‘Tis but a scratch
The thing about mortar is that it doesn’t last forever, but with some quick thinking and a bit of engineering skills, you too can prevent your home from disrepair by fixing cracked mortar with a bit of tape. In this picture, that’s exactly what this homeowner did, and it appears to have done the trick.
However, you can also see that there’s fresh mortar beneath the tape that is waiting to dry. So, perhaps tape isn’t the only thing you should use in such a scenario, especially if the risk of doing it the wrong way is your home’s wall collapsing into your living room, exposing your way of life to passersby.
