I'm working on a house where the owners want a bar with cave-like walls and ceiling. I have a contractor who can do the shaping and finishing of the
surfaces, but he is a waterfeature builder who usually works in rebar and concrete. This will be too heavy for this room since it is on the main floor with a
basement below. The floor is 3/4" advantech on 18" deep truss/joists, 16" o.c. Tentatively, I thought we could panel the walls and ceiling
with 1/2" plywood, add shaped blocks of wood for rough contours, cover it with expanded metal lath, and coat with a plaster or cementitious mixture to
shape the rock. Any suggestions or advice?
