Having a structure such as a fireplace or stove in the house, it is necessary from time to time to tidy up not only their internal chimney ducts, but also the appearance of these structures.
Fireplace painted with red heat-resistant paint
But in order not to get into an unpleasant situation and not to do wasted work, you need to know which paint is most suitable for stoves and fireplaces.
Painting a metal stove
It is worth understanding that there are several reasons when you can resort to painting a brick stove.
So you can approach this issue from an aesthetic, practical and safety perspective. As for aesthetics, a stove in a house is needed not only to heat the home and make it comfortable to live in, 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 painting, it is possible to prevent the appearance of microcracks on the brick and, as a result, prevent fire in the home. There are several options for painting 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.
Heat-resistant oil paint for stoves is the best solution, since there is a large selection of colors, the paint can withstand temperatures of 600 degrees Celsius, is guaranteed to protect the brick from oxidation, and has increased resistance and durability. In addition, it is easy to apply and does not require any additional priming on the outside. However, there are disadvantages such as an unpleasant odor, toxicity and long drying time.
Drying oil is a material that cannot change the color of the brick, but only make it a little darker. As for the positive qualities, this coating is reliable and safe. The only downside is the price.
Heat-resistant varnish is a coating that can improve the technical characteristics of a brick surface.
Note! The peculiarity of its use is that it can be diluted with gouache to obtain the desired color with a tint. Cast iron is a fairly strong metal that can withstand prolonged exposure to high temperatures.
According to some sources, you don’t have to resort to painting the metal, but it’s better to do it. An excellent option for a cast iron stove is to use water-based acrylic or polyurethane paint, which has already proven itself to be excellent. In addition, the cast iron alloy can withstand even disturbances during painting more favorably

In addition, a cast iron alloy will be able to withstand even disturbances during painting more favorably.
The painting process itself looks like this. First, pre-clean the surface with a wire brush. Next, the oxidation marks are sanded using five percent sulfuric acid, and the mixture is washed off with a soap solution. Then the metal is degreased with a solvent and coated with paint. This is the whole dyeing technology. In this case, painting of a metal stove should proceed evenly. All corners with seams should be reworked as much as possible.
Note! If you do not want to drip onto the surrounding elements of the oven, you must use cellophane with masking tape
Brick ovens
You can paint a brick stove using enamel, oil paint, drying oil and heat-resistant varnish.
In the first case, the structure will be protected from moisture and 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.
Before painting begins, all loose material from the stove must be cleaned off. For this, a construction brush with metal bristles (brush brush) will be useful, or a narrow spatula will do. If the material is easily removed, then it may be more advisable to remove it down to the brickwork, in which case any paint can be chosen for fireplaces and stoves.
The next step is to remove all debris and clean the surface of dust. Next, either with your own hands or with the help of a professional, seal cracks, holes and seams. Nowadays, specialized stores offer ready-made mixtures that are suitable for working with brick kilns.
Preparing the surface for processing
Preparing the furnace surface for work
When painting a stove, the first thing you need to do is prepare its surface for painting. A stove with new masonry does not require any special operations, only cleaning from dust. If the stove is plastered, pay attention to the thickness of the plaster layer.
To clean the surface of the oven you will need the following equipment:
- Metal spatula to prepare the surface and also for puttying;
- Brush for removing remnants of previous finishing.
If the layer of plaster is more than one centimeter, the plaster requires dismantling - crumbling areas are removed, the surface is cleaned using a metal spatula, brush or sandpaper. All cracks and missing parts are covered with lime-clay or gypsum mortar.
After the solution has dried, wipe the surface with a damp cloth, wait for the water to dry and you can apply the coloring agent.
To ensure good interaction of paint with other substances, you can saturate the surface of the stove with a primer before painting it.
How to choose paint, taking into account the cost
Many people, going to the market, do not even try to understand where the pricing policy comes from. They purchase the first product they come across, at a significant price, and after a while they only get frustrated. You always want to spend your money rationally so that your purchase always meets your expectations.
To avoid such situations, you do not need to listen to positive reviews from sellers; they are interested in selling expensive goods. Therefore, it’s a good idea to look at the label. Often, domestic paint is passed off as a European product, and the price is almost the same, but the production characteristics leave much to be desired.
