Can this caulk be used to install an interior garage metal fire door that enters into the house?

Can this caulk be used to install an interior garage metal fire door that enters into the house?
Asked by: Reed
This is simply used to seal openings and is fire rated or heat rated. If you are installing a interior door for the garage to house door, you install that like any other exterior door. Check with your local code, you may just need what is called a 90 minute door, made out of fiberglass or metal coated wood instead of solid metal door. Solid metal is normally a commercial requirement. This caulking would be of little use for the door, as you are better off using brickmold to cover the gap between the door casing and the rough opening studs.

No this is only an hourly rated fire barrier and not intended for long term exposure to fire. Home Depot sells a mortar repair by the tube for extended exposure part number 105492 manufactured by Quikrete

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
