Description
Heat Resistant Fire Cement for Stoves, Fireplaces & Flue Systems
Firecement HT is a ready-to-use, high-temperature fire cement designed for sealing, repairing and installing components exposed to extreme heat. The hard-setting formulation creates a durable, heat-resistant seal that withstands temperatures typically encountered in stoves, fireplaces, flue systems, boilers and heating appliances.
Ideal for both domestic and commercial heating applications, Firecement HT provides excellent adhesion to masonry, fire bricks, concrete and metal components. Once cured, it forms a rigid seal capable of resisting direct exposure to high temperatures without cracking or breaking down under normal operating conditions.
Suitable for installation, maintenance and repair work, Firecement HT is commonly used for sealing flue pipes, repairing firebacks, fixing fire bricks and sealing joints around heating appliances.
