We have this giant brick fireplace in a home we just purchased. As part of our renovations, we plan on covering the brick with tile and putting a simpler mantel on top. The hearth and surround was brick and the sides and top edge of the brick was covered by the old mantel.
We removed the brick hearth and had just planned on just covering the old brick surround with tile. When we removed the mantel, we discovered that the builder hadn't finished the brick surround fully because it would be covered by the edges of the old mantel.
Whats the easiest way to ... 'fill in' the unfinished area so we can tile over it.
