K2 Exhaust Cement (140g) is designed for fitting and repairing exhaust systems, pipes and catalytic converters on both new and older vehicles. The paste seals holes and cracks effectively and cures to a steel-like hardness at high temperatures. The result is a waterproof, durable seal that neither shrinks nor crumbles.

The product is easy to apply with a filler knife or similar tool directly onto the joint surfaces. Once cured, the seal withstands the heat generated in an active exhaust system. See more K2 products for exhaust systems in our range for anyone needing complementary products.

What sets K2 Exhaust Cement apart?

The cement stands out through its combination of easy application and high heat resistance. It bonds to both metal and previously repaired surfaces, making it suitable for fitting new parts as well as repairing existing holes and cracks.

Once fully cured, the paste forms a solid, waterproof barrier that is not significantly affected by vibrations or temperature fluctuations in the exhaust system. This reduces the risk of new leaks occurring in the same spot.

Frequently Asked Questions (FAQ)

Does K2 Exhaust Cement work for repairing older, rusty exhaust systems?

Yes, K2 Exhaust Cement is suitable for both new and older exhaust systems. The repair surface should be thoroughly cleaned with sandpaper or a wire brush before application to ensure the paste adheres properly.

How long does K2 Exhaust Cement last before it needs replacing or reapplying?

After full curing, around 12 hours without running the engine, K2 Exhaust Cement forms a durable, waterproof seal that withstands vibrations and heat during everyday use. No special cleaning or maintenance is required after curing, but the product should be stored dry and sealed between uses.

What distinguishes K2 Exhaust Cement from other exhaust sealing pastes?

K2 Exhaust Cement cures to a steel-like hardness at high temperatures and does not shrink when drying, unlike many simpler sealing pastes. The combination of waterproofness and stable volume after curing makes the product suitable for both fitting and repair work, whereas simpler products often only offer a temporary fix.
