10 Best High Heat Paint For Fireplace 2025 in the United States

The Rust-Oleum 248903 Automotive High Heat Spray Paint is a solid choice for anyone looking to repaint or touch up parts of a fireplace that may be exposed to high temperatures. It excels with a very high temperature rating, being able to withstand intermittent temperatures up to 2000°F, which is ideal for areas like exhausts, manifolds, and headers. This makes it highly suitable for fireplaces where high heat resistance is crucial. The finish type is matte, which gives a sleek, modern look to the painted surface, and the color option available here is flat black, a versatile color that can match many different decor styles.

The application method is an easy-to-use spray can with any-angle spray technology, making it effortless to apply even in difficult-to-reach areas or at awkward angles. Additionally, it features a comfort tip to reduce finger fatigue during application. It dries to the touch in 30 minutes, which is relatively fast, though full curing time should be adhered to as per the instructions for the best results. Another strong point is its rust-preventive formula, which resists oil, gas, grease, and environmental elements like rust and salt, ensuring a durable and long-lasting finish.

This product covers up to 10 square feet, which is decent coverage but might require multiple cans for larger projects. This spray paint is highly effective for high-heat applications with added benefits like rust prevention and ease of use, though its coverage might be a limiting factor for very large surfaces.

The Rust-Oleum 270201 Specialty Silver High Heat Ultra Spray Paint is designed specifically for surfaces exposed to high temperatures, making it suitable for fireplaces, grills, wood-burning stoves, and engines. This 12-ounce can of paint provides coverage for up to 15 square feet, although users report practical coverage closer to 8 square feet. Its semi-gloss metallic finish adds an elegant look to any surface, while the silver color offers a classic aesthetic.

One of the product's main strengths is its resistance to rust, corrosion, and chipping, which ensures durability under high-heat conditions. The paint can withstand high temperatures, and its aerosol form makes it easy to apply, although it requires careful handling and cleanup with mineral spirits.

A potential drawback is its limited color option, as it is only available in silver. Manufactured in the USA, this paint doesn't require batteries and comes with a high customer rating, indicating satisfaction among users. However, it is noted that the paint is not water-resistant, meaning it's best suited for indoor applications or well-protected outdoor areas.
