Despite the popularity of finishing ovens with ceramic tiles, frequently performed and painting brick heaters. This is due to the variety of problems that can be solved painted heater surfaces, if choose the right paint composition.
High-tech materials for painting brick kilns today produces enough. In addition, so far successfully used solutions manufactured independently according to old recipes, which age is measured in centuries.
To the result of paint heating unit was successful and maintained as long as possible, take a closer look paint compositions for industrial manufacturing, united on the characteristics of the group "paint ovens and fireplaces. "
Functions paint brick heater
Coloring stone heating device is performed in the following order:
- protection soaking furnace from the surface dirt and wear - of brick dust on contact with brickwork;
- facilitating daily care, that is, to maintain the required sanitary and aesthetic conditions;
- upgrade the decorative design of the unit;
- adapting the design of the heating device to an existing interior.
If bricklaying performed without sorting by color stone, the color of the housing heat-resistant paint (paint material) one or more colors correct the situation. However, even the finished facing brick furnace is transformed after application, for example, colorless paint, succulence imparting a matte finish and masonry.
Requirements for the stove painting structures
The main factor determining the requirement for coating materials for the furnace device, is their high temperature operation.
Important! Ranges of temperatures after heating at the various heater elements (brick, contacting them with iron devices steel furnace body) is different. In this thermal paint furnace withstanding the operating temperature of the metal elements of the machine, on the other characteristics (elasticity, adhesion) is often not suitable for application on brick building, the heating is much smaller.
By degree of resistance to high temperatures of coatings divided (in the direction of decrease) in fire-resistant, heat-resistant and heat-resistant.
refractory protection paint for furnaces used to protect metal parts from corrosion industrial units when exposed to open flame, corrosive combustion products and can withstand temperatures up to 1800 0FROM. Such materials are expensive, but in everyday life are not widely used for another reason - their highest potential heat resistance when used in devices for heating is still not demand.
Heat-resistant paint household ovens used for coating metal parts brick furnace heaters and steel towers. Temperature Heat Resistant coatings applications, depending on the species, is 600 - 1000 0FROM.
For staining stone housings furnace heaters and flues (brick seams solution) is applied thermally paint for furnaces and fireplaces intended for application to the surface working temperature - 200-400 0FROM. In addition to colors, in this subgroup also includes a heat resistance and varnishes 250-450 0FROM.
On a note. With high-temperature inks for fireplaces and stovesshould not be confused flame retardants, with a similar name with a different purpose - the protection of the base covered by the fire outside.
In addition to resistance to high temperatures, heat-resistant paint furnace bricks must have other characteristics:
- safety - by heating not release harmful substances in the air;
- sufficient thermal conductivity - not prevent heat transfer between the surface of the furnace and the air;
- resistance to household chemicals - to maintain the physical properties and aesthetics after repeated daily care procedures;
- elasticity - not form cracks during temperature changes;
- Coverage - provide monophonic coverage of the substrate is not more than three layers.
Types of coating materials for buildings of brick kilns
The range of heat-resistant paint formulations available today, both domestic and foreign manufacturers, is wide enough to satisfy the demand user in any situation - whether brick heater impart a different color, is optimally suited to the interior, or to create a transparent protective layer, while maintaining a natural look masonry. If the surface is plastered unit - technology painting another, but there is a heat-resistant coating, and for this type of finish. What kind of paint or varnish applied, it depends on the decision of a question of aesthetics of the unit.
Let us consider these groups with reference to specific thermostable coatings.
silicone compositions
These solutions - are high quality mixture (paints, enamels, lacquers), manufactured based on organic resins and used, depending on the characteristics, both for external finishing works (building facades) and painting the internal elements of the interior, including - of stoves and fireplaces.
For the coating furnace devices of bricks used heat resistant silicone solutions (Not to be confused with moderately heat-resistant paint is used for exterior finishing and heat resistant up to 100 0FROM).
Finishing brick enclosure heater silicone compositions - a widespread solution due to affordable price range and the material the following advantages:
- high degree of adhesion to the surfaces of any billing;
- strength of the resulting membrane;
- moisture resistance;
- durability;
- High heat resistance in combination with the elasticity (200-250 cycles of heating-cooling).
The disadvantage of heat-resistant silicone coating may include the limited color gamut of the variety of solutions is due to the chemical composition and application place.
Application is made to the base with a brush, roller or spray after surface preparation - dedusting and heat-resistant primer priming composition, e.g., waterglass solution fosfogruntom or G-77.
Important! Use for dyeing brick brush or paint roller provides better adhesion of the composition applied to the substrate.
Compliance printed on the packaging of the application of paint to the oven instructions - the key to quality and long-lasting coverage.
Heat-resistant acrylic paint
This group is a dispersion (solid in liquid) acrylates of paints made with an aqueous or oil-based.
For coloring furnace or fireplace brick suitable both of these types of acrylic blends, but increasingly used in daily life Water-dispersion paints, calculated, depending on the species, on the operating temperature of 200 - 400 0FROM.
These heat-resistant coatings penetrate deeply into the pores of the coated base and create it on film strength, which resulted in a classification of them as enamels.
Applied to the surface with a brush, paint roller or spray and after thorough mixing, add water to desired consistency, the required number of layers - two, the drying of each layer - 24 hours, odors when painting no.
The color scheme acrylics wide, but no juicy pitch, and the effect of the additive compositions Kohler transient.
On a note. Brick surface heaters can be covered and normal, not heat-resistant acrylic emulsion, but the durability of such a finish is not high - about one year.
alkyd emulsion
Root "alkyd" of these coatings formed by fusion of two determinations: alcohol and acid (acid).
The binding of these emulsion composition (liquid in liquid) inks are alkyd varnish, the dye and the solvent, usually white spirit. Depending on the variety of coatings, can be present in solution marble or granite dust, antifungal and fire resistant additive.
Alkyd emulsion can be coated housings heaters of bricks, if the surface temperature does not rise above 100 0FROM. These coatings will enjoy richness and variety of colors, but the hardened film after application of the solution is much less elastic than acrylic compositions so bad with the heat expansion of the base and the end of the year of operation covered by a web of fine cracks, requiring replacement finish.
Important! When working with alkyd paints having a pungent odor of solvent, it is necessary to use personal respiratory protection and ventilation.
Thermal stability of alkyd paints enhance the addition of aluminum powder in them, but such compositions are not suitable for painting brick.

conclusion
The above-mentioned coating materials for furnaces and fireplaces - not the whole list of heat-resistant paints. Moreover, each group includes several species of solutions differing characteristics and application method.
In addition, if due to any reasons to buy paint for the furnace of bricks is not possible, you can use recipes independent manufacturing of paints - many owners are brick heaters known.
The main essence of the article
- Heat-resistant paint for brick buildings stoves and fireplaces are used not only to enhance the aesthetic finish of heaters, but also for defensive purposes.
- When choosing paint for the brick oven, you must determine the intended purpose, that is, what is planned do other than protect the base - change trim heater or emphasize performed upscale facing.
- When planning to paint the brick heating device, it is necessary to know the basic properties of the coatings manufacturer offers to later be disappointed unexpectedly low coating durability.
- A wide range of heat-resistant paint compositions there is an alternative - materials independent production, which are often inferior in functionality with a solution of industrial manufacturing.