Foreign manufacturers are always concerned about environmental friendliness, durability and wear resistance, which cannot be said about Russian companies. Therefore, it is often not a matter of the brand, but of real facts. It’s better to overpay once, but buy a really high-quality product. Your own health, safety and nerves will cost much more. The choice of paint is often made based on the price tag in the store, but you also need to read the recommendations on the packaging.
Particular attention should be paid to consumption. Compare not banks, but square meters
High-quality paint will take less than cheap paint in two layers. Therefore, in the end the price will be the same, but the appearance will be different.
Consider in advance the area of work, in which room the repair will take place, and what basic characteristics will be acceptable for it
So, for the nursery it is important to choose environmentally friendly, non-toxic, and for the kitchen wear-resistant
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.
Assortment of paints
If you are looking for an answer to the question of how to coat a new brick oven, then it is best to use special varnishes or paints. The main feature of such materials is that they can easily withstand high temperatures without cracking or peeling from the base.
In the store, be sure to look at the label, it should contain the “heat resistant” parameter, then the material will definitely be suitable for the job. For many years, materials from the KO company with the markings 168,174, 813,835A, 868, 1112 have been especially popular.
Heat-resistant paints for stoves and fireplaces, if they have a thick consistency, must be diluted. For this purpose, you can use ordinary solvent 646, white spirit or turpentine.
It is very important that the painted brick does not have smudges, and the application is carried out in two layers
It is worth noting that heat-resistant paint can be of various colors, when mixed, the most extraordinary shades are obtained, while some types of material can withstand temperatures of up to 600°C degrees.
Compositions for working with stoves and fireplaces
If owners are looking for an answer to the question of how to paint a cast iron stove, then in this case they can use Certa material, which prevents the corrosion process. It can also be used for brick surfaces, or for processing metal elements in stone ovens: grates, grates, doors, valves, etc.
The presented fireplace paint is also produced in the form of aerosol cans, which simplifies the application process. The color scheme consists of 16 shades, so you can easily choose the right option for yourself.
Many people don’t know how to paint a red brick stove, because in most cases it has a beautiful shade. To protect structures from the adhesion of dust and soot, as well as to embellish the appearance, heat-resistant colorless varnish from Elcon is suitable. Its peculiarity is that it is able to withstand temperatures from 500 to 2500°C degrees.
There is another well-known paint for brick stoves - KO (815 or 85), which also has high resistance to temperature changes. Before purchasing, it is imperative to read the instructions on the packaging, because the compositions of some coloring substances require exclusively hot application.
You can use an environmentally friendly coating for brick stoves and fireplaces. The material is available in the form of varnish and is produced by Olympus. The main feature is the ability to withstand temperatures up to 1500°C, which is why some technical structures in enterprises are covered with it.
If your home has a stove painted with a special material, then we can say with confidence that it has a high-quality heat-resistant base. It is thanks to her that the design will delight the owners with its beautiful appearance for many years.
In villages, Russian stoves have long been treated with ordinary whitewash, giving it a neat appearance.
It is believed that the most popular stove design styles are Provence and country.
Nowadays, the choice of building materials is so wide that it is sometimes difficult to give preference to anything. Many people do not know what to do if they inherited an old stove along with an old village house or bought such a stove along with the household. With such a huge number of finishing options, many are interested in the question of how to update a sauna stove or paint a fireplace correctly. And if the stove is made of brick, how to paint it?
If the stove is built correctly, it can transfer at least half of its heat to the room. In addition, the amount of heat radiated into the room directly depends on the material with which the surface is covered. With a smooth surface of the structure, less heat is given off compared to a rough surface. If you paint a brick sauna stove with oil or enamel paint, it will radiate heat much better. The darker the color, the more intense the heat transfer will be.
When can I heat it after painting?
After painting, the structure cannot be used until the paint or varnish is completely dry. How long this will take depends on the paint and varnish used and the number of layers applied.
The deadlines for different materials are as follows:
- The drying time of heat-resistant paint depends on the components included in it, often taking only an hour;
- The first layer of heat-resistant varnish dries in an hour, a total of 2-3 applications are needed, subsequent ones take longer to dry;
- It usually takes up to 2 hours for silicone enamels to dry;
- natural drying oil dries within 24 hours if the temperature is kept above 20°C.
Regardless of the paint and varnish used, it should dry completely within a day. It's better to wait longer for everything to dry completely. Impatience can result in complete failure, and then all the work will have to be done again.
