Heat-resistant paints for stoves and fireplaces: an overview of popular heat-resistant compounds

Features of packaging and application of high-temperature mixtures

Coloring compositions are divided according to the method of packaging:

1. Liquid. Products are found in various containers (jars, buckets and barrels). The appropriate option is selected depending on the scope of work. Each variety has instructions for use with acceptable temperatures.
2. Powder. Such paint requires the use of special equipment, as well as certain experience.
3. In cans. This is a modern option that significantly facilitates and speeds up the work, there is no need to use additional equipment.Such compounds are produced with different levels of heat resistance, all information is placed on the label. Great for minor repairs or touch-ups. Due to spraying, even difficult places can be painted.

The compositions are also divided depending on the tool used:

Brush or roller. This is a traditional option that is suitable for all types of liquid paint. The brush helps to reliably cover difficult areas. For example, welding spots need more careful treatment, which is difficult to achieve with a roller or spray.

Airbrush

Although this method is widely used, some care must be taken. For spray application, the paint must be of a more liquid consistency, which may cause a decrease in refractory properties.

Therefore, the diluted composition is laid in several layers.

Powder heat-resistant dyes require the use of a set of equipment: a special spray gun, spray booth and curing oven.

All types of compounds are applied to metal surfaces in the same way, it is important to carefully prepare the base. In contrast to the use of conventional compounds, special mixtures are used for priming and processing, which must match the selected heat-resistant product.

Thermal paint selection criteria

Fireproof paint for metal is suitable for surfaces that are operated in conditions of strong exposure to moisture and high temperatures. For example, it can be used for drying chambers, for stoves in a bath, heating systems. Heat-resistant enamels are recommended for the automotive industry - they are used to paint parts of the muffler, engine, calipers.

When choosing a paint, you must read the instructions, which indicate which surfaces the composition is intended for.

For coatings of surfaces that experience strong heating, heat-resistant, heat-resistant and refractory mixtures are chosen. Heat-resistant paints for metal are required to be used where the temperature does not exceed 600 degrees. They can process metal furnaces or elements of brick furnaces. But for equipment in the bath, it is better not to take them, since the surfaces there can heat up to 800 degrees. In this case, it is better to resort to heat-resistant paints that can withstand more substantial temperatures.

Refractory types are taken for painting elements operated near the fire. For other conditions, they are disadvantageous because of their high cost. High-temperature paints are suitable for moderate temperatures no more than 200 degrees. These include engine parts, heating radiators, pipes, seams of brick ovens.

Heat-resistant varnishes are suitable for temperatures of 300 degrees. If you paint a brick with such a varnish, it will acquire a bright and shiny surface.

Metal stove painting

It should be understood that there are several reasons when you can resort to painting a brick stove. So you can approach this issue from an aesthetic side, from a practical and for security purposes. As for aesthetics, a stove in a house is needed not only to heat the house and make it comfortable to be in it, but also to maintain the interior and create a special coziness. On the practical side, after the fireplace is painted, the heat output increases and the stove surface is leveled.

Note! From a safety point of view, thanks to staining, it is possible to prevent the appearance of microcracks on the brick and, as a result, prevent the ignition of the dwelling. There are several options for coloring the structure

You can do this:

There are several options for painting the structure. You can do this:

• enamel;
• oil paint;
• drying oil;
• heat resistant varnish.

oily oven paint heat-resistant - the best solution, since there is a large selection of colors, the paint is able to withstand temperatures of 600 degrees Celsius, it is guaranteed to protect the brick from oxidation, it has increased resistance and durability. In addition, it is easy to apply and does not require any additional priming from the outside. However, there are disadvantages in the form of an unpleasant odor, the presence of toxicity and prolonged drying.

Drying oil is a material that cannot change the color of a brick, but only slightly darken it. As for the positive qualities, this coating is reliable and safe. The only downside is the price.

Heat-resistant varnish - a coating that can improve the technical characteristics of a brick surface.

Note! The peculiarity in its use is that it can be diluted with gouache to get the desired color with a hint. Cast iron is a fairly strong metal, which is favorably able to endure prolonged exposure to high temperatures.

According to some sources, you can not resort to painting the metal, but it's better to do it. An excellent option for a cast iron stove is the use of water-based acrylic or polyurethane paint, which has already proven itself well.In addition, cast iron alloy can more favorably endure even violations during painting.

In addition, the cast iron alloy can more favorably endure even disturbances during painting.

The painting process itself looks like this. First, the surface is pre-cleaned with a metal brush. Next, oxidations are skinned with five percent sulfuric acid, and the mixture is washed off with a soapy solution. Then the metal is degreased with a solvent and covered with paint. This is the whole technology of staining. In this case, the painting of the metal furnace should be even. All corners with seams should be reworked as much as possible.

