The sprayer foot is soldered into the can, so when the composition dries, the mechanism cannot be replaced. Therefore, it is better not to leave incompletely used paint for a long time.

Rules for selection and use

To choose the right paint, you need to determine the maximum surface temperature on which it will be applied. You also need to calculate the area and make a choice between a spray in a spray can and a liquid consistency in a jar. But there are still some rules you need to know.

Specific nuances in terminology

Many sellers in their advertising companies are very frivolous about the terminology adopted for compositions that can be applied to surfaces with high temperature. There is no normatively established gradation according to the name of the composition and its maximum allowable heating temperature.

However, three commonly used terms are commonly used:

  • high temperature;
  • heat resistant;
  • heat resistant.

High-temperature paints for metal include compounds that withstand prolonged surface heating up to 2000C. They are used for processing radiators and heating pipes, brick stoves and fireplaces. They are also suitable for automotive parts such as engine, muffler and exhaust system.

Metal furnace water shirt
Water shirt of a metal furnace. Outside, it does not heat above the temperature of the coolant, therefore, high-temperature paint can be used to process its surface

Heat-resistant compounds used for surfaces with temperatures up to 6500C.

Such paints are used for the following metal objects:

  • sidewalls and bottom of furnaces;
  • barbecues;
  • combustion exhaust pipes;
  • the junction of the pipes of the water circuit 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 solutions for interior decoration.

Heat-resistant paint is designed to cover surfaces that heat up to temperatures above 6500C. First of all, stoves and furnaces, as well as grate wood stoves and fireplaces.

Some types of thermal paint have an additional sign - fire resistance. This means that the painted surface may be in the direct flame zone. Of household metal objects, this is true for the fireplace grate and the inside of the barbecue.

Theory and practice of thermal hardening

Heat-resistant paint is inherently heat-resistant enamel. To create an impermeable barrier, it is necessary to perform the procedure of thermal hardening. In the process of heating the surface with the composition deposited on it, the polymerization of the layers occurs, after which the access of air to the painted metal is terminated.

Furnace painting with heat-resistant varnish
Sometimes, to protect metal products, colorless varnish is applied to them. This type of coating also requires thermal hardening.

It is after thermal quenching that neither oxygen, causing the rusting process, nor moisture can penetrate under the enamel. Prior to this, the paint carries only a decorative and, partially, protective function against physical impact.

Moreover, after creating an impermeable layer, the evaporation of the substances contained in the paint into the air of the room stops. Therefore, ideally, it is necessary to wait for the established period of complete drying, which is indicated on the label or in the instructions, and then immediately carry out the procedure of thermal hardening.

Typically, the temperature at which enamel polymerizes is 200-2500C. This leads to one common mistake often made by people who have leftovers after painting the oven.

Can not be applied heat resistant composition, which requires thermal quenching, on batteries 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 quenching process should take place at a constant temperature for 30-60 minutes. However, in practice such “laboratory” conditions are unrealistic.

therefore wood stoves, barbecues and fireplaces are not flooding at full capacity and gradually increase their heating. Usually a test run takes place within 1.5-2 hours. Another option is heating with an industrial hair dryer.

    Used heat-resistant paint from Tikkurila. I can say that the paint is normal, although it costs, of course, a lot. But, on the other hand, if you buy cheap paint, because of which later you have to repaint, it will turn out even more expensive. As they say, avaricious pays twice. And Tikkurila lays well, without spots, without any other problems. It has good durability. In general, I am satisfied.

    • Sergey Ivanushkin

      There is logic in your words, but Tikurilla is a very expensive helmet. And alright, there would have been no alternative at all, but our Elcon is quite coping with the task, having a significantly lower cost.

  2. I.I.I.

    C'mon, “Top 10”))) Some unknown Chinese colors. Tikkurila at a space price ... Where's the budget KUDO? Where is Certa which Lemax paints its boilers?