Even an inexperienced user can handle painting a heating structure if you follow the work algorithm. Coloring can be done using different materials; one of the main conditions is the heat resistance of the selected product. You can make it yourself, which will reduce costs.
Painting the fireplace
A fireplace is an extremely fashionable accessory for a living room, both classic and modern. In a country house you can find both this option and a more traditional one - a stove, both Russian and Dutch.
And if the hearth plays only a decorative role, then there are no problems with its finishing - any material will do. But when it comes to an existing structure, questions arise. We will tell you in this article how it works and how much it costs to lay clinker tiles.
- The main thing in this matter is the coefficient of thermal expansion. Obviously, if the cladding has this indicator less than the brick, the heat simply will not be transferred. Clinker tiles have a coefficient of 7–8%, which is considered sufficient.
- Thermal conductivity is the ability of a material to conduct heat. It would seem that metal has the best performance here, but fireplaces are never finished with it, since metal heats up excessively and poses a danger to others. And the function of the stove is not only to quickly heat the room, but also to maintain the thermal regime. The thermal conductivity of clinker is, in principle, rather low, but here another property of the material comes to the rescue.
- Heat capacity is the ability to accumulate heat and release it gradually. This property of all ceramic products is highly valued by stove makers, so clinker ultimately turns out to be a completely suitable material, but only for a fireplace.
For cladding, it is preferable to choose clinker produced by the semi-dry method.
- Extruded tiles are denser, and the higher the density, the lower the heat capacity and ability to conduct heat.
- The semi-dry method allows you to obtain a material that is more porous, and, therefore, with better expansion coefficients. Of course, such tiles are not suitable for facade decoration, but for fireplaces they are the right choice. But even in this case, you should find another material for heating stoves - terracotta tiles, for example, or tiles.
The remaining properties of clinker are not so important, although they are useful.
- Fire resistance - the finishing of the hearth must be durable, and therefore resistant to high temperatures and constant heating. Clinker fully meets these requirements.
- Durability, or rather, resistance to scratches and mechanical damage, has a very positive effect on preserving the appearance of the fireplace.
- Water resistance is of indirect importance, since fires are usually placed in dry residential areas. But for those cases when the stove is in the kitchen or separates the work and kitchen areas, moisture resistance is in demand.
- Of course, chemical inertness, the ability not to accumulate dirt, and so on are also important. Clinker is easy to clean; household chemicals are completely acceptable when cleaning.
- Wear resistance in this case does not matter.
Clinker tiles for the stove (photo)
Not every tile is suitable for finishing, and it’s not always a matter of quality.
- Heat resistance – indicated by the letter “T”. The tile must be fire resistant.
- The preferred thickness for a fireplace is 6–8 mm. It is impossible to go thinner, since here the material experiences constant heating, and thin tiles will quickly collapse. Square tiles measuring 120*120 mm are considered the best for cladding. With large dimensions and maintaining the same thickness, the rigidity and strength of the masonry decreases. And with increasing thickness, problems with fastening arise: the glue has a limited ability to hold weight.
- The color of the tile should vary within small limits, unless, of course, a special decorative technique is used.
- For tiles, dimensional accuracy is very important. It’s not even a matter of the aesthetic side of the issue: with different dimensions, it will not be possible to lay the tiles tightly. Therefore, the clinker should be checked: put 2 tiles together “facing” each other, and then the wrong side. There should be no gaps between the surfaces. Defects on the front side do not allow the formation of a flat surface, and on the back side - the laying of tiles. According to this parameter, clinker is divided into 2 classes - “A” and “B”. The first promises more accurate dimensions.
- Cracks and chips clearly indicate low quality of the product. Moreover, cracks on the reverse side are no less dangerous - this is a guarantee that the tile will burst under the influence of temperature in the near future.
- For cladding you need to choose unglazed clinker. The enamel layer significantly affects the coefficient of thermal expansion, and is not resistant to temperature changes.
How to paint a brick fireplace
Possibility to paint a brick fireplace. Why not. A great way to update your fireplace and room with a fresh look without ruining anything with expensive renovations. Plus, repainting brick gives you the opportunity to show off your talent in decorating your fireplace.
Materials
Masking tape or paper
Primer or conditioner
Paint tray
Painting method
Choose the color you want to paint the fireplace. If you are unsure about choosing the number of different paint colors, look around. Let, for example, be the colors of curtain fabric, chair upholstery, pillows, etc., etc.
