Brick siding chipping off
Someone drilled a hole through this wall from the outside in for the electrical. The outside is stucco, the inside has brick siding. Under the conduit there are pieces chipping away. I need to fix this so it doesnt fall off and land on a baby. The chunks that are breaking off are about a half inch thick. I was thinking of taking some mortar, adding red coloring (to match the brick) and filling in where the chunks are missing. What do i need to do to get the mortar to adhere to the brick so it wont fall off in the future?
