Pros and cons- plaster makes a harder wall but it is cooler to the touch.
Plaster is comprised of 3 layers.
Base layer bluerock(sheetrock), wire lath, or plywood, or even durarock (concrete board).
Next layer is a thin layer of concrete (brown coat).
Final layer is a trawled on smooth (concrete).
Using wire lath, or durarock eliminates the growth of mold. Concrete by it’s self it naturally porous.
Water does not get sucked up by the plaster while sheetrock is a sponge.
