I have a home that was mold mitigated recently.  The walls are plaster
and lath (plaster veneer I believe if there is a distinction between
the two) and the mitigation left 3 bedrooms and two bathrooms with no
blueboard, plaster or lath on the bottom 4 feet of all the walls.  I
am contemplating redoing the plaster myself but I'm getting the
impression there is something of an art to it.  I'm wondering if its
viable for me to tackle this job myself given a certain amount of
handiness (I can drywall and reinstall complete bathrooms, for
instance) and if so if there are newer techniques that might make my
particular situation easier to fix(I understand its normally a multi-coat
process).  If it is not viable I wonder what the odds are it will jibe
with the building code and if a nice join can be made if I were to
demolish the plaster and lath up to the ceiling line and install
drywall in its place (for only the damaged part of the house and
leaving the ceilings plaster)?
