What Customers Are Saying

The product is effective at sealing holes and gaps to prevent the spread of fire, with a durable, fire-rated formula providing up to 4 hours of protection. It is easy to apply and the red color makes it simple to see where it has been used. However, some customers have reported issues with the caulk being too thick or dried out, making it difficult to dispense, and a few instances of poor adhesion or the caulk coming out in chunks over time.

Not worth it.

Would Not Recommend

Expensive. Difficult to use. Tended not to stick to the wiring or the wood. Required two applications to seal the hole.

Cool red color

Would Recommend

Product works, but it down not apply as smooth/easy as other silicones or caulks. The paste feels dry and stubborn to flow freely from tube. It needs application gun strong pressure.
