I live in the top floor apt of an eight story building which was built in 1926. My ceiling is lathe and plaster and I can tell from a hole in the ceiling, that there is a 6" gap between the lathe and plaster and the building's actual ceiling.

Can I drywall right over the lathe and plaster ceiling? What precautions must I take?

Thanks,
Mike
