Which fireproof paint for a stove is better - types, differences, rules of use. Heat-resistant paints for stoves and fireplaces: choosing the appropriate composition Heat-resistant paint for a brick stove

A lot of home craftsmen make their own sauna stoves. However, not only for the bath. In order for the stove to have an attractive appearance, it is advisable to paint it. Since paint not only improves appearance, but also protects the metal surface from splashes and reduces surface contact with oxygen, oxidation occurs more slowly.

Brick stoves are less often painted, especially when they are made of good brick. But in some cases, the brick begins to crumble - it has overheated or was unlucky with the batch. Cracks also often appear in the masonry. They are sealed with mortar, but in order to give a more presentable appearance, they are painted. For all these needs, high-temperature paint is required.

Features of choosing paint for the stove

You can’t paint a stove with simple paints: the highest temperatures they can withstand are 45−55°C. During the first fire, this coating will swell, change color before your eyes, bubble, and also spread “aromas” and smoke. Therefore, special compounds that can withstand elevated temperatures are clearly needed.

The degree of heat resistance required will depend on the type of oven. If it is a metal stove, then it can heat up more than 700-900°C: the temperature is higher in the combustion zone, but taking into account the design, the outer walls may not heat up so much. For the outer surface of the brick, increased values are not required - 300 °C is quite enough.

An important requirement is that the fireproof metal paint for the furnace must be suitable for interior painting. For sauna stoves, it is best that it also protects against high humidity.

Terminology of thermal paints for metal

Fire-resistant, heat-resistant and heat-resistant paints are suitable for painting surfaces with elevated temperatures. Fire retardants should not be used. Although the name is similar, the purpose of this paint is completely different: when heated to a certain temperature (about 150°C), it bubbles, blocking the access of oxygen to the structure, thus preventing its destruction. Quite a useful effect, but not in the case of a stove.

Application for different surfaces

In order to decide what paint to paint the stove with, you need to pay attention to what surfaces this composition is intended for. Often the scope of application is indicated on the packaging in large letters. For example, fireproof paint for metal. If the scope of use is extensive, then it is indicated in a smaller font, but it must be on the packaging, like the brand name. If this data is missing, refuse to purchase. Most likely, this is a fake, and the combination of high temperatures and dubious quality is dangerous to health.

In addition to temperature resistance, paint for a metal sauna stove must protect against high humidity. In this case, it will last longer.

Color selection

Heat-resistant paint is usually found in silver, gray and black. Other shades need to be looked for, but they also exist: red, white, blue and green. The coating can be glossy or matte.

Matte black thermal paint is common, however, some manufacturers have different shades and colors.

Manufacturing form

Thermal paints are produced in cans or spray cans. Accordingly, they can be applied from cans with rollers, brushes or sprayed using special equipment, and from cans they can be sprayed.

Heat-resistant spray paint, as a rule, has a volume of approximately 500 ml. Cans are usually packed in 0.4-5 kg. There is larger packaging in barrels and buckets.

Which is more convenient? It's a matter of habit. With skill, a more uniform layer comes out of the can. In this case, the consumption may be less than when using a brush or roller.

Features of painting a metal stove

For metal furnace Thermal paints that can withstand temperatures above 700 °C are required. Here are some paints, their brief descriptions and manufacturers.

All the above compositions can also be used for painting heating boilers, including potbelly stoves.

Surface preparation and painting

It is not enough to simply choose what paint to paint a metal stove in a bathhouse. It is still necessary to properly prepare the surface . Certain colors require special preparation, or do not require it at all, in which case the procedure is indicated on the package, but, as a rule, the following actions are required:

Each manufacturer specifies temperatures during which paint can be applied, how much time must pass before applying the next layer (if necessary) and under what conditions the paint must dry completely. It is very important to observe all this.

DIY thermal paint

There are very few homemade, proven compositions that can be used to reliably paint a metal stove. By and large, it is the only one: you need to add aluminum powder to the liquid glass and mix thoroughly. The result will be a silver color. During the first fire, the surface smokes very much, because after coloring it’s best heat the stove outside. No problems arise during subsequent use.

Painting a brick stove for a bath

Painting the outer surface of a brick sauna stove will not require increased heat resistance. The surface does not often heat up above 100°C. Only around furnace casting temperatures are a little higher. Therefore, heat resistance up to 300 °C is quite sufficient.

