This 10 oz cartridge delivers a refractory-grade seal that withstands temperatures up to 2,000 degrees F, making it suitable for high-temperature sealing and patching applications. It sets rock hard when fired, providing a durable, long-term bond around heat-producing appliances. Water cleanup keeps the job site manageable during application. Licensed contractors and fireplace installers working on residential heating appliances will find this a code-appropriate choice where non-combustible sealing is mandated.\u003c\/p\u003e\n\u003cp\u003eThis mortar sealant is designed for patching and sealing around fireplaces and wood burning stoves installed in wood frame construction. It is suited for residential applications where building codes or inspection requirements call for an ASTM E 136 non-combustible sealant at penetrations, joints, or gaps near high-heat appliances. The silicate cement formulation bonds well to masonry, brick, and metal surfaces commonly found in fireplace and stove installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWithstands temperatures up to 2,000 degrees F for use near fireplaces and wood burning stoves\u003c\/li\u003e\n  \u003cli\u003eNon-combustible silicate cement formulation meets ASTM E 136 requirements\u003c\/li\u003e\n  \u003cli\u003eSets rock hard when fired for a durable, long-lasting seal\u003c\/li\u003e\n  \u003cli\u003eSuitable for patching and sealing gaps, joints, and penetrations around high-heat appliances\u003c\/li\u003e\n  \u003cli\u003eWater cleanup simplifies application and tool maintenance\u003c\/li\u003e\n  \u003cli\u003ePackaged in a 10 oz cartridge for standard caulk-gun application\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in wood frame construction applications where an ASTM E 136 non-combustible sealant is required, including patching and sealing around fireplaces and wood burning stoves.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed contractor or qualified tradesperson familiar with fireplace and solid-fuel appliance codes, including applicable NFPA and IRC requirements. Power down or fully extinguish and cool any appliance before applying sealant to surrounding surfaces. Apply using a standard caulk gun and smooth with a wet tool before the product skins over.
