Kraken Bond High Temperature Black Fireplace Sealant 12-Pack - 2732F

In this review the Kraken Bond High Temperature Black Fireplace Sealant is evaluated as a practical choice for homeowners and technicians who need a reliable, high-heat sealant for fireplaces, stoves, chimneys and ovens. The single biggest reason to consider it is its Class-A fire rating and stated resistance to temperatures up to 2732F, which addresses the core safety concern for high-heat sealing jobs. The review looks at ease of use, surface compatibility and durability so readers can decide if this 12-pack suits their repair or installation project.

Key Features

• Class-A Fire Rated: Provides certified fire resistance for critical joints and seams, reducing the risk of sealant failure in extreme heat situations.
• Withstands Extreme Heat: Rated to resist temperatures up to 2732F, making it suitable for fireplaces, stoves, chimneys, ovens and high-temperature HVAC applications.
• Effortless Application: The caulk applies smoothly with a caulking gun and can be smoothed with a putty knife or rubber scraper for a clean finish.
• Easy Cleanup: Uncured material cleans up with water, which simplifies tools and workspace cleanup after application.
• Multi-Surface Adhesion: Bonds to brick, stone, concrete and metal so it can be used across common materials found around fireplaces and stoves.
• Low Odor and Low VOC: The low-odor, non-toxic formulation is intended for indoor use with ventilation, improving the user experience during application.

Who It's For

The sealant is best for homeowners, masons, and HVAC or stove technicians who need a high-temperature solution for sealing joints in fireplaces, chimneys, wood or pellet stoves and oven surrounds. The 12-pack format makes it practical for multi-point jobs or for professionals who prefer keeping a ready supply on-site.

Those who need a flexible, long-term exterior sealant for constant wet exposure should look elsewhere; customers reported instances where cured product can be affected by heavy exposure to rain. For small single-use home touchups, a smaller tube count might be a more economical choice.

Pros & Cons

Pros

• High certified heat resistance gives confidence when sealing around active fire sources.
• Adheres to common materials like brick, stone, concrete and metal for versatile use.

Cons

• Some users reported mixed long-term durability outdoors where heavy rain exposure caused loss of adhesion in certain installations.
