The barbecue season is a whole ritual. Summer residents begin preparations a couple of months before it starts. Of course, the main attribute is the grill. This is an open brazier in which a fire is built, where food is then cooked on the resulting coals. As a rule, these are meat and vegetables.
If a trip out of town is spontaneous, then most often a disposable grill is used. After cooking kebabs, it burns out and is subject to disposal. But there are also stationary options that are used for a long time and often. This item requires careful care. One day, any owner comes up with a question: what kind of heat-resistant paint for a barbecue is suitable to extend its service life, not to quickly burn and not to be poisoned by toxic emissions and combustion products.

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.
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.
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.
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.
Protection of brick structure
Nowadays, it is fashionable to make not just metal barbecues, but brick or stone braziers. In addition to the fact that it is made of fire-resistant bricks, heat-resistant impregnation will not harm it, plus it will help protect it from bad weather. The treated surface is easy to clean from soot, grease and soot with your own hands.
A cheap option would be to use KO 85 varnish, but it can crack due to frost. An option that combines price/quality combination would be the use of impregnation for stoves and fireplaces. This composition is not afraid of frost because it contains an oil component. The downside is the need for re-processing every other season.
Another practical composition is a silicone water repellent for ovens. The mixture is endowed with water-repellent and antifungal characteristics and perfectly protects brick walls from grease. Moreover, it retains all available properties even at high temperature loads.

The resistance of the coating to temperature changes directly depends on the thickness of the layer of gray heat-resistant paint.

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.
How to paint
Before painting, you need to prepare the tool and the paint itself.
You will need something to clean off the rust. Of course, you can use a simple brush, but it’s better to take a drill or grinder with brush attachments.
You also need a solvent to degrease the surface. Acetone, white spirit and the like are suitable.
Read the instructions on the package.
Stir the ingredients in the jar until smooth. Lumps are not allowed. Shake aerosol cans vigorously.

Organosilicon composition
- Mechanical cleaning. It is necessary to clean the metal from carbon deposits, rust and old paint. Steel brushes will help you. Hand-held, for drills or grinders. Where the paint is particularly strong, use sandpaper.
- Degrease the surface; white spirit, acetone and the like will do.
- Painting. Apply the well-mixed paint in one layer. This works well with a roller, but a brush will also work. A sprayer will give an even more uniform layer, but you need equipment and a solvent to thin the paint (a suitable solvent is indicated on the package).
- Repeat application 2-3 times at intervals of 30 minutes to an hour.
Acrylic enamels
- Clean the grill down to the metal, as in the previous version.
- Shake the spray can vigorously.
- Apply coating evenly to surface. Avoid smudges and drops. We recommend using protective equipment (goggles and respirator).
- Apply 2-3 layers at intervals of 30 minutes - 2 hours.
- After the last layer has dried, warm up the grill according to the instructions for the paint. This usually takes 15 minutes.
Using a paper stencil and an aerosol can, you can decorate the grill with a pattern.
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.
