A stove in a private home is a popular element of the interior; it allows you to create additional warmth in the room and decorate the decor of the rooms. The most acceptable option to improve it after installation is painting.
To find out how to paint a brick stove in a house, you should understand why it is so necessary to cover the stove with paint and varnish, and study the correct algorithm for painting work. The article covers these issues, and also provides the types of paints and varnishes suitable for application to a brick surface that will be heated to high temperatures, the tools necessary for the work, and step-by-step instructions for painting.

Why painting is needed
A stove in the house is an interesting design solution that allows you to significantly save on space heating. Previously, brick structures were not treated with anything; at most, they were plastered or covered with lime. The stoves did not have a presentable appearance, and the lime coating very quickly lost its appearance. Today, construction stores sell a lot of facing material that can be used to cover brick stove walls, but this option is expensive, unlike painting.
Therefore, the brick structure needs to be painted, but the composition of not every substance is suitable for this process.
During heating, brick elements joined together with cement mortar begin to lose their tightness over time. Clay plaster prevents this process, but it is not presentable, and paint can improve the appearance of the stove and also provide additional protection to the plaster composition. There are many paint options that are not sensitive to high temperatures and changes.
Regular paintwork quickly cracks and smokes heavily in the chimney area. The first problem will be solved by a high-quality composition adapted to the increase in temperature, and the second by finishing the furnace arch with additional elements.

It is important not only to choose the right paint, but also to prepare the surface and properly care for it in the future. The work is carried out in several stages.
Is it possible to paint a metal stove?
Painting a metal stove is an essential process, but there are a number of additional factors to keep in mind. For this task, only heat-resistant paint for metal stoves is suitable, which can easily withstand exposure to prolonged temperatures. Many furnace owners choose a cheaper option that is not suitable for such tasks.
It is unacceptable to paint a metal stove with ordinary paint, since a number of useful functions of the paint and varnish material are lost, including:
- Heat resistance, which allows the metal to serve for many years without degradation under the influence of high temperatures;
- The absence of materials and additives that evaporate when heated and have a toxic effect on the body of others;
- The presence of protective properties against corrosive changes;
- Moisture resistance.
As you can see, the number of useful properties that paint for an iron stove should have is really many. Try to carefully understand the issue so that the service life of the product is maximum.
Types of paints
Leaving the stove structure in its natural, unprocessed form is not the best solution. If you do not want to hide the brick surface, then it is enough to cover it with colorless paint. This event will not hide the relief of the walls, but will protect the coating from negative factors and make the overall appearance attractive. To understand how to paint a brick stove in a house, you need to learn more about the options for dyes and their compositions.
Types of paintwork:
- Water-based acrylic substances . They have a budget price and are easy to apply with a regular brush or roller. The only drawback of this paint is that it is afraid of humidity, so it is not advisable to use it where this indicator is high.
- Polyurethane . They are famous for their heat resistance. Their heating limit is up to 600 degrees, but a side effect is possible. Some polyurethane paints may discolour slightly.

- Organosilicon enamels . Unlike previous types, they are more expensive in price, but have many advantages. They can withstand temperatures up to 800 degrees, are made from environmentally friendly materials, have an increased durability, and do not contain toxic substances. During operation, economical consumption is observed.
- Substances based on lime and chalk . Not suitable for red brick, they are inexpensive, penetrate well into stone, have an antifungal effect and are easy to apply.
Disadvantages of lime products:
- Requires multiple applications.
- Touch-up is required (at least once every two years).
- There is a risk of incorrectly calculating the consistency.
- The brick wall must first be treated with water-based paint or plastered, which means additional costs and time.
If the owner of the house decides to start processing and does not know how to paint the brick stove in the house, it is better to give preference to silicone enamel. It will not cause harm to residents, will ensure the safety of the brick, and will create a presentable appearance of the stove structure.

Criterias of choice
There are a lot of paint and varnish products in construction stores. If you are not knowledgeable about paints, pay special attention to the information on the packaging. Basic information:
- compound;
- appointment;
- humidity indicators;
- manufacturer;
- price.
There are various varnishes, paints, enamels that have a high-quality composition, but are not suitable for a home brick oven, but are intended exclusively for industrial premises or the street. The packaging should be marked “heat resistant”.
When purchasing paint, you should make sure that it has a certificate. Dubious products are created from untested ingredients, which can lead to loss of health, not to mention the attractiveness of the paintwork. High-quality paint cannot cost less than 135 rubles per kg.
When considering options for painting a brick stove in your home, it is important to pay attention to the temperature indicator declared by the manufacturer and the protective functions. You should choose those brands that are offered by companies that have their own factories for the production of paints and varnishes and quality control.

