 above the average DIYers. But what I've done is I found areas in the concrete that weren't that visible, like on the side or the bottom of the step or slightly below grade. And I've used a drill, a hammer drill, which is a masonry drill and drilled out some test holes and collected the chips because that dust is the same color as the rest of the concrete. And then I sprinkle that over the caulk and tap it down with my fingers and it blends in perfectly with the surrounding surface.
