Fire Barrier Sealant (Pack of 1) Review: Nice product but delivery was mess - Excellent product but desertcart delivery sucks Review: 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. ## Features - Causes serious eye irritation. - Suspected of damaging fertility or the unborn child. - 3M Fire Barrier Sealant is a high-strength, single-component, moisture-curing, gap-filling polyurethane adhesive that creates high strength bonds on a wide variety of materials including plastics, metals, fiberglass and wood.