There are classic options for upgrading a brick stove. If the brick is ugly, then the stove is plastered, then whitewashed with chalk or lime mortar. In order to make the surface smoother, it is puttied after plastering, and to prevent clothes or hands from getting dirty, water-based emulsion is used instead of traditional chalk and lime. While the water-based emulsion dries, it smells unpleasant, but there are no odors in the future. Naturally, you can paint it in the color of your choice, or paint the stove with designs.

If needed paint metal elements brick oven, then purchase compositions from those that are suitable for metal ovens with a heat resistance of more than 700 degrees. First, the parts must be cleaned from rust, dirt and old paint to shiny metal. Then cover the surface near the door (as a rule, it is painted) with paper and you can paint. If you use heat-resistant spray paint, you will need to cover a larger area of the surface: one careless movement and the main surface will have to be repainted again.

If it is necessary to paint any elements, paint must be selected not only based on its color, but also taking into account its qualities and the properties of the surface being painted. If the metal surface is subject to corrosion, temperature changes and other negative influences, it is best to use heat-resistant metal paint, which, unlike conventional paint, will prevent the appearance of damage and cracks after painting the surface.

Requirements for properties and types of paint

Metal conducts heat well, so painting it requires special compounds that can maintain properties at elevated temperatures.

The main components of such paints are silicone varnishes, solvents, and pigments. Also, depending on the manufacturer, there may be other components in the composition.

The temperature at which thermal paint can be used for metal depends on the composition. Depending on the temperature conditions and components, it comes in the following varieties:

Alkyd or acrylic (up to 100 degrees, suitable for heating elements).
Epoxy (up to 200 degrees).
One-component ethyl silicate and epoxy ester (up to 400 degrees, sometimes metal powder is added to them).
Silicone one-component (up to 650 degrees).
Using heat-resistant glass and composite materials (up to 1000 degrees).

Heat-resistant paints for metal must not only withstand high temperatures, but also meet certain requirements:

wear resistance;
ensuring electrical insulation;
corrosion protection;
preservation of properties during sudden changes in temperature;
plasticity and strength;
good adhesion;
low toxicity;
resistance to various chemicals;
petrol resistance.

Criteria for choosing thermal paint

Fireproof metal paint is suitable for surfaces that are exposed to severe moisture and high temperatures. For example, it can be used for drying chambers, bathhouse stoves, and heating systems. Heat-resistant enamels are recommended for the automotive industry - they are used to paint muffler parts, engine parts, and calipers.

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

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

Fire-resistant types are used for painting elements used near fire. For other conditions they are unprofitable due to their high cost. High temperature paints Suitable for moderate temperatures no more than 200 degrees. These include engine parts, heating radiators, pipes, and seams of brick kilns.

Heat-resistant varnishes Suitable for temperatures up to 300 degrees. If you paint a brick with this varnish, it will acquire a bright and shiny surface.

Advantages and popular brands

Heat-resistant paint can be found both in aerosol cans and in cans, buckets and even barrels.

The advantages of such compositions include:

a high level of electrical insulation is an important point if you plan to paint metal products that transmit current;
protection against corrosion - thermal paint can reliably protect metal from moisture;
plasticity (when heated, the metal expands, the coating also stretches and does not crack);
resistance to aggressive environments.

Currently, there is a huge range of similar paints on the market, among which you can find an option for almost any occasion. Depending on the manufacturer, each of them has a specific composition, its own characteristics and features, as well as cost.

Preparation for painting and application methods

The surface is first prepared. The requirements for the surface to be painted are usually described in the instructions for the composition. Some marks can be applied without any prep work, but in most cases you will need to do the following:

The surface is degreased, cleaned of old coating and salts.
Remove rust. There should be no rust stains left, and the metal surface should acquire a silver color. For processing, use a wire attachment on a grinder or regular sandpaper. You can use sandblasting.
Then the surface is washed and dried. Using a solvent, the surface is completely degreased. After degreasing, you need to wait six hours if the work is carried out in the air. You need to wait a day indoors.
Then the coloring composition is applied. There can be several layers of application; in this case, it is better to apply them in different directions - this way, a better finish is achieved.

Paint is applied to the surface in three ways:

roller;
brush;
spraying.

