Hello good people!
I've been looking around for how to repair my basement stairs and plastered walls, but I'm not finding any clear answers.
I tried fixing a step last summer, but it didn't hold up at all during the winter as it cracked and pieces came loose. I'm attaching some pictures.
I have no idea what type of concrete or plaster it is, and as I understand it, that's relevant for repairs.
I myself don't have much experience with repairs, but I would think that you need to remove the outermost material to be able to get a larger surface to attach to.
Just saw the repair and adding:
Maybe you need to drill rebar into the old structure to hold it together.
