How to fix a stripped hole in a plaster wall

lath-and-plasterscrews

I hired a "professional" painting crew to paint the stairs area, where the crew installed new brackets for the handrail. Unfortunately I did not supervise the work myself. I recently noticed that I have two problems:

  1. The screws for one bracket are not going into a stud! I think the bracket was attached to the plaster.
  2. The top two holes are stripped where the screw will spin freely. I believe that those two screws do not touch the lath board that is behind the plaster.

How should I fix the stripped hole in the plasterboard? Every time I am removing the screws all three holes get slightly larger as a bit of the plaster comes out too.

Should I start using plastic anchors? I'd like to re-use the three #10 1 1/2" screws that came with the brackets if possible.

By the way my house was built in the 1950s.

Screws in wallboard do not support anything. Unless your screws hit a stud or an anchor of some sort, the bracket is decorative, not functional.

If there is not a stud in the immediate vicinity, you need to use a serious anchor. I would recommend using a strap toggle type anchor behind the bottom screw and one of the top screws.

The bolt can be replaced with a flat head version if you need that for your bracket.

I would use a plastic anchor for the third hole.
