I have a loose brick on a recently made tree well. I have Quikrete Type S mortar and I'm planning on getting a trowel. What are the steps to remove the existing mortar on the brick (which is completely loose at this point) and fix it back on? Did it come loose for any particular reason?
I'm thinking of adding water to the mortar to start after removing existing mortar using a trowel or hammer to loosen the mortar debris. Any recommendations would be appreciated.