Prepare peeled brick. To clean, use sandpaper to remove any bits of mortar on the surface of the brick, then use a vacuum cleaner to remove dust and dirt. Then we fill a bucket with water and soap, wash the bricks with a hard brush and let them dry completely. We pass again, picking up a vacuum cleaner.
Place paper or duct tape around the fireplace in areas where you don't want paint. The most important stage of preparation will allow you to save a lot of time from unwanted mistakes.
If you want to show off your fireplace in the center of the room, paint the walls a different color. You can have both the fireplace and the walls in the same color, the choice is yours.
Find a brush that will go along the cracks between the seams of the bricks. We take a primer and cover the fireplace bricks. Then let the primer dry completely. Choose a paint color and start painting. Use high quality latex paint. Let's start painting the bricks using our rollers and brushes. We painted it in one layer, wait, let it dry, and paint again. Once the paint has dried, we paint it a third time.
How to make a beautiful interior with a fireplace in your home
Have you already got your own apartment or country house with a wood-burning fireplace? Then it's time to start decorating the interior of your living space. However, a newly built building is not always equipped with decorative items of decent taste and skill. Some owners begin to clutter the room with too much furniture, unnecessary accessories and the like. In another case, there are too few decorations in the room, only the most necessary items for life, which indicates a low aesthetic level of the owner of the house.
The quality of a successfully designed interior of a residential building directly depends on the finishing and equipment. To do this, it is necessary to use only the best materials in a timely manner and perform all work at the proper level.
The main work when decorating a home with a fireplace is wallpapering or adhesive painting. Thus, if you are painting with adhesive, you must remember that to avoid contamination in the lower part of the room you need to use special panels, but this creates a feeling that the height of the rooms is insufficient. That is why experts recommend painting walls to their full height and using paint of the same tone.
You can paint the walls one tone, but the frieze parts - a different color. A baguette is made at the border of different colors; a joint is also possible, which is made in a straight line.
You should not use a variegated wallpaper pattern, as this creates an unfavorable impression when perceiving all interior items. The best option would be plain wallpaper with a calm color scheme.
The windows of a brick house are usually painted white. Today, plastic bags are often used, which do not require frequent painting, do not freeze in winter and do not sweat during the off-season.
Panel glazed doors are most often used as doors. Of course, providing doors with corrugated glass belongs to a bygone era, but such doors are a good option for interior design in a retro style. Glass of this type creates a soft lighting effect and eliminates visibility. You also need to be careful when choosing a variety of door elements, such as bolts, handles and screws.
The best way to decorate doors is to paste them with a special film. You can use film that copies valuable tree species. Some owners of country houses use decorative plywood or fiberboard cladding; you can use veneer, which is subsequently painted with varnish. If you paint interior doors with oil paint, you must remember that they should be somewhat lighter than the walls of the house with a fireplace.
How to Improve the Look of a Decorative Fireplace
A similar procedure is used with the use of substances of the same color scheme as the walls. In some cases, the fireplace can be equipped with elements such as wooden or plastic decorative grilles, which have a better effect on the external perception of the interior of the house. It is better to paint the ceilings in light white or beige tones. The fact is that the use of such shades affects the reflection of light entering the rooms and increases the effect of natural lighting, and therefore increases the living space of the room. There is a secret that lies in the difference in the colors used to paint the walls and ceiling. So, if you paint the walls of the house in calm, warm colors, the ceiling should be given a cold tint, and when decorating the walls in cold colors, the ceiling should be painted in a warm yellow or slightly pinkish color.
An important component of the house is the floor. Often the floor is traditionally equipped with parquet, which should have a beautiful pattern and quality. Plank floors can also be used as a covering, but they should not have wide seams. Such floors are usually painted in lighter colors, which must be combined with the color of the walls. You can cover the floor with fiberboard slabs, the seams of which are sealed with nitro putty or epoxy-based putty. After this, the floor is covered with two layers of oil paint and one layer of varnish.
Tile style
As for the appearance of the fireplace, here you can come up with anything you want, and at the same time turn all these ideas into reality. This article about what methods exist for creating the appearance of a fireplace will help you choose the most suitable style for facing the fireplace.
One of the most cost-effective ways to decorate a fireplace is by covering it with plaster. It is applied quite densely, more than five layers. First, you need to spray the fireplace with a special liquid solution. Each subsequent layer must be applied with plaster, the consistency of which should be similar to dough. In the interval between procedures, the building material should have time to dry. The very last step is painting the fireplace itself.
