The JB Weld ExtremeHeat Temperature Paste is designed for professionals and DIY enthusiasts who need to perform non-structural repairs on metal components exposed to extreme heat. Its primary benefit is providing a durable seal capable of withstanding temperatures up to 1316°C, where standard compounds would fail. A caveat is that it requires heat activation to cure and is not intended for structural applications. This grey, metallic paste comes in a 6-pack of 3oz tubes, offering a reliable solution for exhaust systems, furnaces, and other high-temperature metal repairs.

The JB Weld ExtremeHeat Temperature Paste is engineered to withstand temperatures up to 1316°C (2400°F).
Yes, the compound cures upon exposure to heat. It requires temperatures above 200°C (392°F) for proper curing.
No, this is a non-structural compound. It is designed for sealing and repairing cracks or gaps, not for load-bearing or structural applications.
It is ideal for repairing and sealing iron, steel, and other metal components exposed to intense heat.
The lifespan of a tube depends on the size of the repair. Each tube contains 3oz of paste, and the 6-pack provides ample material for multiple projects.
The paste cures to a metallic grey finish.
The metal surface must be clean, dry, and free of rust, grease, oil, and contaminants. Light sanding of the repair area is recommended for better adhesion.
Ensure the applied paste is exposed to sufficient heat. The compound requires heat activation. Try increasing the operating temperature of the component or applying external heat source as appropriate and safe.
The application may be too thick, or the temperature fluctuations are exceeding the material's limits for that specific application. Ensure the surface was properly prepared and that the paste is applied within its temperature resistance range. For thicker applications, ensure even heat distribution during curing.
The surface may not have been properly cleaned or prepared. Re-clean the area thoroughly, removing all rust, grease, and debris. Lightly sanding the surface before application can improve adhesion.
Ensure the paste is at a workable temperature. If it's too cold, it may be stiff. If it's too hot, it might be excessively runny. Use a suitable tool like a small spatula for precise application and smoothing.
