Features and top 14 brands of heat-resistant paints for metal, instructions for use
Heat resistant, heat and high temperature resistant paint is used for metal and for painting concrete, plaster and brick surfaces. This is a special type of paints and varnishes with unique properties. Thermal paint is able to withstand heating from 200 to 1000 degrees Celsius. All types of these paint materials are plastic, that is, they expand with increasing temperature.
Features and characteristics of thermal paints
To paint surfaces that become very hot during operation, you need to purchase special thermal paints. These paints and varnishes do not crack or ignite when the temperature reaches 250 degrees Celsius and above.
The heat-resistant composition allows the paint not to change color for a long time. In addition, these products protect the painted surface from corrosion (exposure to water).
Heat-resistant paints contain organosilicon, epoxy, silicone or alkyd resins, which give the coating abrasion resistance, hardness and water resistance. According to their ability to withstand a certain heating temperature, thermal paints are divided into high temperature, heat-resistant, heat-resistant and fire-resistant. Each type of paint is intended for painting specific objects.
High temperature enamel is excellent for painting radiators, boilers, pipes, gas pipes. Heat-resistant thermal paint can be used to paint the outer walls of a barbecue, an oven. Heat-resistant enamel is used if the object is constantly heated to temperatures above 800 degrees Celsius.
Thermal paint is applied in 1-3 layers. For painting surfaces, rollers, brushes, paint sprayer are used. Thermal paint dries, depending on the composition, from 1 to 12 hours. The coating is smooth, hard, durable, it reliably protects the metal from corrosion, the painted surface from the effects of high and low temperatures, extends the life of the painted object.
Criteria for choosing temperature paints
When choosing a thermal paint, first of all, they pay attention to heat resistance indicators. For each object that heats up during operation, a different type of paint is produced. It is forbidden to use the purchased thermal paint for other purposes, that is, to use it on objects that heat up weaker or stronger than indicated in the instructions.
Types of thermal paints:
- high temperature (up to 250 degrees Celsius) - for radiators, heating objects, stoves, fireplaces, car engines;
- heat-resistant (up to 400-600 degrees Celsius) - for stoves, barbecues, pipes for the removal of combustion products;
- heat resistant (over 800 degrees Celsius) - for hobs, stove inserts, fireplace grates, barbecue interiors;
- flame retardant (over 1000 degrees Celsius) - for painting surfaces that can withstand open fire.
Review of the best brands
LKP manufacturers produce many heat-resistant paints. The technical specifications of each thermal paint must indicate the maximum heating temperature. It is this that serves as the main criterion when choosing paints.

Subtleties of application
Each thermal paint contains low-toxic components with a pungent or weak odor, which give certain properties to these products. It is recommended to work with paint in a respirator, rubber gloves, with open windows. It is recommended to ventilate the room after heating the object to be painted. It should be remembered that the choice of paint depends on the heating temperature of the object to be painted. Batteries and pipes that do not require heat curing are painted only with high temperature enamel.
Objects exposed to very high temperatures during operation must be hardened after painting. Immediately after painting, thermal paint has only decorative properties and partially protects the painted surface from mechanical damage. Such enamel acquires strength only after heat hardening. During the heating process, the deposited coating polymerizes.
After thermal hardening, such a paint hardens completely and no longer releases toxic substances. The hardened composition protects the surface for a long time from the effects of high temperatures, water, steam, oils, gasoline, abrasion and mechanical damage. For this reason, it is recommended to heat the object painted with thermal paint up to + 400 ... + 800 degrees Celsius.
Additional tips and tricks
When painting radiators and heaters, ordinary high-temperature stoves, pipes and paints are used. To paint a solid fuel stove, it is recommended to purchase a refractory compound.It is forbidden to use paints on heaters that are not resistant to high temperatures. Such paint can ignite during operation and cause a fire.
Before buying thermal paints, calculate its consumption.The surface to be painted is calculated by multiplying the length of the surface by its width. It is advisable to immediately purchase the necessary amount of paint to paint in the desired color.