Water-based paint - the right choice
When choosing an element such as heat-resistant paint for stoves in the country, it is necessary that it be stable, reliable and durable.
Note! It is better that it dries quickly and is moisture resistant and does not have a burnt smell
Heat-resistant paints
Heat-resistant paints for stoves are dispersion paints made from an acrylate substance. They are made on water and hydrocarbon bases. To paint boiler bricks and plaster the surface, any acrylic mixtures are suitable. Specialized heat-resistant metal paint for furnaces would be perfect.
We invite you to familiarize yourself with the House with a bathhouse under one roof: projects, photos and video materials
In everyday life, water-dispersion types of thermal paints are more often used, which are designed for the use of a cast-iron stove with plaster heated to four hundred degrees Celsius. There are heat-resistant paints with organosilicon compounds, acrylic and alkyd components.
Water-based paint is a group of paint materials, the most popular of which are a composition of acrylic, polyvinyl acetate, latex, silicone and silicate. The advantages of each of the above compositions are heat resistance, moisture resistance, strength, minimal cost, ease of use, short drying time, environmental friendliness, and wide variation.
Note! As for the disadvantages, they are the presence of an unpleasant odor during the drying process, but there is no odor during the operation of the stove equipment; the paint for the stove penetrates deeply enough and the coating peels off or changes color when exposed to strong heat. Often, many home owners, when choosing paint for the stove, pay great attention to taste preferences, forgetting about its quality characteristics
The paint must be heat-resistant, only in this case it will satisfy all the needs and wishes of consumers. Organosilicon enamel, for example, has such properties.
Often, many home owners, when choosing paint for the stove, pay great attention to taste preferences, forgetting about its quality characteristics. The paint must be heat-resistant, only in this case it will satisfy all the needs and wishes of consumers
Organosilicon enamel, for example, has such properties.
Advantages of heat-resistant paint:
- it has excellent wear resistance and heat resistance;
- such a coating has electrical insulating properties;
- with its help, brickwork is protected from oxidation, which increases its strength and endurance;
- The painting process is simple and does not require preliminary priming;
- The shelf life of its operational characteristics is long - about 10 years.
Disadvantages of heat-resistant paint:
- the composition has quite aggressive properties, which can be dangerous to the health of humans and domestic animals;
- the paint has an unpleasant odor, which makes it impossible to use it in a house where people with respiratory problems live;
- the compositions have a long drying period, which may be associated with certain inconveniences;
- The presence of toxic substances in their composition makes it mandatory to use respiratory protection and skin surface protection during work.
Heat-resistant paint is toxic and very harmful to health.
Advantages of using it to paint a stove:
- The paint dries very quickly, but subject to constant high temperature.
- The composition is absolutely safe for the health of people and animals.
- Unlike other products, this paint does not have an unpleasant odor.
- The ability to create your own, individual palette using various pigments, while this is impossible with other paints.
- The painting process does not require much effort and time. You can use a brush, sponges, a special roller, or other convenient accessories, which greatly simplifies the work.
Rules for selection and use
To choose the right paint, you need to determine the maximum temperature of the surface on which it will be applied. You also need to calculate the area and make a choice between a spray in a can and a liquid consistency in a jar. But there are still some rules that you need to know.
Specific nuances in terminology
Many salespeople in their advertising campaigns are very frivolous with the terminology adopted for compositions that can be applied to surfaces with high temperatures. There is no normatively established gradation according to the correspondence between the name of the composition and its maximum permissible heating temperature.
However, three established terms are usually used:
- high temperature;
- heat resistant;
- heat resistant.
High-temperature paints for metal include compositions that can withstand prolonged surface heating up to 2000C. They are used for processing radiators and heating pipes, brick stoves and fireplaces. In addition, they are suitable for automotive parts such as engine, muffler and exhaust system.
Water jacket of a metal furnace. From the outside, it does not heat up above the temperature of the coolant, so high-temperature paint can be used to treat its surface
Heat-resistant compounds are used for surfaces with temperatures up to 6500C.
These paints are used for the following metal objects:
- sides and bottoms of furnaces;
- barbecues;
- pipes for exhausting combustion products;
- the junction of the water circuit pipes to the furnace or boiler.
