Any chance that you folks are punching holes in the walls with
doorknobs? If so, buy some baseboard "bumpers" for the doors
before making your repairs.
One good repair method involves cutting an oversized patch from
scrap drywall. In your situation with a 3" hole, the patch should
be about 7" in diameter. In the center of that patch, draw a 3"
circle on the back side and carefully cut as deep as you can around
that circle without cutting through the front paper. Remove the disk
of material, leaving a 3" plug of drywall whose front paper covering
has a 2" lip all the way around. The rest should be obvious.
A second good method involves a simple 3" plug of drywall material.
Before installing the plug, put a piece of wood (eg: 3/4" x 1/4" x 6")
inside the hole and attach it to the back of the hole with drywall
screws - one on either side of the hole. So, looking at the hole you
would see the hole with a drywall screw head countersunk in the
wall just an inch or so to the left and to the right of the hole.
And inside the hole you would see the piece of wood which will stop
the plug from dropping behind the wall. When you insert the plug,
you can attach it to the piece of wood with 1 or 2 countersunk
You can also check at your local hardware stores for products designed
for repairing drywall holes.
1. Cut out another piece and stick it in, and fill up the edge crack?
2. Cover it with gauze and then fill from there.
Any tips welcome. I have a few to do!
