Dispensed from a 10.3 oz cartridge, it is especially suited for repairing cracked and chipped firebrick, tuck-pointing mortar into damaged masonry joints, and restoring the integrity of masonry-to-masonry connections. Once heat-cured, the material achieves a hardness and durability comparable to firebrick itself. It withstands temperatures up to 2,000 degrees F (1,093 degrees C) and meets the ASTM 136-79 flammability test standard.\u003c\/p\u003e\u003cp\u003eThis refractory mortar is used in residential and light-commercial applications wherever firebrick or masonry components are exposed to sustained high heat. Common installation scenarios include fireplace firebox repairs, wood-burning stove liners, and chimney breast tuck-pointing. The cartridge format is compatible with standard caulking guns, making it practical for targeted repairs without mixing bulk mortar. It is typically applied by fireplace technicians, masons, or HVAC service techs performing firebox maintenance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWithstands temperatures up to 2,000 degrees F after heat curing\u003c\/li\u003e\n\u003cli\u003eBuff color blends naturally with standard firebrick and masonry tones\u003c\/li\u003e\n\u003cli\u003e10.3 oz cartridge dispenses with a standard caulking gun — no mixing required\u003c\/li\u003e\n\u003cli\u003eDurable as firebrick once fully heat-cured\u003c\/li\u003e\n\u003cli\u003eMeets ASTM 136-79 flammability test requirements\u003c\/li\u003e\n\u003cli\u003eSuited for crack repair, chip filling, and tuck-pointing masonry joints\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style repair mortar for use with standard firebrick and refractory masonry assemblies in residential and light-commercial fireplaces, fireboxes, and wood-burning appliances.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eAllow the firebox or appliance to cool completely before applying refractory mortar. Clean the repair area of loose debris, dust, and old mortar before dispensing. Follow the manufacturer cure schedule, which typically requires a controlled low-heat initial cure before bringing the appliance to full operating temperature. This product should be installed by a qualified mason, fireplace technician, or HVAC service professional familiar with refractory materials and applicable local codes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNet Volume\u003c\/strong\u003e: 10.3 oz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Buff\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Temperature Rating\u003c\/strong\u003e: 2,000 degrees F (1,093 degrees C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlammability Compliance\u003c\/strong\u003e: ASTM 136-79\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 12 per case\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 15 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: IMPERIAL MFG GROUP USA INC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: KK0296-A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPERIAL","offers":[{"title":"Default Title","offer_id":51562283761970,"sku":"KK0296-A","price":76.46,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3799db9044a85b98e067f2caec93e097.jpg?v=1786474647","url":"https:\/\/voomisupply.com\/products\/imperial-kk0296-a-buff-mortar-cartridge-10-3-oz-firebrick","provider":"Voomi Supply","version":"1.0","type":"link"}
