Kraken Bond High Temperature Black Fireplace Sealant 2732F - Fast Dry

In this review of the Kraken Bond High Temperature Black Fireplace Sealant 2732F, the bottom line is clear: this two-pack of 10.1oz tubes is aimed at homeowners and installers who need a reliable, high-heat joint sealant for fireplaces, stoves, chimneys and ovens. The single biggest reason to buy is its certified Class-A fire rating and ability to withstand extreme temperatures up to 2732F, which offers reassurance when sealing areas exposed to direct or radiant heat.

Key Features

• Class-A fire rated: Certified fire resistance gives confidence for use around fireplaces and chimneys where safety matters most.
• Extreme temperature tolerance: Withstands temperatures up to 2732F, so it holds in high-heat applications such as ovens, stoves and pellet stove piping.
• Multi-surface adhesion: Bonds to brick, stone, concrete and metal, making it useful for a variety of high-heat repair and sealing jobs.
• Easy application and cleanup: Smooths with a putty knife or rubber scraper and the uncured material cleans up with water for simpler finishing.
• Low odor and low VOC: Formulated for indoor use with reduced fumes, so it is more pleasant during application with proper ventilation.
• Durable, crack-free finish: Designed to cure without fragmentation or cracking to maintain long-lasting seals in heated assemblies.

Who It's For

This sealant suits homeowners, masons and HVAC technicians who repair or maintain fireplaces, wood and pellet stoves, ovens, and chimneys and who need a product rated for extreme heat. The two-pack format is convenient for small projects or for keeping a spare on hand for ongoing maintenance.

Those who require a flexible, paint-ready sealant for decorative surfaces will appreciate the paintable, low-odor formula. However, users who expect permanent adhesion in constantly wet outdoor conditions should be cautious, as some customers reported washout in heavy rain and mixed results on long-term durability in exposed locations.