Which steel is better to choose?
For different options for using and installing the furnace during production, you will need to use different types of steel, including heat-resistant steel. We will analyze the main places for possible installation of the furnace and the optimal choice of steel for its production.
For sauna stove
In this option, the heater will heat up to a maximum of 5000, so deformation of the structure is possible if the production technology and choice of material are not followed. But individual parts heat up differently, so the grade of steel for a sauna stove may vary for its different parts:
for the production of the combustion chamber, you will need to prepare blanks from steel, grade AISI 430 or 08Х17Т. But such steel is difficult to obtain and expensive to use when making a stove yourself. In this case, you can use structural steel, but of a higher grade
The best option is St-10; to prevent direct passage of heat into the chimney, you can use simple structural steel or 08PS, 08Yu on the heat screen; for the production of the body, you can prepare the usual St-3; For the firebox door, it is important to prepare good material from heat-resistant steel or cast iron. In specialized stores or at flea markets, you can find excellent used doors for little money;
Important! When selecting material for self-production or buying a ready-made heater, pay attention to the thickness of the workpieces. If a heat-resistant alloy is used, the wall thickness is 4 mm. When using ordinary structural steel, the parts must be made of metal with a thickness of 6-8 mm.
When using ordinary structural steel, the parts must be made of metal with a thickness of 6-8 mm.
For home
The structure is exposed to long-term thermal loads, so it is important that the parts are made of good material. You can use steel for a sauna stove for a home potbelly stove, but it is better to prepare blanks from alloys with a chromium content of 12% or more
The famous stoves of Professor Butakov from and are made from such a sheet. They will last much longer than homemade ones made from scrap materials. We should not forget the thickness of the walls of such furnaces. Made of alloy steel with a high level of resistance to deformation during prolonged heating, the furnaces can be made of sheet steel 4-5 mm thick.
If the stove is installed in a small country house and you plan to use it only in the fall or early spring during rare visits to the site, you can make a homemade stove from a pipe or gas cylinders with a convection system. This design is cheap and can heat the house for a long time.
For garage
For a garage, using expensive heat-resistant or heat-resistant steel is an unaffordable luxury. This stove is used for a short time and not very often. Therefore, by making a stove from rims or sheet metal, 3-4 mm thick, you can easily solve the problem of heating a garage space.
Preparatory process
Having chosen what to cover the red brick stove in the house with, additionally purchase tools for work, clean and prepare the surface.
Main events:
- clean from dust and dirt,
- putty the cracks,
- remove chips.
On a note ! A folk method that will help get rid of minor flaws is to apply a mixture of egg white and homemade milk to a warm oven.
Inventory and additional building materials:
- dye;
- roller, brush, spray gun or compressor;
- tools for cleaning uneven surfaces (soft sandpaper);
- protective clothing: gloves, goggles, mask;
- rags.

Important ! In the room before work, the furniture, floor, and walls are covered.
Volumes and price
The choice of the size of a can of heat-resistant paint depends entirely on the volume of surfaces, as well as on the consistency of the paints.
Be sure to consult with sellers on this matter. The smallest jar is 0.2 liters, the largest is 12 liters. As for the price, the cheapest ones are decorative heat-resistant paint. However, keep in mind that the permissible temperature limit is only 200 degrees, which is not suitable for work carried out on parts that are close to the heat source. The most expensive are paints with aluminum shavings. If you are painting a flat and small surface, you can take paint in a spray can. Date: September 25, 2022
Painting
After choosing what to paint the stove in the house with, purchasing materials, preparing the surface, they put on protective clothing, take the tools they are going to use, and begin the painting process.
Step-by-step instruction:
- Close windows and doors to prevent drafts. Air currents will increase the likelihood of dust and small particles settling on the painted surface, which will negatively affect the appearance of the stove after complete drying.
- Thin the paint first if it is thick. Some experts recommend filtering the substance through cheesecloth to make sure that there are no garbage elements in it. This is also important if you decide to use a spray gun, so that the operation of the device is not hampered. This is also necessary when using paint of questionable manufacture.
- Regardless of the type of tool that is used, the work involves a certain algorithm for applying the composition: first the edges are processed, then the depressions and inconvenient places, then the main area.
Principle of operation
The operating principle of stoves operating on wood and electricity is based on the possibility of automatically turning on electric heating elements when the temperature drops (after solid fuel burns out). This happens as follows:
- Kindling and heating of the stove is carried out using firewood. Since the firebox is located at the bottom of the device, it transfers heat from the burning wood to the upper part of the device - to the heat exchanger. An increase in coolant temperature is detected by a sensor installed in the system line;
- when the temperature begins to drop due to fuel burning, the electrical circuit is automatically closed and electric heaters are connected to operation;
- from this moment on, the specified coolant temperature parameters are maintained by the heating elements, based on the readings of the air or water sensor;
- when loading the next batch of solid fuel, the electrical part is automatically switched off, as the coolant is heated
- already from the side of the combustion chamber.
This transition from wood heating to electric heating and vice versa ensures continuous heating of water in the heat exchanger, which allows you to maintain the optimal temperature in the house around the clock.
Wood and electric stoves come in two types:
- single-circuit - connected to the heating system and used only for heating;
- double-circuit - designed to heat the coolant in the heating system and hot water for domestic needs.
Recommendations from experts
The main task of the paint is to create an attractive appearance for the brick and protect the surface. No matter how high-quality the product is, over time cracks appear on the painted layers. This is a common decomposition reaction of the substance, but the period can be increased if the painting is carried out correctly and you take into account the advice of experts:
- The correct choice of what paint to paint the brick stove in the house is the main point that will eliminate minor nuances in the future. You should not buy cheap products. Such savings will require double costs in the future.
One of the ways to dilute paint in a separate container Source sdelalremont.ru
- If the paint is too thick, then it must be diluted only with a solvent.
- The density of the fresh substance should be kefir mass. This composition will not require dilution and will not spread during application.
- To increase the strength of the mixture at home, it is recommended to add 40-50 g of table salt per jar. It is important to first dilute it in warm liquid.
- If there are old layers of paint or lime on the stove, they should be removed. The limescale composition can be easily removed with water, and soft sandpaper can be used to remove paint.
- When purchasing brushes, you should not save money on them. It is better to buy a wide tool with natural bristles. When purchasing them, you should check them and touch the fibers. They should be soft but elastic.
- If you decide to use a roller, it should be made of foam rubber or short-pile fur.
- Many paint manufacturers write on the packaging that it is enough to apply one coat of paint, but experts advise working in three stages. First, a “rough” layer is applied, then the main one, and only after that the finishing layer.
Applying the first layer Source gidpokraske.ru
On a note! Drying thoroughly and applying additional layers will not only increase durability, but also deepen the color.
- Do not mix several types of enamels. It is prohibited to apply paint and varnish without first preparing the surface.
- Before buying paint, it is better to calculate the oven area to find out how much dye to purchase. This will save money.
After completing the work, it is better to close the room for a day and, if possible, not enter there. After 24 hours, you can already go into the room to check the condition of the stove and open the windows for ventilation. When choosing what to coat a brick oven with and with what tools, pay attention to all types of paints in cans or bottles, except those in aerosol cans. The composition sprayed with their help lies unevenly on the surface of the oven, and additional layers will lead to differences in shade.

