Threshold repair help

[Michael Miller]

Hello! I'm new to this forum and could use some advice.
I'm helping a friend repair a stone sill on his 1920's home front door. Beneath the brass threshold (all the screws into the stone had failed) there is a divot in the stone and a chipped edge. We'd like to square it up and level it with some sort of patching material.

It's a small repair but at a heavy-traffic spot so it needs to hold. A brick-layer I once hired called these stones "Farmington" sills. Not sure if that helps.

Any advice on material/products will be greatly appreciated! MM in the "216"

hey, welcome to the forum, man. this is a perfect job for an Epoxy Based Stone Repair Mortar. because it's a high traffic area (a doorway sill), you need something stronger than a typical exterior cement patch.
Brands like Aboweld or specialty epoxy kits are designed to be stronger than the stone itself, hold up to stepping, and won't pop out with freeze/thaw.
Clean out the divot well, prep it with a bonding agent if the instructions say so, and fill it with that epoxy

I usually use Bonstone Last Patch Limestone, it's great. water absorptive patch compound with UV stability, specifically for aesthetic and foot traffic repairs on limestone and sandstone
