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.

10.1 fl. oz. Red Fire-Barrier Sealant Caulk CP 25WB Plus is rated 4.2 out of 5 by 72.
Rated 5 out of 5 by from Great product... Great product

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.

It really needs a cap after opening. It dries out if not used at once. Putting a nail in opening leaves contaminates that pollute our use but helps to keep from drying out.
