Hey folks, new to the site here and was looking for advice to re attach three pieces of flagstone that have come loose from my walkway . I have attached photos . I was thinking I would first chip out the old mortar . Second clean and wire brush and loose material or dirt away . Third apply a concrete block adhesive and then lay the flagstone back down . 4 th finish up the joints with a mortar joint caulk . Can anyone else offer a different approach or some things to pay attention to ? Thanks
