Masonry is a centuries-old craft, with updates over time adding a coating to its surfaces. Some forms of masonry like those used in fireplaces or areas with low humidity are designed to retain high heat. Read on to learn more about the best high heat masonry paint to use.

Without high heat masonry paint, several brick surfaces in places with low humidity will remain uncoated. Proper coating with high heat masonry paint prevents gradual cracks and imminent disintegration.

You can decide to use high heat masonry paints with primers, specialized cement, water-proofers, and so on. However, proper coating with a high heat masonry paint prevents heat penetration onto bricks. 

Different forms of high heat-resistant paint exist that are ideal for masonry surfaces. That’s why this guide recommends the best high heat masonry paints across categories.

Intumescent properties in this fire-retardant paint make it a great option for multiple high-heat surfaces. It comes with a sleek matte finish designed to retard heat spreading that might lead to surface wear and tear. 

The fire retardant paint is suitable for coating wood, plaster, cellulose, metal, and masonry. It also dries quickly, possesses a low odor formulation, and supports washing too.

Several paints will crack, split, or peel under intense heat, but the AW Perkins 1400 is in a different class. The non-peel paint comes in matte black and remains consistent under heat up to 1400°F.
