in sunny weather, away from bodies of water and precipitation. Before painting, select paint, check the expiration date and functionality of the aerosol device.

Attention! Experts recommend using silicone and multipolymer enamels for painting metal barbecues.

Painting

Let's start painting. I describe it step by step.

1. Clean off the rust with a wire brush.
2. If there are small problem areas left, we treat them with sandpaper.

3. We wash the grill parts or, if it is a solid structure, the entire roasting pan in a soapy solution and quickly dry it. Place on prepared oilcloth or film.
4. Degrease the surface with acetone or another special compound.

5. Shake the paint can thoroughly. Spray the aerosol onto the surface of the grill from a distance of 20-30 cm, depending on the recommendation on the package.

6. Leave the painted surface to dry for 10-15 minutes, cover with a second layer of paint. It is advisable to spray the composition crosswise in the direction in which the first layer was applied. If necessary, we carry out the procedure a third time.

It is best to paint in moderately warm weather. The first time after applying a heat-resistant coating, I advise you to protect the grill from dust and debris, otherwise they will stick to the paint and remain on its surface.

Useful tips for using heat-resistant paints

When choosing black heat-resistant paint for a barbecue, you need to know the material of the surface to be painted. The special properties of different paints help protect not only metal coatings, but also concrete, brick, asbestos and plastered structures. The heat resistance of a coating is related to the maximum permissible temperature at which the dried paint retains its protective properties against weather influences for a long time. This information is usually found on packages and cans.

The color palette of heat-resistant substances also depends on the temperature range. For example, black, graphite and silver heat-resistant paints are suitable for painting barbecues and fireplaces. Gray and white heat-resistant paints are designed for piping and metal fireplaces. The service life of the protective coating depends on compliance with the application technology specified in the manufacturer's instructions.

What criteria are put forward when purchasing paint?

If you have been thinking about the question of what paint to use on a metal grill, now we will look at what criteria it should meet:

• The coating that will be applied to the grill must protect it from corrosion, damage due to changes in temperature, moisture, and if water gets on the metal when it is hot. Otherwise, there will be rust on your grill.
• The paint must have a high fire resistance coefficient and must not melt. Otherwise, the grill will simply burn out. Basically, paints are divided into two types - those that are designed for temperatures up to 500°C or up to 1000 degrees. This can be seen in the instructions.
• We absolutely exclude the possibility of releasing harmful substances when heated or reacting with other substances.

As already mentioned, thermal paint can withstand temperatures up to 1000°C. It is quite easy to apply to metal coating. These paints are absolutely safe for health, so they can also be applied to the inside of the grill. But this, as experience shows, does not give the desired result. Science has proven that harmful toxins are not released when surfaces are treated with such paints.

There are also many colors available, so you can choose any color you like. The most common is gray or black, because the soot that forms after using the grill is less noticeable.

There are also several types of solution consistencies; the main ones are liquid or dry. When using liquid, the surface of the grill must be treated with a primer. If you use a dry consistency, then first you need to harden the metal in a special oven. Heat-resistant paint is designed just for this - to be used when painting barbecues, stoves, fireplaces, and so on.

The paint for the barbecue does not have to be black or gray - show your imagination and originality!

If you make a fireplace or barbecue out of brick or stone, without metal, then you need to use a special fire-resistant varnish. Acrylic varnish, in turn, is very practical, since after using it, you can wash the surface with water.

Heat-resistant impermeable varnish is also a very good solution. It can be used on brick or stone structures. But if there are severe frosts, cracks may appear on the varnish. Ultra-resistant impregnations are especially popular. They contain oils that can withstand low temperatures. But in this case, as experience shows, such impregnations will need to be renewed after some time.

To achieve a positive result, 1-3 thin layers are enough. A thick coating provides reliable protection against corrosion, but reduces the temperature range. Therefore, you can use a specialized anti-corrosion primer and coat the surface of the grill with heat-resistant paint. Apply the composition with a roller, brush or spray, avoiding the appearance of stains and carry out the painting yourself in compliance with safety rules.

Popular brands in the coatings market

Timely application of heat-resistant compounds protects products and structures made of metal, brick and stone and extends their service life.

The most popular brands:

• Tikkurila . Two-color paint produced in Finland. Used for external and internal processing to protect metal parts, pipes, dampers, car mufflers.

How to paint and why won’t regular dye work?

The paint must be heat-resistant, i.e. withstand high temperatures (up to 600-1000 degrees Celsius), while not losing the aesthetics of appearance, not melting, not cracking, not flaming. To do this, special components are added to it, which give the coating protective properties when in contact with fire or other hot substances.

Conventional dyes do not have such advantages, so it is not rational to use them. When such paints are exposed to fire or high temperatures, the color of the coating will change. It may crack or completely come off the surface being treated.

Interesting: heat-resistant paints for metal are completely safe. When exposed to high temperatures, the dye does not release harmful substances. In this case, the coating remains the same as it was originally.

Applying paint

The painting process depends on what type of paint the grill will be treated with.

Composition so that it does not burn or rust

To ensure that the protective coating is pleasing to the eye and that the grill does not burn for a long time, you must adhere to the following sequence. Here's how to properly paint a grill at home:

1. Cleaning the grill. From dirt, rust and other contaminants. You can use special electric metal brushes or sandpaper. As a result, the surface should be smooth.
2. Cleaning with acetone or other substances. Helps degrease the surface.
3. Prepare the paint. Make sure you make the right choice. Stir to make sure the consistency is uniform.
4. Application using brushes or rollers. Mandatory use of protective equipment. First you need to read the instructions about the temperature conditions at which you can apply the paint.
5. Apply the paint in several layers, with mandatory drying for half an hour to an hour.

Processing with acrylic dye

It is very convenient, since it mainly comes in the form of an aerosol. Painting stages:

1. We clean the grill as in the description of the previous method.
2. It is necessary to shake the can well for 2 minutes.
3. The number of layers may vary, but the main thing is to let each layer dry from 30 minutes to several hours. It is better to spray the paint from a distance of 20 cm.
4. After the last layer of paint has dried, let the grill burn for 15 minutes.

Types of paints

Before using heat-resistant paint, decide on its type. There are two main groups of such compositions:

• Organosilicon enamels: varnishes KO08 and KO815, enamel coatings of the KO8111 and KO 8101 brands, organosilicate compositions.

• Acrylic paints with heat-resistant composition.

Organosilicon compounds can withstand temperatures up to +500 degrees. They protect painted surfaces from subsequent destruction. Such compositions are resistant to high humidity. And they can be applied not only to metal, but also to other surfaces of the fryers.

Acrylic-based compositions are used for effective and long-term operation at temperatures up to +650 degrees. With short-term use, these paints can withstand temperatures up to +800 degrees.

From the acrylic category, the most convenient to use is fireproof paint in aerosol cans. It is characterized by fast drying.

But all precautions must be taken, as these compounds are toxic. When using this thermal paint, you do not have to pre-prime the surface. All rusty metal must be thoroughly cleaned before painting.

Note! If you don’t know what paint to use, consider the expected operating conditions and the degree of heating of the grill.