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 comply with all painting conditions: temperature conditions, drying conditions, time intervals between applying a new layer. Then the paintwork will last a long time, maintaining its properties.

If you wish, you can make a stove or fireplace yourself, but in this case the question often arises of how to refine the hearth. The easiest way is to simply paint it with heat-resistant paint for fireplaces and stoves. But in order for the structure to retain its beautiful appearance for a long time, as in the photo, you need to choose the right way to paint the fireplace.

Features of heat-resistant paint for stoves and fireplaces

The stove is a structure made of bricks and stones, to which elements made of cast iron (doors, curtains, frames, covers and other elements) are added. If you wish, you can paint the entire hearth, but the choice of paint must be approached responsibly. For example, many of them indicate what materials they are suitable for. But this needs to be checked by clarifying the composition and properties of the paint. You probably won’t be able to get by with just one can, since the materials used to lay the stove have different structures, which means that the requirements for the coloring composition will be different.

Any varnish for a brick stove contains silicone or silicon. Paint for fireplaces and stoves must withstand temperatures up to 600 degrees, but some manufacturers claim that their compositions do not lose their properties even at 700 degrees. These indicators are quite suitable, since the combustion temperature of wood is 300 degrees.

Only coal is capable of heating up to a temperature of 900 degrees, but it will only be observed on the surface of the material, and much less heat is transferred to the walls of the furnace. For this reason, it is important to study the composition of the paints, because it will be necessary to use several solutions at once to paint several different parts of the structure.

If the fireplace is located outdoors, then it is necessary to use paint with high anti-corrosion properties - this will prevent the appearance of rust due to exposure to moisture. However, it must be taken into account that products for concrete and metal contain different components. You can also use universal thermal paint, which can be used to coat various materials. It forms a thin film on their surface that protects them from moisture, air and other factors that lead to rust.

What are heat-resistant paints for?

Thermal paints are able to protect materials at high temperatures. Organosilicon-based compositions are good. They are also used when painting heat exchange equipment or heating equipment, the temperature of which is higher than that of the furnace walls.

The properties of paints are significantly influenced by aluminum powder - thanks to this component, the product can withstand temperatures of 600 degrees.

Such materials serve not only for decoration, but also to increase the functionality of the stoves, promoting a smooth temperature distribution throughout the structure, thereby avoiding overheating. This is especially important for metal welds that begin to melt when exposed to heat. In addition, the paint serves as protection against released salt solutions, petroleum products, as well as high humidity, while maintaining vapor permeability.

Applying paint

Painting fireplaces requires preparation, just like any other construction work. First you need to make sure that you have purchased exactly the composition you need.

You also need to prepare the following tools:

soft cloth;
sandpaper;
water;
brush;
roller;
copper sulfate solution;
sulfuric acid solution;
spray.

First, prepare the surface that will be painted. It is cleaned of dust and dirt. Metal parts are cleaned with fine sandpaper. Be sure to remove greasy stains with a soft cloth soaked in a solution of water and salt. Soot can be easily removed with a solution of hydrochloric acid, and rust with a 10% mixture of copper sulfate.

It is recommended to apply the paint to a slightly warm surface using a brush, roller or spray - whichever is more convenient. In total, you need to make 2-3 layers, each of them should be allowed to dry thoroughly before applying the next one. The fireplace must be allowed to dry for several days; it cannot be used until the paint has completely hardened.

Applying paint to metal surfaces

First, the metal elements are cleaned with sandpaper, and the walls of the fireplace are cleaned of dust with a damp cloth. Metal dampers are treated with a 5% sulfuric acid solution and a bristle brush. It is necessary to wear gloves when working with acid. The remaining composition is washed off with a soap solution - first with a cloth, and then with a rag.

Painting the fireplace occurs after it is heated to 150 degrees. Then, within one and a half hours, apply a solution of sodium hydroxide (50 g/l) using a sprayer. Then the fireplace should stand for a couple of days. When applying paint to a warm surface, do not use a brush.

If the hearth is not built very correctly (for example, the masonry is uneven), then the surface must be plastered with lime-gypsum mortar in several layers, after preheating the oven to 150 degrees.

When painting, it is important to remember the safety rules: work with gloves and only in a well-ventilated area. It is also necessary to avoid contact of paint and other products with skin or eyes.

