Answer

This product is not specifically designed for outdoor use, if may work but breakdown and begin to leak overtime. It is also not required as a hourly rated fire block is not needed to the outside. I would recommend a high temp silicone sealer like the Rutland brand high temp silicone, which is designs for exterior use.

Not really a good application for this product. this caulk is an intumescent caulk, which means it will expand quite a bit if it gets hot. It would be better to use something like the DAP brand high heat mortar caulking.

Works great for me!
I used this to seal the gaps between the firebox and cook chamber in my new meat smoker. It was easy to apply and dried within 30 min to the touch.

Cured in the Tube
This tube must've been very, very old as it was cured in the tube. No date of manufacture was on the tube, so there is no way of knowing how old it was. I'll never buy perishable items like this at this location again.

Response from 3M Product ExpertMay 29, 2015
We are sorry to hear the caulking was dried in the tube when you purchased it. This certainly is not what we would expect and would like the opportunity to correct it. We would ask you please contact us directly at 1-800-328-1687 option #7 so we can offer assistance. Thank you for leaving your review.
