Gray 1/2 Pint High-temp Furnace Cement & Fireplace Mortar – Model 1352

Introducing the gray, ready-to-use high-temperature furnace cement and fireplace mortar in a compact 1/2 pint container. This silicate-based formula resists extreme heat up to 2000°F, delivering durable bonds for masonry and metal components within heating systems. It's ideal for patching cracked firebrick and mortar, and for re-setting furnaces, stoves, chimney collars, boilers, and ductwork with confidence.

Benefits: The pre-mixed, convenient formula speeds repairs and provides a reliable, heat-resistant seal that helps your heating system run efficiently and safely.

Key Features & Benefits:

• Container Size — 1/2 pint jar for precise indoor high-temperature repairs
• Color — Gray finish blends with most fireplace and masonry surfaces
• Temperature Range — Withstands up to 2000°F for dependable firebox, stove, and chimney work
• Pre-mixed & Ready-to-Use — No mixing required, ideal for quick, mess-free application
• Cure & Finish — Indoor use only; 24-hour cure at 60°F minimum; paintable after full cure for a seamless look

Why This Furnace Cement Stands Out: This gray, heat-tolerant mortar delivers lasting performance where high temperatures and tight joints demand reliability. Designed for indoor use, it’s the smart choice for repairing fireboxes, sealing gaps, and maintaining efficient operation of furnaces, stoves, and chimney systems.