Heat-resistant paints and enamels often contain pigments that give them color, so they can be used to create original interior design solutions.
Heat-resistant paint is designed to cover surfaces that are heated to temperatures above 6500C. First of all, these are cooking stoves and furnace fireboxes, as well as grates for wood-burning stoves and fireplaces.
Some types of thermal paint have an additional feature - fire resistance. This means that the painted surface may be in direct contact with the flame. Among household metal objects, this is relevant for the fireplace grate and the inside of the barbecue.

Heat-resistant paint is essentially heat-resistant enamel. To create an impermeable barrier, it is necessary to perform a thermal hardening procedure. In the process of heating the surface with the composition applied to it, polymerization of the layers occurs, after which the access of air to the painted metal is stopped.
Sometimes, to protect metal products, a colorless varnish is applied to them. This type of coating also requires thermal hardening
It is after thermal hardening that neither oxygen, which causes the rusting process, nor moisture can penetrate under the enamel. Before this, the paint has only a decorative and, partially, protective function from physical impact.
Moreover, after creating an impermeable layer, the evaporation of substances contained in the paint into the room air stops. Therefore, ideally, it is necessary to wait until the specified period of complete drying, which is indicated on the label or in the instructions, and then immediately carry out the thermal hardening procedure.
Typically, the temperature at which enamel polymerizes is 200-2500C. This leads to one common mistake that is often made by people who have leftovers after painting their stove.
You cannot apply a heat-resistant compound that requires heat hardening to radiators and heating pipes, since the degree of their heating is insufficient to complete the process. For slightly hot objects, you need to use ordinary high-temperature paint.
Theoretically, the thermal hardening process should take place at a constant temperature for 30-60 minutes. However, in practice, such “laboratory” conditions are impossible to achieve.
Therefore, wood stoves, barbecues and fireplaces are not heated to full capacity and their heating is gradually increased. Typically a test run takes 1.5-2 hours. Another option is heating with an industrial hair dryer.
What paint to paint a brick wall: two main options
There are two types of coloring compositions that are used in one way or another for decorating surfaces - these are paints based on organic solvents and so-called water-soluble paints. Both have their advantages and disadvantages, which we will get acquainted with further.
- Paints based on organic solvents. These are oil and nitro enamels, which create a thin waterproof film on the surface of the material - they penetrate the structure of the brick quite well, but deprive it of the ability to absorb moisture vapor, which is not good. In addition, in most cases these are glossy paints. They are great for outdoor work, but when it comes to interior decoration, you need to be careful with them. By creating a waterproof film on the surface of the brick, they create the preconditions for the formation of condensation. They can be used on partitions, but not on external walls. In all other respects, these are pretty good coloring compositions that can decorate surfaces in any color.
- Water-based exterior brick paint. These are the most common paints for bricks and have many advantages, the most important of which is vapor permeability. They can be used with equal success both indoors and outdoors. In addition, almost without exception, water-based paints can be tinted independently, giving them any shade. They are absolutely fireproof and have no pungent odor. To decide what paint to paint a brick wall with, acrylic paint is most often used - it has become widespread due to its low cost. If we talk about the really best paint for decorating bricks, then here we can name acrylic-silicone paint compositions without any options. They are the ones who possess the set of qualities that are so necessary for the long service life of the brick and giving it a unique look. Unlike all other compounds, they have high strength and the ability to withstand natural factors.
But, as they say, the paints for brick described above are not the same - by and large, you can use any, just remember that it must meet certain requirements set out above. Otherwise, there can be no talk of a long service life. Also, the service life of the painted surface is directly influenced by the paint application technology itself, which will be discussed further.
Types of professional materials
The range of paints and varnishes for stoves is presented by Russian and foreign manufacturers. You can find paint for any budget with any characteristics. The product can repaint the stove a different color or give it a darker or lighter shade.
Organosilicon compounds
This type of composition includes various mixtures created on the basis of organic resins. These can be paints, varnishes, enamels. Used for exterior finishing work and painting interior elements in the house. The choice of dye and its characteristics is determined by its purpose.
To cover the surface of stoves and fireplaces, heat-resistant silicone paints are used. When purchasing, it is important not to confuse the composition, since moderately heat-resistant solutions are produced with a similar name. They cannot withstand temperatures above +100°C.
The positive features of such mixtures include:
- Good adhesion. The paint is easy to apply to any texture.
