Trusted 3M Product for Firestop Applications
I used this sealant for a firestop application where penetrations needed to be properly sealed, and it performed exactly as expected. The caulk applies smoothly with a standard caulk gun and has a workable consistency that makes it easy to fill gaps without excessive dripping. As expected from 3M, the product feels professional grade and is clearly intended for code-compliant fire barrier installations rather than general household caulking. The bright red color also makes it easy to identify after installation. If you're looking for a fire-rated sealant for the appropriate application, this is a reliable option from a trusted manufacturer. Be sure to verify that it meets the requirements of your specific project.

fire barrier sealant works well
sealant worked as advertised....would be nice to have in a smaller tube, as a lot will probably be discarded due to non-use....

Makes the inspector happy
I think I actually pay more money in labor to install this stuff than to buy it.

Seems to be a great product.
Works well, seems to set up well, just a little messy to clean up. Other than that seems to be a great product.

Fast and Easy
This sealant is easy to use in a caulking gun. It is easy to smooth and cleans up quickly. I am confident and happy the cracks in my fireplace bricks are sealed for the season.

Amazing
I cannot speak to it's fire rating as we have not had a fire but this product's consistency, spreadablility and use of fiber in the mix creates the perfect product for us. We use it to fill gaps in a woodstove. And also spread on wood that is near a stove vent pipe. It does not get super hot but we take all precautions. This goes on good with gloved fingers, a good thickness and the fibers keep it where you put it.
