Modern country cottages and apartments have fireplaces or stoves. The fireplace allows you to decorate the interior, and it also warms the room. In order for the stoves to look aesthetically pleasing in a modern design, they are painted. But this is a furnace that generates heat during operation, and how to paint it? It's simple: you need to use a special heat-resistant paint for furnaces. Let's look at what kind of paint it is, what features and characteristics it has.

Why paint stoves and fireplaces?

The painting of the furnace helps to prevent cracking in the brick and prevents the increase of already formed defects.

By painting, you can get a flat surface. Even painting improves heat transfer. Of course, this allows you to solve many problems. But, let's look at how to paint a brick stove in a house.

What painted before?

Previously, Russian stoves were treated with chalk and whitewash on a lime basis. The consistency of whitewashing should have been like liquid sour cream. Before starting to paint, the surface was treated - it was cleaned of dirt, dust and clay. The paint was prepared as follows: 40 g of salt, previously dissolved in water, were taken per 100 g of lime.

Whitewashing, despite the simplest composition, had high strength values. The only negative - the surfaces painted with such paint were white.

The stoves and fireplaces were also painted with chalk. It was pre-sieved through a sieve, then diluted with milk and thoroughly mixed. If the solution turned yellow, then blue was added. This paint was applied in several layers, and the surface had to be moistened with water. Then the first layer was applied, and after complete drying - the next.

What is used today?

Times have changed and nobody is preparing whitewash today. Modern owners of Russian stoves and fireplaces prefer other means. Consider each option in more detail.

Natural drying oil

As oven paint, natural drying oil is used - this coating does not change the color of building materials, but slightly changes the shade to the darker side.

Drying oil is most often covered in stoves in bathhouses. But, it has a drawback - the furnace, after it has flared up, can be operated no more than two or three hours.

Organosilicon paint

Along with drying oil, organosilicon paints for brick ovens are widely used. These compounds have many advantages:

  • high adhesion with any materials;
  • coating strength;
  • resistance to moisture;
  • high durability;
  • heat resistance (withstand more than 200 cycles of temperature changes).

Such paint for stoves and fireplaces is the best choice, moreover, affordable. The downside of this coating is considered only a small selection of colors.

Silicone Enamel

Alkyd based varnish

For painting fireplaces, PF-283 varnish is also often used. It is a mixture of alkyd resins, modified vegetable oils, fatty acids and other additives. The varnish is mixed with turpentine in equal proportions. This increases the strength of the coating. After drying, a glossy transparent and very durable layer forms on the surface.

Dyes, for example, dry gouache, can be added to the varnish to produce any color.

Heat resistant paint

The most popular option is the use of heat-resistant paints for stoves and fireplaces. The material has a huge number of advantages:

  • large color gamut;
  • it is a heat-resistant paint - it withstands temperatures up to 600 degrees;
  • the surface of brick ovens and fireplaces is reliably protected from oxidation;
  • the material is distinguished by increased characteristics of strength and wear resistance;
  • performance lasts more than 10 years.

Heat-resistant paint also has disadvantages, among which it is especially necessary to highlight the aggressive composition, unpleasant odors, and a long drying time. Due to the presence of toxic substances, you should carefully work with thermal paint.

The main characteristic of heat-resistant paint is resistance to high temperatures. The coating should protect the surface from moisture, steam, water. The metal surface coating protects against corrosion.

Which is better to choose?

Standard varnishes and paints for coloring will not work - the surface will become very hot during use. So how to cover the fireplace? It is necessary to use heat-resistant paint for a brick stove or fireplace. The composition of the coloring mixture contains special substances that prevent the loss of the characteristics and properties of the coating even at extremely high temperatures.

Refractory paint for fireplaces and stoves is able to withstand temperatures up to +650 degrees without loss of properties. Given that firewood can only heat the firebox to 300 degrees, this is an acceptable option.

First of all, when choosing a suitable paint material, look at the type of heating device. If the structure is metal, then the heating can vary in the range from 300 to 600 degrees. The temperature in the flame zone will be even higher.

An important requirement when choosing heat-resistant paints for furnaces is the possibility of using the material for interior work. If the oven is installed in a bath, the paint should provide protection against moisture. To paint surfaces heated to high temperatures, it is recommended to purchase heat-resistant, heat-resistant, and also refractory compounds.

But along with these materials there are so-called fire-retardant mixtures - these products are not suitable for a fireplace or stove made of bricks and metal. This coating will be covered with bubbles already when heated to 200 degrees. Heat-resistant paint for brick and metal stoves can be used at temperatures up to 600 degrees. Such compounds are suitable to paint a fireplace made of metal, brick or granite.

For the stove in the bathhouse in the country, it is best to choose special enamels that can withstand heating up to 800-1000 degrees.

Along with paints, modern manufacturers make various heat-resistant varnishes. They withstand temperatures well within 300 degrees. The surface painted with such varnish will shine with a glossy gloss, and the color will become brighter.

What to look for when choosing?

Choosing how to paint a brick stove, it is important to pay attention to not a few basic factors:

  • the paint must withstand high temperatures;
  • what is the composition consumption per 1 sq. m;
  • level of resistance of the coating layer to aggressive environments;
  • paint composition;
  • methods of application.

All materials for brick and metal surfaces existing in the construction market can be divided by composition and basis on the basis of which these products are created. So, they distinguish acrylic enamel, epoxy resin, silicon-based base and silicones.

Any of these materials has certain requirements: resistance to temperatures above 300 degrees, resistance to steam, moisture, cracking.

Paints of popular brands

Suitable paint for metal and brick for fireplaces is a silicon-containing mixture KO-168, 8101, 813. These products have all the characteristics. On the package must be marked that the mixture is heat-resistant. As a solvent, 646 solvent or turpentine are used. Brick surfaces are coated in two thin layers.

Another option is anticorrosion heat-resistant paint “Tserta”. Materials can be used for metal for stoves and fireplaces, as well as for brick. The compositions are sold in cans and spray cans. Assortment of colors - 12. By mixing the primary colors, you can get interesting shades up to gray.

How to paint a red brick oven so as not to spoil the noble color? To do this, choose Elcon silicone varnish. It is able to withstand temperature effects up to 250 degrees.

For metal fireplaces, a mixture of NEW TON is well suited. The composition can withstand temperatures up to 600 degrees. This product protects the metal from corrosion, has good elasticity, therefore it preserves the appearance of the surface, will not crack and deform under the influence of high temperatures.

Sometimes a surface painted with high-temperature paint needs additional processing. This is done on the basis of colorless varnishes KO-815 and KO-85. Heat-resistant enamels KO-813 are made from them, which are suitable for metal and brick.

How to paint fireplaces and stoves?

Now we know how to paint a brick or metal stove. There are many funds on the market. Let's look at how to paint a brick oven. The first step is preparing the surface.

The surface is carefully processed, cleaned of debris, grease and dust, and then smoothed using plaster compounds. Then remove fragments of clay, which is located between the bricks. The surface is finally prepared with a sandpaper for better adhesion.

Brick paint is applied in two or three layers. You can work with a brush, roller or spray. Experts recommend the use of funds in spray cans. But with a brush you can give an invoice. The roller will help distribute the dye more evenly.
