Repair hole in plastered wall (pictures)

[Rått]

I know you can google it, but I want to know how you would have repaired the wall and which products you would use for mortar/render. The construction is not optimal as water accumulates and there is no natural drainage, but I need to make an effort until we redo the entire wall..

Grateful for tips

Cement mortar A, but that wall is unfortunately doomed to break in the future. https://www.se.weber/betong/standardbetong/weber-cementbruk

Agree, you get to cook for the rest of your life. But try pure cement mortar.

Yes. It is doomed. The idea is to chisel away one side so the stairs have one side, and put the railing directly into the step instead of into the wall as it is now.

Thanks for the reply.