Note! If there is no desire to drip onto the surrounding elements of the oven, it is necessary to use cellophane with masking tape

Brick ovens

In the first case, the structure will be protected from moisture, will have good strength and durability. In the second case, the plastered and painted surface will be able to withstand high temperatures, and in the latter cases it will be able to give strength to the brick.

Features of the surface and enamel for painting

To paint the surface of the plate, you do not need to have special knowledge, it is enough to have basic information and take into account some features when painting on your own. But it is worth considering the fact that ordinary enamel is not suitable for painting the surface of a gas stove, since when exposed to high temperatures, such paint deteriorates and peels off very quickly.

You can paint the stove at the place of its installation, but, nevertheless, it is advisable to temporarily disconnect the device from the gas supply network.

First, let's deal with the type of surface of gas stoves. So, most often, in the manufacture of gas appliances, alloyed stainless steel is used. The metal has a high degree of resistance to high temperatures.

Such a surface is painted with a special enamel to protect the coating from corrosion and give the gas appliance a beautiful appearance.

Before you start painting the gas stove, you need to remove the old layer of paint. To do this, you can use a metal brush, sandpaper or a chemical agent. Only after that you can start painting the old surface.

Plain enamel or acrylic paint is not suitable for painting the surface of a gas stove. Since when exposed to high temperature, it will melt and burn.

The paint for the surface of the gas stove must be resistant to high temperatures and other destructive factors.

As a rule, enamels with the following properties are used for painting:

• internal stability. Such enamels withstand high temperatures well and do not break down in conditions of high acidity.
• external stability.Such protection is designed to protect the metal surface, enamel protects both from thermal loads and from chemical processes.

Such characteristics are necessary for long-term use of a gas appliance in aggressive conditions.

Heat-resistant paint is designed for painting surfaces that are exposed to high temperatures. This option is suitable for coloring do-it-yourself plates

To achieve the required level of stability, the enamel for the restoration of a gas stove must include the following elements:

• quartz sand;
• soda;
• feldspar;
• borax.

All these elements form a transparent mixture, to which some more components must be added.

To obtain the most effective paint for appliances that are affected by high temperatures, the following elements are additionally added during production:

• alumina;
• zinc;
• alkaline elements;
• titanium;
• lead.

All this composition forms a high-quality paint with high resistance to aggressive factors and gives a beautiful gloss to the painted surface.

It should be noted that enamels with the addition of cobalt and nickel oxides have better adhesion to the painted element. Such paint can be applied even on a surface that has not been treated with a primer.

How to paint the barbecue?

Repairing a barbecue grill requires careful preparation. You need to buy the right paint, tools, find a place where the whole process will take place.

Correctly paint the brazier in dry weather. At the same time, the air temperature can be almost any.This should only be done outdoors or in a well-ventilated area: most heat-resistant dyes have an unpleasant odor.

The choice of paint and the necessary materials

There is a wide range of heat-resistant paints available in hardware stores. When choosing such a product, preference should be given to compositions that can withstand a heating temperature of at least 600 degrees. Among the most popular heat-resistant paints, the leaders are:

• Tikkurila Termal. The mixture belongs to silicone paints. Withstands temperatures up to 600 degrees. Failure to comply with safety precautions during painting work can cause poisoning.
• Cetra. Aerosol dye in a can. The coating is resistant to heating up to 900°C. Belongs to the alkyd group.
• "Elkon". The paint is silicone. Withstands heating up to 1000°C. Suitable for painting sauna stoves, barbecues, boilers.

Regardless of the type of dye, before working with it, you must protect yourself from inhaling toxic fumes. To do this, you need to purchase a special respiratory mask. It is better to apply paint with a brush. The roller is used less frequently for this.

Another painting option is to immerse the device in a container with prepared dye. However, this method will not allow you to completely paint over the sides of the product, so you will have to paint the upper part with a brush.

How to prepare the surface for painting?

With your own hands, anyone can update the metal grill so that it does not burn or rust. Regardless of the type of dye, the product should be prepared before dyeing. To do this, clean off soot and soot from it, remove rust.It will take a very long time to do this manually, so it is better to use a grinder with nozzles in the form of brushes. The cleaned surface should be degreased with acetone or white spirit. Then the product must be dried.

How long does the painted surface dry and when can I use the barbecue?

The drying time of the painted brazier depends on what type of paint is used. Usually the paint is applied in 2-3 layers. Each of them should dry for at least half an hour. On average, already 10–12 hours after the end of work, the product can be safely touched by hands and, if necessary, transferred. You can fry kebabs on an updated device a day after it dries.

