Hello community, I noticed that this stair step in my european 60ies house was a bit cracked so I broke it off completely. How would you fix this? Some mortar or tile glue? Does it need some kind of rebar?
Update: I finally fixed the stairs by glueing things back on with flexible tile glue and finishing up with the thing you use to put in the groves between tiles. It seems sturdy until now :)