- High strength.
- The formed shell protects the oven well from moisture.
- Long service life.
- Good heat resistance and elasticity. The paint can withstand about 250 cooling and heating cycles without losing its properties.
The coloring matter has one significant drawback - the limited color palette. This is due to the chemical composition and scope of application.
To apply enamels and paints, use a roller, brush or spray gun.
Heat-resistant acrylic paints
The group of heat-resistant acrylic paints includes water-based or hydrocarbon-based materials made from acrylates. They are able to withstand temperatures up to 400°C depending on the composition. In domestic conditions, water-dispersion paints are most often used, although water-based substances can be used.
Alkyd emulsions
The name of the substance “alkyd” consists of two definitions: alcohol and acid.
Emulsion paint contains alkyd varnish, a coloring agent and a solvent, which is most often white spirit. Also, different types of paints may contain marble and granite dust, as well as additives against fungi, mold, and fire. Alkyd emulsion is used to coat the body of a stove or fireplace. The temperature on the surface should not exceed 100°C - this is the main disadvantage of such products. At the same time, the color palette is very diverse. It is also important to note the low elasticity of the solution. It does not withstand temperature expansion, which is why after a year small cracks form on the painted surface of the stove.
Heat resistance is increased by adding aluminum powder to the water-based solution. But such compositions are not suitable for painting stoves and fireplaces.
Dyeing process
When laying new paths and sidewalks, professionals recommend buying colored tiles, the range of which is so large that you can choose for any landscape design.
Colored products from the manufacturer save effort on painting
If there is no suitable shape or color from the proposed material, it is made to order.
To make tiles with your own hands, it is recommended to add acrylic paint of various shades to the solution.
When the tiles have already been laid, their color is changed in a different way: first they learn what they use to paint and how to paint paving slabs, then they choose the required shade and paint the surface.
Choice of paint: varieties
Depending on the work performed, paints are divided into the following types:
- façade – intended for external walls;
- interior – for interior work.
Let's take a closer look at the interior ones, which in turn are divided into moisture-resistant, non-moisture-resistant, vapor-permeable, and wear-resistant. You need to choose the appropriate base based on the room in which the colorful work is planned.
There are two more important parameters - tensile strength and thixotropy, but they are usually paid attention to by real professionals who have been working with paint and varnish products for a long time.
Decor
We must not forget about additional decor and harmonious coverage. A stove arch often turns black from smoke, regardless of the quality of the brick coating. To cover this part of the stove, you can use metal elements or decorative stone overlays.
The color scheme is also important, which should be in harmony with the room and furniture. It is better to choose a color based on the shades of the floor, ceiling or walls. Remember, if clear enamel is used for painting, it will still have the tint of the wall.
If you decide to install additional decorative elements, then it is important to choose the right adhesive composition for them. Not all substances can hold elements on a painted wall for a long time.
You can create an unusual design using different paint colors. For example, paint all the bricks in different colors.

What is used today
Modern paint and varnish compositions that are exposed to thermal effects can withstand heating up to +350…+400 ºС. The flame temperature in the firebox where the wood burns reaches +450 ºС. When the fuel is coal, it increases to +1000 ºС.
The outer surface of the stove does not heat up as much as the firebox. However, to cover it you should choose heat-resistant paint or varnish that can withstand heating up to +400...+550 ºС. Heat-resistant paints and varnishes are manufactured for different purposes and different surfaces. Manufacturers indicate on the packaging the temperature resistance of the coating, as well as the type of surface for which it is intended: brick or metal.
The range of fire-resistant compounds includes coatings of various shades. Colorless varnishes preserve the natural appearance of stone or brick for a long time.
Natural drying oil
Coating with natural drying oil does not change the natural shade of the brick, but makes it darker. The peculiarity of drying oil is that a heating device coated with this composition can only be heated for a limited time. Therefore, it is not suitable for stoves located in residential premises and is used to cover heaters installed in the bathhouse.
Organosilicon paint
The basis for the production of silicone coatings for stoves or fireplaces are organic resins. These paints and varnishes have good adhesion to surfaces of various textures. They form a durable, moisture-resistant coating that can withstand up to 250 heating-cooling cycles. The disadvantage of organosilicon compositions is the lack of color solutions, which is due to the chemical properties of these coatings.