Types of heat-resistant paints for ovens

Dyes marked "heat-resistant" are classified according to the degree of maximum temperature they can withstand. Several main types should be distinguished:

1. Up to 80 degrees. Such a composition has the lowest degree of heat resistance. At temperatures closer to eighty degrees, they begin to deteriorate: crack and inflate. For devices that will run on wood fuel, this composition is not suitable, because the combustion temperature of the logs is much higher.
2. Up to 100 degrees. Such products are more sustainable. They don't fade or fade. They are used to color those parts of the heating product where water is located. After all, the boiling point of water is 100 degrees, so the dyes in this case will last a very long time. But it is not recommended to completely paint all oven surfaces with this coloring agent, as it may crack. On the packaging of products of this type, you can find the inscriptions "acrylic" or "alkyd". The most common aerosol forms of release.
3. Up to 120 degrees. High-temperature paint for this type of oven withstands temperatures even more. These are products that have polyurethane, epoxy or acrylic in their composition.
4. Up to 200 degrees. Such coatings can be applied to furnace parts that do not heat up much (blowing door). If you apply products of the fourth type to the entire surface or metal parts inside, it will begin to burn and quickly deteriorate.
5. Up to 400 degrees. These are ethyl silicates or epoxy esters. The composition of such products includes small metal particles, which help to significantly increase the resistance of the coating to heat and increase its service life.
6. Up to 650 degrees. Such products can be used to cover the entire surface of the oven. With strong heating, they will not melt or deform. Silicone, zinc and aluminum are added to their composition, which provide resistance and durability.

Algorithm for choosing a suitable tool

Knowing the properties, the recommended scope of high-temperature sealants of various compositions, it will not be difficult to make the right choice.

So, attention should be paid to the following parameters:

• operating temperature;
• environmental friendliness;
• brand name.

Temperature endurance. The indicator depends on the basis of the sealant - silicone or silicate. When choosing, it is necessary to compare the future operating conditions of the paste with the values ​​\u200b\u200bof the maximum allowable temperature.

For repairing fireboxes, sealing chimneys, combustion chambers, sealing cracks near doors and other furnace fittings, only a fire-resistant compound with a maximum allowable temperature is suitable

If you save money and purchase a cheaper analogue, then the components will simply burn out over time - the mineral filler will exfoliate and you will have to re-repair the heater.

Environmental friendliness. The composition should not contain substances that emit toxic volatile compounds when heated. Regular inhalation of such vapors adversely affects human health.

To protect yourself, it is better to refrain from buying goods from unknown manufacturers at a suspiciously low price. It is necessary to carefully examine the packaging - fakes often make spelling mistakes, and the text itself can be printed illegibly.

If you suspect a counterfeit, you must demand from the seller a quality certificate, an accompanying document. It is better to buy sealant in specialized stores or large construction markets.

Manufacturer company. Among the wide range of products, domestic and foreign companies won the trust of buyers: Moment, MasterTeks, Penosil, Kraftool, Alteco, Tytan, Soudal, Makroflex, etc.

What paint is better to choose for a stove or fireplace?

In order for the paint to retain its decorative qualities under the influence of high temperatures, special heat-resistant enamels are produced. They are designed not only to give the structure the required design, protect the surface from persistent penetration of dust and dirt into bricks, but also from high humidity, and they will protect metal elements from oxidative processes and corrosion. Basically, all heat-resistant coatings are produced in the form of a suspension, and heat-resistant varnishes containing silicon and silicone act as the base there.

Heat Resistant Enamel Cetra (up to 600 degrees)

Heat-resistant paints are available in cans or as a spray in spray cans.When painting stone surfaces, the paint is absorbed into the porous structure of the brick and forms a thin film on them, which becomes a protective coating.

In addition to their inherent protective qualities, heat-resistant enamels give the structures of stoves and fireplaces a special decorative effect and elegance - their walls become brighter and more aesthetic.

Stone ovens always have various metal elements that also need periodic painting. For them, heat-resistant enamels for metal are used, which are usually available in cans. They usually dry quickly and are easy to use in that they do not require additional painting tools such as a brush. To choose the right paint option, you must definitely study the instructions on the package, and find out for which material this heat-resistant enamel is intended.

Basically, the paints used for painting stoves and fireplaces can withstand temperatures up to 500 degrees, and some of them even more, up to 700 degrees. If we take into account that coal burning in the conditions of the furnace heats up to 850 degrees, then the inner surfaces of the masonry will have a lower temperature, and in this case the heat-resistant paint on the outer surfaces will not suffer in any way.

