Firebox sealant?
Hi,
We have an 70 year old fireplace and the grout/sealant between the firebox and the surrounding flagstone is crumbling, leaving a gap of around 1/2". I've used a caulk like sealant in the past on other projects to seal small gaps but this gap is too large for this. I see there is some mortar & cement out there that looks to be more appropriate - what would you guys recommend? The gap around the firebox runs probably around 10'.
Thanks!

Try Rutland Fireplace Mortar. It comes in a tube and is applied with a regular caulk gun. It's gooey when it goes on, but then, within 30 days, needs to be fired at 500 deg F, or higher, to achieve full strength. I would buy just one tube and see how it does. Let us know.
