Well done. Now pick up a concrete grinding wheel, (the type that fits on a corded drill) and work it out nice and even.

Yeah, if you never do any DIY house projects, it's probably not the best first one. But, it was easier than I thought. I used an inexpensive concrete cup wheel (this one: https://www.amazon.com/DEWALT-DW4961-Concrete-Masonry-Grinding/dp/B000R92HO6/) on edge, because I didn't want to pay for a fancy purpose-specific crack chasing attachment. Best tip: wet the concrete first. It minimizes dust, and it makes this cup wheel less aggressive and easier to control.
I'm currently working on filling a seam between the concrete garage bay of my shop, and the wood floor side of the shop, which is bordered by 2x4 lumber in the floor. So there's this 1/2"-1" gap, with concrete on one side of the floor, and 2x4 on the other. I'm thinking of just using the same technique: grind down a bit and then fill with 2-part epoxy. Sound reasonable? I'm tempted to use Bondo all-purpose putty, because it specifically says it's for wood and concrete, but I'm hesitant to use it on a surface that not only gets walked on, but has equipment rolled over it. What do you think?
