Rutland Furnace Cement, Pre-Mixed High Temperature Cement for Metal, Cast Iron and Steel – Repair Wood Stoves, Boilers & Gas Ceramic Logs – Made in USA, Black, 32 oz
This cement is renowned for its long-standing reputation and ability to withstand temperatures over 2000°F. Its smooth, feather-like consistency ensures a tight, smoke-proof seal on metal-to-metal joints and cracked firebricks. Compared with other brands, Rutland’s high-temp cement requires a proper heat cure for longevity, but its durability once cured makes it ideal for extensive repairs. The main tradeoff is that it involves a longer curing process, and improper application can lead to discoloration or failure over time.
Pros:- Excellent high-temperature resistance up to 2000°F
- Long history of reliable performance
- Smooth consistency for thin, smoke-tight joints
- Versatile for metal and masonry repairs
Cons:- Requires a heat cure for optimal durability
- Longer curing time delays use
- Can discolor if not properly cured
Best for: Major stove repairs, sealing cracks, and setting new firebricks
Not ideal for: Gasket sealing or small minor repairs
- Temperature Resistance:2000°F (1090°C)
- Application Type:Pre-mixed, ready-to-use
- Container Size:32 oz
- Material Compatibility:Metal, masonry
- Cure Time:30 days
- Water Resistance:Water resistant
Bottom line: Best for serious repairs requiring high durability and temperature resistance, provided you can manage the curing process.
Rutland Stove Gasket Cement, 2.3-Ounce Tube, Black
This gasket cement is designed primarily for sealing stove gaskets and making small metal repairs. Its ability to adhere fiberglass gaskets to metal and bond metal-to-metal makes it perfect for minor fixes. Compared to high-temp cement, it is easier to apply and cures quickly, but it doesn’t offer the same level of durability for large cracks or extensive heat exposure. The main tradeoff is that it’s less suited for structural repairs but excels in gasket sealing and small crack repairs, rated to withstand 2000°F.
Pros:- Excellent adhesion for gaskets and small repairs
- Quick curing and easy to apply
- Rated for up to 2000°F
- Flexible for gasket sealing
Cons:- Less durable for large cracks or heavy-duty repairs
- Not paintable or suitable for large structural fixes
- Smaller volume limits coverage
Best for: Gasket adhesion, small cracks, and minor stove repairs
Not ideal for: Major cracks, firebrick replacement, or structural repairs
- Temperature Resistance:2000°F (1090°C)
- Application Type:Paste/Tube
- Container Size:2.3 oz
- Material Compatibility:Masonry, metal
- Cure Time:Fast, variable
- Water Resistance:Not water resistant
Bottom line: A dependable choice for gasket sealing and minor repairs where ease of use and quick results matter most.

Factors to Consider When Choosing Best Furnace Cement For Wood Stove
Choosing the right furnace cement for your wood stove depends on the repair scope and your experience. Major cracks and firebrick resets demand a high-temperature, durable cement like Rutland’s high-temp option, which needs proper application and curing time. For gasket sealing and small fixes, a specialized gasket cement provides a quick, effective solution. Understanding application requirements, curing behaviors, and temperature tolerances helps ensure your stove remains safe and efficient.
Major Repairs vs. Gasket Sealing
If you’re repairing large cracks, resetting firebricks, or sealing joints, a high-heat, high-durability cement like Rutland Furnace Cement is essential. For small gasket replacements or minor cracks, gasket cement offers a more manageable, faster option with less curing time but less structural strength.
Application and Curing
High-temperature cement requires a heat cure to prevent discoloration and ensure longevity. Follow the manufacturer’s instructions carefully. Gasket cement typically cures faster and does not require heat curing, making it ideal for quick fixes but less suited for structural repairs.
Temperature Resistance and Compatibility
Both products rated to withstand 2000°F (1090°C) are suitable for wood stoves. Always check compatibility with your stove materials—metal, masonry, or ceramic—and ensure the product matches your specific repair needs.
Frequently Asked Questions
Can I use furnace cement for firebrick repairs?
Yes, high-temperature furnace cement like Rutland’s is designed for firebrick repairs, sealing cracks, and restoring structural integrity. Proper application and a heat cure are necessary to ensure durability and prevent discoloration over time.
Is gasket cement suitable for large cracks?
No, gasket cement is formulated mainly for sealing gaskets and small cracks. For larger or more structural repairs, a high-temp furnace cement is recommended as it offers greater strength and heat resistance.
Do I need to cure high-temperature cement before use?
Yes, most high-temp cements like Rutland’s require a heat curing process to achieve maximum durability. Follow the manufacturer’s instructions carefully, typically involving gradually heating the stove after application.
Can I paint over furnace cement?
While some furnace cements are paintable after curing, many are not. Rutland’s high-temp cement is generally not paintable; check the product specifications if aesthetic finish is important for your repair.
How long does furnace cement last?
With proper application and curing, furnace cement can last for many years, often 10 or more, especially when used for major repairs and sealed correctly. Regular inspections help maintain performance and safety.
Conclusion
If you’re planning major repairs or firebrick replacement, the Rutland Furnace Cement is the best choice for durability and high-temperature sealing. For gasket sealing and minor fixes, the Rutland Stove Gasket Cement offers ease of use and quick curing. Beginners or those with smaller repair needs should opt for gasket cement, while experienced DIYers tackling bigger issues will benefit from the high-temp cement’s strength. Consider your repair scope and application complexity to choose the right product for a safe, lasting fix.
