My fireplace insert has a metal surround which overlaps the back hearth. On each side there is about a one inch gap between the edge of the surround and the edge of the tile, revealing a strip of mortared surface. The surface is about as smooth as you can get a vertical mortar coating with a trowel---good, but not glassy smooth. To keep this nagging detail for dragging on forever, my wife and I have decided that it might be enough to simply paint the narrow surface the same flat black color as the surround. Hopefully this will make it disappear, more or less. If it isn't good enough, and we decide to find edging tile to finish it, will thin set mortar stick to the painted concrete surface well enough to finish the job, or would I end up having to remove the paint?
