Can it be used to seal crack between fire rated gypsum board and wood stud l in the firewall? Will it stick good to both drywall and wood stud?
Asked by: Lena
It can stick to anything. To maintain a smoke barrier it can seal any crack between any surface. In a fire rated assembly it can seal a gap between drywall and any non flammable item. In this assembly exposed wood needs to be covered with fire rated drywall and then any gaps can be sealed with this product

At what temperature does this product start to expand? (Says it will expand when exposed to heat)

Asked by: DIYdude
It will expand to 3 times it’s dried volume at temperatures above 1000 degrees F. That’s according to the spec sheet that can be accessed on this web site.

can i use this to seal around metal pipe in the chimney flue?

can i use this to seal around metal pipe in the chimney flue?
Asked by: ben
No. This product is designed to expand at a higher temperature. When that happens it'll cause the metal pipe to become disfigured leading to exhaust loss into your home. The correct product to use will be FB136, which can withstand temperature up to 1300 F and does not expand. The caveat is will require at least once yearly review to make sure its not too brittle and falling off. In which case a quick re-apply will suffice.

Rated 5 out of 5 by from I am rating this a 5 based on the condition of adhesion, cohesion and general ease of application... I am rating this a 5 based on the condition of adhesion, cohesion and general ease of application with which the product was intended. I filled around electrical wiring and schedule-40 pipe. It adheres to all surfaces - wood as well. It's consistency keeps it from slumping and falling out of the openings in which it is placed. However, I did take a piece of wood to mash the product into place in difficult to reach or deep areas. I was also able to build up the product for larger deeper openings. The cured product results in a firm but somewhat flexible filler. One frustrating note with this product was that when the pressure was released from the caulking gun plunger the caulking continued to run out. Leaving pressure on the gun plunger is not advised unless you want a generous, and expensive, pile of caulk wherever you set down the gun.

Rated 1 out of 5 by from Very Disapointed !! I'm very disappointed with this product. I spent all day making custom flashing for stove pipe installation. Which came out perfect the last thing I did was to use this 3m fire sealant to fill in a 1/16 inch seam. The stuff barley squeezed out of the tube, it was very dry. It said it had a fast dry time, I don't consider 2 days fast. I regret using this stuff. I wouldn't recommend it to anyone.
