A coating for wall construction is provided whereby a level 5 finish may
be obtained without the need for a finishing coat or final skim coat. The
coating may be applied to drywall elements prior to installation and is
compatible with jointing materials such that a substantially homogeneous
surface may be obtained after the drywall elements are assembled with
jointing material and the jointing material is dried. The coating
formulation includes a noncellulosic thickener, a binder, a mineral
filler and water. A method for the construction of interior walls and a
construction assembly for interior walls is further provided.
