Fireproof paint reduces the impact of high temperatures on structures, increasing the fire resistance, which can last up to 1 hour or more. Usually structures are subject to protection, the deformation of which leads to loss of strength and destruction of buildings. The use of thin-layer coatings for protection is regulated by the fire protection code.

If we are talking about fire-retardant thin-layer paint, then it is applied up to 4 mm thick. On sale you can also find thick-layer compositions, which are represented by mastics and pastes. They are applied in a layer with a thickness of 8 mm or more.

Selection by manufacturer

If you need a fireproof paint, you can choose a composition that swells when exposed to high temperatures. Such mixtures have approximately the same composition, but differ in the nature of additives and fillers. More expensive materials provide a high and lasting degree of protection. Experts do not give special recommendations for selection, so you should proceed from the technical characteristics of fire resistance.

It is important to pay attention to manufacturers who have been on the market for a long time and have managed to establish themselves on the positive side. In a sufficient assortment, the modern industry produces the described materials, among the most popular are:

• Pyrex;
• DEFENDER;
• Krause;
• "Iceberg";
• Orgax.

For reference

Before making a purchase, you need to remember that fire-resistant paint can be water-soluble and solvent-borne. In the latter case, we are talking about mixtures that are made on the basis of a solvent. They are a little more expensive and not as comfortable to work with, but the advantage is more outstanding performance.

Review of refractory paints: PIREX blend

This mixture can increase the fire resistance up to 120 minutes. The composition is characterized by low consumption. An aqueous dispersion of synthetic polymers acts as a binder. Dilution is allowed, but the volume must not exceed 15% of the total mass. It is important to remember that this refractory paint must be used under certain conditions, they are expressed in compliance with the ambient temperature. You can start working when the thermometer has risen above +10 ° C, while the relative humidity should not exceed 85%.

In order to achieve an average layer thickness of 1 mm without taking into account losses, it is necessary to apply on 1 m2 1.65 kg of paint. At temperatures within 20 ° C, the layer will dry in 12 hours, this is the period that must be maintained before proceeding with the application of the next layer. This refractory paint for metal must dry completely in a maximum of two days, the minimum period of time is 36 hours. After drying, it will be possible to obtain a matte white layer that will protect the structure for up to 10 years. This is true if the coating is not protected from above, otherwise the term will be extended to 15 years.

Reviews on fire-retardant paint brand "Crause"

According to buyers, Krause fire-retardant paint for metal is quite technologically advanced and durable. The coating can be used for 25 years. Consumers especially note environmental friendliness, because the mixture does not contain substances harmful to he alth. If necessary, the composition can be tinted in pastel colors, which makes it possible to achieve decorative effect. According to users, this fireproof metal paint is a one-component composition, water-dispersion based, which swells with increasing temperature.

It can be used for application on metal and steel structures in order to increase the fire resistance. Users like that this paint has a wide range of uses, because it can be used in industrial, residential and civil construction. Fire resistance reaches 90minutes. A structure protected by this paint can also be used indoors, where the relative humidity does not exceed 80%. In order to also achieve the quality of fire resistance, a protective coating should be applied, the thickness of which will reach 60 microns.

Overview of the features of Elcon heat-resistant paint for barbecues and stoves

This paint is refractory, the price of which is 181 rubles. per kilogram, designed for protective painting of equipment, stoves, heat pipes, barbecues and other surfaces. The thermal resistance of the layer will be from -60 to +1000 °C. Additional characteristics include resistance to aggressive environments, no need for pre-priming, the possibility of application at low temperatures, service life up to 25 years, low consumption, which is 350 g/m2, which correct if applied in two coats.

This furnace refractory paint has a fairly wide range of use, it has anti-corrosion properties, and can be applied to boilers, metal equipment, oil pipelines, and pipelines that will be operated in a wide temperature range. You can use the composition for painting indoors, because after drying the mixture does not emit toxic fumes. Enamel is also used to paint grills.

The mixture has unique protective properties that allow you to protect the surfaces of structures from moisture and hightemperatures. These include reinforced concrete, concrete, asbestos and brick foundations. When applied, you can improve the appearance of the object and maintain the quality of vapor permeability. enamel will not lose its properties even with increasing humidity and temperature fluctuations. Due to this, the paint can be used for equipment that will be operated in difficult conditions.

Additional Features

The above-described refractory paint for metal for barbecue is resistant to aggressive media such as stray currents, s alt solutions, petroleum products and mineral oils. The paint can be applied in an electrostatic field and when the temperature drops below zero.

Conclusion

If you need a refractory paint for a barbecue, then you can also turn your attention to Elkon products, which are used for anti-corrosion protection of metal surfaces operated in wet conditions and with possible temperature differences. Application of the composition can be carried out on the exhaust systems of cars, metal surfaces and engine parts, which will be exposed to temperatures up to 800 °C. Such refractory paint for barbecue is also called heat-resistant.
