We had some lights mounted to the brick on our fireplace. My wife says they have gone out of style and she bought some new ones to take their place. As luck would have it the mounting holes for the new lights are not in the same location as the old lights -- not even close.
I need to fill in a couple holes, about 1/2" in diameter in some brick and also a couple in some black mortar. I hadn't considered using mortar, maybe I should, but if I don't what would be the next best product to use?
Thanks.
