I have screw holes which were put in to support a curtain rail. The curtain's been pulled out a few times by accident, and now the screw holes are crumbling and I don't know how to repair that portion of the wall.
I want to get it firm again, then re-drill and put the rail back up. It's a plastered brick wall.
What should I do to repair the crumbling holes in the wall caused by the dislodged screws?