The metal furnace has high heat output, heats up quickly and has a long service life. But, with prolonged exposure to moisture on the surface of the metal body, for example, in a bathhouse, as well as due to constant heating to high temperatures, the walls of the furnace are subject to corrosion and other destructive effects. In this case, the appearance of the stove becomes unaesthetic. In order to protect the surface of the heater body in a bathhouse or home oven from harmful factors, as well as to give it an attractive appearance, it is necessary to cover it with paint. In this case, you cannot use ordinary enamel, since the first time the case is heated, it will change color and begin to bubble. To cover the metal surface of a fireplace or stove, you need to use a special enamel - this is heat-resistant paint for stoves.

Heat-resistant metal paint for furnaces can withstand high temperatures above 100 degrees. They have an organosilicon base with the inclusion of coloring pigments, fillers and polymers that improve its heat-resistant properties.

The composition of the enamel from a base with silicon atoms, organic radicals, aluminum powder and oxygen is resistant to the destructive effects of high temperatures, and thanks to organic resins, fire-resistant paint has such characteristics as elasticity, good adhesion, and quick drying. Do not confuse fire-retardant and heat-resistant paint: the first protects the structure from fire by swelling and forming foam on its surface, the second has good resistance to high temperatures.

Depending on the characteristics of its composition, heat-resistant paint is used to process stove bricks or only metal elements of the fireplace and potbelly stove: damper, grate, etc. Metal paint has an anti-corrosion effect. At the same time, it provides long-term protection, gives the metal case an attractive appearance, is easy to maintain, and does not crack over time due to its good adhesion to the material.

Kinds

Depending on the maximum level of temperature withstand, the following types of heat-resistant paint can be distinguished:

Enamel that can withstand a maximum of 80 degrees.
Acrylic and alkyd paint with a resistance threshold of up to 100 degrees, containing special pigments. After application, the enamel does not turn yellow, does not fade or fade. Typically used to cover iron heaters in saunas. This type of paint is produced in an aerosol form, which is very convenient for application.
Epoxy, polyurethane, acrylic enamel and epoxy primer - can withstand temperatures up to 120 degrees.
Enamel made from epoxy, acrylic, polyurethane compounds with heat resistance up to 200 degrees.
Paint with ethyl silicate or epoxy ester base with metal powder, resistant to temperatures of 400 degrees.
Silicone paint with the addition of zinc or aluminum powder. It can withstand temperatures up to 650 degrees. Available in aerosol and spray form.

In addition to resistance to various temperature levels, heat-resistant enamel for stoves is divided into types that have anti-corrosion properties and are also resistant to oils and chemicals. Regarding its intended purpose, paint is divided into types for coating cast iron, surfaces made of ferrous or non-ferrous metals. As for the packaging of enamel, it is produced in cans, aerosol cans, buckets, and barrels. The aerosol lays out more evenly, but its consumption is not economical.

Selection rules

To correctly select heat-resistant enamel, it is necessary to take into account the type of surface to be painted and its use. The paint can be used for painting bricks and or stone near the fireplace, metal elements of stoves, heating boilers, barbecues, barbecues, and pipes of heating systems. Enamel for non-ferrous and ferrous metals is a paint with a different composition, this must be taken into account. For each type of surface, the composition of the enamel may differ; this should be stated on the packaging. Enamels containing heat-resistant glass and composite materials have maximum heat resistance. For painting surfaces not exposed to high temperatures, any type of metal paint with minimal heat resistance is suitable. When choosing enamel, it is necessary to consider whether the surface is pre-primed, since not every material can be compatible with a primer.

When choosing paint for brick, it is necessary to take into account the possibility of painting with enamel not only this material, but also concrete, plastic, and wood. The cost of heat-resistant enamel can speak volumes. Firstly, it indicates the nature of the components used, and secondly, what level of temperature the paint can withstand. The cost is also affected by the container of the material and the type of mixture (aerosol or liquid). When choosing enamel, you should not focus on the manufacturer, but on the quality characteristics. The most important thing is that the heat-resistant paint is resistant to abrasion and chemical attack, protects the metal structure from rust, is harmless to the environment and humans, and is also completely resistant to temperature changes. The safest paints are water-based materials.

