The sprayer leg is soldered into the can, so if the composition dries out, it will not be possible to replace the mechanism. Therefore, it is better not to leave partially used paint for a long time.

Rules for selection and use

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

Specific nuances in terminology

Many salespeople in their advertising campaigns are very frivolous with the terminology adopted for compositions that can be applied to surfaces with high temperatures. There is no normatively established gradation according to the correspondence between the name of the composition and its maximum permissible heating temperature.

However, three established terms are usually used:

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

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

Water jacket of a metal furnace. From the outside, it does not heat up above the temperature of the coolant, so high-temperature paint can be used to treat its surface

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

These paints are used for the following metal objects:

• sides and bottoms of furnaces;
• barbecues;
• pipes for exhausting combustion products;
• the junction of the water circuit pipes 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 interior design solutions.

Heat-resistant paint is designed to cover surfaces that are heated to temperatures above 650⁰C. First of all, these are cooking stoves and furnace fireboxes, as well as grates wood stoves and fireplaces.

Some types of thermal paint have an additional feature - fire resistance. This means that the painted surface may be in direct contact with the flame. Among household metal objects, this is relevant for the fireplace grate and the inside of the barbecue.

Theory and practice of thermal hardening

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

Sometimes, to protect metal products, a colorless varnish is applied to them. This type of coating also requires thermal hardening

It is after thermal hardening that neither oxygen, which causes the rusting process, nor moisture can penetrate under the enamel. Before this, the paint has only a decorative and, partially, protective function from physical impact.

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

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

Cannot be applied heat-resistant composition, which requires thermal hardening, on radiators 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 hardening process should take place at a constant temperature for 30-60 minutes. However, in practice, such “laboratory” conditions are impossible to achieve.

That's why wood stoves, barbecues and fireplaces are not heated to full capacity and their heating is gradually increased. Typically a test run takes 1.5-2 hours. Another option is heating with an industrial hair dryer.
