Drywall nails can work
themselves loose, either popping through the drywall or creating a
small bulge on the surface.
Drive a new wallboard
screw into place 2” (5 cm) below the popped nail, sinking the head
slightly below the wall surface. Be sure the screw hits the stud and
pulls the drywall tight against the framing (see top photo), taking
care not to damage the wall surface.
Scrape away loose paint
or drywall material around the popped nail. Drive the popped nail
back into the framing, sinking the head slightly below the dry wall
Using a drywall knife,
cover both the nail hole and the new screw hole with spackle. Sand
and prime the patched areas.

Scrape away any drywall
paper using a drywall knife, if necessary. Sand the dented or gouged

fiberglass and metal repair patches are available. Apply the patch
over the hole. Then coat the area with spackle, blending into the
surrounding wall (see lower, right photo). After drying, sand it
smooth and apply primer.
