Fire-resistant silicone paint does not melt at temperatures above 650 degrees and is often used in painting old barbecues.
Peculiarities:
- corrosion resistance;
- excellent adhesive properties;
- fire protection.
Thanks to its unique composition containing composites and heat-resistant glass, heat-resistant paint is resistant to temperature changes. Binder particles, special pigments and fillers determine the temperature range that requires attention to preliminary surface preparation and adherence to painting technology. If it contains zinc powder, the painted surface will withstand + 500 degrees. And if it contains titanium dioxide, then the maximum exposure rate is + 1000 °C.
Video description
This video shows what materials to gather for painting and how to paint a grill.
Many of these heat-resistant paints emit gases that are designed to minimize the spread of fire to nearby areas and surfaces. And other fire-retardant paints create a protective charred coating that covers the main material of the grill for a limited period of time. The choice of product and paint depends on the required level of safety and the material from which the surface is made.
Factors to consider when choosing fireproof paint
What factors need to be taken into account:
- intended purpose;
- compound;
- metal operating conditions;
- temperature Range;
- color stability;
- application characteristics.
Attention! Application characteristics should be the main factor when choosing heat-resistant paint for a barbecue. These coatings require a relatively thin film to remain intact at high temperatures without cracking.

How to paint and why won’t regular dye work?
The paint must be heat-resistant, i.e. withstand high temperatures (up to 600-1000 degrees Celsius), while not losing the aesthetics of appearance, not melting, not cracking, not flaming. To do this, special components are added to it, which give the coating protective properties when in contact with fire or other hot substances.
Conventional dyes do not have such advantages, so it is not rational to use them. When such paints are exposed to fire or high temperatures, the color of the coating will change. It may crack or completely come off the surface being treated.
Interesting: heat-resistant paints for metal are completely safe. When exposed to high temperatures, the dye does not release harmful substances. In this case, the coating remains the same as it was originally.
Painting a barbecue in 5 stages
The grill can be painted with heat-resistant paint in 1 day in 5 stages:
- Cleaning from contaminants, wash with water and detergents.
- Dry and wait until completely dry.
- Choose the optimal place, protected from rain and wind.
- Paint the grill using paint on the outside. It is advisable to use an aerosol.
- Checking the results and correcting errors.
It is necessary to paint in sunny weather, away from bodies of water and precipitation. Before painting, select paint, check the expiration date and functionality of the aerosol device.
Attention! Experts recommend using silicone and multipolymer enamels for painting metal barbecues.
How else to protect a metal grill from rust?
A procedure such as oxidation or bluing can also protect a metal product. It is performed in factories; it is not easy to carry out a similar procedure at home. You can really do this with your own hands only with collapsible structures.
First, all parts are immersed in a 5% sulfuric acid solution for 5 minutes. After this, an aqueous solution with soap shavings is prepared, in which the parts are boiled for 10–15 minutes. After this treatment, the parts are not wiped or dried. They are treated with caustic soda (caustic soda) heated to 100°C. The grill should be kept in the solution for at least 2 hours. The parts can then be removed and allowed to dry.
After this treatment, a strong film is formed on the grill, thanks to which it will no longer burn. There is no risk of rust for the oxidized product. True, this method requires a lot of effort, so it is much easier to paint the product.
Thus, by choosing one paint or another, you can significantly improve the appearance of your favorite cooking product. I recommend watching the following video to take into account the experience of those who have already done this.

Useful tips for using heat-resistant paints
When choosing black heat-resistant paint for a barbecue, you need to know the material of the surface to be painted. The special properties of different paints help protect not only metal coatings, but also concrete, brick, asbestos and plastered structures. The heat resistance of a coating is related to the maximum permissible temperature at which the dried paint retains its protective properties against weather influences for a long time. This information is usually found on packages and cans.
The color palette of heat-resistant substances also depends on the temperature range. For example, black, graphite and silver heat-resistant paints are suitable for painting barbecues and fireplaces. Gray and white heat-resistant paints are designed for piping and metal fireplaces. The service life of the protective coating depends on compliance with the application technology specified in the manufacturer's instructions.
Preparation
Separately, I would like to note that a barbecue cast from cast iron, like one made from stainless steel, does not require a protective coating. Also, you should not paint thin-walled barbecues, the walls of which quickly deform - because of this, the paint will still crack and crumble, and you will only waste time and money.
So, what do we need for painting:
Soap solution made from powder or detergent.
Acetone or other solvent for degreasing the surface.
A respirator and gloves for yourself, oilcloth or film to protect the work area from paint.
A metal brush or drill with a sanding attachment if there is already rust on the walls of the grill. If the design is new, skip this point.

Application of heat-resistant paint for barbecues
The resistance of the coating to temperature changes directly depends on the thickness of the layer of gray heat-resistant paint.
Resistant paint lasts 1-2 years and does not deteriorate due to weather influences Source pechiexpert.ru
To achieve a positive result, 1-3 thin layers are enough. A thick coating provides reliable protection against corrosion, but reduces the temperature range. Therefore, you can use a specialized anti-corrosion primer and coat the surface of the grill with heat-resistant paint. Apply the composition with a roller, brush or spray, avoiding the appearance of stains and carry out the painting yourself in compliance with safety rules.
Processing of products with non-metallic components
Combined structures, in which a metal brazier is used in tandem with a brick casing, also require additional protection. Heat-resistant and moisture-resistant varnishes can be used here; the only vulnerability is their inability to withstand low temperatures.
Fat impregnation based on an oily substance exhibits excellent frost-resistant properties. Such a solution is not afraid of temperature changes, but during operation it gradually becomes thinner and needs regular renewal.
Briefly about the main thing
The paint for the barbecue is selected in accordance with the materials of the barbecue and must be resistant to weather conditions. The main goal when choosing paint is to extend the life of the fryer and improve the appearance of the device. The choice of paint must be approached responsibly; among the variety of coloring substances, you can easily make a mistake and make a bad purchase. And most importantly, take care of safety; the paint must withstand temperatures of 600-700 degrees. Therefore, you need to carefully explore the possible options and purchase a quality product for painting your barbecue.

Safety precautions when painting
If you want to achieve the perfect effect when painting a structure, use the recommendations and safety rules. So, remember the following:
- It is better to paint with an aerosol when there is no wind outside.
- It is necessary to paint the grill from the outside.
- After cleaning the surface from dirt, you can rinse it and let it dry completely.
- When painting, it is necessary to create such conditions so that when drying, dust particles do not fall on the surface. Otherwise, you will be disappointed with the result of your work.
In conclusion, it should be noted that the process of painting a barbecue is not as tedious as it might seem. But it should be taken seriously. You need to choose a suitable coloring agent that meets all the main requirements. Then, prepare the surface itself. Apply a couple of layers, first allowing them to dry completely. That's all!
Follow the rules so that your grill looks beautiful and does not deteriorate for a long time. The paint for the barbecue must withstand almost any temperature and protect parts from corrosion and burning. The choice of coatings is huge, each has its own characteristics. When purchasing, proceed from your needs, and also find out more information about your model in advance.
