We recently removed an old air conditioner from the front of my son's home. His home was built in the '70's, and we were unable to find the brick that matched it. It is all red and has a kind of combed look to it. We used brick left over from when our home was built-1994. We didn't think it would be as obvious a mismatch as it is, not only the brick, but the mortar. His was on the old ivory side, what we used was grey. I think that I might be able to top the mortar with a repair mortar in a better matching color, but Is there a way that I can put something on the bricks to match the old ones? Can I use a brick colored mortar and try to match the combing effect? Maybe there is just a good paint that I can use to match it? Help!
