Before you begin painting, it is essential to properly prepare the surface. Make sure the surface is clean and free of any dirt, grease, or rust. You can use a wire brush or sandpaper to remove any rust or loose paint. Once the surface is clean, wipe it Down with a damp Cloth to remove any remaining debris.

Next, it is important to protect any areas that you do not want to paint. Use painter’s tape and newspaper to cover any areas that you want to keep paint-free. This will help ensure clean lines and a professional finish.

Shake the can of Rust-Oleum High Heat Spray Paint vigorously for one minute before you begin painting. This will help ensure that the paint is properly mixed and ready to apply. Hold the can 8-12 inches away from the surface and spray in a steady back-and-forth motion. Be sure to overlap each pass slightly to ensure even coverage.

Apply the paint in thin, even coats to avoid drips and runs. It is better to apply multiple thin coats than one thick coat. Allow each coat to dry for 10-15 minutes before applying the next coat. This will help prevent the paint from running and ensure a smooth, even finish.

After you have applied the final coat of paint, allow it to dry for at least 24 hours before exposing it to high heat. This will give the paint time to cure and adhere properly to the surface. Once the paint is fully cured, it will be able to withstand temperatures up to 1200\u00b0F.


If you are painting a grill or other cooking surface, it is important to cure the paint before using it. To do this, heat the grill to 400\u00b0F and let it cool down completely. Repeat this process three times to fully cure the paint and ensure that it is safe for cooking.

In conclusion, Rust-Oleum High Heat Spray Paint is a durable and reliable option for protecting metal surfaces from high temperatures. By following the proper instructions for applying this spray paint, you can achieve a professional finish that will last for years to come. Remember to properly prepare the surface, protect any areas you do not want to paint, shake the can before use, apply thin, even coats, and allow the paint to cure before exposing it to high heat. With these simple steps, you can enjoy a beautifully painted surface that will stand up to the heat.
