Hey elevatorman,


Thanks for joining us here on the community!


You essentially answered your own question for how to repair your loose slate step!


Just make sure that you clean the bottom base via scrubbing using a steel brush. Once that is done, you can use a small amount thin-set mortar to successfully bond it to the step base. If the joints were already mortar, you can grout it with that.


Sealing the tiles and grout joints after they have dried is equally important. This helps to prevent cracking via water seeping through it, and helps prevent things like this from happening again.

Let me know if you have any further questions,