Preparing the oven surface for painting
The process of preparing the stove for painting is simple and straightforward, but it must be carried out in full, otherwise the consequences will be dire. It is important that pure metal remains under the paint layer without any additional impurities.
The process looks like this:
- Thoroughly clean the surface with a wire brush.
- Remove remaining oxides with a solution of sulfuric acid with a concentration of 5%.
- Wash off the acid with a mixture of laundry soap.
- Degrease the metal surface using any available method - usually a solvent.
- Paint the surface with paint.
There is nothing complicated in the process itself, but you should pay attention to the details, since this is where mistakes are made. This process may not seem like a big deal, but if you don't do it, the paint will start to fall off soon enough!
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.

Fireplace decorating techniques
To stylize the design, you can use a technique such as highlighting the seams. The fact is that masked seams look uninteresting, while highlighted seams look unusual and creative. For standard brick-colored masonry, sandy, yellowish or white paints are usually used, which are applied to the seams using a thin brush. If there is no paint, mix turpentine and varnish in equal proportions, add a drop of gouache and use the composition in the same way.
You can also decorate the fireplace in other ways:
- paint a pattern on the front surface of the building;
- make a drawing using a stencil;
- paint metal elements in a contrasting color;
- create an imitation of wear and aging on the surface of the masonry (for example, make translucent strokes with lighter paint).
Contrasting design
There is no need to be afraid of experiments. Even with your own hands, you can completely transform an old fireplace and turn a banal design into a chic and sophisticated interior decoration.
Briefly about the main thing
Building a brick stove in a house or country house is far from the final stage in decorating a room. The stove structure also needs to be coated with paint.
Before decorating the structure with paints and varnishes, you should seal the cracks, treat the joints and clean up the irregularities. If you don’t figure out what paint to paint a brick stove with or don’t carry out additional surface treatment before painting, very soon the brick will begin to crumble.
The stove can be painted with polyurethane or silicone paint; the most budget-friendly method is ordinary lime whitewash.
It is important to follow the painting instructions: first treat hard-to-reach places and depressions with the composition, and only then apply the substance to the main area.
Chalk based whitewash
Chalk is an inexpensive natural material that is easy not only to apply, but also to wash off. Using chalk you can get a rich white color, but every time you touch the stove it will leave white marks on your clothes. For whitewashing, chalk is used in powder form, which is sold in hardware and construction stores. When diluting chalk, do not be afraid of the gray tint of the solution - after drying, the stove will become crystal white!
The chalk solution may have a gray tint, but the dry oven will be snow-white
To prepare the solution per liter of water, take 800 grams of dry chalk, but stove makers advise using skim milk instead of water, and adding natural laundry soap and wood glue for strength.
First, one and a half kilograms of sifted chalk are diluted in 3 liters of milk, after which the mixture is heated and a piece of grated soap and 100 grams of wood glue are added, continuing heating until the ingredients are completely dissolved
It is important to prevent the liquid from boiling! Before whitewashing the stove, the solution is filtered through cheesecloth and applied to the surface while warm.
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.
