[Shop-talk] Porch Ceiling

[Ron Schmittou]

Unless you like the ripple effect - you will need to glue the back even if
you nail it.  As below strip as much paint of the drywall then you can paint
the backside and nail in place.  Regular cheap paint works for this instead
of a heavy adhesive that may not spread evenly - just make sure the drywall
is exposed enough for the moisture from the paint to absorb into it.

  Bob,

As others have said, you can nail wood onto the joists to bring your 
spacing back to 16" centers, but there is another problem that needs to 
be dealt with. 1/4" plywood will sag when nailed on 16" centers\ over 
time, leaving you with a wavy ceiling.
