I just repaired loose bricks on my house in preparation to install new window shutters. When would it be ok to drill holes into the mortar and install the shutters? From my other research I'm going to keep the mortar covered and re-wet it a few times a day for 3 days. Is it safe after that?
Additional information: I completely removed all the old mortar and put in all new mortar for about 11 bricks. It's standard Quickcrete mortar from Lowe's. I made the shutters myself from pine boards. But they are comparable in weight to the composite shutters that were installed previously using the same mounting method.
