I took out a wall in AC unit from a rowhouse wall and was attempting sawtooth new bricks in to help remove any evidence of the AC in the wall. In doing so, I have 2 challenges.
One brick cracked off in 2 pieces , but the dislodged portion covers little area on the face. It starts from the bottom corner and to the top about an inch over on the 8 x 2.25 inch brick. My question here can I simply slide it back in place - or should I replace it which means more drilling and cleaning. Its getting close to the edge of the wall.
The AC chassis was about 25.5 inches wide so I have about 1.5 inches to fill - how thick can vertical mortar be? The existing mortar elsewhere is very thin - like 1/8 inch but vertical joints shouldn’t be so noticeable- right? Also, I plan to have someone paint the brick in the end :).
