JB Weld Fillers & Repairers Features and Benefits

• Two-part epoxy formulation: Resin and hardener are mixed together to create a chemical cure, giving a strong, dependable repair rather than a surface patch.
• Metal bonding and filling: Fills gaps, holes and cracks while bonding to the surrounding metal, so one product handles both jobs.
• Hard-wearing cured finish: Once set, repairs can typically be drilled, tapped, filed, sanded and machined, so parts can be restored to a working profile.
• Resistance to demanding conditions: Cured epoxy is designed to cope with vibration, moisture, fuels and heat to the limits stated on the pack, which is useful in workshops and engine bays.
• Cost-effective repairs: Repairing a part instead of replacing it saves downtime and money.

Frequently Asked Questions

How do I get the best result from a JB Weld metal repairer?

Preparation matters most. Clean the area thoroughly to remove oil, grease, rust and loose paint, then roughen the metal slightly with abrasive paper for a better key. Mix the two parts in the stated ratio until the colour is even, apply firmly, and leave it undisturbed for the full cure time on the pack.

Can I drill or sand a repair once it has cured?

Yes. Once fully cured, JB Weld epoxy repairs can generally be drilled, tapped, filed and sanded to shape. Allow the complete cure time first, as working the material too early can weaken the repair.