Alkyd based varnish
Alkyd paints and varnishes can be used for brick surfaces that do not heat above +100 ºС. Manufacturers of the compositions introduce into them marble or granite dust, components with antifungal and fire-fighting properties. The disadvantage of alkyd compositions is their low elasticity. Varnishes are not able to withstand the constant thermal expansion of ceramics, so the coating requires annual renewal due to the appearance of small cracks on its surface.
Heat resistant paint
Painting of brick or plaster-covered stoves, chimneys and fireplaces is carried out with heat-resistant paint that can withstand heating up to +200…+400 ºС. Varnishes that can withstand high temperatures should also be included in this category. Their operating temperature is +250…+450 ºС.
Heat-resistant compounds not only withstand prolonged exposure to high temperatures, but they are safe for humans because they do not emit hazardous substances when heated. Heat-resistant coatings do not affect the heat exchange between the heating device and the room air, are resistant to detergents, and are elastic. To provide the stove surface with a uniform, uniform coating, you need to apply 2-3 layers of paint.

Functions of the paint and varnish coating of a brick heater
Painting a stone heating device is carried out for the following purposes:
- protection of the stove surface from absorbed contaminants, and clothing from brick dust upon contact with brickwork;
- facilitating daily care, that is, maintaining the necessary sanitary and aesthetic condition;
- increasing the decorative design class of the unit;
- adapting the design of the heating device to the existing interior.

If the bricklaying was done without sorting the stone by color, then painting the body with a heat-resistant paintwork material (paint and varnish material) of one or more colors will correct the situation. But even a stove finished with face brick is transformed after applying, for example, a colorless paint coating, which gives a richness and matte hue to the stonework.
How to choose paint?
Before buying paint, you need to consider some nuances so that it best suits the surface you are treating.
If you are going to pre-treat the surface with a primer, then you need to select a paint that is compatible with this material.

In addition, make sure that instead of heat-resistant paint you are not sold fire-resistant paint - such confusion arises quite often.
This paint is truly resistant to open flames, but its effectiveness is limited - it will quickly begin to deform and come off.
The purpose of heat-resistant paints is not to protect an object from fire, but to resist the effects of corrosion on it in high temperature conditions. This is what you need to be guided by when choosing paint for stoves and barbecues.
Such paints are more expensive, but otherwise using the mixture will be useless, so it is better not to waste money and buy a suitable mixture once.
You also need to consider what temperature the coating will be constantly exposed to: if you buy a mixture whose stability is less than necessary, it will very quickly become unusable, and the coating will have to be replaced again.
When choosing paint for barbecues, stoves and other products, you need to consider what type of metal you are buying it for: colored, black or other varieties.
Most types of paint take this point into account, and you can find out for which surfaces it is suitable by looking at the description on the package.
Price is not the last factor when choosing a mixture for coloring, especially considering that they can differ significantly from different manufacturers.
The price depends on several points: what components were used in the preparation of the mixture, what temperatures it was designed for (the higher, the more expensive), what type of mixture it is (there are liquid and aerosol), in what container it is sold.
For a barbecue, paint that can withstand exposure up to +100 degrees is suitable - this is the most popular type of mixture, and it costs about 170 rubles / kg.

If you want to buy a coating with an aerosol spray, then one 0.3 mm can will cost you about 1000 rubles - this is significantly higher than the price of standard liquid paint, although using aerosol paint is, of course, more convenient.
You should buy a coating based on the required characteristics, but you don’t need to pay too much attention to the manufacturer, because many mixtures, for example, foreign ones, are more expensive precisely because of the brand, and not due to their high technical characteristics
The most important thing is that the mixture meets the basic requirements: it is resistant to chemical attack and abrasion, protects the metal from corrosion, does not emit any harmful substances, does not enter into chemical reactions with other means and is completely safe for humans, and is also resistant to temperature changes .
If the mixture you purchased meets all of the above properties, then it will not need to be replaced for a very long time.
Application feature
There are no requirements for applying heat-resistant enamel as such. Painting is done with a roller, sprayer or brush. If you purchased enamel in a can, then you do not need tools.
Before applying paint, it is necessary to first prepare the surface, that is, remove rust, degrease and remove dirt. Before work, we recommend that you mix the paint well, after which the mixture should be kept for several minutes to remove air bubbles. We recommend applying the enamel in several layers. Apply the next layer after the previous one has already dried.
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 this 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. Date: September 25, 2021
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.
