Imperial Kk0077-a Furnace Cement, Black, 8 Oz

Imperial Furnace Cement is a pre-mixed, black silicate ceramic cement formulated to seal and repair joints in furnaces, chimneys, and flue systems. This durable compound withstands extreme heat and bonds securely to metal and masonry surfaces, preventing air and gas leaks that reduce heating efficiency and safety. Whether you're installing a new furnace, resetting an oil burner, or repairing existing chimney joints, this cement provides a reliable, long-lasting seal.

The creamy, smooth texture spreads easily into narrow gaps, making application straightforward without requiring additional mixing or preparation. When heat-cured, it becomes as durable as firebrick, ensuring your repair performs reliably under demanding conditions. The non-asbestos formula works on cast iron, steel, and firebrick surfaces commonly found in heating systems and chimneys.