It is necessary to take into account that paint alone may not be enough: for metal elements one type is required, for brick another. If the stove is located both indoors and outdoors, different types of enamel should also be used. This must be taken into account when calculating the quantity and cost of the painting material. In addition, it is necessary to take into account that glossy enamel or light shades give off heat more slowly and take a long time to warm up compared to black or dark matte shades.

Application technology

Painting a metal stove in a bathhouse or a fireplace in a house begins with preparing the surface. Some compositions may require special preparation, which is usually written on the heat-resistant enamel label. If such guidance is not available, the procedure for preparing a metal surface for painting is as follows:

The stove is thoroughly cleaned of traces of old coating, chemicals, oil traces, etc. Enamel can be applied under environmental conditions ranging from +40 C to -15 C, it is necessary to take into account the level of humidity within normal limits.
The surface is cleaned of rust until a metallic shine appears using sandpaper or a drill with a brush attachment. In addition, you can use a rust converter. When even the slightest rust stains have been removed, the surface is washed and dried.
The stove coating is degreased using a solvent (solvent or xylene can be used). After this, at least six hours must pass when working outdoors and 24 hours when working indoors, then you can begin painting.
The paint is applied in several layers and in different directions; the second layer should be applied only after the first has completely dried. The surface of the metal case should not be wet or frosted, otherwise the necessary adhesion between the enamel and the iron will not be achieved. If after a short period of time the paint begins to peel off, it means that the composition was incorrectly chosen for a particular type of stove. Working with an aerosol is somewhat different from painting with a brush; the nuances should be indicated in the instructions for the paint.

Alternative to heat-resistant paint

The metal stove in the bathhouse is highly susceptible to corrosion. An alternative way to protect its surface from the destructive effects of moisture, steam and temperature changes is metal bluing, which involves chemical treatment. This method not only protects against rust, but also gives the metal structure a decorative appearance. In order to perform bluing, you must:

Clean the surface until it has a characteristic metallic sheen. The cleaner the surface, the longer the coating will last.
Remove corrosion using a mixture of 4 grams of butyl alcohol and 150 grams of phosphoric acid per liter of water.
Wash the surface with a solution of 50 grams of laundry soap per liter of water.
Light the oven until its surface heats up to 150 degrees.
Spray the metal housing with an alkaline solution.
Leave the surface to dry, after which the stove will be coated with corrosion protection.

You can make heat-resistant paint yourself. To do this, you will need liquid glass, which will need to be mixed with aluminum powder until the mixture reaches a silver color. When painting a heater in a bathhouse, such homemade paint can withstand up to five years of use.

Thus, painting a metal stove is a simple process that you can do yourself. The main thing is to ensure that the composition of the enamel matches the type of surface being painted and the temperature level. If painting is done indoors, it is mandatory to ensure that the paint is safe to prevent the release of harmful substances into the atmosphere. Universal compositions, such as anti-corrosion heat-resistant paint for metal, make it possible to paint structures when combining several functions is required.

Very often, skillful owners prefer to save on buying a stove and weld the frame for it with their own hands. However, after welding work, in order to give it a presentable appearance and extend the service life of the metal elements, it is recommended to paint the stove. Brick stoves need painting somewhat less frequently, but cracks in the masonry can also occur in them, and the brick can crumble, which negatively affects the beauty and durability of the structure. Another item that may need painting is molded oven doors. Over time they begin to rust. In all these cases, fireproof paint for the stove is used, which we will talk about in this material.

Choosing paint for the stove

The operating temperature for standard metal paint does not exceed 40-50 ℃, so you cannot paint surfaces that are too hot - it will bubble up, lose its original color and may begin to smoke and smell unpleasant. Therefore, in this case, you need to use only special heat-resistant paint for stoves.

Which of the proposed paint options to choose will depend on the area of its application. Thus, a metal sauna stove can heat up to 600-800 ℃ or more - at the epicenter of combustion the temperature is even higher. But its outer walls may not heat up so much - it all depends on the design. Therefore, you need to know how to properly install a stove in a bathhouse. If we are talking about a brick oven, then its surface does not warm up above 200 ℃.

Please note that heat-resistant paint must be suitable for interior use. And for sauna stoves you need paint with moisture protection.

