I bought a cheap house last year because o couldn’t afford renting anymore. I thought I would be able to get loans to fix it, turns out I was wrong . So now I’m starting the hell if fixing things on my own.
It won’t let me post pictures so I’ll describe it the best I can.
The home is from 1952 and has a concrete back porch attached to the house. It’s that type of concrete with the rocks in it.
It has been painted multiple times and the paint is peeling/gone in certain areas.
The steps have 2 small holes the rocks are falling out of. They t Jase some deep crack and chunks combing off on the covered porch part.

What can I use to repair and seal it?
