I would like to repair a hundred-year-old horsehair plaster ceiling by
attaching new 3/8" blueboard and then skim coating over it. The old
ceiling has some rather large holes in it (too large to repair), so
I'd just like to go over it with new materials.
Here's the catch: There are no wood studs. The building was
converted to condos from an old hotel (circa 1895), and the plaster
ceiling is attached to extruded steel lath (in a diamond pattern, with
holes of about a 1/2") that is attached via steel rods to the steel
and concrete beams that support the building. So, there's no wood to
The plaster will hold a screw, but it's not going into a stud. So
here's my idea: Apply construction adhesive (Liquid Nails) to the
back of each blueboard sheet. Then screw it up on the ceiling. The
glue alone probably wouldn't hold it, and I wouldn't want to rely on
the nails alone, but TOGETHER, I think it will be safe.
So my questions are:
---Is this the best way to achieve this?
---Are there any alternatives, such as using very wide screws that
will grab the steel lath, that you might suggest?
Overall, I'd like to avoid framing, since it will increase the cost