A little about the types of heat-resistant paints

Painting very hot surfaces of metal furnaces can only be done with heat-resistant, heat-resistant and fire-resistant paints. But fire retardants are not suitable in this case - they are used for other purposes. When heated to 200 ℃, fire-retardant paint swells and blocks the access of oxygen to the structure, protecting it from destruction in fire. Let's take a closer look at the types of paints.

So, heat-resistant paint for stoves is used at a temperature threshold of 600 ℃. Such compositions are suitable for painting metal elements of stoves and fireplaces, as well as for metal heating appliances. But for sauna stoves they use several different types of materials - heat-resistant enamel, which is designed to heat the surface to 800-1000 ℃.

Fireproof paint for metal products can withstand exposure to open flames. Therefore, its temperature threshold is even higher. However, due to the very high cost, it is not advisable to use such compositions at home.

Another type of paint is high-temperature. Their area of application is painting heating batteries and a number of engine components. As a rule, such compositions are operated under heating conditions no higher than 200 ℃. High-temperature paint for brick stoves can only be used if it is necessary to tint the surface or paint the seams. Metal stoves cannot be painted with it.

For brick stoves, you can also use heat-resistant varnish. Its operating temperature is 250-300℃. After treating the surface with this varnish, it becomes shiny and brighter.

How to choose the right one

To choose the right paint for the stove, you need to carefully consider the label, which says what surface it can be used for, for example, heat-resistant paint for metal products. Often this information is printed in large font and is difficult to miss. In cases where the scope of application of paint and varnish products is wide, this is also written on the packaging, but in small print. Be that as it may, such information must be indicated on the packaging, as well as the name of the manufacturer. If this data is not available, there is no need to purchase such a product. It is possible that this is a counterfeit product that may pose a threat to your health.

For metal sauna stoves, use only moisture-resistant compounds, otherwise they will not last long on the surface.

Colors

In most cases, you can find heat-resistant paint for the stove in silver, gray or black. They also produce white, red, green and blue paint, but it is more difficult to find. In addition, there are matte and glossy finishes with varying degrees of gloss.

Packaging

You can purchase heat-resistant paints in various packaging - these can be spray cans or jars. From cans, paint is simply sprayed over the surface, and from a can, paint is used with brushes, rollers or special sprayers.

The volume of the cylinder is usually 500 ml. Cans are produced in 400 g, 800 g, 2.5 kg and 5 kg. There are also large buckets of 5-15 kg and barrels.

Exactly how to apply thermal paint is everyone’s personal choice. For some, it will be more convenient to use a brush or roller, while others will opt for a spray can. In the latter case, the material consumption will be significantly lower, and the paint will apply more evenly and evenly.

Which fireproof paint to choose for the stove

Paint for metal stoves must be selected with a temperature threshold of 600 ℃ or more. Here are a few of the most famous brands with a brief description of each.

Heat-resistant enamel of the CERTA brand, produced by the domestic manufacturer Spectrum. It is designed for use in the temperature range of 65-900 ℃, and its application can be carried out even in frosty temperatures of -30 ℃. The consumer is offered a total of 26 shades of paint, including turquoise, blue and yellow. True, not all colors withstand equally high temperatures. Thus, the most heat-resistant color is black (up to 900 ℃). Behind it are white, gold, brown, copper, red-brown, green, blue, cyan and turquoise (all of them can withstand up to 750 ℃). All other shades can be used at temperatures not exceeding 400-500 ℃. This paint is produced in cylinders, cans and buckets of various sizes.

Termal paint from the Finnish manufacturer Tikkurila. It is made on the basis of alkyd resins and is available in black and silver. It is able to withstand the heating of the metal at the stage when it turns red. When using this paint on sauna stoves, it does not crack or peel for about 3 years. Please note that if you heat the painted surface to 230℃, it will dry in 1 hour. This is a prerequisite for its polymerization.

Hansa brand heat-resistant metal stove paint comes in 16 colors and can be used in temperatures up to 800℃ to paint stainless steel. It goes on sale in barrels, cans and cans.

Heat-resistant paint of the Kudo brand, produced in Russia, is a silicone enamel for metal products. It is designed to heat the surface up to 600 ℃ and is available in 20 shades, including white, black, red and silver. Sold in 520 ml bottles.

