Can this be used to hold a screw in the side of a fireplace. The screw that holds the chain bracket to close the chimney closed has come out of the fireplace mortar.
Asked by: dhd
This may work to hold a screw as you've described however it is a sealant and not an adhesive so there are some other factors that come into play. If our team can assist please call 1.800.328.1687 M-F 8am-4:30pm CT. Thanks for asking!

We removed the tile surrounding a wood-burning gas fireplace. There is a 1/4-inch gap between drywall and insert on both sides and along the top, and there's now cold air seeping in through the gap. Can we use this to seal the gap?

10.1 oz. Fire-Block Sealant is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Fire Block for Fireplaces I have used this sealant on several occasions over the course of many years on different fireplaces. It has held up wonderfully until I could make permanent repairs as needed. The sealant was easy to apply and held up to the high temos of wood burning fires without worry. I would use this product for this purpose anytime.