She is not afraid of high temperatures

For metal parts of the furnace, it is better to choose a heat-resistant anti-corrosion paint, for example, KO-8101 enamel. It will perfectly protect such surfaces that are operated under conditions of constant exposure to high and low temperatures in the range from -50 to + 650 degrees. Therefore, it can cover not only the details of indoor ovens, but also outdoor barbecue ovens.

Basic heat-resistant enamel Elcon KO-8101

We can say that there is a choice for every taste, and by mixing colors, you can get rich deep shades. The manufacturer gives a guarantee for the operational period of enamel up to fifteen years.

Heat-resistant organosilicon enamels KO-811 and KO-813 have high technological characteristics that meet all the requirements of paints for heating structures, both for brick surfaces and for metal. They are made on the basis of organosilicon varnish and are able to operate at temperatures up to + 450 degrees. Enamels are able to withstand external aggressive environments and protect surfaces from its influence. They are quite suitable for coating steel, cast iron and aluminum surfaces. These paints are available in a limited range of colors - red, green and black.

Enamel paint KO-813 is available only in silver color and includes aluminum powder. It can be used for painting not only metal, but also brick surfaces.This paint has excellent heat resistance, moisture resistance and excellent antiseptic properties.

Preparation for staining and methods of application

The surface is first prepared. The requirements for the surface to be painted are usually described in the instructions for the composition. Some marks are applied without preparatory work, but in most cases the following will be required:

1. The surface is degreased, cleaned of the old coating and salts.
2. Remove rust. No rust spots should remain, the metal surface should acquire a silvery color. For processing, use a wire nozzle on a grinder or ordinary sandpaper. You can use sandblast.
3. Then the surface is washed and dried. With the help of a solvent, a complete degreasing of the surface is carried out. After degreasing, wait six hours if the work is carried out in the air. In the room you need to wait a day.
4. Then a coloring composition is applied. There can be several layers of application, in which case it is better to apply them in different directions - this is how better processing is achieved.

Paint is applied to the surface in three ways:

Consumption directly depends on the method of application. If the composition is applied with a brush, then the consumption will be 10–40% more than in the case of an aerosol, while the durability of the coating will be approximately the same.

Before work, you need to carefully read the instructions and follow all the painting conditions: temperature, drying conditions, time intervals between applying a new layer. Then the paintwork will last for a long time, retaining its properties.

Aerosol paints in cans are designed for painting small parts and surfaces in hard-to-reach places.

These disposable materials are also used in decorative, restoration work, as well as for the manufacture of stencil drawings, graffiti.

They are made in the form of containers (paint cans) filled with gas and dye under pressure.

Universal paintwork material is available in a large color palette, which allows you to choose a shade for almost any room interior.

The paint protects the surface not only from overheating, but also from the effects of oils, chemicals and salt solutions, and so on.

Certa heat-resistant paint is used to create anti-corrosion and fire-resistant protection of surfaces made of metal and other types of material. As well as Thermal KO-8111, Certa protects the metal from exposure to chemicals and overheating.

The paint is able to withstand not only high temperatures up to +900˚C, but also low ones up to -60˚C. This paint and varnish material can be used to paint reinforced concrete and concrete, chimneys, engines and exhaust pipes, and much more.

The paint allows you to get a reliable protection of the surface from the effects of heat and precipitation, while maintaining the vapor permeability of the coating.

Tikkurila Heat Resistant Paint is available in two versions - black and silver.

Silver-colored paintwork material is made on the basis of aluminum powder, which allows the coating to withstand temperatures up to +900˚C, and is designed to protect metal elements of stoves, fireplaces and barbecues from heat and atmospheric influences. The paint can be used both indoors and outdoors.

Elcon Heat Resistant Paint is an anti-corrosion enamel that withstands surface temperatures up to +800˚C and exposure to low temperatures down to -60˚C.

The paint coating after drying does not emit toxic substances and can be used indoors. This paint is most in demand when painting fireplaces, stoves, chimneys and barbecues.

It can also be used for painting surfaces made of concrete, brick, stone, metal and other types of material.

Summing up

Heat-resistant paints can be applied in a wide temperature range from +40˚C to -15˚C, but it is necessary that the air humidity is within the normal range. Application of a heat-resistant paint coating is best done in several layers.

The second layer should be applied only after the first has completely dried.

When painting work, it is necessary to observe elementary safety precautions - painting is required to be carried out in a respirator and avoid open flames in the room where the paint is applied.

And it is worth noting once again that the treatment of the surfaces of the stove, fireplace or barbecue with heat-resistant paint allows not only to give them a presentable appearance, but also, thanks to the protective paintwork, to extend the service life.

And the choice of paint by manufacturer - domestic or foreign - depends only on your personal preferences and financial capabilities, especially since some Russian companies produce paints and varnishes that are in no way inferior to Western counterparts.