Aerosol paint Bosny. Available in two versions - for heating up to 650 ℃ and up to 200 ℃. It fits well, does not change color for a long time and does not crack. This brand of thermal paint is used for painting metal, plastic, ceramics and glass, wood and fabrics. Pay attention to this brand, since glass paint is rare to find. The container capacity is 400 ml.

Hammerite brand heat-resistant metal paint has one feature. It can even be applied over rust without first cleaning the surface. However, beware of its contact with diesel fuel, gasoline and grease. The paint can withstand heating up to 600 ℃ and is available in 250 ml cans. It is applied with a brush.

Anti-corrosion heat-resistant ELCON enamel can withstand temperatures up to 800 ℃, including sudden changes. Used for painting concrete, brick and metal. Available in cans in a large number of colors. There is also an aerosol version of ELCON paint in 520 ml cans - it is designed to heat up to 700 ℃.

Paint for metal and other surfaces KO-8111 “Termika” can withstand up to 600 ℃. In addition, it has a protective effect against stray currents, salts, chlorine, solutions, oils and aggressive substances. Used for painting fireplaces and stoves. In baths, it is better to use the KO-8101 brand and KO-8104 primer from the same manufacturer. In addition to heat resistance, this paint is also moisture resistant.

Rust-Oleum heat-resistant paint is designed for very high heat - up to 1093 ℃. In addition, it protects against gasoline and oils. Release form: aerosol can. It comes in matte white, gray, black and transparent.

All of the above options are successfully used for painting brick and metal heating stoves and boilers. And some are also suitable for sauna stoves.

Preparing the surface for painting

Before painting a metal stove, it is important to properly prepare the surface. In some cases, no prior preparation is required, but in others, you must follow the instructions on the label.

Typically, preparation includes:

Cleaning the surface from traces of oils and grease, old coating, water-soluble salts and other things.
Removing rust down to gray metal using sandpaper, a grinder or drill attachment, or a sandblaster. Sometimes the surface can be coated with rust converters, but this must be indicated on the paint package. Upon completion of treatment, the surface must be washed and dried. Rust must be removed completely, down to the smallest specks.
Degreasing the surface with xylene or solvent immediately before painting. Further coloring should be carried out no later than 6 hours after treatment outdoors or 24 hours indoors.

In each case, the required number of paint layers and their direction are purely individual. If more than one layer is required, they are applied in different directions so that the paint goes on more evenly.

The temperature and drying conditions of the paint, as well as the gap between application of layers, are always indicated on the label. Following the manufacturer's recommendations will allow you to obtain a coating that will last the specified period.

Homemade fireproof paint

There are practically no reliable options for creating fireproof paint at home. The only way is to use liquid glass with aluminum powder. After mixing, a silvery composition is obtained. During the first kindling, the coating will smoke heavily, so it is better to do it outdoors. In the future, the paint holds up quite well - about 5 years, even on sauna stoves.

Choosing paint for a brick stove in a bathhouse

The outer surface of a brick sauna stove does not heat up too much, as a rule, no higher than 70-80℃. Near the cast elements, a brick sauna stove may heat up a little more, but in any case not higher than 200 ℃.

In this case, the following brands of paint are suitable:

A brick sauna stove can be painted with anti-corrosion heat-resistant ELCON enamel. It can heat up to 700℃. The same company also produces heat-resistant varnish of the KO-85 brand, which is intended for surfaces with a temperature of no more than 250 ℃. It is successfully used for decorative finishing of the surface of a brick oven.
Heat-resistant paint Certa is also suitable for painting sauna brick stoves.

KO-8101 paint is equally applicable for both metal and brick stoves.

It is worth noting that in addition to painting, there are a number of other ways to decorate a brick oven externally. To refine the brickwork, it can be plastered and whitewashed with chalk or lime. If, after plastering, the surface is puttied and covered with water-based emulsion, it will be more beautiful and will not stain clothes. The unpleasant odor of the water-based emulsion will completely disappear after drying completely and reappear. In addition, it allows you to tint the stove in any shade or apply any decorative painting in the future.

For metal elements, paint must be selected with a heating temperature of up to 800 ℃ or more, that is, the same as for a metal furnace. Before painting, parts must be cleaned of dirt, rust and old paint. Painting tape is placed on top of the brick around the steel elements and you are ready to go. Please note that when working with aerosols, the spray surface will be larger, so the area of protected areas must be increased so as not to subsequently repaint the oven itself.
